TOTO TBN01202U#CP – Frequently Asked Questions
1) What comes in the box with the TOTO TBN01202U rough-in valve, and what do I still have to buy?
The TBN01202U four-hole Roman tub filler rough-in includes the valves, a decorative handshower escutcheon, and the handshower hose. Connecting tubes and water supply hoses are not included and are ordered separately. Plan on 1/2 NPSM connecting tubes, since those are what set the spread between the deck holes.
2) Will the TOTO TBN01202U rough-in valve work with my tub deck thickness?
Maximum deck thickness for the TBN01202U rough-in is 1.75 inches. Thicker decks, stone slabs, or a tile buildup over a thick substrate will put the trim out of reach, so measure the finished deck, not the bare substrate, before you set the valve.
3) Can I set the hole spacing where I want it with this TOTO four-hole tub filler rough-in?
Yes, within limits. The TBN01202U rough-in is adjustable for various spreads using the separately sold 1/2 NPSM connecting tubes, so the deck holes do not have to land on one fixed center-to-center. You pick the tube lengths to match the spread you lay out for the spout, two handles, and handshower.
4) Does the TBN01202U include the tub filler trim, or is that a separate purchase?
It is the rough-in only. The TBN01202U is the under-deck valve body assembly designed for use with a selection of TOTO four-hole tub fillers, so the spout, handles, and handshower trim are a separate order. Pick the TOTO four-hole filler first, then confirm this rough-in is the one it calls for.
5) What are the supply connections on the TOTO TBN01202U rough-in valve?
Connections are 1/2 NPSM. That is a straight-thread mechanical joint sealed with a washer or gasket rather than a tapered pipe thread, so use the matching TOTO connecting tubes and supply hoses rather than trying to thread 1/2 NPT fittings into it.
6) How much room do I need under the tub deck for the TOTO TBN01202U valve?
The valve body measures 6.125 by 2 inches, so you need access space under the deck for that envelope plus the connecting tubes running out to each deck hole and the handshower hose drop. On a framed platform, confirm the joist and skirt layout gives you a service opening before the deck goes down.
7) Is this TOTO Roman tub rough-in brass or plastic?
Solid brass construction, which is what a spec job or a multi-family rebuild usually requires for a buried deck valve. The assembly weighs 6.15 lb.
8) Does the chrome on the TOTO TBN01202U matter if the valve is hidden under the deck?
Partly. The TBN01202U is supplied in Polished Chrome, and while the valve body itself sits below the deck, the decorative handshower escutcheon that ships with it is visible on top. Match that to your filler trim finish.
