Sleek Style Meets Smart Innovation

The TOTO Aquia IV Washlet+ S7A One-Piece Toilet delivers a modern, minimalist look with advanced performance to match. Its fully skirted design and seamless one-piece construction offer easy maintenance and a refined profile that suits any contemporary bathroom.

This model includes TOTO’s Washlet+ integration, which conceals the power cord and water supply line for a built-in look. With an elongated bowl, Universal Height seat, and quiet dual flush operation, it combines comfort, hygiene, and high-efficiency performance into a single compact form.

  • At the heart of this model is the advanced Washlet S7A, which transforms the toilet into a fully featured bidet system. The S7A includes a dual-action spray with oscillating and pulsating modes, instant and unlimited warm water, and a gentle aerated stream for optimal cleansing. PREMIST® mists the bowl before each use, and EWATER+ cleans the wand and bowl automatically after every session.

    A standout feature is its auto open/close lid with proximity sensor, delivering a hands-free, high-end user experience. It’s also compatible with TOTO’s optional auto flush kit, allowing for a fully touchless operation when installed. With four user memory presets and full control via a sleek pearl-white remote, the Washlet S7A offers one of the most luxurious bidet experiences available.

  • The Washlet S7A comes with a multifunctional remote control in a clean, block-style design. It allows you to adjust every aspect of your bidet experience—from spray mode and temperature to dryer heat and deodorizer activation. Its slim profile and wall-mountable design help keep your bathroom clutter-free.

    In addition to core features, the remote gives access to four user presets, making it easy to switch between personalized settings. The intuitive layout ensures a smooth, luxurious experience for every user, whether it’s your first time or your daily routine.

Personalized Comfort, Your Way

The Washlet S7A’s remote is designed for those who want maximum comfort with minimal effort. Whether you’re adjusting spray strength or switching between front and rear cleansing, every function is right where you need it. The remote also controls the heated seat, warm air dryer, deodorizer, and the auto open/close lid.

Best of all, it’s ready for TOTO’s optional auto flush system, enabling a fully automated bathroom experience when installed. With four programmable user presets and intuitive controls, this remote ensures a personalized and effortless hygiene upgrade for every member of the household.

Designed for Comfort, Built for Versatility

The Aquia IV Washlet+ S7A One-Piece Toilet is built for both visual harmony and high-efficiency flushing. Its skirted, one-piece design is sleek and easy to clean, while the elongated bowl and Universal Height seat offer ergonomic support for users of all ages. The concealed trapway and hidden Washlet connections help maintain the minimalist design.

TOTO’s DYNAMAX TORNADO FLUSH® system uses only 1.28 or 0.9 gallons per flush while maintaining powerful performance. Combined with CEFIONTECT® ceramic glaze, it keeps the bowl cleaner longer with less need for scrubbing—making it as efficient as it is beautiful.

Aquia IV Washlet+ S7A Installation

TOTO Washlet+ systems install like a classic toilet. There are only a few additional factors to consider:

  • Check the size of the rough-in in your bathroom (the distance from the finished wall behind your toilet to the center of the toilet drainpipe or flange). All Washlet+ models are designed for a 12" rough-in, but if you have another size, most models have adapters available.
  • Access to a standard GFCI electrical outlet is required for your Washlet to function.
  • Your Washlet will utilize the same water connection that fills the toilet's tank via an included T-valve.
  • See the video guide below for installation of your new Washlet+ system!

Fantastic Bidet!

I could not be more pleased with the purchase of this product. Beginning with the great communication with Eric while contemplating on which bidet was best for me, his no-pressure salesmanship and courteous demeanor down to the beautiful bidet that was delivered (very quickly, I might add!). The bidet is amazing! Very high quality and better than I had imagined it being. I highly recommend both buying this bidet as well as ordering through House of Bidets. They are top notch!
