The TOTO NEOREST 1.2 or 0.8 GPF Dual Flush In-Wall Tank Unit is designed for use with the NEOREST WX1 or WX2 wall-hung toilet and top unit. The in-wall unit provides you with the opportunity to save up to 9 inches of floor space within your bathroom. The NEOREST in-wall tank unit is auto flush capable and provides a dual flush option for the right amount of flush for the required job. You can select between a 0.8 or a 1.2 gallons per flush with a push of a button. The harness of the NEOREST in-wall tank unit allows you to select a mounting height of 15 to 19 inches. This provides the opportunity for you to establish a comfortable bowl height for a wide array of individuals. The in-wall unit can support up to 880lbs when installed properly. The kit includes a copper water supply line and a 2" x 6" polyethylene waste outlet for installation within a 2" x 6" stud setting. If you require installation within a 2" x 4" setting, you have the option to purchase TOTO's 2" x 4" PVC outlet kit (THU343). The NEOREST toilet bowl, top unit, and push button plate are sold separately.

TOTO WT175MA – Frequently Asked Questions

1) What else do I need to order with the TOTO WT175MA in-wall tank to have a complete toilet?
The WT175MA is just the carrier and tank unit. You still need the NEOREST bowl (WX1 or WX2 wall-hung), the top unit, and the push button flush plate, all sold separately. What does come in the box is the copper water supply line and the 2 inch by 6 inch polyethylene waste outlet.
2) Will the TOTO WT175MA in-wall tank fit in a 2x4 stud wall?
Not as shipped. The WT175MA comes with a 2 inch by 6 inch polyethylene waste outlet, which is sized for a 2x6 stud bay. For a 2x4 wall you have to add TOTO's 2 inch by 4 inch PVC outlet kit, model THU343, which is a separate purchase.
3) Can I set the bowl height with the NEOREST in-wall carrier for an accessible or comfort height install?
Yes. The carrier harness on the WT175MA adjusts the bowl mounting height anywhere from 15 to 19 inches, so you can dial in a comfort height seat or drop it lower for a shorter user without changing hardware. Set it before the wall is closed in, since the adjustment is behind the finished surface.
4) Can I use the WT175MA carrier with a non-NEOREST wall-hung bowl?
It is built for the NEOREST WX1 and WX2 wall-hung bowls and their top unit. Spec it against those. If your bowl is a different TOTO wall-hung model or another brand, look for the carrier matched to that bowl instead, because the bowl mounting studs, waste spigot location and the electronic connections are all part of the NEOREST system here.
5) How much floor space does a NEOREST in-wall tank actually save over a floor-mount toilet?
Moving the tank into the wall frees up to 9 inches of floor depth in the bathroom. For a small powder room or a tight multi-family layout that is usually the difference between a workable clearance in front of the bowl and a door that will not swing. It also leaves clear floor under the bowl, which speeds up cleaning in hospitality and healthcare washrooms.
6) Is the TOTO WT175MA dual flush, and what are the flush volumes?
Dual flush, yes. You get 1.2 gallons per flush for solids and 0.8 GPF for liquids, selected at the push button plate. The unit is also auto flush capable if you are pairing it with a NEOREST top unit that drives automatic flushing, which is the usual spec in commercial and hospitality washrooms.
7) Does the TOTO NEOREST in-wall tank need batteries or power?
No batteries are supplied or used with the WT175MA tank unit itself. The auto flush and electronic functions on a NEOREST run off the bowl and top unit, so plan the electrical rough-in for those components rather than for the carrier.
8) What size flush valve is in the TOTO WT175MA tank unit?
It uses a 2 inch flush valve. That is the larger of the two common valve sizes and is what lets the 1.2 GPF setting move waste with a short, fast discharge on a wall-hung bowl.
