What Is Inside the Wall Matters Most
Shower and bathtub installation in Mission Viejo, CA is mostly work you never see again. The valve behind the wall, the drain below the floor and the waterproofing under the tile are what keep a bathroom dry. A pretty shower on a failing pan still leaks.

| Part | What it does | What fails |
|---|---|---|
| Mixing valve | Blends hot and cold and sets the temperature | Worn cartridge, so water drips or temperature swings |
| Drain and trap | Carries water away and blocks sewer gas | Hair clogs, loose connections and cracked seals |
| Pan or base | Catches water under the shower floor | Cracks or a failed liner, so water leaks below |
| Supply lines | Bring hot and cold water to the valve | Corrosion and loose connections |
| Overflow (tub) | Prevents a tub from overfilling | A failed gasket, so water leaks below |
Common Shower and Tub Problems
- A dripping showerhead or tub spout, usually a worn cartridge or diverter.
- Temperature that swings when another fixture runs, which points to the valve or a failing balancing part.
- Slow drains, usually hair and soap in the trap.
- Water stains on the ceiling below a bathroom, which suggest a leak at the drain, valve or pan.
- Loose or cracked tile and soft grout, which can mean water is getting behind them.
A stain below a bathroom should be checked fast. A hidden leak can rot framing and grow mold before it shows. See leak detection and water damage restoration.
Choosing a Showerhead
EPA WaterSense says showering accounts for nearly 17 percent of residential indoor water use. Standard showerheads use 2.5 gallons per minute, and WaterSense labeled ones use no more than 2.0. The EPA estimates an average family could save 2,700 gallons a year by switching.
Hot water use matters as well. Using less water also means heating less, and EPA estimates more than 330 kilowatt hours of electricity saved per year for a household. The savings depend on how many showers you take and how hot you run them.
In hard water, scale clogs the small nozzles in a showerhead. Moulton Niguel's water is near 16 grains per gallon, so soaking a showerhead in vinegar now and then keeps the flow even.
How a New Shower or Tub Is Installed
Rough in the plumbing
The old fixture is removed. The valve, drain and supply lines are set at the right height and tested for leaks before walls are closed.
Waterproof and set the base
The pan or the tub is set level, the drain is connected and the surround is waterproofed. A flood test shows whether it holds water.
Finish and test
Trim, showerhead and spout are installed. The plumber checks temperature, flow and drain speed.
Tile, glass and finish carpentry are often done by other trades. Ask who coordinates the schedule so the plumber is not waiting for a wall or the tile setter for a valve.
Repair or Replace, and What It Costs
- A cartridge, a diverter or a drain is a repair. A cracked pan or a failed liner is a rebuild.
- Access to the wall behind the valve, from a closet, a hall or the next room, changes the work.
- Fixture choice, such as a freestanding tub, a walk-in shower or a tub-to-shower conversion.
- Waterproofing and tile scope.
- Permits for a change in layout or new plumbing.
