Key Features
Advanced Personal Cleansing
Experience a spa-like cleanse with gentle aerated warm water sprays for both front and rear washing, featuring adjustable pressure along with oscillating and pulsating functions. Customizable temperature settings for both the water and heated seat allow users to tailor comfort to their preferences, while the integrated warm air dryer provides a complete cleansing routine without the need for toilet paper.
EWATER+® and PREMIST® Technology
TOTO technologies help reduce buildup, minimize maintenance, and keep the toilet cleaner with less reliance on harsh chemicals. PREMIST® automatically sprays the toilet bowl with a fine mist of water before each use, helping prevent waste from sticking to the surface. EWATER+® uses electrolyzed water to automatically clean the spray wand and bowl, reducing the need for harsh chemicals while maintaining a higher level of hygiene.
Personalized Remote Control & User Memory
The multifunction remote control allows users to easily adjust spray settings, temperature, and comfort features with intuitive precision. Personalized memory settings store preferred configurations for up to four users, making daily routines more convenient for shared households. Designed for both simplicity and customization, the control system enhances the smart functionality of the entire toilet experience.
Touchless Convenience & Self-Cleaning Hygiene
Enjoy a cleaner, more convenient bathroom experience with touchless and self-cleaning features. The auto open and close lid responds to user presence for hands-free operation, while the spray wand automatically cleans itself inside and out before and after every use to help maintain optimal hygiene. The Washlet is also compatible with TOTO's optional auto-flush system*, allowing the toilet to flush automatically after use.
*NOTE: Auto-flush system and compatible hardware are sold separately.

Performance: 5/5 
The S7A's performance is absolutely perfect and built for maximum ease. The instantaneous heating means you get an endless, powerful stream of warm water—you'll never run out, guaranteed. The EWATER+ system is ramped up to sanitize both the wand and the entire toilet bowl proactively, drastically cutting down on how often you have to clean manually. The warm air dryer is seriously effective, too. Plus, the subtle in-bowl night light and the enhanced, seamless-look seat profile are just fantastic little touches that make a huge difference.
User Experience: 5/5
The user experience is straight-up amazing, defined by effortless luxury. The Auto Open/Close Lid (it just senses when you walk up!) and the Auto Flush compatibility (requires a separate kit) make this setup almost entirely hands-off, which is the single best reason for upgrading to this model. If you have an older Toto toilet, you will want to check compatibility with your toilet model. The S7A features the absolute slimmest seat design TOTO has ever made, giving it a sleek, integrated look. Control is handled via a gorgeous, wall-mounted remote, which keeps the practical four user memory settings introduced in the S5, allowing complete customization for the whole family.
Quality: 5/5
As TOTO's flagship product, the S7A shows off TOTO's best engineering and material quality. The construction is incredibly durable, and the ultra-slim design is achieved without giving up stability or functionality. The seat features TOTO's specialized CLEAN RESIN coating to actively fight dirt buildup. Every component is designed for long-term reliability and market-leading aesthetics, confirming its perfect score in quality.
Value: 5/5
Yes, the S7A is the most expensive bidet seat TOTO offers, but its value is genuinely unmatched. The combination of features—the unique Auto Open/Close Lid, Auto Flush capability, and the full EWATER+ system—aren't found together in a single lower-tier model. For the user seeking the complete, future-proof, touchless experience and the slimmest design on the market, the premium price is totally worth it, making it a brilliant long-term investment in superior hygiene and convenience.
Final Verdict
Honestly, the TOTO S7A Washlet isn't just a gadget—it's the ultimate bathroom glow-up. It takes the solid foundation of the S5—tankless heating, EWATER+, and user presets—and adds the crucial Auto Open/Close Lid and Auto Flush compatibility. These features cement the S7A's status as the top-tier, undisputed market leader. If you want the absolute pinnacle of cleanliness, comfort, and hands-free convenience, the S7A is unequivocally the best luxury bidet seat available and fully deserves its perfect rating.
Since 1917, TOTO has been a global leader in bathroom innovation, known for superior quality, comfort, and design.

TOTO Washlet S7A FAQ
Can I install the TOTO S7A Washlet myself, or should I hire a professional?
The S7A bidet seat can often be installed by homeowners with basic DIY plumbing skills. To install the unit, remove your existing toilet seat, attach the included mounting plate, connect the Washlet to your toilet's cold water supply, and plug it into a nearby grounded 120V GFCI electrical outlet. If your bathroom does not already have an outlet near the toilet, you'll need to have one installed by a qualified electrician.
Will the S7A bidet seat from TOTO fit my existing toilet?
The S7A Washlet is designed to fit most standard elongated toilets, but compatibility depends on your toilet's shape, mounting hole spacing, and available space behind the bowl. Checking your toilet's dimensions before purchasing is the best way to ensure a proper fit.
How does the automatic open and close lid work on the S7A bidet seat?
The TOTO Washlet S7A features an automatic open and close lid that uses a built-in sensor to detect when someone approaches or leaves the toilet. The lid opens as you approach and closes automatically after use, reducing the need to touch the toilet and helping minimize the spread of germs. The feature can also be adjusted or disabled using the included remote control to suit your personal preferences.
What makes TOTO's Washlet S7A different from other electronic bidet seats?
The TOTO Washlet S7A combines advanced hygiene technologies with premium convenience features in an ultra-slim design. In addition to instant warm water, a heated seat, warm air dryer, deodorizer, and customizable cleansing options, it includes an automatic open and close lid, EWATER+®, PREMIST®, a night light, and more. These features work together to provide a more hygienic, personalized, and hands-free bathroom experience than many standard electronic bidet seats.
How long does it take to install the S7A smart bidet seat?
Most installations take between 30 minutes and one hour when the bathroom already has a compatible elongated toilet and a nearby electrical outlet. The S7A installation process includes removing the existing toilet seat, installing the mounting bracket, connecting the water supply, and plugging in the unit. Installation time may be longer if electrical work is being added.
