It's worth getting quotes from several plumbers to get an idea of the hourly rates in your area so you know how much you can expect to pay. While it's possible to do the job yourself, installing the valve is a moderately skilled job, so it's worth hiring a plumber if you don't have a lot of experience.

How Long Do Shower Valves Last?

The shower valve assembly is a simple part that controls water pressure. Shower valves themselves don't really have a lot of moving parts. How long your valve will last depends on the type of shower you have, how hard your water is and whether the valve is a brass one or one with a cartridge.

The job of the shower valve is to control the water pressure. If the shower valve is installed incorrectly or the cartridge is worn, you may notice water coming out of your tub faucet at the same time as the shower is running. The water pressure out of the showerhead may not be as powerful as you’d expect.

A properly installed shower valve should serve you well for a long time. Even if you live in an area with hard water that causes limescale build-up in your appliances, you can expect to have a shower valve work well for about four or five years.
