How to Install a Bathtub Faucet

A bathtub spout or faucet comes in two basic styles. The set-mounted spout has a hole on the bottom of the faucet and it is mounted with a set screw. In this type of spout, the fitting is moved over the pipe unit it is against the wall, and a set screw is tightened. The other common spout type is the screw-on.

A bathtub spout or faucet comes in two basic styles. The set-mounted spout has a hole on the bottom of the faucet and it is mounted with a set screw. In this type of spout, the fitting is moved over the pipe unit it is against the wall, and a set screw is tightened. The other common spout type is the screw-on. With a screw-on there is no set screw, and the faucet is screwed into place, which can be more difficult to square.

  1. Remove the old faucet if you are replacing it with a new one. To do this, loosen the screw on the bottom of the spout if it is a set-mount and slide off the pipe. If it a screw-on style, unscrew the spout from the threaded pipe, using a pipe wrench.

  2. Paint joint compound around the outer edge of the pipe.

  3. Slide the new faucet over the pipe, fitting firmly against the wall. If it is a set mount, tighten the screw until it is firmly attached. If it is a screw-on, screw the faucet over the pipe. Tighten the screw-on type using water-pump pliers that have been covered with cloth or tape to prevent scratching.

  4. Run silicone caulk around the edge where the spout butts up against the wall.

  5. Warning

    Be careful when removing the old spout as not to bend or damage the pipe or nipple.
