Classic Form. Modern Features.

The Supreme II WASHLET+ One‑Piece Toilet offers a refined silhouette anchored in timeless design and smart technology. With its one‑piece construction and low‑profile tank, the unit delivers a streamlined look while maintaining robust performance. The exposed trapway underlines its non‑skirted aesthetic, giving the piece a classic presence that blends easily into both modern and traditional bathrooms.

Beneath the styling lies the TOTO Tornado Flush® system, delivering powerful performance at 1.28 gallons per flush. Coupled with TOTO’s CEFIONTECT® ceramic glaze, which prevents residue from adhering to the bowl, the Supreme II is engineered to stay cleaner longer with less effort.

Timeless Styling. Smart Customization.

You can pair the Supreme II with either the WASHLET S2 or WASHLET S5 bidet seat—both fully integrated into the WASHLET+ design to conceal hoses and power cords for a seamless finish. The S2 model offers intuitive side‑arm controls mounted to the seat itself for straightforward operation. No remote, no battery hassles—just direct button access to wash modes, seat heating, and drying features.

For households seeking full customization, the S5 model includes a sleek wireless remote with up to four user memory presets. That means multiple users can save preferred spray pressure, nozzle position, water temperature, and seat warmth for rapid recall. Whether you prefer tactile simplicity or full personalization, the Supreme II accommodates both.
From the moment you sit down, the Supreme II system works to provide a cleaner experience. TOTO’s PREMIST® feature sprays the bowl before each use to minimize residue, and afterward, the EWATER+® system automatically rinses the wand inside and out using electrolyzed water—keeping components fresh with no extra effort.

Because the unit is one‑piece and low‑profile, there are fewer seams and crevices around the tank and bowl where dirt and dust can accumulate. Paired with the non‑skirted trapway, cleaning remains straightforward and efficient from top to base.

Cleansing Comfort Made Easy

With the S2 version, the side‑panel control gives you immediate access to essential features: adjust spray type, water temperature, seat temperature, nozzle position, and air drying—all through clearly labeled buttons on the seat. This layout suits users who prefer simplicity and reliability in everyday use.

If you choose the S5, every function comes to life via a wireless remote. Adjust spray style, use oscillating and pulsating modes, change air dryer strength, set the night‑light brightness, and recall up to four user presets. The remote can be mounted on the wall or used handheld—giving you freedom and full customization at your fingertips.

Classic Aesthetic, Modern Comfort

The Supreme II supports a standard 12″ rough‑in, making it suitable for most U.S. bathroom installations and simplifying replacements. Its one‑piece construction reduces leak points and simplifies installation overall, while the exposed trapway design maintains traditional character.

Designed at Universal Height, the Supreme II also offers comfortable access for users of all ages and meets ADA height guidelines when installed correctly. With powerful performance, smart bidet integration, and a classic form, it’s a premium choice for any bathroom upgrade.

TOTO Supreme II Washlet+ 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.
