Showers

The parts that matter most are the ones you never see.

Finished tile shower with a rain shower head, handheld sprayer and built-in niche

The parts of a shower that matter most are hidden: the valve, the drain and the waterproofing. AccuFlow provides shower repair in Lodi, Acampo and nearby towns for temperature that swings when someone flushes, a shower head that keeps dripping, a handle that won’t shut off and low pressure. Most of those are fixed by rebuilding or replacing the valve cartridge, usually through an access panel or with as little tile removed as possible. For shower installation, we install new valves, drains, pans and fixtures for replacements, tub-to-shower conversions and new bathrooms.

Shower Valve Repair

Cartridges and valves rebuilt or replaced to stop drips and temperature swings.

Anti-Scald Valve Upgrades

Pressure-balance and thermostatic valves that hold the temperature steady.

Pans, Drains & Leaks

Leaking pans and drains repaired before water reaches the framing.

Tub-to-Shower Conversions

Old tubs out, a new shower pan, valve and fixtures in.

Why your shower goes cold when someone flushes

Older shower valves have no pressure-balance protection, so when a toilet or washer pulls cold water, the shower suddenly runs hot (or the other way around). A pressure-balance valve keeps the hot-to-cold ratio steady and is required on new installs. A thermostatic valve goes a step further and holds an exact temperature. Upgrading the valve is one of the most noticeable improvements you can make to an older bathroom, and it can often be done without redoing the tile.

Signs your shower needs repair

  • Water temperature swings during use
  • The shower head drips after it’s shut off
  • Stains or soft drywall on the other side of the wall
  • Low pressure only at the shower
  • Cracked or loose tile near the floor
  • A slow drain or standing water in the pan

Leaks behind the wall

A shower can leak from the valve, the supply pipes, the drain or failed waterproofing under the tile. Signs show up away from the shower: stains on the ceiling below, soft drywall in the next room or loose tile at the base. We test the valve, drain and pan separately to find which one is leaking, so the repair targets the actual source. See leak detection if the source isn’t obvious.

New showers and conversions

For a new shower or a tub-to-shower conversion, we set the mixing valve at the right depth for your wall finish, install the drain and pan, and pressure test everything before the walls are closed or tiled. Because we also do the tile work, the valve, pan and waterproofing are planned together. Larger projects are covered on our bathroom remodeling page.

What affects the cost of shower work

  • Repair or replace: a cartridge is a smaller job than a new valve.
  • Access: an access panel behind the shower, or tile that has to be opened.
  • Valve type: pressure-balance or thermostatic, and the trim you choose.
  • Pan and waterproofing: a leaking pan means more work than a valve.
  • Conversion scope: removing a tub and building a new shower.

Your valve likely has no pressure-balance protection. Upgrading to a pressure-balance or thermostatic valve keeps the temperature steady.
Often, yes. We work through an access panel or the trim opening, or remove as little tile as possible. Some trim kits are designed to cover the opening.
Look for stains on the ceiling below, soft drywall on the other side of the wall, loose tile or a musty smell. We test the valve, drain and pan separately.
Common causes are a clogged shower head, a worn or scaled cartridge, a flow restrictor, or a partly closed valve. If every fixture is low, the problem is elsewhere in the house.
A worn cartridge or seal is letting water through. Replacing the cartridge usually stops it.
Yes. We remove the tub, install a new pan, drain and valve, and coordinate the tile so it is waterproofed correctly.
