New shower valves installed for steady temperature, smooth control, and reliable, leak-free performance behind the wall.
Shower valve installation covers replacing or installing the mixing valve that controls your shower's temperature and flow. Flat Rate Plumbing Company installs the new valve, makes the behind-the-wall connections, sets the pressure balance, reinstalls the trim, and tests the temperature and flow before finishing.
This is real plumbing, not a fixture swap — the valve lives inside the wall, and the connections have to be watertight because they're not easy to reach again. It's exactly the kind of work where having a master plumber matters.
Roy Adams has been a licensed Texas Master Plumber since 1984 and installs shower valves throughout Grand Prairie, Arlington, Cedar Hill, Mansfield, and Duncanville — with one upfront flat-rate price approved before he begins.
Behind-the-wall to finished trim, here's what's included.
A new shower mixing valve installed and connected.
Pressure-balanced setup for safe, steady temperature.
Watertight supply connections made inside the wall.
Trim reinstalled and temperature and flow tested.
A shower valve controls both comfort and safety — a pressure-balanced valve keeps the water from suddenly going scalding when someone flushes elsewhere. And because the valve and its connections are sealed inside the wall, a sloppy connection means a hidden leak that can rot framing and feed mold before you ever see it.
Roy makes the connections properly, sets the balance, and pressure-tests the valve before the wall goes back — so you get steady temperature and no surprises behind the tile.
It's one upfront flat-rate price, so you know the cost of the job before it begins.
When it's done, your shower holds its temperature and the connections are solid:

Yes. That swing is the classic sign of an old valve without pressure balancing. A modern pressure-balanced shower valve holds your temperature steady even when another fixture is used, and it's a real safety upgrade against scalding.
It depends on the setup. Many valves can be accessed and serviced through the front, but a full valve replacement sometimes needs access behind the wall. Roy will explain exactly what your job requires as part of the upfront flat-rate quote — no surprises.
