  • Warm-Air Dryer: Three settings, 95ºF–140ºF
  • Cleaning Technology: EWATER+® on the wand, PREMIST®, self-cleaning wand
  • Compatibility: Compatible with most elongated toilets
  • Power: AC 120V, 60Hz · 1273 W
  • Warranty: One Year Limited Warranty

Front and Rear Cleansing

Gentle aerated warm water washes front and rear, with oscillating and pulsating features and three adjustable settings.

Arm Control Panel

Every function is set from the panel on the side of the seat, so there is no remote to mount, find or replace batteries in.

Heated Seat and Warm-Air Dryer

Seat temperature adjusts from 82ºF to 97ºF, and the warm-air dryer offers three variable temperature settings from 95ºF to 140ºF.

EWATER+® and PREMIST®

EWATER+® auto-cleans the wand after every use, and PREMIST® mists the bowl before each use.

Automatic Deodorizer

An automatic air deodorizer is included, which is where the S2 sits ahead of the entry models in TOTO's range.

Night Light

The night light illuminates the inside of the bowl, so the room light is not the only option after dark.

TOTO WASHLET S2 Compatibility

The TOTO WASHLET S2 works with most standard toilets. Confirm these four things before ordering:

  • Bowl shape: Available in round and elongated versions. Order the version that matches your toilet's bowl shape.
  • Tank profile: Your tank should meet the bowl at roughly a 90° angle. French curve tanks that slope into the bowl are not compatible.
  • Mounting hole spacing: Measure between the two seat bolt holes at the back of your bowl. They should be 5.5 inches apart.
  • Tank clearance: You need at least 2 inches of flat space between the front of the tank and the seat mounting holes.

For reference: The S2 fits most one-piece and two-piece toilets. Confirm your toilet bowl shape (round or elongated) and tank profile before ordering.

Installation steps

  1. Remove old seat. Clean the surface around the mounting holes.
  2. Install the seat mounting bracket.
  3. Slide the Washlet onto the bracket.
  4. Connect the hose.
  5. Turn the Washlet on.

Before you start you will need:

  • A wrench
  • A Phillips-head & flat-head screwdriver
  • A ground-fault 120-volt outlet within three feet of your toilet
  • To turn off your water supply and flush your toilet

EWATER+® auto-cleans the wand after every use.

The seamless seat eliminates the gap where dirt collects.

A docking station is listed on the sheet for easy cleaning and installation.

  • Wand cleans itself, inside and out

What do you get with the TOTO Washlet S2?

The TOTO Washlet S2 is a standalone electronic bidet seat, sold on its own rather than as part of a toilet set.

It comes elongated or round, in Cotton and Sedona Beige.

Every function is on the arm control panel — this model does not use a remote.
