TOTO TSU08W.10 – Frequently Asked Questions
1) Can I use a TOTO toilet on a 10 inch rough-in with the TSU08W.10 adapter?
That is exactly what the TSU08W.10 Unifit outlet adapter trapway does. It converts a compatible TOTO toilet from the standard 12 inch rough-in down to a 10 inch rough-in, so a bowl designed for 12 inches can sit on an older 10 inch waste line. It only works with TOTO toilets built for the Unifit adapter system, so confirm the bowl model accepts a Unifit trapway before ordering.
2) What else do I need to buy to install a TOTO Unifit trapway adapter?
Plan on a wax ring and floor drain (closet) bolts, neither of which comes with the TSU08W.10. The adapter itself ships with the hardware to anchor it to a tile or wood floor, and the rubber gasket that seals to the ceramic bowl is already fitted to the PVC body. So the only trip to the truck is for the wax ring and the flange bolts.
3) Is the TOTO TSU08W.10 a genuine TOTO part or an aftermarket trapway?
Genuine TOTO, sold under manufacturer part number TSU08W.10. For a property manager or facilities buyer standardizing on TOTO fixtures, that matters: the Unifit adapter is a sealed system between the PVC trapway and the ceramic bowl, and the bowl's gasket interface is made to the manufacturer's own part.
4) Can the TSU08W.10 Unifit adapter be anchored to a tile floor, or only to wood subfloor?
Either one. The adapter comes with hardware for securing it to tile or to a wood floor, so a bathroom remodel over a tiled slab and a wood-framed floor both use the same part. You still set the bowl on a wax ring over the adapter outlet and bolt it down with closet bolts, which are bought separately.
5) Is the Unifit trapway adapter plastic, and will it hold up in a commercial restroom?
The body is PVC with a rubber gasket at the bowl connection. It is not a visible part once installed, it sits under the ceramic and behind the bowl skirt, carrying waste from the bowl outlet back to the flange location. PVC is standard drain material for that duty, and the ceramic bowl bears on the floor, not on the adapter.
