Sleek Design. Intelligent Comfort.

The TOTO Nexus WASHLET+ Toilet blends smooth, modern lines with powerful performance. This fully skirted two-piece model offers a sleek base that conceals the trapway, creating a seamless profile that’s easy to clean and ideal for contemporary bathrooms. Its gently curved tank pairs with the skirted bowl for a minimalist design that still feels substantial and sculpted.

Despite its streamlined appearance, the Nexus delivers exceptional performance with a 1.28 GPF TORNADO FLUSH® system that uses dual-nozzle action to clean the bowl thoroughly with every flush. The CEFIONTECT® ceramic glaze ensures waste doesn’t stick, supporting a cleaner, more hygienic experience between cleanings.

Modern Form, Personalized Control

The Nexus comes equipped with the advanced WASHLET S5 bidet seat, integrated into the toilet with hidden water and power lines for a sleek, polished finish. The S5 offers continuous warm water cleansing, a heated seat, air dryer, deodorizer, and nightlight—all accessible through an intuitive, backlit wireless remote.

With support for up to four user presets, the S5 lets each household member store their ideal combination of spray mode, pressure, temperature, and nozzle position. This makes it easy to enjoy a personalized hygiene routine without adjusting settings every time.
The Nexus WASHLET+ system includes TOTO’s full suite of cleanliness technologies. PREMIST® sprays the bowl with a fine mist before each use to help reduce residue and improve flushing performance. After use, EWATER+® rinses the wand inside and out using electrolyzed water, providing automatic sanitization without harsh chemicals.

The smooth, skirted base simplifies exterior cleaning by eliminating nooks and crevices around the trapway. Combined with the stain-resistant CEFIONTECT® glaze and powerful flush, the Nexus reduces the need for scrubbing and keeps your bathroom feeling fresher longer.

Intuitive Washlet Controls

With the S5 remote, you can control every aspect of your WASHLET experience at the touch of a button. Toggle between oscillating and pulsating spray modes, fine-tune water pressure and nozzle position, or adjust the seat warmth and drying intensity. The slim remote can be handheld or wall-mounted and features clearly labeled buttons with icons and text.

You can also save your preferences using the four built-in user presets, making it simple to return to your favorite settings each time you use the toilet. Whether you want a gentle, spa-like clean or a quick refresh, the Nexus adapts instantly to your needs.

Sleek, Skirted, and Universal Height

The Nexus is available in both 12" and 14" rough-in configurations, offering greater flexibility for new builds or remodels without needing an adapter. Its Universal Height bowl provides accessible comfort for a wide range of users and meets ADA standards when installed correctly.

As part of the WASHLET+ series, all connections are concealed within the toilet, leaving a clean silhouette that’s as refined as it is functional. With its fully skirted base and smart bidet integration, the Nexus WASHLET+ S5 offers a complete upgrade in both design and hygiene.

TOTO Nexus 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.
