Elegant Tradition, Everyday Comfort

The TOTO Guinevere WASHLET+ One-Piece Toilet brings classic, sculpted beauty into the modern era. With its ornate tank design, skirted base, and flowing lines, the Guinevere stands out as a refined centerpiece in any traditional or transitional bathroom. The one-piece construction enhances its clean profile, removing seams and simplifying maintenance.

This toilet features a powerful yet quiet 1.28 GPF TORNADO FLUSH® system that uses two nozzles to create a centrifugal rinse, leaving the bowl cleaner with each flush. Paired with TOTO’s CEFIONTECT® ceramic glaze, it minimizes waste adhesion while maximizing elegance and efficiency.

Classic Styling, Modern Features

The WASHLET+ S5 bidet seat integrates seamlessly into the toilet, eliminating visible cords and hoses for a polished look. It features endless warm water cleansing, a heated seat, a warm air dryer, and a deodorizer, all controlled from a modern wireless remote.

This remote gives users full access to every setting, from nozzle position and spray pressure to seat temperature and air drying. The S5 also includes four user memory presets, making it easy for everyone in the household to enjoy their ideal experience with just the press of a button.
Every feature of the Guinevere WASHLET+ system supports easier maintenance and a more hygienic daily routine. PREMIST® begins the process by lightly spraying the bowl before each use to help prevent sticking. Afterward, EWATER+® cleans the wand using electrolyzed water, keeping the nozzle fresh and sanitary.

The CEFIONTECT® finish further supports this self-cleaning approach by resisting stains and preventing residue buildup. And with a fully skirted base, the outside of the toilet is just as easy to keep clean as the bowl itself.

Simple, Intuitive Control

With the S5, every function of your WASHLET is at your fingertips. The remote features an intuitive layout with backlit controls for nighttime use and allows for easy toggling between front and rear wash modes, oscillation, pulsation, drying, and deodorizing.

You can store four distinct user profiles, letting each person recall their exact settings instantly. This convenience, combined with a sleek wall-mounted holder, makes the S5 ideal for households that want a luxurious, customized cleansing experience without clutter or complexity.

Sculpted Sophistication, Seamless Installation

The Guinevere is available in 10", 12", and 14" rough-in options, making it suitable for a wide range of remodel and new-build installations without the need for adapters. The one-piece construction streamlines the silhouette and prevents leaks between tank and bowl.

At Universal Height, this toilet offers comfort and accessibility for users of all ages and meets ADA compliance guidelines when installed properly. Its timeless form paired with the innovation of the S5 seat makes the Guinevere a perfect blend of heritage style and hygiene-focused performance.

TOTO Guinevere Washlet+ S5 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.
