Overview

Advanced hygiene. Instant warm water. Luxury bathroom technology.

The TOTO WASHLET S2 Electronic Bidet Toilet Seat introduces spa-level hygiene and comfort to everyday bathroom routines. Designed with a tankless instantaneous water heater, the seat provides a continuous stream of warm cleansing water without the limitations of a traditional heated tank.

The system features PREMIST technology, which lightly sprays the toilet bowl before use to help prevent waste from adhering to the surface. The wand automatically cleans itself inside and out using EWATER+, an electrolyzed water system that helps maintain hygiene while reducing the need for harsh cleaning chemicals.

Comfort and convenience features elevate the experience even further with a heated SoftClose® seat, adjustable warm air dryer, deodorizer, and nightlight. The integrated side control panel allows users to customize water temperature, spray position, pressure, and cleansing modes for a personalized experience.

With its slim tankless design and advanced cleansing technology, the WASHLET S2 brings modern luxury and improved hygiene to contemporary residential bathrooms and hospitality-style interiors.
