Shower Repair & Replacement
Bay Area's #1 Choice

A standard shower repair, such as a valve cartridge replacement, typically costs between $200 and $500. For a full replacement, a prefabricated unit installation ranges from $3,000 to $6,000, while a custom tile shower installation in the Bay Area generally starts at $8,500 and can exceed $15,000 depending on materials and waterproofing complexity.

This is usually caused by a failed shower pan, a degraded drain seal, or a breach in the waterproofing liner. If the leak only occurs while the shower is running, the issue is likely the drain assembly or the pan. If it leaks constantly, it points to a pressurized supply line failure behind the wall.

This "thermal shock" is caused by a failing pressure-balancing valve. These valves are designed to maintain a consistent temperature even when other fixtures (like a toilet flushing) draw water. When the internal diaphragm or cartridge wears out, it loses the ability to regulate the mix, requiring a cartridge replacement.

Most high-quality shower valves last 10 to 15 years. Mineral buildup from hard water is the primary cause of premature failure, leading to stiff handles, drips when the shower is off, or inability to reach a specific temperature. Replacing the internal cartridge can often extend the life of the valve body.

Yes, if there is an access panel behind the shower (usually in a closet or hallway). If no access exists, we can often replace the internal cartridge through the front by only removing the handle and trim plate. If the entire valve body is corroded and needs replacement, a small "renovation cover plate" can sometimes be used to avoid extensive tile work.м

If pressure is only low at the shower, the culprit is usually a clogged showerhead aerator or a scaled-up mixing valve cartridge. Mineral deposits restrict the flow over time. We start by descaling the head; if flow doesn't improve, we inspect the valve for internal blockages.

Key indicators include persistent mold in the floor grout, "spongy" spots in the shower floor, or water stains on the baseboards outside the shower. Cracks in a fiberglass base or a leaking lead/vinyl liner under a tile floor are structural failures that require a full pan replacement to prevent subfloor rot.

If the issue is limited to fixtures (faucet, head, or handle), repair is the better value. However, if the tiles are loose, the grout is missing, or the pan is leaking, these are signs of systemic waterproofing failure. In 2026, replacing the unit with modern waterproofing systems offers better long-term protection against mold and structural damage.

A pressure-balanced valve reacts to changes in water pressure to prevent scalding. A thermostatic valve allows you to set a specific temperature and maintains it precisely regardless of pressure changes. Thermostatic valves are more complex and expensive but offer superior comfort and safety.
