AfterFast, Reliable Bathroom Remodeling Across Union City
A full bathroom remodel in Union City runs $9,000 to $28,000, and the wide spread comes down to one thing most homeowners don’t see coming: what’s behind the walls of a 1960s or 1970s tract home built on former bay marsh. We’ve worked enough of these houses to know the pattern. You open a wall to move a vanity and find undersized framing, corroded rough-in, or a rotted cripple wall that predates California’s modern seismic codes. That’s not a reason to panic. It’s a reason to hire a contractor who plans for it, writes it into the contract, and doesn’t hand you a surprise invoice at the end. Call (877) 610-1318 and we’ll walk the job with you before you spend a dime.
Why Barrett & Sons Construction Is Union City’s Preferred Bathroom Remodeling Company
You want a name on the truck, not a franchise with a call center. Tom Barrett started Barrett & Sons in 1998, and his sons run the crews. When you call, a live person answers. When something’s not right, Tom comes back, because he lives twenty minutes away and wants to know about it. That’s the whole deal, and it’s written into every contract as the 90-Day Done Right Promise.
Union City throws a curve at every contractor the first time they work here. The flatlands sit on former bay marsh and tidal fill, much of it inside CGS-designated liquefaction hazard zones. We know the city’s permit desk, we know when a soils report is coming, and we set expectations around that before the first wall is opened. No vague “we might need an engineer” talk. If the city is going to require a geotechnical report, we tell you that at the estimate and we write the allowance into the contract so it’s not a surprise waiting for a date.
Every scope change, every allowance, every price adjustment comes to you as a written change order before work happens. You approve it in writing or we don’t do it. We pull permits and get inspections signed on every eligible job, because the permit inspector works for you, not for me. And if you want to check us out before you sign anything, Tom publishes his name, his address, and his license number. Look it up.
Our Bathroom Remodeling Services in Union City
Full Bathroom Remodeling
A full gut remodel in Union City usually means taking a 5×8 or 5×10 bath in a post-1959 tract home down to the studs and rebuilding it. On these houses, that almost always reveals something. We open the wall, document what we find, and price the repair as a written change order before we touch it. You never get a surprise bill because we never work from surprise. The finished room gets new waterproofing, new fixtures, and a permit sign-off that says it was done right. We carry KraftMaid vanities and Cambria quartz, so the materials are brands you can look up, not mystery boxes off a van.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Union City runs $4,500 to $12,000, and on liquefaction-zone parcels the subfloor work is what separates a shower that lasts from one that cracks in a year. We rebuild shower pans with the existing foundation in mind, and when Union City’s building department requires a geotechnical soils report, we’ve already written that step into your contract. Frameless glass enclosures are a big part of what we install here, and the detail work matters: those delta winds off the bay drive moisture into exterior walls, so the waterproofing behind the tile has to be right the first time.
Tub-to-Shower Conversion
A tub-to-shower conversion in Union City typically costs $3,500 to $10,000. It’s the single most popular upgrade we do for homeowners in the Decoto and Alvarado districts, where the original tub has seen forty or fifty years of hard water and the owner wants a low-threshold entry. We handle the drain relocation, the new pan, the valve, and the waterproofing, and we pull the permit. If the city requires an inspection before we close the wall, we schedule it, and we don’t cover anything until the inspector signs off. That’s how it should work.
Vanities, Tile & Fixtures
Bathroom vanity installation in Union City runs $800 to $3,000 depending on whether it’s a simple swap or a custom built-in. The old vanities in these houses are usually original to the tract build, which means particleboard swollen from bay moisture and stopped-up shutoffs. We replace them with solid, name-brand cabinets and set the new plumbing right. Tile and fixture work follows the same rule as everything else we do: scope in writing, allowances in writing, and a fixed price you approve before the tile saw comes out.
Small Bathroom Remodels
Small bathroom remodels in Union City, the powder rooms and half baths, run $5,000 to $12,000. These are the ones where a homeowner thinks it’s a weekend project, then finds a split subfloor or a corroded drain fitting. We keep the scope tight and the paperwork tighter. You know exactly what’s included, exactly what isn’t, and exactly what a change costs before it’s approved.
Trusted Brands We Service in Union City
We install materials you can verify, not house-brand mystery products. In Union City bathrooms, you’ll see KraftMaid and Cambria on the vanity side, and we stock common repair parts locally so a mid-job parts need doesn’t stall the project. For exterior work that touches a bathroom addition or bump-out, we use premium hardscape products like Techo-Bloc and Quikrete where they’re the right call. The point isn’t the brand name on the box. It’s that you can look up what we’re installing and know it’s a real product with a real warranty, installed by a crew that carries the Barrett & Sons name and passes a background check before they ever walk through your door.
Common Bathroom Remodeling Problems We See in Union City Homes
- Bay moisture and rotted wall framing: Union City’s position at the southern end of San Francisco Bay means shallow groundwater and soil moisture that wicks into older studs and sill plates. Open a shower wall in a 1960s tract home and the bottom plate is often soft to the touch.
- Outdated wiring behind the walls: Homes built through the mid-1970s have wiring that predates modern bathroom code requirements. Once a wall is open, the city often requires an upgrade to a dedicated GFCI circuit, and that’s a code-triggered cost, not a contractor markup.
- Failed waterproofing and delta-wind damage: Strong bay winds drive rain into exterior walls, and if the original moisture barrier is shot, the tile is sitting on damaged substrate. Re-tiling over that without fixing the envelope just hides the problem for one more wet season.
- Cracked slabs on liquefaction-zone parcels: Homes near the old Alvarado salt pond margins sit in CGS-designated Seismic Hazard Zones. A bathroom subfloor that’s cracked or settling often points to a foundation issue that needs an engineer’s look before new tile goes down.
Pricing for Bathroom Remodeling in Union City, CA
Here’s what a bathroom remodel actually costs in Union City, based on the jobs we’ve priced in 94587. A full remodel runs $9,000 to $28,000. A small bath or powder room lands between $5,000 and $12,000. Walk-in shower installation starts around $4,500 and tops out near $12,000 when structural work is involved. Tub-to-shower conversions run $3,500 to $10,000, and a vanity alone is $800 to $3,000. The single biggest cost driver in Union City isn’t the tile or the fixtures. It’s what the city requires once walls are open: geotechnical reports, engineering review, and foundation upgrades on liquefaction-zone parcels. We write every one of these items into your contract as a named allowance with a dollar figure, so the final number comes from decisions you made, not surprises we handed you.

FAQs - Bathroom Remodeling in Union City
Generally no. A straight vanity replacement, where structural work is not being done and no walls or floors are opened beyond the footprint of the existing cabinet, typically does not require a geotechnical report. The trigger is structural: moving a drain, opening a wall to structural members, or altering the subfloor. Union City’s building department will tell you what’s required for your specific parcel, and we’ll find out before you commit, not after the wall is open. Call (877) 610-1318 and we’ll check it for you.
Because Union City’s flatlands sit on former bay marsh and tidal fill with shallow groundwater and CGS-designated liquefaction zones. When we move a drain or touch the subfloor, the city frequently requires a geotechnical soils report and engineered review, which adds 4 to 6 weeks and real dollars to the permit process. Fremont’s hillside tracts don’t carry that same requirement. It’s not a contractor markup. It’s the ground you’re building on, and we write it into the contract as a named allowance so you see it coming.
We document it, price it, and get your written approval before we touch it. Dry rot behind a shower wall in a Decoto tract home usually means the original waterproofing failed years ago and bay moisture has been working on the framing ever since. We cut out the damaged material, repair or sister the framing, and rebuild with proper waterproofing before tile goes back up. The permit inspector signs off before we close anything, and you see every dollar of that repair as a written change order, not a surprise on the final invoice.
Yes, on permitted jobs. When the scope includes plumbing, electrical, structural, or waterproofing work, Union City’s building department requires inspections at specific stages before walls are closed. That’s not an inconvenience, it’s the city making sure the work is safe. We schedule the inspections, meet the inspector on site, and get sign-off before we cover anything. The inspector works for you, not for me.
Expect water damage under the flooring and possibly compromised subfloor or framing. In a 1970s Union City tract home, a spongy floor near the tub usually means years of small leaks or condensation have softened the wood. What we find determines what happens next. If the subfloor is bad, we replace it. If the framing is damaged, we repair or sister it. And if your parcel is in a liquefaction zone and the city wants an engineer’s review before we proceed, we’ll handle that too, with every cost in writing before work continues. For an exact quote, call (877) 610-1318. Estimates are free.
