Shower Valve Replacement in Phoenix, AZ — A New Valve That Holds Temperature

Some shower valves are too old or too corroded to rebuild, and parts for many older models are simply gone. Replacing the valve body gives you a modern pressure-balancing valve that holds temperature when a toilet flushes. We plan the access with you before we open anything.

When You Need Shower Valve Replacement

Replace the valve when the body is corroded or cracked, when parts are discontinued, when the valve leaks inside the wall, when a rebuild only lasted a few months, or when you are remodeling the shower and want a new trim style.

Older two-handle and non-balancing valves also allow scalding temperature swings, which is a real safety issue in homes with kids or older adults. A new pressure-balancing or thermostatic valve solves that along with the leak.

Our Shower Valve Replacement Process

We locate the valve and plan access, ideally from a closet or wall behind the shower. When access has to come through tile, we cut the smallest opening we can and tell you exactly where it will be, plus what the tile repair will involve.

We shut off water, cut out the old valve body, install a new pressure-balancing valve with proper soldered or PEX connections and a mounting brace, then pressure test before the wall closes. We set the trim, adjust the hot limit stop, and run the shower while checking for leaks and temperature stability. Most replacements take three to five hours, or longer if tile work is involved.

Shower Valve Replacement Cost in Phoenix

Replacement price depends on the valve chosen, how we reach it, whether tile or drywall has to be opened, and the plumbing material in the wall. You always get a flat price in writing before any work starts, so nothing changes at the end. There is no trip fee, and we do not charge extra for evenings or weekends. If we open things up and find more damage, we stop, show you what we found, and let you decide. Call 602-842-2344 and we will explain what your job will likely involve.
