We've broken our bathroom plumbing services into the four work types Orange County homeowners call us for most. If you don't see what you need below, call us anyway. There isn't a bathroom fixture or supply problem we haven't already seen and fixed somewhere in OC.
Some bathroom plumbing problems announce themselves loudly. A flooded floor doesn't need an explanation. Others quietly cost you money or set up a bigger failure later. If you notice any of these in your Orange County home, it's time to call a bathroom plumber:
If two or more of these are happening in the same bathroom, the problem is rarely just one fixture. Call (949) 492-0137 and we'll diagnose the whole room in one visit.
We hear the same thing from new customers about the plumber they used before us: they didn't know what the bill would be until the work was already done. We won't do it that way. Here's exactly what happens when you call Doheny Plumbing for a bathroom job in Orange County:
A licensed Doheny plumber arrives in a marked truck, in uniform, usually within two hours of your call (within 30 minutes for declared emergencies). We listen to the symptoms, look at the fixture, run the water, and find the root cause, not just the symptom. If a wall has to come open or a drain camera has to go down, we tell you before we do it.
Before any wrench turns, we hand you a written price for the repair: flat-rate, not hourly, so the cost doesn't grow if the job takes longer than expected. If the fix has more than one option (repair vs. replace, for example), we walk through both and let you choose. No pressure, no surprise add-ons.
We make the repair using parts we stock on the truck. Most bathroom-plumbing calls are one-trip jobs. After the work is done we run the fixture under load (flush the toilet five times, fill the tub, run the shower for several minutes) to confirm there's no leak. Then we wipe down the area, take the old parts and packaging with us, and walk you through what we did and what to watch for.
Most bathroom remodels turn on the plumbing. A contractor can pour new tile and hang a new vanity, but if the rough-in plumbing isn't right, the finished bathroom will leak, drain slow, or fail inspection. Doheny Plumbing handles the rough-in and finish plumbing for full bathroom remodels and smaller upgrades across Orange County, working alongside your contractor or directly with you on a homeowner-led project.
Common remodel work we handle includes relocating a toilet flange, moving sink supplies and drains for a new vanity layout, converting a tub to a walk-in shower (which means a new shower drain, pan slope, and mixing valve), upgrading galvanized supply lines to copper or PEX, and tying in new fixtures so the final inspection passes the first time. We pull the plumbing permits, schedule the rough-in inspection, and come back at trim-out to set the toilets, faucets, and shower trim once the tile and finishes are in.
If you're planning a remodel, the cheapest call you'll make is the one before demo. A 20-minute walkthrough lets us flag whether you have galvanized supply lines, an undersized vent stack, or a drain layout that will make the new design more expensive to build. Call us before you commit to a layout.

Orange County has hundreds of plumbing companies. Most started in the last ten years; a handful of us have been here long enough to have worked on the same houses twice. A few things separate Doheny from the rest, and they're the reasons our customers stay customers across decades.

Doheny Plumbing has been family-owned and operated since the 1980s. Our reputation in Orange County was built one bathroom, one kitchen, and one water heater at a time, not by acquiring smaller companies. The people who answer the phone and dispatch the trucks are the same people whose name is on the trucks.
Every Doheny plumber works under our California state plumbing contractor license (C 36) and General B license (#822233), with current workers' comp and liability coverage. If something goes wrong on a job at your house, our insurance covers it, not yours. Ask any plumber for proof of insurance before they start work in your home; we'll have ours in the truck.
Bathroom emergencies don't wait for business hours. We dispatch a licensed plumber 24 hours a day, seven days a week, including weekends and holidays. Our 30-minute on-site target for declared emergencies (active leaks, overflowing toilets, no-water situations) is one of the fastest in OC. Call (949) 492-0137 any hour and a real person will pick up.
How fast can a bathroom plumber get to my Orange County home?
For declared emergencies (active leaks, overflowing toilets, no-water situations), we dispatch within minutes and target a 30-minute on-site arrival anywhere in our Orange County service area. For non-emergency calls, most same-day requests get a two-to-four-hour window. We confirm the actual ETA when you call us.
What does it cost to replace a toilet, shower valve, or bathroom faucet?
Toilet replacement (standard residential, including a new wax ring, supply line, and haul-away) usually runs $400 to $750 in Orange County, depending on the toilet model. Shower valve replacement (in-wall mixing or pressure-balance valve) is typically $450 to $900 because it's a labor-heavier job. A standard bathroom faucet swap with new supply stops runs $250 to $450. We give every customer a written, flat-rate price before any work starts; these are typical ranges, not your final price.
Do you fix bathroom leaks inside the wall or under the slab?
Yes. We trace in-wall pinhole leaks, supply-line leaks, and shower-pan leaks using non-destructive leak detection where possible (acoustic listening, moisture mapping, pressure tests) so we only open drywall where the leak actually is. For under-slab leaks, we'll determine whether a pinpoint repair, a re-route through the attic, or a full repipe is the most economical fix and quote each option.
Should I repair my old toilet or replace it?
The repair-vs.-replace breakpoint is usually around 25 years old or 3.5+ gallons per flush. Toilets that old were built before low-flow standards and waste roughly twice the water of a modern 1.28-gpf model. If the bowl is cracked, the trip lever keeps breaking, or you've already replaced the fill valve and flapper in the last two years, replacement almost always saves money long-term.
Do you handle bathroom remodel plumbing?
Yes. We do both rough-in work (moving supplies and drains for new layouts, converting tub-to-shower, relocating toilet flanges) and finish work (setting new toilets, faucets, and shower trim after tile and cabinetry are in). We pull permits, schedule the inspection, and coordinate with your contractor so the plumbing doesn't hold up the rest of the project.
Are you licensed and insured?
Yes. Doheny Plumbing operates under California state plumbing contractor license C 36 and General B license #822233, with current workers' compensation and liability coverage. We carry proof of insurance in every truck.
Do you serve all of Orange County?
Yes. We provide bathroom plumbing services across Orange County including Newport Beach, Irvine, Costa Mesa, Huntington Beach, Anaheim, Mission Viejo, Laguna Niguel, Laguna Beach, San Clemente, Dana Point, Aliso Viejo, Lake Forest, Tustin, Orange, Yorba Linda, Fullerton, Santa Ana, Garden Grove, Westminster, and surrounding communities.
