What’s happening with your bathroom plumbing?
Tap the closest match for a quick plain-English read and your next step. It is a guide, not a diagnosis.
Common Bathroom Plumbing Problems
Slow or gurgling drains, dripping fixtures, weak water flow, running toilets and damp walls account for most calls. Many share one cause, such as mineral buildup from San Antonio’s hard water or a worn connection, so we diagnose first instead of swapping parts.
Shower and Bathtub Plumbing
We repair leaking shower arms, tub spouts, drains and overflow assemblies, and replace corroded fittings. If the valve itself is failing, our Shower Valve Repair team handles cartridges, diverters and temperature control.
Bathroom Sink and Vanity Connections
Leaks under the vanity usually come from loose compression nuts, cracked P-traps or aging supply lines and angle stops. We replace the worn part and test every joint under pressure.
Bathroom Drain and Supply Pipe Repairs
We repair or replace damaged drain lines, supply pipes and shut-off valves, and clear persistent backups. Older galvanized or corroded lines are explained plainly so you can decide between repair and replacement.
Leaks Behind Bathroom Walls
Hidden leaks cause mold, stained ceilings and surprise water bills. We pinpoint the source, open only what is needed and explain the repair before cutting. Moisture left behind can keep damaging wood, so we do not paper over it.
Bathroom Plumbing Installation
Adding a bathroom, moving a vanity or fitting a new tub or shower needs correct supply, drain and vent layout. We plan it to code and coordinate with remodel crews; see Bathroom Remodel Plumbing for full renovations.

Bathroom Plumbing FAQs
Why do bathroom drains back up?
Hair, soap scum and mineral buildup narrow the drain over time. If the tub, shower and toilet all back up together, the blockage is usually further down the main line and needs a camera or professional cleaning, not just a plunger.
Can a plumber repair a leaking shower?
Yes. Most shower leaks come from a worn cartridge, failed seal, loose fitting or a leaking drain connection. We locate the source, show you what failed and repair or replace only what is necessary.
When should bathroom pipes be replaced?
Consider replacement when pipes show repeated leaks, green or white corrosion, discolored water or reduced flow. We give you repair and replacement options with written pricing so you can compare.
How do I find a hidden leak in my bathroom?
Turn off all water and watch your meter. If it still moves, there is a leak somewhere. Stained ceilings below a bathroom, musty smells and warped flooring are other signs. We can pinpoint it without guesswork.
