Installing a clawfoot tub faucet is mostly about planning: the faucet, its supply lines and the drain all have to line up with the tub and your plumbing. Here's what's involved, so you can order the right parts and brief your plumber.
1. Know your mount and centers
Decide whether the faucet sits on the rim (deck mount, usually 7" centers), goes through the tub wall (usually 3 3/8"), or comes out of the bathroom wall. How to choose a clawfoot tub faucet explains each one, and variable center faucets fit holes that measure in between.
2. Gather the parts
- Supply lines. These carry water from the floor or wall up to the faucet. Our freestanding tub supply set with shutoffs comes in 24" and 28" heights. For deck-mount faucets, the 29" deck mount supply set stands 32" from deck to floor.
- Shutoff valves, so the faucet can be serviced without turning off the house water.
- Couplers, which join the faucet to the tub or wall: 90-degree deck couplers, 6" swing-arm couplers for adjustable spacing, or modified swing-arm couplers to mount a tub faucet on the wall.
- A drain with an overflow. Our P0007 waste and overflow drain fits most leg tubs made from 1900 on, with chain and stopper, lift and turn, or toe touch.
Want it in one box? The faucet and over-the-rim supply set pairs a 7" center faucet with 24" supplies.
3. The order of work
- Rough in the supply lines and drain to suit the tub's final position, before the finished floor goes down.
- Set the tub and install the drain and overflow.
- Mount the faucet to the tub or wall with its couplers.
- Connect the supply lines and shutoffs, then the handshower if your faucet has one.
- Turn the water on slowly, run the faucet, and check every joint for leaks.
4. Bring in a plumber
Follow the installation instructions for your model, and have a licensed plumber make the connections, especially any work inside walls or under floors.
