The Pinnacle of Japanese Hygiene & European Design
TOTO WASHLET™ RW White Trim + RP Wall-Hung WC — Complete Bundle
The TOTO WASHLET™ RW in White Trim represents the ultimate standard in Japanese smart toilet technology, arriving as a complete, ready-to-install bundle. Paired with the award-winning TOTO RP wall-hung ceramic bowl, every connection between the seat and the bowl routes invisibly through the pan, leaving nothing but a pristine, floating silhouette tailored perfectly for the modern British bathroom.
The White Trim edition delivers far more than elegant aesthetics. The seat, wand jet, and housing are meticulously crafted from TOTO’s silicone-based Clean Resin — a patented material that actively repels dirt. Furthermore, the seamless seat ring entirely eliminates the crevices where bacteria typically accumulate in conventional toilet seats. This is not merely a bidet seat added to a toilet; it is a fully integrated, state-of-the-art hygiene system.
🔭 The Science of Clean Resin: A Material, Not a Coating
While many bidet seat manufacturers apply temporary surface finishes to improve cleaning, TOTO engineered a fundamentally superior material. The RW’s housing, wand jet, and seat ring are crafted from Clean Resin — a highly advanced, silicone-containing compound that possesses an inherently lower surface adhesion than standard ABS plastics. Dirt, limescale, and bacteria find significantly less surface area to grip.
Because this is not a surface treatment that wears away over time, the hygiene properties of the RW are permanent. Combined with TOTO's EWATER+ automated cleaning technology, the White Trim RW is engineered to maintain a flawlessly hygienic state with minimal manual intervention.

WASHLET™ RW Features & RP Ceramic Benefits
Uncompromising Hygiene
- EWATER+: Following every use, electrolysed water automatically cleans the wand jet (inside and out) and sprays the ceramic bowl. It breaks down microscopic bacteria without the need for harsh chemicals.
- PREMIST: A fine water mist coats the ceramic bowl prior to use, making it exceptionally difficult for waste to adhere to the surface.
- Clean Resin Housing: A silicone-based material on the unit, wand, and seat ring that actively resists dirt build-up permanently.
- Seamless Seat Ring: Eliminates the joins and crevices where bacteria usually colonise — a crucial hygiene advantage.
- Quick-Release System: The entire seat unit lifts away from the ceramic bowl in one simple step, allowing for deep cleaning underneath.
Personalised Comfort
- Warm Water Wash: Enjoy rear wash, front wash, oscillating, and pulsating massage modes. Water pressure, temperature, and nozzle position are all entirely customisable.
- Continuous Heating: Water is heated instantly on demand. No bulky internal tank means no waiting, and it greatly reduces the risk of limescale build-up.
- Customisable Wand Jet: The spray wand can be adjusted to different positions, ensuring pin-point accuracy and maximum comfort for every individual user.
- Heated Seat: Features an ergonomic, seamless design that warms rapidly upon your approach, with fully adjustable temperatures.
- Warm Air Dryer: Adjustable from 37–55°C, offering a gentle, paper-free finish.
- Deodoriser: An active carbon filter operates continuously during and after use, neutralising odours without needing replacements.
Automation & Intelligence
- Auto Lid: The sensor detects your approach, opening the lid automatically and closing it softly as you leave. A completely touch-free experience.
- Soft Night Light: A gentle side light illuminates the bowl in darkened rooms, protecting your natural sleep cycle without needing overhead lighting.
- 2-User Memory: The sleek remote control saves the exact preferred settings for two different users.
- Energy Saving Mode: The system automatically learns your usage patterns and activates energy-saving protocols during non-use periods.
- Smart Descaling: The unit automatically alerts you when descaling is required, making maintenance in UK hard-water areas effortless.
The Ceramic: TOTO RP (CW542ERY) — Engineered for WASHLET
The RP is not simply a standard toilet bowl modified with drilled holes. It is engineered from its inception to be the perfect ceramic partner for TOTO’s bidet seats, featuring three core technologies that ensure peerless cleanliness:
- CEFIONTECT Glaze: Applied before firing, this ultra-smooth ceramic finish ensures a microscopic smoothness that prevents waste, mould, and limescale from gripping the surface. It is exceptionally resilient and will not wear off.
- Rimless Design: Without an inner rim, there are absolutely no hidden ledges for bacteria or limescale to accumulate. The bowl is fully visible and effortlessly easy to wipe down.
- TORNADO FLUSH: Water is propelled as a powerful centrifugal vortex, cleaning the entire bowl thoroughly with a highly efficient 4.5-litre flush. It is significantly quieter than standard downward-jet UK systems, with virtually zero aerosol spray.
All water and electrical connections route internally through the ceramic pan — ensuring no exposed hoses or trailing cables disrupt your bathroom's design. Included FlexCover caps allow you to safely seal the connection ports should you wish to install and use the bowl before fitting the WASHLET unit.

Frequently Asked Questions
No. All four RW finishes — White Trim, Silver Trim, Matte White, and Matte Black — share the exact same Clean Resin material and EWATER+ self-cleaning system. The Matte White and Matte Black editions utilise a fired CEFIONTECT matte glaze on the ceramic, which is just as highly durable and non-porous as the standard high-gloss finish. None of these models require harsh or abrasive cleaning products.
This bundle provides the WASHLET RW seat unit (TCF801EAG#NW1) and the perfectly matching RP ceramic bowl (CW542ERY). To complete your bathroom setup, your plumber will also need a compatible concealed in-wall cistern frame (such as a standard 180mm-centre frame from Geberit, Grohe, or TOTO) and a suitable flush plate. An electrician will need to provide a standard UK 220–240V fused spur connection. If you wish to utilise the Auto-Flush feature, the specific TOTO Frame System WH182EAT must be installed.
No, the design is entirely seamless. The RP ceramic is specially pre-drilled with internal routing channels engineered for WASHLET connections. Both the water supply hose and the power cable are fed through the inside of the ceramic bowl and exit at the rear directly into your in-wall frame cavity. Nothing is visible from the front or sides of the toilet.
It features instant, continuous heating. The RW utilises an advanced inline ceramic heater that warms the water instantly on demand as it flows through the system. There is no reservoir being kept permanently hot, which completely eliminates the limescale build-up associated with older tank heaters and drastically reduces your household's standby energy consumption.
Absolutely. The WASHLET RW proudly holds WRAS (Water Regulations Advisory Scheme) Approval Number 2005342. This rigorous certification confirms full compliance with UK Water Supply (Water Fittings) Regulations. You can install it with complete peace of mind.
Yes, you can. TOTO includes FlexCover caps that neatly seal the WASHLET connection ports in the ceramic. This allows the bowl to function beautifully as a standard, high-quality rimless WC until you are ready for your plumber to fit the smart seat.
After every flush, the WASHLET sprays EWATER+ — standard tap water that has been temporarily electrolysed to give it enhanced antibacterial properties — directly onto the ceramic surface. Working in tandem with the PREMIST cycle (which mists the bowl before use), the ceramic is continually conditioned. The EWATER+ breaks down safely into ordinary water shortly after contact, making it entirely safe for UK drainage systems and highly eco-friendly.
