If you’re searching “bathroom remodeling near me” from a Union City address, you’re probably in one of two situations. Maybe you have a single full bathroom in one of the city’s original 1960s tract homes. No one has touched it since the builder finished the house. Or maybe you have a primary bathroom with a standard builder-grade tub and vanity. You want it to actually work for how your household uses it today.
Both situations are common in Union City. A large share of the housing stock here dates back to when Alvarado and Decoto were still separate towns. They merged to form Union City in 1959. Older single bathroom layouts are common in those homes. That’s a big reason “small bathroom remodel” comes up as often as full gut jobs. Union City homeowners call us for both.
Every project starts the same way regardless of size. First, we have a phone call to talk through scope and rough budget. Next comes a free design consultation at your home. We put together a written, itemized quote rather than a verbal ballpark.
Once you sign off, our team pulls the permit through the City of Union City Building Division on Alvarado-Niles Road. From there, we schedule inspections and manage the build with our own crew for most trades.
Union City sits close enough to the Bay that bathrooms run more humid than homes further inland. Because of that, we default to a full waterproofing membrane behind tile in wet areas. We also size exhaust fans to the room instead of installing whatever came with the house. That detail matters more here than it would in a drier East Bay suburb.
Pricing depends mostly on scope, not square footage alone. For a Union City hall or secondary bathroom, a finish-level refresh typically runs $15,000 to $30,000. That covers new tile, vanity, toilet, and fixtures. A full midrange remodel usually runs $35,000 to $70,000. That range covers projects that move fixtures or open up a small, boxed-in layout. A custom primary or spa-style bathroom can run $70,000 to $150,000 or more. That level typically includes a curbless shower and higher-end finishes.
Three things drive the biggest cost swings in Union City. The first is how much plumbing we need to relocate. The second is what we find once demo starts in an older house. The third is how much wet area waterproofing we need to redo instead of just patching.
A lot of our calls come from Union City, Fremont, and Hayward. Homeowners there often want compact bathrooms, sometimes as small as 5×8 feet, in older homes with smaller original layouts. For those projects, the work is less about adding square footage and more about reclaiming what’s already there. We swap in a corner shower instead of a tub and shower combo. We use a wall-mounted or slim-profile vanity. And we add recessed niches instead of surface-mounted shelving.
It’s a different discipline from a full remodel. It’s also where our small-format bathroom work across the East Bay tends to concentrate. See our broader East Bay bathroom remodeling coverage for how pricing compares in nearby Hayward and Fremont.
Sometimes a project touches the rest of the home too. That might mean new flooring that carries from the hallway into the bathroom, or a broader home remodeling scope. Either way, we handle it under the same permit and crew.
Our office is in Hayward, and we regularly work throughout Union City, including the Old Alvarado and Decoto areas. We also cover Fremont, Castro Valley, and the rest of Alameda County. If you don’t see your address here, ask us. We take on projects throughout the wider Bay Area as scheduling allows.
