Is the TOTO Aimes WASHLET+ S7A Worth It?
Yes — and I’ll say that without much hesitation.
The Aimes WASHLET+ S7A isn’t just a bidet seat attached to a nice toilet.
It’s a fully integrated system where the toilet and bidet seat were designed together from the ground up, and that intentional pairing shows in every detail — from the completely hidden power cord to the lid that sits perfectly flush with the bowl.
If you’ve been researching the highest rated bidet toilets, you’ve probably noticed the Aimes + S7A system keeps appearing in the same conversations as fully integrated units that cost significantly more.
That’s because this WASHLET+ approach delivers roughly 90% of the integrated experience at a considerably lower price than something like the Neorest integrated smart toilet lineup.
For most buyers who want the look and feel of a luxury bidet toilet without paying Neorest prices, this is the most practical path to get there.
Design and Build Quality
The Aimes toilet is a one-piece, skirted design — meaning the tank, bowl, and base are all one continuous unit with no visible gaps or seams where bacteria can hide.
The skirted trapway is one of my favorite things about this toilet.
On a standard two-piece toilet, cleaning behind and around the trapway is awkward and easy to skip.
With the Aimes, you wipe a smooth, continuous surface that takes about thirty seconds.
CEFIONTECT® ceramic glaze coats the entire porcelain bowl, creating an ion-barrier that repels waste particles so well that the bowl essentially self-polishes with each flush.
Pair that with TORNADO FLUSH® — a dual-nozzle centrifugal rinsing system that creates a powerful cyclonic wash without a visible rim channel — and you’ve got a toilet that stays visibly cleaner between deep cleans than anything I’ve used before.
The S7A bidet seat sits at just 4.1 inches in rear height, which is incredibly slim for a seat with this many features.
The contemporary lid design sits perfectly flush with the toilet bowl, creating a look that genuinely rivals a fully integrated unit when you step back and look at the complete system.
Universal Height places the seat at just over 17 inches — ergonomically comfortable for most adults and ADA compliant when used with the included auto flush kit.
Cleaning Performance
The S7A’s hygiene system is the most comprehensive you’ll find in a bidet seat, and using it daily makes this very clear.
PREMIST® activates automatically before you sit down, coating the entire interior of the bowl with a fine mist of water so waste slides off cleanly rather than sticking to the porcelain.
After each use, EWATER+® kicks in — electrolyzing tap water into a mild sterilizing agent that automatically rinses the spray wand inside and out, then mists the toilet bowl.
Together, these two systems mean your toilet bowl and bidet wand are being actively cleaned after every single use — not just when you remember to clean them.
For anyone who’s read our guide on bidet toilet seat hygiene technology, you’ll know that EWATER+ bowl cleaning is a feature exclusive to the S7 and S7A — the S5 gets EWATER+ wand cleaning but not the bowl rinse.
The spray itself offers five settings: rear, rear soft, front, wide front, and oscillating/pulsating modes.
Water temperature is adjustable between 86°F and 104°F across five levels, and spray pressure is similarly customizable.
The AIR-IN WONDER WAVE technology infuses tiny air bubbles into each water droplet, creating a softer but surprisingly effective spray that feels gentler than its cleaning strength would suggest.
Comfort Features
The heated seat maintains a surface temperature between 82°F and 97°F — warm enough to feel genuinely luxurious, especially on cold mornings.
The auto energy saver mode reduces seat temperature when the seat has been inactive for a set period, which meaningfully reduces electricity consumption without sacrificing comfort when you actually need it.
The warm air dryer operates at temperatures between 95°F and 140°F across five adjustable levels, with airflow volume of 8.83 cubic feet per minute — more than adequate for effective drying when you give it the time it needs.
The automatic deodorizer uses a carbon air filter rather than synthetic fragrances, eliminating odors rather than just masking them.
The night light on the S7A is notably better than what you’d find on most bidet seats — it illuminates both the side of the unit and the interior of the bowl, which makes nighttime trips to the bathroom genuinely comfortable without needing to turn on a bright overhead light.
If you want to compare how this comfort package stacks up against other premium seats, our bidets with warm water and dryer guide gives a helpful overview of what’s available at different price points.
Controls and Installation
The illuminated touch-button remote uses a sliding action to reveal functions, storing personalized settings for up to four users.
Each of the four preset slots saves your preferred spray mode, water temperature, spray pressure, nozzle position, seat temperature, and dryer temperature — so every member of your household gets their exact settings at the touch of one button.
The auto open/close lid deserves its own mention.
A motion sensor detects when you approach and raises the lid automatically, then closes it roughly a minute after you’ve departed.
The sensitivity and timing are adjustable via the remote, so it won’t trigger when someone simply walks past the bathroom door.
Installation of the toilet itself requires a plumber for most buyers — you’re replacing a full toilet, which involves disconnecting the water supply, removing the old fixture, and properly setting the new one.
The bidet seat component follows standard WASHLET installation once the toilet is in place.
The WASHLET+ connection is the key feature here — the toilet has a built-in channel in the bowl surface that routes both the power cord and water supply line internally, so nothing is visible from the outside.
You’ll need a GFCI outlet within about four feet of the toilet’s rear.
The auto flush kit is included in the MW6264736CEFGA model and connects to the toilet’s sensor to flush automatically when you stand — genuinely hands-free from lid open to flush to lid close.
For buyers comparing this to a standalone seat on your existing toilet, our guide to bidets for existing toilets is worth reading to understand the practical differences.
Who Is the TOTO Aimes WASHLET+ S7A Best For?
This system is built for buyers who want the look, feel, and performance of a luxury integrated bidet toilet — but without spending Neorest money.
If you’re remodeling a primary bathroom and you want a clean, cohesive aesthetic with no visible cords or hoses, no mismatched toilet-and-seat combos, and no compromises on hygiene technology, the Aimes S7A is the most practical way to get there.
It’s also an excellent choice for multi-person households where the four-user preset system eliminates the need for anyone to adjust settings manually.
If you have mobility challenges or are aging in place, the ADA compliance, auto-open lid, auto flush, and hands-free operation make this genuinely life-improving — not just convenient.
If you’re comparing this to the TOTO S7A seat alone on a different toilet, read our TOTO S7 comparison to understand what the WASHLET+ toilet integration actually adds beyond the seat’s standalone performance.
Buyers on a tighter budget who still want the TOTO experience might want to consider the S5 or S7 seat on their existing toilet before committing to a full toilet replacement.
FAQ
Is the TOTO Aimes being discontinued?
No. The TOTO Aimes is a current, actively sold WASHLET+ toilet in TOTO’s lineup as of this writing.
It pairs with the current-generation S2, S5, S7, and S7A bidet seats.
The version reviewed here — the MW6264736CEFGA#01 with the S7A and auto flush — is TOTO’s flagship Aimes configuration.
Will the Aimes fit a round toilet rough-in?
The Aimes toilet uses a standard 12″ rough-in by default.
Optional adapter kits (TSU03W.10R for 10″ and TSU03W.14R for 14″) are available from TOTO and sold separately.
The bowl itself is elongated only — if your current toilet footprint is round, the Aimes will have a different visual profile in your space, so measure carefully before purchasing.
What does EWATER+ actually do on the S7A — and how is it different from the S5?
EWATER+ electrolyzes tap water to create a mild sterilizing agent.
On the S7A (and S7), EWATER+ cleans both the spray wand and the toilet bowl — before and after each use.
On the S5, EWATER+ cleans the wand only — not the bowl.
PREMIST® (which both seats have) pre-wets the bowl before you sit, which prevents waste from sticking to the porcelain.
The bowl EWATER+ rinse on the S7A goes one step further by actively disinfecting the bowl surface after each use — which is why the S7 and S7A keep the bowl noticeably cleaner between scrubbing sessions.
You can compare these two models side-by-side in our TOTO S5 vs S7A breakdown.
How does the TOTO Aimes WASHLET+ S7A compare to the TOTO Neorest?
The Neorest line — particularly the Neorest RS, AS, and NX series — are fully integrated bidet toilets where the bidet technology is built directly into the toilet unit itself.
The Aimes WASHLET+ S7A is a toilet paired with a bidet seat — a very well-integrated pair, but technically two components.
The Neorest line offers ACTILIGHT® UV deodorization (in higher models) and a completely seamless lid-to-bowl profile.
The Aimes S7A gets you remarkably close to the Neorest experience — EWATER+ bowl cleaning, auto open/close lid, auto flush, PREMIST, four user presets — at a meaningfully lower price point.
For buyers weighing both options, our best toilets with bidet guide covers exactly where the WASHLET+ approach sits relative to fully integrated Neorest units.
Conclusion
The TOTO Aimes WASHLET+ S7A is one of the most thoughtful bathroom upgrades you can make.
The combination of TORNADO FLUSH, CEFIONTECT glaze, PREMIST, EWATER+ bowl cleaning, auto open/close lid, and four-user presets covers every dimension of bathroom hygiene and comfort — and the seamlessly integrated WASHLET+ connection means it looks as good as it performs.
It’s not a small purchase, and it does require professional installation for the toilet itself.
But for buyers building or remodeling a primary bathroom who want the cleanest, most comfortable, most hands-free toilet experience available below Neorest prices, this system delivers exactly that.
