TOTO Washlet S5 Toilet Seat with Remote Control

The TOTO Washlet S5 (TCF34220GAU) is a premium retrofit bidet toilet seat with wall-mounted remote control. It fits most D-shaped toilet pans and upgrades any standard toilet into an intelligent hygiene system — no need to replace your entire suite.

What makes the S5 different from the S2: The S5 adds automatic lid opening and closing as you approach the toilet, plus a more refined remote control experience. If you want hands-free operation as well as bidet function, the S5 is the step up from the entry-level S2.

Key features explained:

EWATER+ — After each use, the wand automatically sanitises itself with electrolysed water, eliminating bacteria without chemicals. The bowl is also misted after flushing to keep it clean between uses.

PREMIST — Before you sit down, a fine mist coats the inside of the bowl so waste doesn’t adhere to the surface. Less scrubbing, genuinely cleaner bowl.

Heated seat with temperature control — The seat warms to your preferred setting. No cold seat shock in winter.

Oscillating and pulsating cleanse — Both rear and front wash functions with adjustable water pressure and temperature. The oscillating mode moves the wand back and forth for a thorough clean.

Auto deodoriser — Activates automatically after every use, drawing air through a carbon filter inside the seat.

The TOTO Washlet S5 is on working display at our Mascot showroom. We strongly recommend experiencing it in person before purchasing — it is the best way to understand what this product does. Book a showroom visit or call 02 9550 4628.

Installation requires a nearby power point (GPO) at the toilet. An electrician may be required if one is not already present. We can recommend a licensed installer — ask our team.

Q: What is the difference between the TOTO Washlet S5 and the S2?

A: The S5 (TCF34220GAU) adds automatic lid opening and closing as you approach the toilet, a wall-mounted remote control, and the EWATER+ nozzle sanitisation system. The S2 uses a side control panel attached to the seat and does not have the auto lid function. The S5 is the mid-range option between the S2 and the top-tier S7.

Q: Will the TOTO Washlet S5 fit my existing toilet?

A: The S5 fits most D-shaped toilet pans (383mm wide × 540mm deep). TOTO provides paper measurement templates — available in our Mascot showroom — that you place over your existing toilet to confirm fit before purchasing. You can also email a photo and your toilet model to sales@sydneybathroomware.wp.top4.website and we will confirm compatibility.

Q: Does the TOTO Washlet S5 need electricity?

A: Yes. A standard 240V power point (GPO) must be located near the toilet. If one is not already present, a licensed electrician will need to install one before the seat can be fitted.

Q: Can I retrofit the TOTO Washlet S5 onto my current toilet?

A: Yes — the S5 is designed as a retrofit seat. It replaces your existing toilet seat without requiring a new pan or cistern, provided your toilet is D-shaped and the dimensions match. Sydney Tap & Bathroomware can recommend a licensed installer experienced with TOTO Washlet fitting.

Q: Where can I see the TOTO Washlet S5 working in Sydney?

A: Sydney Tap & Bathroomware has TOTO Washlet models on working display at their showroom at 1263 Botany Road, Mascot. Open Monday to Friday, 8am–4pm. Call 02 9550 4628 to confirm availability.

Q: What is EWATER+ on a TOTO Washlet?

A: EWATER+ is TOTO’s electrolysed water technology. It automatically mists the wand after every use to kill bacteria without chemical cleaning products. It also mists the inside of the toilet bowl after flushing to reduce dirt adhesion and keep the bowl hygienic between cleans.
