TOTO WASHLET® RG Lite with GP Rimless WC and Side Connections
Adjustable warm-water washing and a heated seat, paired with a rounded GP wall-hung pan. The WASHLET connects to water and power at the side.
The TOTO WASHLET® RG Lite + GP bundle pairs the RG Lite electric bidet seat TCF34120GEU with the GP rimless wall-hung toilet CW553Y. The water hose and power lead exit at the side of the seat. This layout suits new installations and retrofits where water and power can be provided beside the WC.
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
TCF34120GEU
White electric bidet seat with side connections, a soft-close seat and lid, and a wireless remote.
TOTO GP rimless pan
CW553Y
White wall-hung ceramic with CEFIONTECT glaze and TORNADO FLUSH, matched to the side-connection RG Lite.
Order the compatible support frame, concealed cistern, flush plate and any additional site-specific fittings 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 side connections and wall-hung frame
Confirm the frame and cistern
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 CW553Y drawing and the frame reference so they can check the mounting height, waste alignment and service positions together.
For a retrofit, give your installer the existing pan and frame references. Confirm the mounting, waste outlet and accessible service positions 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 position the water isolation valve and electrical connection within reach of the supplied hose and 1.2 m power lead. Both exit at the side of the seat and may remain visible after fitting. The separate flush plate operates the cistern.

TOTO RG Lite and GP side-connection 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 CW553Y GP pan. Order the compatible frame, concealed cistern, flush plate and any additional fittings separately.
Where do the water hose and power lead run?
The hose and power lead exit at the side of the RG Lite and connect to nearby services. Your installer can confirm the best positions for an accessible connection and tell you what will be visible.
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.
Can the side-connection RG Lite be fitted to an existing toilet?
TOTO lists the side-connection seat for selected compatible ceramics, including the CW553Y. Check the exact pan reference and the water and power positions with your installer. This bundle includes a new CW553Y pan.
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 the planned water and power positions. We can help check the side connection layout and identify the parts to order separately.
