TOTO WASHLET® RG Lite with GP Rimless WC and Hidden Connections
Adjustable warm-water washing and a heated seat, paired with a rounded GP wall-hung pan prepared for concealed water and power connections.
The TOTO WASHLET® RG Lite + GP bundle pairs the RG Lite electric bidet seat TCF34120GGB with the GP rimless wall-hung toilet CW553EY. The matching pan has dedicated openings for the water hose and electrical cable, keeping both out of sight when fitted to prepared services with the appropriate connection parts.
Choose from three warm-water sprays and adjust the seat warmth from the remote. EWATER+ cleans the wand automatically after washing. The GP ceramic combines a rimless bowl, TORNADO FLUSH and CEFIONTECT glaze to make routine cleaning easier.
What comes with the RG Lite and GP set?
TOTO WASHLET RG Lite
TCF34120GGB
White electric bidet seat with hidden connections, a soft-close seat and lid, and a wireless remote.
TOTO GP rimless pan
CW553EY
White wall-hung ceramic with CEFIONTECT glaze and TORNADO FLUSH, prepared for concealed WASHLET connections.
Order the compatible support frame, concealed cistern, flush plate and frame-specific connection parts separately. Your installer prepares the cold-water supply, electrical connection and waste outlet.
A rimless GP bowl with TORNADO FLUSH and CEFIONTECT
The GP’s curved front softens the outline of the WC, while the wall-hung mounting leaves the floor beneath it clear for cleaning.
Rimless bowl
The open bowl edge gives you direct access for wiping around the top of the ceramic.
TORNADO FLUSH
Directed water creates a swirling rinse around the bowl when you press the flush plate. The compatible concealed cistern determines the flush volumes.
CEFIONTECT glaze
TOTO’s smooth ceramic glaze helps reduce residue adhesion, making routine wiping easier. Follow the ceramic care instructions to protect the finish.
Set the wash, warmth and spray position to suit you
Three sprays with precise adjustment
Choose rear, soft rear or front washing. Five pressure levels and five wand positions let you direct the spray while seated. Oscillation moves the wand backwards and forwards for wider coverage. The massage mode alternates spray pressure.
Continuous-flow warm water and a heated seat
The RG Lite heats the incoming cold water as it flows. Choose from three wash-water temperatures and three seat temperatures, with heating-off settings for each. The seat and lid lift by hand and close gently.
Two personal memories
Save two combinations of pressure, wand position and wash-water temperature. Recall your preference from the wireless remote, then choose a wash. Set the seat temperature separately.
EWATER+ wand cleaning
After washing, the RG Lite uses electrolysed tap water to clean the wand. You can also start an EWATER+ cleaning cycle from the remote. The wand sits behind a protective flap above the bowl between uses.
The RG Lite has a built-in descaling programme and a removable spray nozzle for manual descaling. Follow TOTO’s instructions for the recommended descaling agent and cleaning method. Automatic and timed energy-saving settings let you manage seat heating around your routine.
Plan the concealed connections before tiling
Confirm the frame and connection parts
The 380 mm-wide GP pan projects 540 mm from the finished wall in TOTO’s drawing and uses 180 mm fixing centres. Give your installer the CW553EY drawing and the frame reference so they can check the mounting height, waste alignment and service routes together.
The SP10695UN hidden-connection set is sold separately. TOTO specifies it for compatible TOTO WASHLET frames or Geberit Sigma Duofix frames with a 50 mm service conduit. Confirm the exact frame and connection arrangement with your installer before ordering.
Prepare water, power and access
TOTO specifies potable cold water with a minimum 1.0 bar dynamic pressure and a maximum 10.0 bar static pressure, plus a 220–240 V AC, 50 Hz supply for the RG Lite.
Have your installer plan the concealed routing, accessible isolation and electrical connection before mounting the pan. The separate flush plate operates the cistern.

TOTO RG Lite and GP set FAQs
Do I need to order a cistern and frame as well?
Yes. The set contains the RG Lite seat with wireless remote and the CW553EY GP pan. Order the compatible frame, concealed cistern, flush plate and connection parts separately.
What does “hidden connections” mean?
The installer routes the water hose and power cable through the CW553EY pan’s service openings. The finished WC uses a cold-water connection and mains electricity for the WASHLET functions.
How far does the GP pan project from the wall?
TOTO’s drawing shows a nominal 540 mm projection from the finished wall. The pan measures 380 mm wide, and the frame setting determines the installed sitting height.
What does the RG add over the RG Lite?
The RG adds PREMIST bowl preparation and an automatic deodoriser. Both versions offer adjustable warm-water washing, a heated seat and EWATER+ wand cleaning.
What does EWATER+ clean on the RG Lite?
EWATER+ cleans the spray wand after washing or when you start a cleaning cycle from the remote. The GP bowl is rinsed by TORNADO FLUSH when you press the flush plate.
How do I open, flush and dry with the RG Lite?
Lift the seat or lid by hand, use the remote for washing and pat dry afterwards. Operate the WC with the separate flush plate. The seat and lid have soft-close hinges.
Check the set against your bathroom plans
Send Tooaleta your frame or cistern reference and tell us whether the wall is already finished. We can help check the concealed connection route and identify the parts to order separately.

Wonderful solution review by Anthony_Har on 1/6/2025Ordered after confirming stock and delivery was promised within 10 days—which it was. The specialist delivery went smoothly and arrived as scheduled. The toilet was installed on a Geberit Duofix 112cm frame and the installation was straightforward. The system works perfectly with an effective and easy-to-use wash function. We previously installed a high-end TOTO model which has more advanced features but costs nearly 10 times more. This is a fantastic budget-friendly alternative and we're very happy with both the product and the supplier.
