TOTO Nexus WASHLET+ S5 Two Piece Toilet 1.28 GPF MW4423446CEFG#01

The TOTO Nexus WASHLET+ S5 pairs the Nexus two piece toilet (separate bowl and tank) with the WASHLET+ S5 bidet seat in one matched system. The WASHLET+ design conceals the water supply connection for a clean, seamless installation, and the completely skirted Nexus body gives smooth sides that are easier to clean. A TORNADO FLUSH system uses 1.28 gallons per flush (4.8 LPF), CEFIONTECT ceramic glaze helps keep waste from sticking to the bowl, and the S5 seat adds EWATER+, PREMIST, a heated seat, warm air dryer, automatic deodorizer and a night light inside the bowl. This is a Universal Height elongated model.

Frequently Asked Questions

Is this a one piece or two piece toilet?

This is the two piece version. The bowl (CT442CUFGT40) and tank (ST442EA) are separate pieces that bolt together. Nexus WASHLET+ S5 is also offered as a one piece (MW6423446CEFG#01); both use the same 1.28 GPF TORNADO FLUSH and the same S5 seat.

What is the difference between the S5 and the S7 or S7A?

The S5 seat has EWATER+, PREMIST, a heated seat, a warm air dryer with three settings, a deodorizer and a night light. TOTO's S7 and S7A seats add more dryer settings and, on the S7A, a touchless auto open and close lid. The S5 lid is opened by hand.

Does it have Auto Flush?

No. TOTO does not list an Auto Flush version of the Nexus WASHLET+ S5. It is flushed with the chrome trip lever.

What rough in does it need?

It is a 12 in rough in toilet. 10 in and 14 in installations are possible with the TOTO TSU10W.10 and TSU10W.14 Unifit adapters, sold separately.

Does it need an electrical outlet?

Yes. The WASHLET seat needs a grounded GFCI outlet (120 V, 15 A) near the toilet; TOTO's drawing shows it about 12 in from the floor. Plugging the seat into an extension cord is not recommended.

Is it ADA compliant?

TOTO lists it as ADA compliant for residential use when the trip lever is located on the approach side. It is a Universal Height model.
