Before you start
For this project, it is assumed that the water supply and drain pipes are already in place and directly accessible beneath the floor.
Before installing the bathtub and faucet, you need to make sure the floor is perfectly level and sturdy. It must be strong enough to support 50 lb/sq. ft.
There are two types of floor-mount tub fillers 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 additionally 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.
Before you begin, turn off the water supply by closing the shut-off valves. If there are no shut-offs, then you will need to close your home's main water valve.
The following steps may vary depending on the faucet model. Make sure you refer to the manufacturer's installation instructions for more details.
