San Francisco service
Shower and tub valve repair in San Francisco.
Lutz Plumbing repairs and replaces shower and tub valves in San Francisco. We fix showers that drip after they are turned off, water that turns hot or cold without warning, tub spouts that keep running when the shower is on, stiff handles, and valves leaking inside the wall, on standard and designer valves alike.
What this service includes
- Dripping shower heads and tub spouts: cartridge and seal replacement
- Sudden hot or cold water: pressure-balancing and thermostatic valve repair
- Diverters that will not send water to the shower head
- Stiff, loose, or broken handles and trim
- Valve replacement from the front or through an access panel where possible
- Leaks inside the wall located before any wall opening is recommended
Shower valve repair in San Francisco, starting with the cartridge.
Most shower problems start inside the valve body behind the handle. A worn cartridge or seal causes a drip that will not stop, a failing pressure-balancing or thermostatic cartridge causes sudden temperature swings, and a worn diverter keeps water running from the tub spout when the shower is on. Lutz Plumbing identifies the valve's make and model, then replaces the failed part rather than the whole valve when the valve body is sound.
When the valve body itself has failed, is corroded, or is a discontinued design with no parts, we replace it. A replacement shower valve must be a pressure-balance, thermostatic, or combination type under the California Plumbing Code, and we plan the work around the finished wall: from the front through the trim opening where the valve allows it, or from an access panel or the wall behind. If water is showing up on a ceiling or wall below the shower, start with leak detection.
- The shower drips after it is turned off: a worn cartridge, stem, or seal inside the valve.
- Water turns hot or cold when someone flushes a toilet: the pressure-balancing or thermostatic cartridge is no longer compensating.
- Water keeps coming out of the tub spout with the shower on: a worn diverter in the spout or the valve.
- The handle is stiff, loose, or turns without changing anything: a worn cartridge, a stripped stem, or broken trim.
- Water stains below the bathroom: a leak at the valve body or its connections inside the wall, located before any wall opening is recommended.

Common questions
Why does my shower keep dripping after I turn it off?
A shower that drips after it is turned off almost always has a worn cartridge, stem, or seal inside the valve. Replacing that part usually stops the drip without replacing the valve. Lutz Plumbing identifies the valve's make and model and replaces the worn part in San Francisco homes and buildings.
Why does my shower suddenly turn hot or cold?
A shower that turns hot or cold when another fixture is used usually has a pressure-balancing or thermostatic cartridge that has stopped compensating for pressure changes. Repairing or replacing that cartridge restores the anti-scald protection. If the temperature swings at every fixture, the cause may be the water heater instead, and Lutz checks both.
Why is water coming out of the tub spout when the shower is on?
Water that keeps running from the tub spout with the shower on means the diverter is worn. Depending on the design, the diverter is in the spout itself or in the valve, and replacing the spout or the diverter cartridge usually fixes it.
Can a shower valve be replaced without removing tile?
Often, yes. Many valves can be repaired from the front by replacing the cartridge, and some can be replaced through the trim opening or from an access panel or the wall behind. When the valve body has failed and the only access is through the tiled wall, Lutz explains the options before any tile is touched.
Do you repair designer and older shower valves?
Yes. Lutz Plumbing works on standard and designer shower valves, and Lutz Bath & Kitchen, the fixture showroom in the same building, works directly with manufacturers when a part is hard to find. When an older valve has no parts available, we recommend a replacement that fits the existing trim and wall where possible.
Is a leaking shower valve an emergency?
A drip from the shower head is not an emergency, but a leak inside the wall can damage the ceiling, floor, or unit below. If you see water stains or active dripping below a bathroom, stop using the shower and call. Lutz locates the leak before recommending any wall opening, and you get a written quote before the work starts.
