TOTO WASHLET® RG Lite with NC Back-to-Wall WC and Side Connections
Adjustable warm-water washing and a heated seat, paired with the floor-standing NC back-to-wall 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 back-to-wall toilet CW763Y. The pan stands on the floor against the finished wall and flushes from a separately ordered concealed cistern. The WASHLET’s water hose and power lead exit at the side of the seat.
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 back-to-wall pan
CW763Y
White floor-standing rimless ceramic with CEFIONTECT glaze and TORNADO FLUSH, matched to the side-connection RG Lite.
Order a compatible concealed cistern, flush plate and any waste connectors or additional fittings required for your installation separately. Your installer prepares the cold-water supply, electrical connection and waste outlet.
A rimless NC bowl with TORNADO FLUSH and CEFIONTECT
The rounded ceramic tapers towards the base and sits on the floor against the finished wall. The cistern is concealed behind the pan.
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 cistern, waste outlet and side connections
Choose the cistern and waste route
The 380 mm-wide NC pan has a nominal 630 mm projection from the finished wall. It sits on the floor and is secured using floor fixings. Select a compatible concealed cistern and flush plate separately.
TOTO’s drawing shows two floor waste arrangements (P-trap or 90° trap) and a rear wall connection. Ask your installer to measure the existing outlet and select the appropriate connector before fitting the pan.
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 back-to-wall set FAQs
What else do I need to order?
The set contains the RG Lite seat with wireless remote and the CW763Y NC pan. Order a compatible concealed cistern, flush plate and the waste connector or other fittings required for your installation. The pan is supported by the floor.
Where do the water hose and power lead run?
The hose and power lead exit at the side of the WASHLET and may remain visible. The concealed cistern supplies the flush separately.
How far does the NC pan project from the wall?
TOTO shows a nominal ceramic projection of 630 mm from the finished wall. Allow for the finished wall position and check door and furniture clearance with the assembled set.
Can the pan connect to a floor or wall waste outlet?
Yes. TOTO’s connection drawing shows both floor and rear wall options. The position of the existing waste outlet determines the connector your installer needs.
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. TORNADO FLUSH rinses the NC bowl 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 cistern reference, waste outlet position and planned water and power positions. We can help check the layout and identify the fittings to order separately.

I thought it was a ridiculous purchase, then I tried it review by Dr Elizabeth G, Kensington on 12/31/2025I fully mocked my husband for buying this. A toilet is a toilet, right. We had a cheap bidet seat years ago and the “dryer” was basically a warm breeze that did nothing. This actually dries. Properly. No sitting there waiting ages.
The best part is how little you have to think about it. Once you’ve saved your settings you’re not faffing with the remote every time. And the bowl stays cleaner than our old one. I assumed all the self cleaning talk was marketing, but it really does mean less scrubbing.
One practical thing for anyone in the UK: sort the electrics and water setup early, because your installer will not thank you if it’s an afterthought. Ours had a minor panic, then Tooaleta support talked him through it and it was fine.
It’s one of those things that sounds silly until you live with it. Now I’m the one telling friends about it.
