Modern Comfort Meets Simplified Control

The TOTO WASHLET S2 is a thoughtfully designed bidet seat that brings comfort and cleanliness to your daily routine. With a sleek, modern silhouette that's 19% slimmer than previous models, it offers full-size functionality with a smaller environmental footprint. The compact design pairs seamlessly with most elongated toilets and elevates the look of any bathroom.

This next-generation seat delivers the premium feel you'd expect from TOTO, without unnecessary complexity. It focuses on intuitive features that make each use feel like a luxury, while maintaining simplicity that fits into everyday life.

Tankless Warm Water, Anytime

  • The WASHLET S2 uses an advanced tankless water heating system that provides instantaneous and continuous warm water. Unlike older models with limited-capacity reservoirs, this system heats water on demand, so you're never left waiting or running cold mid-cleanse.

    Temperature and pressure can be adjusted easily using the side panel, giving you complete control over the experience. Whether you prefer a warm, gentle stream or something more invigorating, the S2 adapts to your preferences with ease.

  • Comfort is at the core of the S2’s design. A heated seat with adjustable temperature keeps you warm and relaxed, especially during colder months. The warm air dryer reduces dependency on toilet paper while offering a gentle, effective drying option.

    Additional thoughtful touches—like the automatic deodorizer, which helps eliminate bathroom odors, and the built-in nightlight—make the S2 a practical upgrade for both everyday comfort and nighttime convenience.

Cleansing Made Effortless

Instead of a wireless remote, the S2 features an integrated side-arm control panel that makes operation simple and accessible. Positioned on the right side of the seat, the control panel offers clear, easy-to-press buttons with intuitive icons for key functions like cleansing mode, water pressure, temperature, and dryer settings.

This design makes it an excellent option for households that prioritize accessibility, reliability, and ease of use. There's no need to keep track of a separate remote, and users of all ages can operate it confidently without prior experience.

Perfect Fit, Clean Design

The S2 includes advanced features to help maintain a cleaner, more hygienic bathroom with minimal maintenance. PREMIST® sprays the bowl before each use to help reduce waste buildup and staining, limiting the need for frequent manual scrubbing.

EWATER+® technology ensures the wand is automatically sanitized with electrolyzed water before and after every use. Combined, these features create a low-maintenance and highly hygienic environment, making the S2 a practical and reliable choice for daily wellness.

TOTO Washlet S2 Fitment

  • To ensure your brand new bidet seat will fit on top of your toilet, determine the size and shape of your bowl. Most toilet bowls come in one of two standard shapes:

    1. Elongated: Common in modern toilets and typically around 18.5" in length
    2. Round: Common in older toilets or smaller bathrooms and around 16.5" in length

    Once you determine what shape bidet seat you need, check these three things:

    1. There should be at least 5.5" of space between the seat's bolt holes.
    2. There should be at least 2" of space between the seat's bolt holes and the toilet tank.
    3. If your toilet meets the tank at or near a 90-degree angle, the TOTO Washlet S2 is likely to be a perfect fit.

TOTO Washlet S2 Installation

Bidet seats install like a classic toilet seat and you can follow the included installation instructions without hiring a plumber. There are only a few additional factors to consider:

  • Make sure your toilet can accomodate a bidet seat with this guide
  • Access to a standard GFCI electrical outlet is required for your bidet seat to function.
  • Your bidet seat will utilize the same water connection that fills the toilet's tank via an included T-valve.
  • See the video guide below for help installing your new TOTO Washlet S2!

Toto washlet

I was pleased to find such a wide variety of Toto washlets, and found exactly the one I was looking for quickly. shipping was quick and it arrived in good condition. Was a breeze to install as well. I have recommended this local company to several of my friends as well.

The C2 is perfect for daily needs, and I prefer the attached control panel over a remote that I can lose (C7).
