Fast, Reliable Bathroom Remodeling Across Union City
A full bathroom remodel in Union City typically runs $9,000 to $28,000, and most jobs take two to five weeks depending on whether you’re moving plumbing, replacing a tub with a walk-in shower, or gutting a small hall bath. If you live in the 94587 zip code, you’re calling someone who already knows what’s under your house, because Union City’s older tract homes were largely built on bay fill and former marshland, and that changes how a remodel starts. Tom Barrett has been running crews in the Bay Area since 1998, and his sons are the ones walking your bathroom with a tape measure. Call (877) 610-1318 and a live person answers, day or night.
Why Barrett & Sons Construction Is Union City’s Preferred Bathroom Remodeling Company
You won’t get a call center. You get Tom Barrett’s name, his license number, and his address in writing, and you can look any of it up before you sign a single page. That matters in Union City, where a lot of homeowners have already been through the phone-quote-to-door-bill routine with a big outfit and aren’t eager to repeat it. We’re the ones who show up in a truck with a name on the side and a crew whose members carry that same name.
We’ve remodeled bathrooms from the Decoto district to the neighborhoods around Alvarado-Niles Road, and the homes there all share the same DNA: single-story stucco-over-wood-frame, concrete slabs poured under seismic codes that predate modern standards. That isn’t a trivia item. It dictates how we address waterproofing, floor leveling, and drain placement before the first tile goes up.
Every job starts with a written scope and written allowances. If anything changes, you get a written change order before a single nail moves. Our 90-Day Done Right Promise is on every contract: if something isn’t done right, one call brings Tom back. And the permit inspector works for you, not for us. That’s the whole point of pulling permits and getting inspections signed on every eligible job.
Our Bathroom Remodeling Services in Union City
Full Bathroom Remodeling
A full remodel in Union City often means rebuilding a bathroom that hasn’t been touched since the house went up in the sixties or seventies. We handle it from demo to final walkthrough: moving walls where it makes sense, replacing aging copper supply lines, leveling floors over slab, and laying out a room that actually fits how you live now. Bathroom Remodeling at this scale is where permits, inspections, and written change orders matter most, because the work touches framing, plumbing, electrical, and waterproofing.

Walk-In Showers & Shower Remodeling
Walk-in showers are the single most requested upgrade we see in Union City, especially in homes where the original tub-shower combo sits in a narrow alcove. In Union City’s older slab homes, we pay close attention to the shower pan and drain height, because a slab with high moisture content from the bay’s shallow groundwater can complicate a curbless design. Expect a walk-in shower installation in Union City to run $4,500 to $12,000 depending on glass, tile, and whether we’re moving the drain.

Tub-to-Shower Conversion
Converting a tub to a shower in Union City usually runs $3,500 to $10,000. It’s the right move for homeowners who want to stay in their house as they get older but don’t want a tub they’ll never climb into again. We’ll walk you through grab-bar blocking, bench height, slip-resistant tile, and the doorway width that makes the shower usable for years, not just right after the job is done.

Vanities, Tile & Fixtures
A vanity replacement in Union City runs $800 to $3,000 for the install, not counting the vanity itself. Tile work ranges widely based on format and layout, and we’ll give you a line-item price before we start, not a round number that drifts. We install the fixtures you pick from real brands you can look up, not whatever was left in the van.

Trusted Brands We Service in Union City
We carry Techo-Bloc for hardscape-adjacent bathroom transitions and Cambridge Pavers where an outdoor shower or entry landing ties into the bath, and we stock the common trim, valves, and spare parts that keep a Union City bathroom remodel from stalling over a small fitting. If you call us about a bathroom that’s half-done by someone else, we’ll tell you honestly what’s salvageable and what isn’t. We also handle Windows & Doors in Union City, which comes up more than you’d think when a bathroom vent or frosted window needs replacing mid-remodel.
Common Bathroom Remodeling Problems We See in Union City Homes
- Slab moisture and cracked shower pans. Union City’s flatlands sit on former bay marsh, and the California Geological Survey maps much of it as a liquefaction hazard zone. Water moves through that soil, and older slab bathrooms often have hairline cracks under the shower pan that aren’t visible until demo. We check before we set tile.
- Galvanized supply lines failing at the wall. Homes built in the 1960s and 70s frequently still have galvanized pipe, and we regularly find it nearly closed off with rust where it meets the shutoff valve. A bathroom remodel is the cheapest time to replace it, while the wall is already open.
- Exhaust fans venting into the attic. It’s code-defeating and it’s everywhere in Union City tract homes. Warm bay air plus a vented bathroom equals mold in the ceiling cavity. We run the duct to the exterior and seal it properly on every full remodel.
- Subfloor rot around the tub lip. The diablo and delta winds off the bay push moisture into exterior walls, and a tub against an outside wall that wasn’t flashed right will rot the subfloor over decades. We’ve seen it in Alvarado and Decoto homes more than once, and the fix starts with real flashing, not caulk.

FAQs - Bathroom Remodeling in Union City
We can typically get you on the schedule within two to four weeks after you sign, depending on permit lead time. Union City’s building department commonly requires a geotechnical soils report as a condition of foundation or structural permit issuance for work in liquefaction hazard zones, and that report can add four to six weeks before a shovel hits the ground. We tell you that timeline up front, not after you’ve moved your stuff out of the bathroom. Call (877) 610-1318 and we’ll tell you what your specific street triggers.
Yes. We work throughout the 94587 zip code, from the older pockets in the Decoto and Alvarado districts to the postwar tract neighborhoods east of Mission Boulevard and the newer sections near the Union Landing area. If you’re within Union City city limits, there’s no trip charge inside the county on a scheduled estimate.
We handle urgent water intrusion and failed shutoff valves, but a bathroom remodel isn’t an emergency job and we won’t pretend it is. If you have water actively leaking into a slab or through a ceiling, we’ll get someone out to stop the loss and then scope the repair properly. A live person answers the phone 24 hours a day, so you won’t be leaving a voicemail while water runs.
In some cases, yes, and for a specific reason: Union City’s flatland neighborhoods sit in California Geological Survey-designated liquefaction hazard zones, which means the building department often wants a geotechnical report before issuing a foundation permit. That report typically runs a few hundred to a few thousand dollars and adds weeks of lead time. In Fremont’s hillside tracts or the higher parts of Hayward, that’s less common. A full bathroom remodel in Union City runs $9,000 to $28,000, and that range assumes the geotech step is handled correctly. We factor it in from day one. Call (877) 610-1318 for an exact quote on your address.
Every bathroom remodel we do carries our 90-Day Done Right Promise in writing. If something isn’t done right, one call brings Tom back to make it right. That’s not a marketing line; it’s on the contract. We also pull permits and get inspections signed on every eligible job, which means the work is checked by the city, not just by us.
