Shower Faucet & Valve Repair in Phoenix
A shower that drips, runs lukewarm, or fights you at the handle almost always comes down to the valve or cartridge behind the wall. Simon repairs and replaces shower faucets, cartridges, and full valves — cleanly, through the existing trim wherever possible — so the fix holds instead of returning in six months.

Common problems Simon fixes
Dripping after the handle is off
A shower head that keeps dripping means the valve or cartridge is letting water past — the shower version of a running toilet, and just as wasteful.
Stiff, loose, or spinning handles
Handles that grind, stick, or spin without changing the water are worn cartridge splines — repairable before the valve fails completely.
Temperature that won't hold
Showers that swing hot-cold when a toilet flushes need a pressure-balancing cartridge or valve doing its job again.
Weak flow from the shower head
Scale in the valve body or a failing cartridge chokes flow long before the shower head itself is the problem.
Water stains on the wall behind the shower
Moisture on the other side of the shower wall can mean the valve is leaking inside the wall cavity — worth diagnosing quickly.

Describe the symptom and the handle style — a photo of the trim helps identify the valve.
Diagnose behind the trim
Most cartridge and valve work happens through the existing opening, keeping your tile intact.
Repair or replace the valve
Cartridges and seals are swapped where the valve is sound; failed valve bodies are replaced properly, positioned for the trim you have.

Frequently asked questions
How much does shower valve replacement cost in Phoenix?
It depends on the valve type and access behind the wall. Simon quotes the full job upfront after seeing the shower, and the price he quotes is the price you pay.
Can you fix my shower without tearing out the tile?
Usually yes. Cartridge swaps and most valve repairs happen through the existing trim opening. Where a full valve replacement needs more access, Simon tells you exactly what's involved before anything is opened.
What is a shower cartridge, and why does mine keep failing?
The cartridge is the moving part inside the valve that mixes hot and cold. Phoenix's hard water scales them up and wears the seals — the reason dripping showers and stiff handles are so common here.
My shower runs lukewarm — is that the valve?
Often, yes. Pressure-balancing valves and cartridges lose their ability to hold temperature as they wear. It can also be a water heater issue; Simon diagnoses which before recommending anything.
Do you replace complete shower faucet sets?
Yes — handle, trim, and the valve behind the wall, matched so everything works and looks right together.
