Effortless Clean, Seamless Style

The TOTO Nexus WASHLET+ One-Piece Toilet combines clean, minimalist lines with high-efficiency performance. Its fully skirted base and one-piece construction offer a smooth, uninterrupted profile that simplifies cleaning and gives the bathroom a refined, modern appearance. With a design that draws minimal attention to plumbing, it pairs effortlessly with both understated and luxury spaces.

Though simple in appearance, the Nexus packs powerful flushing performance. TOTO’s 1.28 GPF TORNADO FLUSH® system uses dual nozzles to generate a centrifugal, rinsing action that thoroughly cleans the bowl with every flush. The surface is coated in CEFIONTECT®, an advanced ceramic glaze that helps prevent residue from sticking.

Sleek Integration, Straightforward Control

The integrated WASHLET S2 bidet seat adds daily comfort and hygiene with continuous warm water cleansing, a heated seat, warm air drying, and automatic deodorizer. All water and power connections are hidden within the unit, preserving the sleek design aesthetic of the WASHLET+ system.

Instead of a remote, the S2 features a side-arm control panel mounted to the seat itself. This panel offers clear, tactile access to all bidet functions without the need for pairing or programming. It’s a dependable choice for users who prefer intuitive, physical controls over wireless remotes.
With each use, the Nexus WASHLET+ system initiates automatic hygiene features to keep the unit cleaner for longer. PREMIST® lightly coats the bowl before use, helping waste rinse away more easily. After cleansing, EWATER+® sanitizes the bidet wand both inside and out using electrolyzed water, minimizing the need for manual maintenance.

Combined with the smooth, skirted exterior and stain-resistant CEFIONTECT® glaze, the Nexus reduces the frequency and effort of cleaning both inside and around the toilet. These built-in features create a low-maintenance experience without compromising on cleanliness or comfort.

Intuitive Washlet Controls

The S2 control panel offers users complete control of their experience from the right side of the seat. From here, you can adjust the water temperature, spray type, pressure, nozzle position, and activate drying and deodorizing functions—all without needing to look for a remote or charge a battery.

This fixed, always-accessible panel ensures consistent operation for every user. It's especially well-suited for those who want easy access to bidet functions without the learning curve or complexity of remote-controlled models.

Sleek, Skirted, and Universal Height

The Nexus supports both 12” and 14” rough-in sizes, making it compatible with a variety of home configurations without the need for additional adapters. The one-piece design eliminates the seam between tank and bowl, reducing leak points and simplifying maintenance over time.

At Universal Height, the Nexus offers ergonomic comfort that complies with ADA standards when installed properly. Combined with its modern form, integrated bidet features, and hidden connections, this WASHLET+ system is a minimalist, high-tech upgrade that fits seamlessly into any bathroom.

TOTO Nexus 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.
