Replace A Tub Shower Faucet
You can replace or install a combination tub shower faucet yourself and save money, but first you must remove the old shower control valve. Shower control valves are produced by a lot of different manufactures and each have specifics that must be followed. Following the manufacturer instructions or directions can help you save time, money and effort. It can also help you end up with a neater, more satisfactory installation. Combination tub shower faucet are available in a variety of designs that include single-handle, dual-handle and three-handle so you need to read directions.
The first challenge in installing bath and shower faucets is removing the faucet assemblies behind the wall. Most home builders provide a rear access panel behind the shower wall, if you do not find one you may need to make your own.

Removing old tub shower faucet
- Try to locate a access panel most home builders provide a rear access panel behind the shower wall. If you do not find one you may need to make your own it may be easier going throw the shower wall unless you are planning to remove the old tub surround or tile.
- Shut the water off to your shower. Most showers do not have individual shut-off valves, so you may need to turn the water supply off where it enters your home. If you know where shut-off valves are that lead to just your bathroom, that will work as well.
- Turn your faucet handles on to drain the water from the shower fixture. This will help you see if the water is properly shut off.
- Protect your tub or shower floor. Place a thick towel on the bottom of the shower or tub to protect the surface from damage if a tool happens to drop. This also prevents parts of the shower faucet from falling into the drain.
- Pop off the cap on the handle using a small flathead screwdriver than remove the screw under the cap and pull off the handle.
- Remove any caulking or silicone around the metal plate and pull it away from the wall.
- Now go to the access panel and remove any water line to the water valve, including the shower head and the tub spout. Than remove any screws holding the shower valve in place.
Installing new tub shower faucet
- Combination tub shower faucet control valves are produced by a lot of different manufactures and each have specifics that must be followed. All plumbing manufacturers do things a little differently, so the best thing you can do is to read, understand and follow step by step the proper installation or directions for the specific brand that you have.
- There are a few things that all faucet have in common like making sure that the shower control valve is mounted on a support brace at the correct distance from the finished wall. Use copper pipe for the bathtub spout even if your using pex for the rest. The high of the shower valve should be about 12 inches above the top of the tub.
- Shower faucets are available in a variety of designs that include single-handle, dual-handle and three-handle. Whether the shower faucet is a single, dual or three-handle design, the installation process is the same. The depths for each rough valve are critical, if the valve is set too deep, or too shallow then the finish trim won't fit and something will need to be torn up to get at the valves again.
- To get the depths perfect you need to know the thickness of the backer board and the tile or tub surround. When you have the exact depth to install the rough valves you can put a wood blocking behind the valve to have something to attach it to that is solid.
- The tub spout should be about 4 inches above the top of the tub. Make sure you put a wood blocking behind the tub spout to have something to attach it to that is solid.
- The standard height for the shower head is between 75 and 82 inches from the floor height, also use wood blocking behind the shower head to have something to attach it to that is solid.
- I like to put a hot and cold water shut off vale on the water lines just before the shower valve. But the shut off valves are optional, if you do use them make sure you have a access door.
- Reconnect all of you water lines turn on the water and check for leaks.
