Sustainable Luxury

The TOTO Nexus 1G Washlet+ S7A Two-Piece Toilet brings sustainable innovation and top-tier comfort to the classic two-piece format. Combining TOTO’s eco-conscious 1.0 GPF Nexus toilet with the fully loaded S7A Washlet seat, this system delivers unmatched hygiene, hands-free functionality, and high-end style.

Enjoy features like automatic lid control, instant and unlimited warm water, four user presets, and full remote personalization—all while using only a single gallon of water per flush. This system redefines what’s possible with a two-piece toilet. For even greater convenience, the S7A supports an optional auto flush, enabling completely hands-free flushing when paired with the additional hardware kit.

Personalized Comfort

The Nexus 1G Two-Piece Toilet offers timeless appeal with contemporary features. Its skirted bowl and Universal Height design deliver both accessibility and modern style, while the two-piece construction allows for flexible installation.

Thanks to TOTO’s Washlet+ integration, cords and supply lines are fully hidden, keeping the look clean and unified. Despite using just 1.0 gallon per flush, DYNAMAX TORNADO FLUSH® provides robust, quiet, and effective bowl cleaning—making this toilet as powerful as it is efficient.
The S7A Washlet includes a beautifully minimal remote in pearl white, designed to give you full control over every seat function. With just a few taps, you can adjust spray type, nozzle position, water temperature, and activate cleansing or drying modes.

Exclusive to the S7A is support for four user presets, allowing each person to save their own settings. And with instant warm water technology, the system delivers unlimited comfort—even during back-to-back use.

Smart Features, Seamless Control

The S7A remote offers more than just cleansing control—it allows you to activate the auto open/close lid, adjust warm air drying, set seat and water temperatures, and more. The easy-to-read interface is backlit and can be wall-mounted for convenience.

The remote also enables four memory presets, ensuring that multiple users can enjoy their personalized settings with the touch of a button. Whether you need gentle or strong cleansing, warmer or cooler water, it’s all just one tap away.

Efficient by Design

This two-piece model balances traditional style with modern performance. Its skirted base conceals the trapway for a cleaner appearance and easier maintenance, while the Universal Height makes it accessible and comfortable for everyone.

Despite its eco-friendly 1.0 GPF flush, the Nexus 1G doesn’t compromise on power. Paired with the fully integrated Washlet+ system and high-tech S7A seat, it delivers a complete solution for comfort, hygiene, and sustainability—right down to the last detail.

TOTO Nexus 1G Washlet+ S7A 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.
