Buy more, save more: buy 4+, extra 15% off · Buy more, save more: buy 3, extra 10% off
An in-wall carrier and concealed tank for wall-hung toilets, built around TOTO's DYNAMAX TORNADO dual-flush system with a 0.9 GPF light flush and a 1.28 GPF full flush. It is ready for auto flush and comes pre-plumbed with a copper supply for a WASHLET seat.
The harness sets the bowl anywhere from 15 to 19 in. high, so the height can suit the people using it, and the installed frame carries up to 880 lb. Moving the tank into the wall frees up to 9 in. of floor space compared with a standard floor-mount toilet and leaves the floor open for easier cleaning. The tank is a single blow-molded polyethylene piece designed to resist leaks.
Out of the box it suits 2 x 6 stud framing with a 2 in. x 6 in. polyethylene waste outlet; 2 x 4 walls need TOTO's THU343 PVC outlet kit. The THU794 WASHLET connection kit completes a bidet seat hookup to the built-in copper line. The wall-hung bowl, an auto flush compatible WASHLET and the push plate are separate items.
