TOTO TBN01201U – Frequently Asked Questions

1) Does the TOTO TBN01201U rough-in valve come with the tub filler trim, or do I order that separately?
The TBN01201U is the rough-in valve body only. It is built for use with a selection of TOTO three-hole Roman tub fillers, and the trim (spout and handles) is a separate order. The connecting tubes and water supply hoses are also sold separately, so a complete job needs three line items: this valve, the connecting tubes, and the TOTO three-hole filler trim you have specified.
2) Can the TOTO three-hole Roman tub rough-in valve be set to different handle-to-spout spreads?
Yes. Spread is adjustable, but only once you add the 1/2 NPSM connecting tubes, which are ordered separately. The tubes are what set the distance between the two handle bodies and the spout, so the deck hole layout is not locked to one fixed dimension. Decide your spread before drilling the deck, then order tube lengths to suit.
3) What thickness of tub deck will the TBN01201U rough-in valve mount through?
Up to 1.75 inches of deck. That covers most stone, solid surface and tiled tub decks, but if you are building a thick slab top or stacking tile over a mortar bed, measure the finished stack first. Anything over 1-3/4 inches means relieving the underside of the deck at each hole or the shanks will not reach through for the mounting hardware.
4) What connection type do I need to plumb into on a TOTO TBN01201U tub filler valve?
The valve connects at 1/2 NPSM. That is a straight-thread hose connection, not tapered pipe thread, so it seals on a gasket or washer rather than on thread engagement, and it mates with the TOTO connecting tubes and supply hoses made for it. Do not try to thread 1/2 NPT pipe or a soldered male adapter directly into it.
5) Does the TBN01201U work with a single-hole or two-hole deck-mount tub filler?
No. It is a three-hole Roman tub configuration, meaning two separate handle valve bodies and a spout, each in its own deck hole. A single-hole floor or deck filler and a two-hole layout both need different rough-in hardware. If your deck is already drilled, count the holes before ordering this one.
6) Is the TOTO tub filler rough-in valve body brass or plastic?
Solid brass throughout the body. That matters on a deck-mount tub filler because the valve gets buried under a finished deck and is not coming back out without demolition, so the buried component should be metal. The single orderable configuration is the brass body, MPN TBN01201U.
7) How much room do I need under the tub deck for the TOTO TBN01201U valve?
Plan the access opening around a valve measuring 5.125 by 2 inches, and remember that is the body alone. You still need clearance under it for the 1/2 NPSM connecting tubes running across to the spout and for the supply hoses coming up to each side. On a platform tub, keep a removable access panel at the filler end rather than sealing the deck permanently.
8) Is the finish of the TBN01201U rough-in valve going to be visible once the tub filler is installed?
No, and it does not need to match your trim. The valve is supplied in brass and sits below the deck; the finish you see at the tub is whatever TOTO three-hole filler trim you pair with it. So you pick the rough-in by function and the trim by finish, independently.
