8 "Must-Know" Features of the TOTO Washlets

Upgrade your bathroom with the TOTO Washlets, a high-tech toilet seat designed for comfort, hygiene, and convenience. Here are the 8 key features that make them stand out — all of them found across our range of TOTO Washlet bidet seats.

1. Auto Open / Close (S7A Only)

The lid automatically opens and closes when you approach or leave the toilet — no need to touch the seat, perfect for hygiene.

2. Night Light

S7A and S7: Bowl light + side light
S5 and S2: Bowl light only

Provides subtle illumination for nighttime visits without harsh overhead lighting.

3. EWATER+® for Wand

The wand cleans itself inside and out with EWATER+, keeping it hygienic for every use.

4. EWATER+® for Bowl (S7A and S7 Only)

EWATER+ prevents waste buildup on the bowl and reduces hidden residue, making cleaning easier.

5. Heated Seat

The seat warms automatically when you approach, giving immediate comfort — ideal for colder mornings.

6. Deodorizer

7. Warm Air Drying

8. PREMIST®

A film of water is sprayed on the bowl before use to prevent waste from sticking, ensuring easier flushing and cleaner results.

Why the TOTO Washlet Stands Out?

The TOTO Washlet combines comfort, technology, and hygiene in a single product. From self-cleaning wands to heated seats and deodorizing, every feature is designed to make your bathroom experience effortless and enjoyable.

Not every model carries all eight — Auto Open/Close and EWATER+ for the bowl are S7A and S7 only. Compare the range in Washlets & smart bidet seats, or, if you would rather have the Washlet built into the toilet itself, see TOTO smart toilets and the full TOTO collection.

Frequently Asked Questions

What makes a TOTO WASHLET different from a standard toilet seat?

For anyone seeking upgraded bathroom comfort, stronger hygiene features and long‑term durability, a TOTO WASHLET is a smart investment. They offer features like warm‑water cleansing, seat heaters, air dryers and deodorization. Given the quality materials and advanced functions, they tend to have a longer lifespan than many standard fixtures making the upfront cost justified over time.

Can I install a TOTO WASHLET in an existing bathroom? What electrical and plumbing requirements are there?

Yes, many TOTO WASHLET models are compatible with existing toilets provided you have a 120 V AC outlet (60 Hz) and proper water supply. Some models require a dedicated circuit or power outlet near the toilet. Confirm compatibility with your toilet bowl and check you have proper wiring and outlet positioning before installation.

How much maintenance do TOTO WASHLETs require and how energy‑efficient are they?

TOTO advises regular cleaning with a soft cloth and mild detergent; no harsh chemicals or abrasive materials should be used. Some models include automatic descaling programs and self‑cleaning wand features. Energy‑wise, depending on model and usage, a four‑person household may use ~140‑180 kWh per year with energy‑saver models. Use varies based on model and settings.
