Shower Valve Replacement in Denver, CO
A shower valve that scalds when a toilet flushes, will not shut off fully, or drips into the tub all night is worn out. Unlike a faucet, this valve lives inside the wall, so the job is about access as much as plumbing.
- Pressure balance and thermostatic valves installed
- Access through the back wall when possible to save tile

What it is
Shower valve replacement Shower valve replacement is the removal and replacement of the mixing valve inside a shower wall that controls water temperature and flow to the showerhead.
Denver's hard water accelerates mineral buildup inside shower valve cartridges, which is a common cause of a shower that will not get hot, will not shut off fully, or has wildly swinging temperature.
Scalding when someone flushes means the valve is not balancing
Modern code requires a pressure balance or thermostatic valve that holds temperature when cold pressure drops. Old two-handle and non-balancing valves do not, which is why a flush turns a shower hot. Replacing the valve is the fix, not adjusting the handle.
- Pressure balance valves hold temperature during pressure swings
- Thermostatic valves hold an exact set temperature
- Cartridge-only repair when the valve body is still sound
- Access panel option that avoids tearing out tile
Replace the shower valve when
- Water scalds when another fixture runs
- The handle no longer shuts the flow completely
- Temperature swings on its own mid-shower
- The diverter will not hold water at the shower head
- Parts for the valve are discontinued
What the job involves
- Identifying the valve brand and whether a cartridge swap will solve it
- Access plan: through a back wall closet when possible, tile only when necessary
- New pressure balance or thermostatic valve body soldered or pressed in
- Rough-in depth set correctly for the finished wall and trim kit
- Pressure test before the wall closes
- Trim, escutcheon, and handle installed and sealed
