A floor-mount faucet (also called a tub filler) adds a touch of sophistication to a freestanding or clawfoot bathtub and creates an elegant design statement.

This project describes how to install a floor-mount faucet once the rough plumbing is in place beneath the floor. The advantage of a freestanding installation is that the work area is unrestricted since the faucet pipe is exposed (no walls, access panels, etc.). The project is simple and straightforward. No soldering is involved; however, it may be necessary to reinforce the floor, requiring basic carpentry skills.


Tools and materials required


  • Adjustable wrench
  • Screwdriver
  • Pipe cutter
  • Rag
  • Pencil
  • Level
  • Drill
  • Jigsaw


  • Thread seal tape
  • Floor-mount faucet


Before Assembly


For this project, it is assumed that the water supply and drain pipes are already in place beneath the floor and are directly accessible.

Before installing the bathtub and faucet, make sure the floor is perfectly level and sturdy. The floor must be strong enough to support 50 lb/sq. ft.

Two types of floor-mount tub fillers are available: single-riser (single-leg or monobloc) models and dual-riser models. The installation method differs for each. Single-riser faucets are completely freestanding and so must be secured firmly to the floor, while those with two risers are also attached to the tub drain or the wall. The following project provides detailed steps on how to install a single-riser faucet.

The exposed section of the faucet is installed once the finished floor is in place, to prevent any damage to the pipe.

Turn off the water supply by closing the shut-off valves. If there are no shut-offs, close your home's main water valve.

The following steps may vary depending on the faucet model. Refer to the manufacturer's installation instructions.
