TOTO WASHLET® RG Lite with NC Rimless WC and Side Connections
Adjustable warm-water washing and a heated seat, paired with the rounded NC wall-hung pan. The WASHLET connects to water and power at the side.
The TOTO WASHLET® RG Lite + NC bundle pairs the RG Lite electric bidet seat TCF34120GEU with the NC rimless wall-hung toilet CW762Y. 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 NC ceramic combines a rimless bowl, TORNADO FLUSH and CEFIONTECT glaze to make routine cleaning easier.
What comes with the RG Lite and NC set?
TOTO WASHLET RG Lite
TCF34120GEU
White electric bidet seat with side connections, a soft-close seat and lid, and a wireless remote.
TOTO NC rimless pan
CW762Y
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 fittings separately. Your installer prepares the cold-water supply, electrical connection and waste outlet.
A rimless NC bowl with TORNADO FLUSH and CEFIONTECT
The NC has a rounded front and tapers towards the base. Wall-hung mounting leaves the floor beneath the pan 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 NC pan is specified for a 3 L reduced flush and a 6 L full flush with a compatible cistern.
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 NC pan projects 530 mm from the finished wall in TOTO’s drawing and uses 180 mm fixing centres. Give your installer the CW762Y drawing and frame reference to check the mounting height, waste alignment and service positions.
The WASHLET unit is 540 mm deep. Check the assembled clearance for doors and nearby furniture before fixing the frame or finalising the layout.
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 NC 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 CW762Y NC pan. Order the compatible frame, concealed cistern, flush plate and any additional fittings separately.
Does this set need a hidden-connection kit?
The TCF34120GEU connects to nearby water and power services using the hose and lead that exit at the side of the seat. The installer plans these connections separately from the WC’s concealed cistern.
How far does the NC pan project from the wall?
The ceramic pan projects 530 mm from the finished wall in TOTO’s drawing. The RG Lite unit is 540 mm deep. Check the clearance for the assembled set when planning the room.
Can the RG Lite be fitted to an existing TOTO NC toilet?
TOTO lists the CW762Y as compatible with the side-connection RG Lite. Check the exact pan reference and the water and power positions with your installer. This bundle includes a new CW762Y pan.
Is the NC bowl rimless, and what does EWATER+ clean?
Yes. The CW762Y has a rimless bowl that TORNADO FLUSH rinses when you press the flush plate. EWATER+ cleans the RG Lite spray wand after washing or when you start a cleaning cycle from the remote.
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.

Wonderful review by Dorothy on 9/2/2025Ordered after confirming it was in stock. I was told delivery would be within seven days and that is exactly what happened. The specialist courier called ahead and arrived on time, very smooth. Fitted to a Geberit Duofix 112 cm frame without issues and everything works as it should. The wash function is simple and effective. We have a Geberit Mera from a few years ago; it is excellent but nearly five times the price, so the RG is a sensible, good value alternative. Very pleased with the purchase and the supplier.
