Fast, Reliable Bathroom Remodeling Across Fullerton
A full bathroom remodel in Fullerton typically runs $9,000-$28,000, with smaller projects like tub-to-shower conversions starting around $3,500. The price moves based on what we find behind the walls, whether the house is a 1920s Craftsman near downtown or a 2000s build in Amerige Heights, and if the lot sits in the former oil-field zone off Bastanchury. We’re Barrett & Sons Construction, led by Tom Barrett, and we’ve been remodeling Fullerton bathrooms long enough to know which permit questions get asked before the first tile comes off. Call (877) 610-1318 for a free estimate and a straight answer on what your specific bathroom will cost.
Why Barrett & Sons Construction Is Fullerton’s Preferred Bathroom Remodeling Company
Fullerton homeowners hire us because we answer our own phone and our name is on the truck. Tom Barrett founded this company in 1998, and his sons run the crews you’ll see in your bathroom. That’s not marketing copy; that’s who shows up.
We know the difference between a 1920s bungalow in the Historic Downtown core and a ranch-style tract home east of Harbor Boulevard. Each comes with its own set of surprises, and we’ve opened enough walls in both to know where they hide. Our crew members are background-checked and uniformed, and every job gets permits pulled and inspections signed before we call it done.
When you call (877) 610-1318, a live person answers, 24/7. Not a call center. Not a voicemail box. You’ll get Tom or someone who works directly with him.
Our Bathroom Remodeling Services in Fullerton
Full Bathroom Remodeling
We gut and rebuild bathrooms from the studs out, whether that stud is a 1918 redwood timber or a 2015 Douglas fir. A full remodel in Fullerton means new waterproofing, new plumbing rough-in where needed, new electrical, new tile, new fixtures, new vanity, new everything. The permit inspector signs off on our work, and the 90-Day Done Right Promise is on paper before we start.

Walk-In Showers & Shower Remodeling
Walk-in showers are the single most requested upgrade in Fullerton’s older homes, because a 1960s fiberglass tub/shower surround with a low curb simply doesn’t work for aging knees. We install frameless glass enclosures, custom tile, built-in niches, and barrier-free curbs where the subfloor allows. In hillside homes in 92835, we pay special attention to slope and drainage; in slab-on-grade ranch houses, we verify the existing drain centerline before ordering any pan.

Tub-to-Shower Conversion
This is the project that saves the most square footage in a small Fullerton bathroom. We pull the old tub, reframe where the wall needs it, relocate the drain if the joist layout allows, and set a walk-in shower in its place. In Fullerton’s northwest quadrant, a tub-to-shower conversion on a slab can trigger methane vapor testing requirements we’ll walk you through before work begins. More on that below.

Vanities, Tile & Fixtures
Sometimes the bones of a Fullerton bathroom are fine and the finishes are what’s tired. We replace vanities, re-tile floors and shower surrounds, swap out valves and trim kits, and install new lighting. We carry named brands you can look up: Kohler, Moen, Delta, and others. No mystery brands off a van.

Trusted Brands We Service in Fullerton
We install fixtures and finishes from brands Fullerton homeowners ask for by name, including Kohler, Moen, Delta, and Cambria when the project calls for it. If you’ve got a warranty issue with a builder-installed Moen valve or a Delta cartridge that’s already failing, we can source the right replacement fast because we stock common parts and know the local supply houses in north Orange County. We don’t make you wait two weeks for a trim kit that’s sitting on a shelf in Placentia.
Common Bathroom Remodeling Problems We See in Fullerton Homes
- Methane vapor testing in the northwest. Homes built over the former Coyote Hills oil field can be flagged by the city for methane soil-vapor assessment when a remodel touches the slab. We handle the testing, the reporting, and the sub-slab barrier install if it’s required.
- Notched and undersized framing in mid-century builds. In 1950s and 60s ranch homes, we regularly find load-bearing studs notched or drilled for plumbing rough-ins with no inspection record. We reframe properly and pull a permit for it.
- Unreinforced masonry in downtown bungalows. A 1920s Craftsman bathroom near the Historic Downtown core may sit on walls that don’t meet current seismic standards. We check for URM and sagging subfloors before we set tile, so you don’t get cracked grout and a failed inspection.
- Non-standard drain rough-ins in master-planned communities. Builder-grade bathrooms in Amerige Heights and similar developments often have drain centerlines that don’t match off-the-shelf shower pans. If we don’t verify the centerline first, you’ll get a change order. So we verify first.

FAQs - Bathroom Remodeling in Fullerton
Yes. Fullerton’s northwest quadrant sits over the former Coyote Hills oil field, and the city regularly flags bathroom remodels that touch slab foundations for methane vapor assessment. The testing itself runs a few hundred dollars; if mitigation is required, the sub-slab barrier and venting add $2,000-$6,000 to the project. We’ve handled this on multiple Fullerton jobs and know how to phase the work so testing doesn’t stall your timeline.
No. If your community has an HOA with architectural review authority, changing a tub to a shower is almost always classified as a modification that needs written approval first. Skipping that step can trigger a stop-work order and a fine from the HOA. We help Fullerton homeowners prepare the submittal, and we’ve done enough of them to know what the review boards want to see. Call (877) 610-1318 if you want help getting yours through.
The shower valve and the tub/shower surround. Builder-grade valves are often plastic-bodied and fail early; the fiberglass surrounds look dated fast. In a typical Fullerton builder home, replacing the tub/shower with a tiled walk-in and a Moen or Kohler valve gives you the most daily use value for the money before you touch the vanity or floor. The vanity can wait. The plumbing behind the wall can’t.
Have a state-licensed contractor pull permits, keep the original fixtures and trim if the builder asks for them back, and document everything in writing. If your builder’s warranty is still active, get written confirmation from the builder or warranty company before we remove any covered component. We’ll provide the written scope they ask for, and we’ll coordinate with their inspector if one is required.
Frequently, yes. Homes in Fullerton’s Historic Downtown core were built before seismic codes existed, and many have unreinforced masonry walls or sagging subfloors under old bathrooms. We check for both before we tile, and if we find problems, we bring the structure up to current code before any finish work goes in. The permit inspector works for you, not for us, and that’s how we like it. Call (877) 610-1318 for an exact quote on your bungalow.
