Elegant Tradition, Everyday Comfort

The TOTO Guinevere WASHLET+ One-Piece Toilet blends traditional styling with modern luxury. Its sculpted tank, decorative detailing, and graceful curves make a classic design statement in any bathroom. The fully skirted base conceals the trapway for a seamless silhouette that’s easy to clean and visually timeless.

This model delivers powerful performance with a 1.28 GPF TORNADO FLUSH® system that uses dual-nozzle flushing to keep the bowl spotless with less water. The bowl is finished with CEFIONTECT®, TOTO’s ultra-smooth ceramic glaze that resists staining and waste buildup.

  • The Guinevere’s WASHLET+ integration features the WASHLET S2 bidet seat, fully connected without any visible hoses or power cords. This smart seat offers essential comfort upgrades like endless warm water cleansing, a heated seat, warm air dryer, and built-in deodorizer.

    All functions are controlled by a side-arm panel that’s fixed to the seat itself. This intuitive interface gives users full access to cleansing and comfort settings without needing a remote or wireless controls, making it easy to operate with zero setup required.

  • With each use, the system activates PREMIST®, which lightly mists the bowl before use to help prevent residue from sticking. Once cleansing is complete, EWATER+® rinses the wand inside and out using electrolyzed water, keeping the nozzle clean and sanitary between uses.

    These features work together with the powerful flush and CEFIONTECT® finish to minimize buildup in and around the bowl. Since the base is fully skirted, it also eliminates hard-to-reach areas around the trapway for easier exterior maintenance.

Simple, Intuitive Control

The S2 seat uses a side control panel for all functions, including water pressure, spray type, nozzle position, seat temperature, and air drying. There’s no learning curve—just direct access to daily comfort features with clearly marked buttons right on the seat.

Because the S2 doesn’t rely on a wireless remote or memory presets, it’s a great option for households that prefer simplicity and reliability. Every feature is readily accessible, and operation remains consistent without batteries or recharging.

Classic Form. Seamless Function.

The Guinevere toilet offers flexible installation with models available in 10", 12", or 14" rough-in sizes, making it easy to accommodate a range of renovation and remodel scenarios. Its one-piece design offers a sleek appearance and prevents leaks between tank and bowl.

With its Universal Height seating and ADA-compliant design, the Guinevere offers both beauty and accessibility. It’s a refined choice for homeowners seeking classical aesthetics paired with smart comfort and proven TOTO reliability.

TOTO Guinevere Washlet+ S2 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!
