Shower & Bathtub Plumbing in Fountain Valley, CA
Most shower plumbing hides behind tile, so it pays to do it right once. We replace scaled valves, fix diverters and drains, and handle the plumbing side of bathroom updates.
Showers and tubs hide most of their plumbing behind tile and walls, which is why problems here are worth handling properly the first time. We repair and replace shower valves, fix diverters and drains, and handle the plumbing side of tub and shower updates, all with an eye on the hard water that wears these parts out.
Shower and tub valve work
The mixing valve behind your shower handle controls temperature and flow, and it is the part that fails most. In Fountain Valley's hard water, valve cartridges scale up and start to stick, drip, or lose the ability to hold a steady temperature, the cause of that annoying swing from warm to scalding when someone runs the kitchen tap. We replace worn cartridges and, where needed, the whole valve. On older two-handle setups we can upgrade to a modern anti-scald pressure-balancing valve that keeps the temperature steady and adds a real safety margin.
Common shower and tub problems
Temperature swings and drips
A scaled or worn mixing valve cartridge. Replacing it restores steady temperature and stops the drip.
Weak shower flow
Hard-water scale clogs showerheads and the valve. Cleaning or replacement brings the flow back.
Diverter that will not hold
The tub spout or diverter that sends water up to the showerhead wears out and lets water run from both. A straightforward repair.
Slow or clogged tub drains
Hair and soap, sometimes over a scaled older drain. We clear it and service the stopper mechanism.
Updates and conversions
When you are updating a bathroom, the plumbing behind the walls matters as much as the tile in front of them. We handle the plumbing side of tub-to-shower conversions, valve and trim upgrades, and new shower pans and drains, coordinating with your tile or remodel work so the rough plumbing is right before anything is closed up. Getting the valve height, drain location, and connections correct at the rough-in stage is what prevents problems once the wall is finished.
Behind-the-wall done right
Because shower plumbing lives inside the wall, access and sound workmanship are everything. We make clean access where needed, use quality valves and proper connections, pressure-test before closing up, and leave the opening ready for tile or a panel. The goal is simple: do it once so the wall does not have to come back open.
What shower and tub work costs
A cartridge replacement or drain service is a modest job. A full valve replacement that requires wall access, or the plumbing for a tub-to-shower conversion, is more involved and priced to the scope. After we see the setup, you get a firm written price, and we will tell you honestly whether a repair will hold or the valve has reached replacement.
Frequently asked questions
Why does my shower water temperature keep changing?
Usually a worn or scaled mixing valve cartridge. In Fountain Valley's hard water, these scale up and lose the ability to hold a steady temperature, which is why the water swings when another fixture runs. Replacing the cartridge, or upgrading to an anti-scald valve, fixes it.
Can you fix a dripping shower?
Yes. A dripping shower is typically a worn valve cartridge, scaled up by hard water. We replace the cartridge or, on an older valve, the whole assembly to stop the drip and restore steady operation.
Why is my shower flow weak?
Hard-water scale clogs the showerhead and can restrict the valve. Cleaning or replacing the showerhead often restores the flow. If it persists, the valve itself may be scaled and need service.
Can you handle a tub-to-shower conversion?
We handle the plumbing side: relocating and setting the valve, drain, and connections, and coordinating with your tile or remodel work. Getting the rough plumbing right before the wall is closed is what prevents problems later.
Should I upgrade to an anti-scald valve?
If you have an older two-handle setup that swings in temperature, it is worth considering. A modern pressure-balancing anti-scald valve holds a steady temperature and adds a safety margin against sudden scalding. We can upgrade it during valve work.
