The Complete Toilet Buying Guide: Types, Features & What to Avoid (2026)
24"-27"
Target total depth for a small bathroom toilet - this is the front-to-back projection range that qualifies as "compact" versus the standard 28-30" elongated range
21"
Minimum front clearance required by current IPC code - the distance from the front of the bowl rim to any wall or obstacle. This is your hard constraint in any small bathroom.
10"
Rough-in size found in millions of older US homes - pre-1970 townhouses, city apartments, and regional builds in the Northeast and Midwest. Standard is 12"; always measure before buying.
#1
Mistake buyers make: buying by looks first without checking projection depth. A toilet can be beautiful and still be 30" deep - 3-4" too much for many powder rooms and tight layouts.

The best toilet for a small bathroom is the one that actually fits your room - not just in the rough-in sense, but in total projection from the wall, side clearance, and door swing clearance. Every other quality (flush performance, design style, seat comfort) becomes irrelevant if the toilet turns a tight powder room into an obstacle course. Most guides show beautiful compact toilet photos without giving you the front-to-back depth number - the single measurement that determines whether a toilet works in a small space or makes it feel half its actual size.

This guide fixes that. Every toilet pick here includes the full projection depth, the rough-in it fits, and the specific room types it suits - powder room, half-bath, small full bath, or apartment bathroom. All picks come from Bathify's Swiss Madison lineup, which happens to be one of the most space-efficient toilet collections available in the US market, combining skirted one-piece construction with dual flush efficiency and modern European proportions that read as stylish rather than just small.

The three numbers you need before reading any product picks

Rough-in (wall to drain center - usually 12", sometimes 10" or 14"). Total room depth from the toilet wall to any obstacle in front (opposite wall, door swing, vanity corner). Side clearance from the drain centerline to each side wall or fixture. If you don't have these three numbers, the rest of this guide is decoration. Measure first. Every product pick below includes what it needs from each measurement to work in your room.

● ● ●
Quick answer by room type

For powder rooms and tight half-baths: round bowl compact 1-piece or wall-hung. For small full baths: compact 1-piece with skirted trapway. For older homes with 10" rough-ins: the Concorde or St. Tropez 10" models.

The specific recommendation ladder: if your room depth is under 56" (wall to obstacle), you need a toilet with under 27" total projection - go round bowl or wall-hung. If your room depth is 56"-62", a compact elongated 1-piece works. If you have a 10" rough-in, your choices narrow significantly - the Swiss Madison Concorde and St. Tropez are the strongest 10" rough-in options at Bathify. If you want maximum space recovery and have the budget for in-wall installation, a wall-hung toilet from Bathify's Swiss Madison lineup opens up the floor completely and creates a dramatically larger-feeling room regardless of actual square footage.

Measure First: The 4 Numbers That Determine What Fits

Before a single product recommendation is useful, you need four measurements. Write them on your phone before you read another word about specific models. Getting even one wrong is the most expensive toilet shopping mistake possible - toilets are not returnable once installed.

Measurement 1
Rough-In
Distance from the finished wall (not baseboard) to the center of the floor drain bolts. Standard US = 12". Older homes: 10" or 14". This is non-negotiable - a mismatch means the toilet won't fit the plumbing. Measure by pulling up bolt caps and measuring to the center of each bolt, then averaging if they differ slightly.
Measurement 2
Room Depth
From the finished wall behind where the toilet sits to the nearest obstacle directly in front - opposite wall, inside of door when open, vanity corner, or shower entry. Subtract 21" (the IPC minimum front clearance) to get your maximum allowed total toilet projection. Example: 52" room depth → 52 − 21 = 31" maximum projection. Anything under 27" projection is "compact."
Measurement 3
Side Clearance
From the drain centerline to any wall or fixed fixture on each side. IPC minimum is 15" each side (30" total width centered on the toilet). Recommended for comfort is 18" each side (36" total). If you're under 15" on either side, the toilet placement needs to move or the fixture arrangement needs to change before a new toilet solves anything.
Measurement 4
Door Swing
Swing the door to its widest open position and mark the arc on the floor with tape. The toilet's front rim cannot fall within this arc. Many powder rooms have doors that open into the toilet's projection zone - a detail that forces a round bowl, compact elongated, or outswing/pocket door solution that most guides never mention.
Pro Tip

Simulate the toilet with cardboard: Cut a cardboard rectangle to your target toilet's depth and width (use the product's "overall depth" and "overall width" specs, not just the bowl dimensions) and tape it to the floor in the toilet's intended position. Walk around it. Open the door. Sit in a chair the same height as the toilet. This 5-minute test eliminates more bad purchases than any amount of measuring alone.

Regulatory context
Code Clearance Requirements - What the 2024 IPC Says

The 2024 International Plumbing Code (IPC), which most US states and municipalities have adopted in whole or in part, specifies the following minimum clearances for residential toilet placement:

Clearance Type IPC Minimum Recommended (Comfort) Why It Matters for Small Baths
Front clearance (bowl rim to obstacle) 21 inches 30 inches The binding constraint in most powder rooms - determines maximum toilet projection depth from back wall
Side clearance (centerline to wall/fixture) 15 inches each side 18 inches each side Limits how close a toilet can be to a shower, tub, or side wall - determines minimum bathroom width for toilet zone
Total toilet zone width 30 inches (15+15) 36 inches (18+18) Small bathrooms often have only 30"-36" available - side clearance is frequently the binding constraint in narrow rooms
Above seat clearance No code minimum specified 24-36 inches from seat to any shelf or cabinet Relevant for powder rooms with floating shelves or vanity mirrors directly above the toilet location
⚠️ Local code variations: While the IPC sets the baseline, some states and municipalities have adopted modified versions. California, New York City, and Chicago have specific local amendments. In older buildings with pre-existing non-compliant layouts, replacement toilets are typically "grandfathered" as long as the new toilet's footprint doesn't extend beyond the old toilet's footprint. Verify with your local building department if you're doing a significant bathroom remodel in addition to a toilet replacement.

Configuration options
4 Toilet Configurations That Work in Small Bathrooms

Not all compact toilets are created equal - different configurations save space in different ways, and each has a specific use case where it outperforms the others.

Configuration Typical Projection Space Strategy Best For Trade-off
Round bowl 1-piece (skirted) ~24-27" Shorter front-to-back projection than elongated; skirted trapway eliminates side bulk Powder rooms, tight half-baths, any room under 56" depth Less comfortable for tall adults vs. elongated; slightly less seat surface area
Compact elongated 1-piece ~26-28" Oval bowl retained for adult comfort; overall depth trimmed vs. standard elongated Small full baths, larger half-baths with 58"+ depth Still 2"+ more projection than round; selection is narrower
Wall-hung (in-wall tank) ~14-18" bowl only Tank hidden in wall; only bowl projects into room; floor is fully open for visual space gain Any small bathroom - the ultimate compact solution for modern remodels Higher install cost ($600-$1,500 labor + carrier); wall must be opened
Tankless (electric or pressure-assist) ~20-24" No tank at all - connects directly to water line; dramatically reduces back projection Bathrooms where back clearance (to supply valve, baseboard) is very tight; modern aesthetic Requires electrical hookup or adequate water pressure; premium price point

Matte Black / Dual Top

The Sublime II in its round compact configuration is the closest thing Bathify's lineup has to a purpose-built powder room toilet. The round bowl trims front-to-back projection versus the elongated bowl version, and the fully skirted trapway eliminates the exposed plumbing that makes smaller toilets look utilitarian rather than intentional. The dual flush top-button actuator adds a clean, European-influenced look that reads as premium in a small space rather than as a budget compromise.

The non-porous, scratch-resistant ceramic is a practical advantage in any high-frequency small bathroom - powder rooms tend to get more guest traffic per square foot than any other bathroom in the house, and a surface that resists mineral deposits and staining stays looking new with minimal maintenance. The fully glazed trapway is specifically relevant in smaller bathrooms where plunging is more disruptive: a fully glazed interior dramatically reduces clog frequency by keeping water flowing freely through the bowl exit.

Available in white and glossy black - the black option is one of the few genuinely striking compact toilet choices in this price tier, and in a well-designed powder room with contrast tile or dark wall treatment, it functions as a design statement rather than a utilitarian fixture. Shop the Sublime II and all 1-piece toilets at Bathify.

Ideal room depth: 50"-60" from back wall to obstacle Why it wins: Skirted + round + dual flush + black option Limitation: Standard height - not ADA; not ideal for tall adults as primary toilet

Glossy White / Black / Bowl Only

Wall-hung toilets are the only configuration that creates actual floor space rather than just measuring smaller. By mounting the bowl to a steel carrier frame inside the wall - with the tank concealed behind the wall surface - a wall-hung toilet removes 12-18 inches of total depth from the room and opens the floor entirely below the bowl. In a small bathroom, an open floor line is one of the most powerful visual tricks available: it makes the room read as larger and cleaner in a way that no amount of paint color or mirror placement fully replicates.

The Swiss Madison Concorde wall-hung (square bowl, $219.99 at Bathify) and Ivy wall-hung (elongated bowl, $196.99 at Bathify) both use a 0.8/1.6 GPF dual flush system - the most water-efficient configuration available in Bathify's lineup. Both use a removable actuator plate for plumbing access without opening the tile, which makes future maintenance far less disruptive than the traditional objection to wall-hung toilets suggests. The adjustable height is a genuine functional advantage: set the seat at the exact height that works for the household's primary users, including ADA-compliant heights for aging-in-place setups.

The installation investment is real - expect $600-$1,500 in labor for a professional wall-hung installation including the in-wall carrier frame and tile work - but in a bathroom that will be used for 20+ years, the space and aesthetic return is among the highest per dollar of any bathroom investment. For a full walk-through of wall-hung toilet installation and what to expect, see our wall-mount toilet guide. Shop wall-hung toilets at Bathify.

Bowl-only projection: ~14-18" - the most compact option by far Height: Adjustable to any ADA-compliant position Best water efficiency: 0.8 GPF light flush - lowest available in US residential Trade-off: Requires new rough-in wall work - $600-$1,500 install labor

Glossy White / Single - Left / Chrome

The Swiss Madison Carre is the pick for homeowners who want their small bathroom to look intentionally designed rather than just space-efficient. The square bowl profile - paired with the skirted trapway and top-button dual flush actuator - creates a geometric precision that photographs exceptionally well and reads as far more expensive than its ~$370-$400 Bathify price point. In a modern or contemporary powder room with large-format tile, matte black hardware, and a minimalist floating vanity, the Carre functions as the visual anchor of the room rather than a necessary fixture to work around.

The square bowl design also has a practical space argument beyond aesthetics: square bowls distribute seating area differently than round, providing more usable seat surface toward the sides rather than the front, which some users find more comfortable despite the similar overall bowl dimensions. The skirted construction eliminates the crevices and exposed bolt hardware of traditional toilets - in a small bathroom where the toilet is visually unavoidable, a clean skirted profile reduces visual noise. Shop the Swiss Madison Carre at Bathify.

Design style: Geometric modern · Pairs with matte black, brushed gold hardware Best for: Designer powder rooms, modern half-baths, renovation showcases Limitation: Square bowl seat is less available as aftermarket replacement than round/elongated

Glossy White

The 10-inch rough-in is one of the most underserved specifications in US toilet retail - most guides treat it as an edge case, but millions of American homes built before 1970 in the Northeast (New York, Boston, Philadelphia), Upper Midwest (Chicago, Detroit, Cleveland), and Southeast have 10" rough-ins as a regional building standard. Buying a 12" rough-in toilet for a 10" space creates a 2" gap between the tank and the wall that is immediately obvious and nearly impossible to hide cleanly.

The Swiss Madison Concorde 10" rough-in at $373.99 at Bathify is the only Bathify model explicitly designed for this specification, making it the clear recommendation for anyone dealing with a pre-standard rough-in in a small bathroom. It brings the same skirted square bowl design, dual flush 1.1/1.6 GPF system, and fully glazed trapway as the 12" Concorde - just calibrated for the tighter rough-in distance. If you're in an older city apartment in Manhattan, Brooklyn, Chicago's North Side, or a pre-war Boston triple-decker, this is the model you need. Shop the Swiss Madison Concorde 10" at Bathify.

📐 How to confirm you have a 10" rough-in: With the existing toilet in place, measure from the finished wall (not the baseboard) to the center of the nearest floor bolt. If that measurement is 10"-10.5", you have a 10" rough-in. A 12" rough-in will measure 12"-12.5". Don't guess - a wrong rough-in purchase cannot be corrected without plumbing work.

Glossy White / Smart Bidet

For small bathrooms that are getting a full renovation and have a premium design direction, the Swiss Madison Viro Smart Tankless is the most architecturally clean floor-mounted option in Bathify's lineup. Without a tank, the toilet's profile against the wall is dramatically flatter than any tanked model - the back wall reads as clear and open rather than interrupted by a ceramic tank block. In a small bathroom, this visual clarity makes the space feel less occupied even though the total square footage hasn't changed.

The Viro's Dual Vortex flush creates a cyclonic rinsing action throughout the bowl using a minimum of 1.1 GPF - a self-cleaning effect that reduces manual scrubbing in a bathroom where the toilet is frequently visible and often used as a design centerpiece. The touchless auto flush, side button, and foot kick options mean hands-free operation - highly appropriate for a powder room where guest hygiene is a priority. The battery-operated solenoid valve requires no electrical hookup, which simplifies installation in bathrooms without convenient outlet placement near the toilet location. See the Swiss Madison Viro at Bathify.

Key advantage: No tank = cleanest wall profile of any floor-mounted toilet Smart features: Auto flush + foot kick + side button Best for: Premium powder rooms, modern full remodels, ADA comfort height

The Swiss Madison St. Tropez in 10" rough-in configuration is the more accessible-priced alternative for homeowners with non-standard rough-ins who want a skirted, modern 1-piece toilet without the premium price of the Concorde square bowl. The Mediterranean-inspired design is smoother and more curvilinear than the Concorde's geometric square aesthetic - it pairs well with traditional tile patterns, warm color palettes, and more classic bathroom finishes common in the pre-1970 homes that often have 10" rough-ins.

The soft-close, quick-release seat is a meaningful daily quality-of-life feature: the quiet close is more important in a small bathroom where the toilet sound carries further in the tight space, and the quick-release mechanism makes seat removal for deep cleaning easier than traditional bolt-mounted seats. Shop the Swiss Madison St. Tropez 10" at Bathify.

Best for: 10" rough-in homes wanting skirted 1-piece without square bowl Design: Curvilinear Mediterranean - pairs with traditional and transitional styles Feature highlight: Soft-close quick-release seat included

Design Tips: Making a Small Bathroom Toilet Look Intentional

A compact toilet in a small bathroom doesn't have to look like a compromise. These are the specific design moves that change a small bathroom toilet from "the thing that takes up too much space" to a designed fixture that reads as part of a considered room.

1. Match the toilet color to the wall, not the fixtures

A white toilet against a white wall visually disappears - it reads as built-in rather than placed. A white toilet against a dark or colored wall becomes the visual focus of the room, which is appropriate only if the toilet is genuinely beautiful (like the Carre or Viro). For powder rooms with bold wall treatments, a matte black toilet (Swiss Madison Sublime II black) can be used intentionally as a graphic element against a light wall.

2. Choose skirted trapway toilets exclusively for small spaces

In a small bathroom, the toilet's sides are always visible. An exposed trapway - the curved pipe section visible on non-skirted toilets - adds visual clutter that makes the toilet look larger and bulkier than its actual dimensions. Every Swiss Madison model at Bathify uses a fully skirted trapway, which creates a smooth, uninterrupted profile from any angle. This single design feature does more for perceived room size than almost any other toilet design detail.

3. Hang a narrow floating shelf above the tank, not beside the toilet

In a small bathroom, positioning storage beside the toilet (freestanding shelving units, ladder shelves) adds furniture that further crowds the space. A narrow floating shelf directly above the toilet tank uses vertical space without adding floor or wall footprint. Keep it under 8" deep and limit accessories to two or three items - a small plant, a candle, and a soap dispenser is the standard that works in nearly every small bathroom photography reference.

4. Use the toilet's back wall for a bold finish, not above the toilet

In a powder room, the wall directly behind the toilet is one of the most photographed walls in any home (it's visible from the doorway). Using a distinctive tile, wallpaper, or paint color on this wall draws the eye to the wall treatment rather than the toilet dimensions. This is the design principle behind the "statement powder room" that's dominated Pinterest and Instagram since 2020.

Design Tip

Replace the floor-mount water supply line with a braided stainless line angled toward the wall: A standard white plastic supply line hanging visibly between the shut-off valve and toilet tank is one of the most consistently overlooked design details in small bathrooms. A neat braided stainless line, routed tight to the wall and secured with a clip if needed, removes a visual distraction that's surprisingly noticeable in a small room where every detail is visible from the doorway.

By room type
Which Toilet for Which Room
🚪
Powder Room / Half-Bath
Round compact 1-piece or wall-hung
Typically 36"-48" wide × 48"-60" deep. Front clearance is almost always the binding constraint. Round bowl (saves 2" vs elongated) or wall-hung (saves 12-18"). Sublime II Round or Concorde/Ivy wall-hung are the picks.
🛁
Small Full Bath (with tub/shower)
Compact elongated or round 1-piece
Typically 60"-72" wide × 84"-96" long. Side clearance (toilet to tub or shower) is often the constraint. Skirted 1-piece reads better in full bath context. Sublime II elongated or Carre are best picks here.
🏢
NYC / Chicago Apartment
10" rough-in model or wall-hung
Pre-war buildings frequently have 10" rough-ins. Measure before anything else. Concorde 10" or St. Tropez 10" are the floor-mount solutions. Wall-hung requires carrier install but delivers the most space in the tightest urban layouts.

Final Verdict

Measure the room before picking the toilet. For most small bathrooms, a round-bowl skirted 1-piece or a wall-hung gives you everything - space, style, and performance - without compromise.

The best toilet for a small bathroom is the one sized correctly for the specific room first, and styled appropriately second. Every pick in this guide from the Bathify Swiss Madison lineup solves a specific space problem: the Sublime II Round for standard powder rooms and tight half-baths; the wall-hung Concorde and Ivy for maximum space recovery in full remodels; the Carre for design-forward small modern baths; the 10" rough-in Concorde and St. Tropez for the millions of older US city homes with non-standard plumbing; and the Viro Smart Tankless for premium projects where an ultra-flat profile is the design priority.

For most homeowners: measure your rough-in, confirm your room depth with the 21" front clearance subtracted, and if the result leaves you under 30" for the toilet, go round bowl compact 1-piece. If you're doing a full bathroom remodel and the budget allows, the wall-hung option changes the room more dramatically than any other single fixture decision.

For older city homes: confirm the rough-in measurement before you read another product description. If it's 10", your choice is the Concorde 10" or St. Tropez 10" at Bathify - both are excellent toilets, and both save you from the gap-behind-the-tank mistake that defines too many urban apartment bathroom installations.

Common questions answered
Frequently Asked Questions
Q
What is the smallest toilet available for a powder room?
The most compact floor-mounted toilet options for powder rooms and tiny bathrooms in the US market measure approximately 24-26 inches in total front-to-back depth (from the finished wall to the front rim of the bowl). The Swiss Madison Sublime II in round compact configuration at Bathify falls in this range - well under the standard 28-30 inch depth of a typical elongated toilet. For the absolute minimum projection from a floor-mounted toilet, a tankless model like the Swiss Madison Viro reaches approximately 20-24 inches. For the most radical space saving, a wall-hung toilet projects only 14-18 inches from the wall (bowl only, with the tank hidden in the wall cavity). The key measurement is total projection - always verify the full "overall depth" or "total depth" spec on the product page, not just the bowl length, since the tank adds depth behind the mounting point. In US powder rooms, which are typically 36"-48" wide and 48"-60" deep, any toilet with a total projection under 27" is considered compact and appropriate. All Swiss Madison models at Bathify carry detailed dimension specifications on their product pages.
Q
What is the minimum bathroom size required for a toilet?
Per the 2024 International Plumbing Code (IPC), the minimum clearances for a toilet are: 21 inches of clear floor space in front of the toilet (from the front rim to any wall, door, or fixture), and 15 inches from the centerline of the toilet to any wall or fixture on each side (30 inches total width). This means the absolute minimum workable bathroom width for a toilet zone is 30 inches, and the minimum room depth must be the toilet's total projection plus 21 inches. For a compact toilet projecting 26 inches, that's 26 + 21 = 47 inches of minimum depth - about 4 feet. In practice, most powder rooms and half-baths in US homes measure 48"-60" deep, which accommodates compact toilets comfortably. A room under 44" deep becomes genuinely challenging for any floor-mounted toilet - wall-hung or tankless configurations may be the only code-compliant options in those extreme cases. Always verify local code, as some municipalities have adopted modified standards. If you're planning a new bathroom addition or major remodel, confirm clearance requirements with your local building department before finalizing the floor plan.
Q
Are round toilet bowls better than elongated in small bathrooms?
Round toilet bowls are better than elongated specifically when front clearance is tight - they project approximately 2 inches less than a standard elongated bowl. In a small bathroom where every inch matters, that 2-inch difference can be the margin between meeting the 21-inch IPC minimum front clearance and falling short. For a powder room or half-bath with 50-56 inches of total room depth, a round bowl often makes the space feel notably more functional and less cramped. The trade-off is comfort: round bowls provide less front-to-back seating surface, which most adults notice in daily use - particularly taller adults with longer legs. For a primary household bathroom used multiple times daily by adults, a round bowl is a meaningful comfort compromise. For a powder room or guest bath used briefly and intermittently, most people don't notice the difference. The compact elongated option - available on some Swiss Madison models - is a middle-ground worth considering when room depth allows: it retains the elongated oval shape for better adult comfort while reducing projection by about 1-1.5 inches versus a standard elongated. For a full analysis of this decision, see our elongated vs round toilet guide.
Q
How do I know if I have a 10-inch rough-in instead of 12 inches?
The rough-in measurement is the distance from your finished wall (not the baseboard - the actual wall surface) to the center of the floor drain, measured by finding the center of the floor bolt caps at the base of your existing toilet. Pry off the decorative bolt caps, find the floor bolts underneath, and measure from the finished wall to the exact center of one bolt. The center is usually directly at the midpoint of the bolt's shaft. If you measure 10-10.5 inches, you have a 10" rough-in. If you measure 12-12.5 inches, standard 12". If you measure 14-14.5 inches, you have a 14" rough-in (less common - primarily found in some pre-1950 New England homes). The 10-inch rough-in is most common in pre-1970 construction in the urban Northeast (New York, Boston, Philadelphia, Newark), Upper Midwest (Chicago, Detroit, Milwaukee), and some mid-Atlantic cities. If you're in an apartment building built before 1970 in any of these metros, there's a meaningful chance you have a 10" rough-in - measuring takes 2 minutes and saves you from an expensive return situation. For Bathify's 10" rough-in options, the Swiss Madison Concorde 10" and St. Tropez 10" are the recommended choices.
Q
Is a wall-hung toilet worth it in a small bathroom?
Yes - wall-hung toilets are the single most impactful space modification available in a small bathroom renovation, and they're worth the installation investment in most remodel contexts. By hiding the tank inside the wall, a wall-hung toilet reduces room projection to 14-18 inches (bowl only) versus 26-30 inches for a floor-mounted tanked toilet. That's 8-14 inches of recovered floor space - enough to meaningfully change how the room feels to move around in. The open floor below the bowl also creates an airy, floating visual that makes small bathrooms read as substantially larger in photographs and in person. The Swiss Madison Concorde wall-hung ($219.99 at Bathify) and Ivy wall-hung ($196.99) are the entry points - the bowl prices are competitive, but factor in the in-wall carrier system (typically $200-$400 separately) and professional installation ($600-$1,500 depending on your market and existing wall construction). In markets like New York, San Francisco, Seattle, and Boston where bathroom renovation adds significant home resale value, the total cost of a wall-hung installation ($1,000-$2,500 including carrier and labor) is typically recovered at sale. In markets with lower renovation ROI, the investment is harder to justify purely financially - but the daily quality-of-life improvement in a small bathroom is real and sustained.

Q
What style toilet looks best in a small modern bathroom?
In a small modern bathroom, the toilet style principles are: (1) skirted trapway - always, in a small room where the toilet sides are always visible; (2) one-piece construction - the seamless tank-to-bowl profile reads cleaner than a two-piece with its visible tank gasket line; (3) top-mounted button actuator - the modern alternative to a side handle, creates a cleaner tank profile; and (4) a bowl shape that matches the bathroom's design language - square/geometric for ultra-modern, curvilinear for transitional modern. The Swiss Madison Carre (square 1-piece at ~$370-$400 at Bathify) is the strongest design-forward compact toilet in the lineup for modern and contemporary small bathrooms - its geometric proportions look intentional rather than just space-saving. For small bathrooms with a maximalist or dramatic design (dark walls, patterned tile, statement fixtures), the Sublime II in glossy black is an effective design accent. For minimalist white-on-white bathrooms, any skirted one-piece in white disappears into the design and lets other elements lead. The key principle: in a small bathroom, the toilet is always visible, so it needs to look like a considered design choice rather than a default fixture.
