Toilet, shower, sink, tub.
We handle it all.

Your bathroom is one of the hardest-working rooms in the house, so when something is off it is good to get it handled. From a running toilet you have been meaning to deal with to a leaking shower valve, we take care of every bathroom plumbing job, including repair, replacement, and new installation, and we are happy to explain your options.

Common bathroom calls

What we fix most often.

  • Running, leaking, or weak-flushing toilets: usually a flapper, fill valve, or wax ring
  • Shower valve repair or replacement when the cartridge fails or temperature controls go bad
  • Tub/shower drain unclogging: typically hair and soap scum; we cable it out
  • Sink and faucet replacement: drop-in, undermount, vessel, wall-mount
  • Slow drains: sometimes simple, sometimes a sign of a bigger drain line issue
  • Leaks under the sink or behind the wall
What we look for

A bathroom leak rarely starts where you see it.

Water travels. A stain on the ceiling below a bathroom can come from a toilet wax ring, a shower valve inside the wall, a cracked drain fitting under the tub, or a supply line that has been weeping for months. We find the source before we fix anything, so you pay to repair the cause, not the symptom.

Inland Empire water is hard, and that shows up in bathrooms first: mineral crust on showerheads, cartridges that stick or drip, and toilet fill valves that stop shutting off. A lot of what looks like a broken fixture is scale, and we tell you when a cleaning or a single part is all it needs.

How a visit goes

Clear options, and your bathroom left clean.

  • We find the real problem: we test the fixture, the shut-offs and the drain, and show you what we found
  • You get options in writing: repair or replace, with a flat-rate price for each, before any work begins
  • We protect the room: drop cloths down, fixtures handled with care, and the work area cleaned up when we finish
  • We label your shut-offs: every shut-off we find gets labeled, so you know which valve to close next time
  • We patch what we open: if we have to open drywall to reach a leak, we patch it
Call right away if

Some bathroom problems can't wait.

  • Water on the floor you can't stop: close the shut-off behind the toilet or the main water valve, then call
  • A toilet that keeps overflowing: turn the valve behind the toilet clockwise until it stops turning, and don't flush again
  • Sewage coming up in the tub or shower: this usually means the main line is blocked; stop running water anywhere in the house, then call
  • A stain spreading on the ceiling below: stop using that bathroom and call, because water is getting into the structure now

Common Questions

Frequently asked questions.

Why does my toilet keep running?
Most of the time it is the flapper or the fill valve. A worn flapper lets water leak from the tank into the bowl, so the tank keeps refilling. Hard water also wears out fill valves. Both are common, simple repairs, and we will tell you if the toilet itself is worth keeping.
My shower drips after I turn it off. What is wrong?
Usually the valve cartridge behind the handle is worn or crusted with minerals from hard water. Replacing the cartridge often fixes it without opening the wall. If the valve body itself is failing, we explain your options before any work starts.
Can you fix a leak behind the wall without tearing out the whole shower?
Often, yes. We locate the leak first, then open only what we need to reach it. If we open drywall to make the repair, we patch it.
Why is the floor around my toilet wet?
The most common cause is a failed wax ring under the toilet, which lets water seep out each time it flushes. It can also be a leaking supply line or tank bolts. A wet floor around the toilet can damage the subfloor, so it is worth fixing early.
Do you take bathroom calls in Spanish?
Yes. Call (909) 312-4516 and we can help you in Spanish. Texts in Spanish to (909) 247-6791 are answered too, 8 a.m. to 8 p.m.
