Leaking shower valve, low water pressure, or tub drain problems? We repair and install shower valves, diverters, drains, and tub spouts.
What Is Shower & Bathtub Plumbing?
Shower and bathtub plumbing repair covers the valves, drains, spouts, diverters, and fixtures that control water flow in your shower and tub. Common problems include dripping shower heads, leaking shower valves behind the wall, stuck or broken diverters (the mechanism that switches water between the tub spout and shower head), slow tub drains, and low water pressure from the shower.
Shower valve repair is one of the most frequent bathroom plumbing calls. The mixing valve — a single-handle or two-handle assembly mounted behind the tile or surround — controls water temperature and flow. When the cartridge inside this valve wears out, the shower drips continuously, temperature control becomes erratic, or the handle becomes difficult to turn. Replacing the cartridge requires shutting off the water, removing the handle and trim plate, extracting the old cartridge, and installing a new one matched to the valve brand.
Diverter repair addresses the mechanism that redirects water from the tub spout up to the shower head. Tub spout diverters are built into the spout and wear out over time, causing water to leak from the spout while showering. Wall-mounted diverters use a separate valve handle and may need cartridge or washer replacement.
Tub drain problems typically involve a slow drain caused by hair and soap accumulation, or a failed drain stopper mechanism (trip lever, lift-and-turn, or push-pull type). The plumber clears the drain, tests the stopper mechanism, and repairs or replaces worn components.
In Texas, hard water accelerates wear on shower cartridges and valve seats, making shower valve repair one of the most common service calls in areas with heavy mineral content.
Signs You Need Shower & Bathtub Plumbing
If you notice any of these symptoms, it's time to call a licensed plumber for professional assessment.
- ⚠Shower drips continuously after the handle is turned off.
- ⚠Difficulty controlling water temperature — it swings between hot and cold.
- ⚠Water leaks from the tub spout while the shower is running — the diverter has failed.
- ⚠Low water pressure from the shower head only — the cartridge may be partially blocked.
- ⚠Tub drains slowly despite clearing visible hair — the drain line may need professional cleaning.
- ⚠Water leaking from behind the shower wall or through the ceiling below.
Common Causes and Why This Happens
Understanding what causes the problem helps you make an informed decision about the best repair approach.
Worn shower valve cartridge that no longer controls temperature or stops water flow.
Failed tub/shower diverter that leaks water from the tub spout during showering.
Clogged or corroded shower head restricting water flow and pressure.
Slow or clogged tub drain from hair and soap accumulation.
Cracked or deteriorated grout and caulk allowing water behind the shower surround.
Loose shower handle or trim plate caused by stripped cartridge adapter or set screw.

How Much Does Shower & Bathtub Plumbing Cost in Texas?
| Low | Average | High |
|---|---|---|
| $100 | $275 | $600+ |
Prices vary based on the specifics of each job. We provide a detailed, itemized estimate on site before any work begins — the price you approve is the price you pay.
Factors That Affect Cost
- •Type of repair — cartridge replacement vs. full valve replacement vs. drain work.
- •Valve brand and accessibility — some cartridges are proprietary and must be ordered; wall access may be needed for the valve.
- •Tile or surround condition — if the valve requires wall access, tile removal and restoration add cost.
- •Diverter type — tub spout diverters are replaced with the spout; wall-mount diverters require valve work.
- •Whether the repair is limited to one component or involves multiple fixture issues.
Benefits of Professional Shower & Bathtub Plumbing
Stops constant dripping that wastes water and stains the tub or shower floor.
Restores temperature control — eliminates the dangerous sudden hot/cold swings.
Proper diverter repair keeps water flowing through the shower head instead of leaking from the spout.
Drain clearing eliminates standing water and the mold conditions that thrive in persistently damp showers.
Expert Tip
If your shower handle has become hard to turn or no longer controls temperature smoothly, the cartridge is failing. Replace it before it seizes completely — a seized cartridge is much harder to extract and can damage the valve body, turning a $150 cartridge swap into a $500+ valve replacement.

Shower valve cartridges are brand-specific — a Moen 1222 is completely different from a Delta RP46074 or a Kohler GP77759. We identify the exact valve brand and cartridge model before starting, so the replacement part matches correctly. Using the wrong cartridge causes leaks, temperature problems, and potential damage to the valve body.

Why does my shower drip after I turn it off?▼
The cartridge inside the mixing valve is worn and no longer seals completely. Replacing the cartridge — a 30-60 minute repair — stops the drip.
Can you replace a shower valve without removing all the tile?▼
In many cases, the cartridge can be replaced through the existing trim opening without tile removal. If the valve body itself needs replacement, an access panel behind the wall is the least-destructive approach.
Why does water come from the tub spout when I'm showering?▼
The diverter has worn out. For tub spout diverters, replacing the entire spout resolves the issue. For wall-mount diverters, the cartridge or washer needs replacement.
How do I clear a slow bathtub drain?▼
Remove the drain stopper and clear any visible hair. If the drain is still slow, professional snaking or hydro jetting may be needed to clear buildup further down the line.
Does hard water affect shower valves?▼
Yes. Texas hard water deposits minerals on cartridge seals and valve seats, causing stiffness, dripping, and reduced flow. Cartridge replacement is needed more frequently in hard-water areas.
