We tested and ranked the best bidet toilet seats available in 2026 - from the TOTO Washlet A2 at entry level to the fully automated S7A at the top of the range. Every pick is sold at Bathify with free shipping across the USA, and every ranking is based on real features, real prices, and real bathroom use cases - not affiliate bias.
The bidet toilet seat market in 2026 is, for American buyers, almost entirely a TOTO Washlet story. TOTO makes the best electronic bidet seats sold in the US, they're the seats that appear in the bathrooms of people who've actually used both budget and premium options and made a deliberate choice, and they're what we stock at Bathify. The ranking below covers six Washlet models - the full range from the A2 entry seat to the S7A top-of-line - with honest assessments of what each does well, what each omits, and who should buy each one.
A note on our methodology: these rankings are based on feature completeness at each price tier, the specific quality of the EWATER+ and PREMIST systems, heat and spray performance consistency, remote quality and usability, lid design, and Washlet+ compatibility (which determines how cleanly a seat integrates with a Washlet+-ready toilet). We've also weighed real buyer feedback on where each seat fails - which is where most reviews skip - so you go in knowing exactly what you're choosing between.
Every TOTO Washlet is available in elongated and round bowl configurations. Measure your existing toilet bowl before ordering - elongated bowls are roughly 18-19 inches front to back; round bowls are 16-17 inches. Installing an elongated seat on a round bowl is uncomfortable and unsafe. Most US toilets sold after 2000 are elongated, but older homes in cities like Chicago, Boston, and Philadelphia commonly have round bowls. Confirm the shape before purchasing - it's not something you want to discover after unboxing. All Washlet seats at Bathify ship free on orders over $50 to the continental US. Our Bidet vs. Toilet Paper guide explains why it's worth making the switch in the first place if you're still deciding.
Best bidet toilet seats of 2026 at a glance
🥇 Best Overall: TOTO Washlet S7A - automated lid, EWATER+, Washlet+ ready, 5 spray modes, remote with 4-user memory. The complete package.
🥈 Best Mid-Range: TOTO Washlet S7 - same core as the S7A minus the auto open/close lid. Save $100-$200 for nearly identical everyday performance.
🥉 Best Value: TOTO Washlet C5 - EWATER+, PREMIST, heated seat, 2-user remote, warm-air dryer. Covers 95% of what most people actually use, at ~$410.
Best Budget Premium: TOTO Washlet S2 - instantaneous heating, EWATER+, side-panel controls. The slimmest profile in the lineup. ~$340-$380.
Best Entry-Level: TOTO Washlet A2 / KC2 - basic rear and front wash, heated seat, soft-close. No EWATER+, no remote, but a solid first bidet at ~$280-$310.
Every seat in this ranking carries TOTO's core quality standard - the ceramics are better, the spray systems are more consistent, and the build tolerances are tighter than any other electronic bidet brand sold in the US. The ranking within the lineup is based on five criteria, weighted by how much they affect the daily-use experience:
| Criterion | Weight | What We Looked At |
|---|---|---|
| Water heating system | High | Instantaneous vs tank-based - affects whether warm water runs out mid-wash |
| EWATER+ & PREMIST | High | Electrolyzed water wand/bowl cleaning system - a genuine hygiene differentiator |
| Spray modes & control | High | Number of spray modes, remote vs arm panel, user memory profiles, oscillation |
| Lid technology | Medium | SoftClose, auto open/close, nightlight - quality-of-life factors in daily use |
| Washlet+ compatibility | Medium | Concealed cord/hose routing for Washlet+-ready toilets - affects visual integration |
Price-to-feature ratio determines ranking within tiers - a seat that costs $200 more should deliver meaningfully better performance or automation, not just a cosmetic upgrade. We've noted where the real-world performance difference between adjacent tiers is minimal, so you can decide whether stepping up justifies the spend for your specific situation.
The TOTO Washlet S7A is the best bidet toilet seat you can buy in 2026 for a primary bathroom, and it isn't close. The S7A adds one critical feature over the S7: an automated lid that opens and closes using sensor detection - when you walk toward the toilet, the lid lifts; when you walk away, it closes. This sounds like a novelty until you experience it in daily use, at which point it becomes the feature you miss most in every other bathroom you visit.
Beyond the auto lid, the S7A delivers TOTO's full feature stack: five spray settings (soft rear cleanse, rear cleanse, front cleanse, oscillating, pulsating), EWATER+ electrolyzed water that mists the wand before and after every use and mists the bowl after each flush, PREMIST that pre-wets the bowl before use to prevent waste adhesion, instantaneous water heating for unlimited warm water, a heated seat with variable temperature, warm-air dryer, automatic air deodorizer, nightlight, and a luxury illuminated touchbutton remote with 4-user memory storage. The contemporary lid sits flush with the toilet bowl - when installed on a compatible toilet, the S7A reads as an integrated appliance, not an add-on accessory.
The S7A is Washlet+-compatible, meaning it's designed to conceal its power cord and water supply hose inside the toilet body when installed on a Washlet+-ready TOTO toilet (Supreme II, Legato, Drake II Washlet+ models). This cord-concealment integration is the visual detail that separates a Washlet+ installation from a standard bidet seat retrofit - and it's only available on Washlet+-compatible seats like the S7A.
- Auto open/close lid - the best daily-use upgrade
- Complete EWATER+ bowl and wand self-cleaning
- Unlimited warm water - instantaneous heating, never cold mid-wash
- 4-user memory remote - ideal for households with different preferences
- Cleanest Washlet+ integration on any seat in the lineup
- Nightlight eliminates mid-night light switching
- The most expensive seat in the Washlet lineup - significant premium over S7
- Auto lid requires a nearby GFCI outlet; cord management visible on non-Washlet+ toilets
- Auto lid sensor can occasionally false-trigger in small bathrooms with high foot traffic nearby
The TOTO Washlet S7 delivers everything the S7A delivers except automatic lid operation. That's the complete difference between the two seats. The S7's lid is SoftClose - meaning it closes gently under its own hydraulic damper rather than slamming - but you lift and lower it manually. Every other feature is identical: EWATER+, PREMIST, instantaneous water heating, 5 spray settings, the illuminated 4-user memory remote, nightlight, warm air dryer, air deodorizer, and Washlet+ compatibility with concealed cord routing.
For households where auto lid isn't a priority - either because you already manually lower the lid habitually, or because the $100-$200 savings is more appealing than the hands-free automation - the S7 is the smarter purchase. The core wash performance is identical to the S7A. The EWATER+ system works the same. The remote is the same. The Washlet+ integration is the same. You're making one trade-off (hands-free lid) for a meaningful price reduction, and for many buyers, that's the right call.
Available in contemporary and classic lid styles at Bathify. The contemporary lid sits lower and flatter against the toilet bowl; the classic lid has a slightly higher profile. Both are Washlet+-compatible. Choose based on the profile of your toilet - the contemporary lid is the better visual match for modern toilets like the TOTO Supreme II or Legato; the classic lid works better with traditional profiles like the Drake II.
- Identical wash performance to S7A at lower cost
- Full EWATER+ - bowl and wand self-cleaning every use
- 4-user remote with full feature control
- Washlet+ compatible - cleanest possible cord concealment
- Available in contemporary and classic lid styles
- No auto open/close lid - only meaningful differentiator vs S7A
- Still the most expensive standalone bidet seat on this list after S7A
The TOTO Washlet C5 is the best value bidet seat in the entire Washlet lineup and the right answer for most American households upgrading from no bidet seat. At around $410 at Bathify, it includes EWATER+ (wand self-cleaning, not bowl misting - a distinction explained below), PREMIST, a heated SoftClose seat, adjustable warm water spray with 5 pressure settings, dual-action spray with oscillating option, warm-air dryer, air deodorizer, and a wireless remote with 2-user memory. This is not a budget product with cut corners - it's TOTO's deliberately positioned value seat, and it delivers the core Washlet experience at a price that's justifiable without requiring a primary-bathroom rationale.
The C5's wireless remote is a meaningful step up from the arm-panel controls on the A2 and KC2 entry seats - the remote can be wall-mounted next to the toilet, meaning you never have to reach to the side of the seat to adjust settings. The 2-user memory (vs 4 on the S7/S7A) covers most households without issue; only multi-generational homes or households with 3+ regular bathroom users will notice the limit.
What the C5 omits vs the S7: the bowl EWATER+ misting after each flush (the C5 has wand EWATER+ but not post-flush bowl misting), instantaneous water heating (the C5 uses a tank-based warm water system that can deplete over extended use - typically 90 to 120 seconds of warm water), and Washlet+ cord concealment. For most users, none of these omissions are dealbreakers. The bowl EWATER+ difference is a cleanliness enhancement, not a hygiene failure. The warm water tank is sufficient for standard use - it only becomes an issue for unusually extended sessions.
- Best value seat in the TOTO lineup - covers 95% of daily-use features
- Wireless remote with 2-user memory - better control than arm-panel seats
- EWATER+ wand self-cleaning included - a genuine hygiene upgrade
- PREMIST bowl pre-wetting - reduces cleaning frequency meaningfully
- Air deodorizer standard - not an add-on at this tier
- Tank-based warm water - can cool during extended sessions
- No bowl EWATER+ post-flush misting (wand only)
- No Washlet+ cord concealment - visible cord on most toilet installs
- 2-user remote memory vs 4 on S7/S7A
The C5 vs the S2 choice: The C5 has the wireless remote; the S2 has instantaneous water heating and a slimmer profile but uses arm-panel controls only. If you prefer remote control and don't mind the tank-based heating, take the C5. If you want instantaneous heating and don't mind reaching to the side to control, take the S2. The everyday wash quality is very similar between these two seats - the differentiators are control style and heating system, not spray power or cleanliness.
The TOTO Washlet S2 is the seat for buyers who want instantaneous water heating - unlimited warm water that never cools - without paying the S7-tier price for it. The S2's tankless design produces a 19% slimmer profile than tank-based seats like the C5, which is the visible difference when the seat is installed: it sits closer to the bowl and reads as more integrated. For bathrooms with a contemporary or minimalist aesthetic, the slim profile is worth noting.
The S2 includes EWATER+ for wand cleaning (same as the C5, not the full bowl-misting system of the S7 tier), PREMIST, a heated seat with 3 temperature settings, adjustable water temperature and pressure, front and rear wash, oscillating stream option, warm-air dryer, automatic air deodorizer, and nightlight. Controls are on an arm panel on the side of the seat - no wireless remote. For users who find side-panel controls intuitive, this is a non-issue. For users who prefer not to reach to the side while seated, it's a meaningful ergonomic limitation compared to the C5's wireless remote.
The S2 is also available at Bathify in both elongated and round bowl configurations, making it one of the few seats in the mid-range tier that cleanly fits round toilet bowls - relevant for older US home bathrooms in cities like Boston, Philadelphia, and New York where round bowl toilets are more common in pre-1990 construction.
- Instantaneous water heating - unlimited warm water at all times
- Slimmest profile at this price tier - 19% thinner than tank-based seats
- Nightlight included - not standard at this price point
- PREMIST + EWATER+ wand cleaning
- Available round and elongated - fits older bathroom bowl shapes
- Arm-panel controls only - less convenient than the C5's wireless remote
- No Washlet+ compatibility - cord visible on all installs
- No bowl EWATER+ misting after flush
- Only 3 seat temperature settings vs 5 on S7/S7A
The TOTO Washlet A2 and KC2 are the entry points to the Washlet lineup - and they're still meaningfully better than every non-TOTO electronic bidet seat at a similar price. Both include a heated SoftClose seat, rear and front wash, adjustable temperature and pressure settings, warm-air dryer, and arm-panel controls. They do not include EWATER+ (no electrolyzed water wand cleaning), no wireless remote, no air deodorizer, and no nightlight. The spray wand self-cleans mechanically, not with EWATER+ - which is functional but not equivalent to the electrolyzed water system.
The practical difference between the A2 and the KC2 is minor: the KC2 is slightly more compact and is TOTO's most recent entry-level redesign with a lower back profile. Both are appropriate for first-time bidet buyers, guest bathrooms, secondary bathrooms in multi-toilet homes, and anyone who wants to experience the Washlet system without committing to the C5+ price tier. For primary bathrooms where the seat will be used daily by multiple adults, we recommend stepping up to at least the C5 - the EWATER+ wand cleaning and wireless remote make a noticeable quality-of-life difference over 12-24 months of daily use.
The A2 is available at Bathify in elongated configuration. The KC2 is available in both elongated and round at Bathify, making it the entry-level option for round bowl toilet owners.
The TOTO Washlet spec sheet uses terminology that most buying guides never explain. Here's what the key terms actually mean in daily use:
TOTO's proprietary system that generates electrolyzed water - water treated with a low electrical charge to produce a safe, mildly antimicrobial compound. EWATER+ appears in two forms in the lineup: wand EWATER+ (used on C5, S2, S7, S7A) cleans the spray wand before and after each use; bowl EWATER+ (S7, S7A only) also mists the toilet bowl after each flush, reducing the frequency of bowl cleaning. EWATER+ is a genuine differentiator - it's not a marketing term. Wands on EWATER+-equipped seats stay cleaner longer and require less manual cleaning, particularly in hard-water households.
Before each use, PREMIST uses the incoming water supply to mist the toilet bowl surface. The wet bowl surface reduces waste adhesion - the main reason bidet toilet owners clean their bowls less frequently than non-bidet households. PREMIST is available on all seats C5 and above in the TOTO lineup. It is not available on the A2 or KC2.
Tank-based warm water (A2, KC2, C5): the seat heats a reservoir of water that depletes during extended use - typically 90-120 seconds before the water cools. For the majority of users, this reservoir is sufficient. Instantaneous heating (S2, S7, S7A): the water is heated on demand as it flows through the seat, providing unlimited warm water for any length of session. The instantaneous system also allows a slimmer seat profile (no tank bulge). If warm water running cool mid-wash is a dealbreaker for you, choose a seat with instantaneous heating.
Washlet+ is TOTO's cord-concealment system. A Washlet+-compatible seat has its power cord and water supply hose routed to exit the seat at a specific location that matches a channel built into Washlet+-compatible TOTO toilets (Supreme II, Legato, Drake II Washlet+ editions, and others). On a Washlet+ toilet, the cord and hose disappear into the toilet body - completely hidden from view. On a non-Washlet+ toilet, the cord runs visibly to a nearby outlet. Only the S7 and S7A are Washlet+-compatible in the current lineup. If you own or are buying a Washlet+-ready toilet, you must buy the S7 or S7A to get the concealed-cord integration - no other Washlet seat achieves this.
A proximity sensor in the seat detects when a user approaches and raises the lid automatically; when the user walks away, the lid closes. This requires no button press or remote activation. The feature is exclusive to the S7A in the current lineup. It's a luxury convenience feature, not a hygiene feature - but it's the detail that makes the daily experience feel most like an integrated appliance rather than an accessory.

You're outfitting a primary bathroom and want the best available without limitation. You own or are buying a Washlet+-compatible TOTO toilet and want the clean cord-concealed integration. You have a household where hands-free automation (auto lid, PREMIST, EWATER+ bowl misting) meaningfully reduces cleaning time. Budget is $1,300-$1,500 for the seat alone.
You want S7A performance without paying the auto-lid premium. You use a Washlet+-compatible toilet and want concealed cord routing. You prefer the 4-user remote memory over the C5's 2-user limit. Budget is $1,100-$1,300.
You want a full-featured bidet seat for any bathroom without the S7-tier price. You value wireless remote control over arm-panel controls. EWATER+ wand cleaning and PREMIST cover your hygiene priorities. Budget is $400-$500. This is our most recommended seat for first-time Washlet buyers who've committed to the upgrade and want to do it right.
Unlimited warm water (instantaneous heating) is a priority and you don't want to pay S7 pricing for it. You prefer a slim, low-profile seat design. You're comfortable with arm-panel controls. Budget is $330-$400.
You're purchasing a first bidet seat and want to start the Washlet experience at entry price. You're equipping a guest bathroom or secondary bathroom where daily advanced features aren't needed. Budget is $270-$320. Or: you have a round bowl toilet and need a confirmed-compatible TOTO seat (KC2 comes in round).
Every TOTO Washlet seat is designed for DIY installation - no plumber required. The typical install takes 20-30 minutes with basic tools. Before ordering, confirm these three things:
| Requirement | What to Check | Why It Matters |
|---|---|---|
| Bowl shape | Elongated (~18-19" front to back) or round (~16-17") | Order the matching seat shape - wrong shape is uncomfortable and unsafe |
| GFCI outlet | Must be within 4 feet of the toilet, on a dedicated 15A circuit | All electronic bidet seats require a nearby grounded outlet - no extension cords |
| Washlet+ toilet? | Check if your toilet is Washlet+-compatible (TOTO models: Supreme II, Legato, Drake II Washlet+, etc.) | Only purchase S7 or S7A if you want cord-concealed Washlet+ integration |
| Water supply | Standard ⅜" compression fitting under the toilet - universal compatibility | All Washlet seats include a T-valve; no extra plumbing parts typically needed |
The C5 for most people. The S7A for primary bathrooms with no ceiling. The S7 for the smart middle ground.
The best bidet toilet seat of 2026 for the majority of American households is the TOTO Washlet C5 - it delivers EWATER+, PREMIST, a wireless remote with user memory, heated seat, warm-air dryer, and air deodorizer at around $410. The step-down to the A2 or KC2 saves $120-$130 but loses EWATER+, the remote, and the air deodorizer - three features that meaningfully affect daily experience over months of use. The step-up to the S7 or S7A adds bowl EWATER+ misting, instantaneous heating, Washlet+ cord concealment, and 4-user memory - worth it if those specific features matter to your primary bathroom and your budget allows.
If you have a Washlet+-compatible toilet and want the cleanest possible installation, the S7 is the value choice and the S7A is the complete package. If you're buying your first bidet seat, starting at the C5 means you'll be satisfied enough to never regret the purchase - and that's the metric that matters most.
