Classic Comfort, Modern Features

The next generation TOTO Washlet S5 is a refined bidet seat that blends time-tested hygiene with modern convenience. Designed to fit most elongated toilets and round toilets, the S5 delivers a luxurious cleansing experience through instant and continuous warm water, a heated seat, and a gentle warm air dryer. PREMIST sprays the bowl before use, helping prevent waste from sticking and reducing the need for frequent cleaning.

It features front and rear wash options, five spray settings, oscillating and pulsating modes, and four user presets—all controlled via a sleek wireless remote. Whether you're upgrading your bathroom for comfort, wellness, or convenience, the S5 is the perfect companion.

A Clean Look with Custom Control

Designed for seamless integration, the Washlet S5 has a slim profile that complements most modern toilets. The seat features a gentle curve and a lid that covers the back section fully, making for a clean, low-profile look from every angle.

The S5 replaces your existing toilet or bidet seat easily, especially when paired with a Washlet+ compatible toilet. The SoftClose® seat and lid prevent slamming, and the quick-release design makes cleanup effortless.
The S5's design is all about ease and elegance. From the smooth lid surface to the tucked-away nozzle housing, every detail is carefully considered for performance and appearance. The seat is contoured for comfort, and the controls are simple to master.

Packed with features at a modest price, the S5 remains one of TOTO’s most popular models thanks to its strong balance of features, reliability, and value.

Thoughtful Design, Front to Back

The S5's newly designed ergonomic remote control puts a personalized experience one touch away, where you can control various wash settings, the heated seat, warm air dryer, and automatic deodorizer to neutralize odors for a clean, relaxing experience.

Four user presets let you save personalized settings, so your preferred experience is always just a button away. The remote can be mounted on the wall for convenient access without disrupting your bathroom design.

Fit, Form, and Function

The Washlet S5 fits most standard elongated or round toilets and installs in thirty minutes using the included mounting hardware and connection kit. It runs off a standard GFCI outlet and connects easily to your toilet’s water supply using a T-connector.

Its sleek silhouette measures just under 21 inches front to back and less than 6 inches tall at the rear. With discreet connections and soft contours, it enhances your bathroom without drawing attention.

TOTO Washlet S5 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 S5 is likely to be a perfect fit.

TOTO Washlet S5 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.
