Fast, Reliable Bathroom Remodeling Across Union City
A full bathroom remodel in Union City typically runs $9,000 – $28,000, with small bathroom remodels landing between $5,000 and $12,000. The number moves based on what we find when the old tile comes up, especially in the ranch homes east of Mission Boulevard where original subfloors have been soaking up bay air humidity for sixty years. Call (669) 274-2362 and we’ll give you a written number before any work starts, not a verbal ballpark that changes at the door.

We work on tight Union City lots every week. That means we know how to stage a trailer in a driveway without blocking the sidewalk, how to carry a Kohler tub through a side gate without scratching the stucco, and how to keep demo noise inside the hours Union City code enforcement actually allows. The Bathroom Remodeling team at Penhallow puts the full price, the arrival window, and the 365-day guarantee in writing before demo day.
Why Penhallow Remodeling San Jose Is Union City’s Preferred Bathroom Remodeling Company

Union City homeowners have told us the same story more times than we can count: a contractor quoted one number over the phone, tore out the shower, found a problem, and the final invoice looked nothing like the first estimate. That’s exactly what the Kingswell standard exists to prevent. Since 2004, every Penhallow project has run on a written price, a defined arrival window, a clean job site, and a written guarantee. Say the price before the work. Show up in the window we gave. Leave the place cleaner than we found it. That’s The Kingswell Way, and it’s the same on a $5,000 tub-to-shower conversion in Union City as it is on a $28,000 primary bath gut.
Trevor Nash runs the Union City work the same way he runs every job: the number on day one is the number on the invoice. If something fails inside the guarantee period, we come back and fix it at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every project.
You’ll also get a live person when you call (669) 274-2362, at any hour. Not an answering service, not a voicemail prompt. A real person who can schedule your estimate and answer a question about your project. The technicians who arrive are background-checked and in uniform, so you know who’s walking through your door.
Styles & brands we work with







Small Bathroom Remodel in Union City
A Small Bathroom Remodel in Union City typically runs $5,000 – $12,000, and it’s the most common project we take on in the flatlands tracts where ranch-style homes pack a 5-by-8 bath into a floor plan built before anyone imagined a double vanity. The job usually means keeping the existing footprint, replacing the tub or shower, swapping the vanity, setting new tile, and updating fixtures. What drives the price up is what’s underneath: homes near the Hayward Fault often have settled slabs and original cast-iron drains that need more work than the homeowner expected.
Tight-Lot Staging and Access Planning
On a narrow Whipple Road lot, there’s no room for a dumpster in the street without a permit, and no side yard wide enough for a Bobcat. We plan the entire material flow before demo starts: trailer in the driveway, tile and cement board staged in the garage, old debris carried out the same path the new materials come in. Access planning is part of the written quote, so you’re not surprised by a staging fee halfway through.
Foundry-Dated Plumbing and Subfloor Reality
Many Union City ranch homes still have the original cast-iron waste lines and a subfloor that’s absorbed decades of moisture from the marine layer. A Small Bathroom Remodel in one of these houses often means replacing the drain flange, sistering a joist or two, and laying new cement board substrate (the moisture-resistant layer behind your tile) before the first tile goes down. We write that into the quote when we see it, not after the demo.
Shower Remodel in Union City
A Shower Remodel in Union City runs $3,000 – $12,000 depending on whether you’re replacing a shower pan and valve or converting a tub to a walk-in shower with frameless glass. In the 1950s and 60s ranch homes that dominate the neighborhoods east of Mission Boulevard, the original shower pans are often lead or hot-mopped and well past their useful life. When the tile comes off and the pan is cracked, that’s the moment the real scope declares itself.
Walk-In Showers and Curbless Conversions
Walk-in shower installation in Union City runs $4,500 – $12,000. Curbless designs are popular with homeowners planning to age in place, but they require dropping the shower floor into the framing or raising the rest of the bathroom floor. On an unretrofitted 1960s foundation, that can trigger a plan-check requirement for strapping or a shear wall upgrade near the load-bearing wall. We flag that before you commit, not after the framing is open.

Valve and Fixture Selection With the Bay in Mind
The same persistent fog that keeps Union City mornings cool also corrodes cheap metal fittings faster than you’d expect. We install Moen and Kohler valves because they hold up in humid, salt-tinged air, and because both manufacturers stand behind their finish warranties. We stock common valve bodies and cartridge kits locally, which means less waiting when a shower remodel uncovers a failed pressure-balancing valve behind the old tile.
Trusted Brands We Service in Union City
When we install a Cambria quartz vanity top or a Silestone shower surround in Union City, you’re getting two layers of protection: our 365-Day Done Right Promise and the manufacturer’s own warranty on the product. We work with Wellborn cabinetry, Kohler and Moen fixtures, and Cambria, Silestone, and Caesarstone countertops. Because we stock common replacement parts locally, a cracked cartridge or a failed mixing valve doesn’t leave you waiting a week. The products behind the guarantee are as solid as the promise itself.

AfterCommon Bathroom Remodeling Problems We See in Union City Homes
- Corroded cast-iron drain flanges from bay air humidity. The original 1950s flanges under many Union City showers are rusted thin from decades of moist marine air, and they usually crumble when we pull the old shower pan. Replacing one is a few hundred dollars, but missing it means a slow leak inside your wall cavity.
- Dry-rotted subfloors under original tile. Union City’s fog keeps humidity high, and old tile beds trapped that moisture against unventilated wood for sixty years. Tile that cracks within a year of a new install is almost always a subfloor problem we didn’t catch, or one we told you about and you hoped would hold.
- Unpermitted work from a previous owner. We regularly find tub-to-shower conversions and added bathrooms that never pulled a permit. When we open the wall and find plumbing that was never inspected, the plan checker will want it brought up to current code before we can close up.
- Stop-work orders from noise complaints on tight lots. On a dense Union City cul-de-sac, starting demo before 8 a.m. or skipping the party-wall notice for a shared wall is a fast way to get code enforcement on site. We schedule noisy work inside allowed hours and talk to neighbors before demo day.

What moves the number up in Union City specifically: foundation work on east-side ranch homes, replacing corroded cast-iron drains, upgrading unpermitted plumbing from a previous owner, and the extra staging labor on tight flatlands lots. A walk-in shower with frameless glass and a Cambria top will land higher in the range than a standard tub-to-shower swap with a prefabricated pan. Call (669) 274-2362 and we’ll give you a written number for your exact project after looking at the space, not before we’ve seen the subfloor.

FAQs About Bathroom Remodeling in Union City
Yes. A tub-to-shower conversion changes the fixture and usually moves or replaces the drain, which requires a plumbing permit in Union City. In a 1950s ranch east of Mission Boulevard, the plan checker will often require a shear wall or strapping upgrade if the bathroom is near a load-bearing wall on unreinforced perimeter footings. We pull the permits, schedule the inspections, and the permit line is in your written quote. Call (669) 274-2362 and ask us to walk through what your specific house will need.
Sometimes, but we tell you before you sign, not after. On a tight flatlands lot off Whipple Road, staging might mean a trailer in the driveway, materials in the garage, and a dumpster scheduled for a short window instead of parking one on the street for two weeks. That labor is a line item in the quote, not a surprise change order. If your lot has no driveway access for a trailer, we adjust the schedule and price accordingly before demo starts.
Not for a straightforward retile, and not automatically. If the slab has settled and the tile is cracking along stress lines, we’ll want a structural look before we put new tile over a moving surface. Many homes east of Mission Boulevard sit on expansive clay or engineered fill, and a bathroom that shows diagonal cracks across the slab may need more than a new tile bed. We’ll tell you if we think an engineer needs to sign off, and that conversation happens before we set tile. Call (669) 274-2362 for a straight answer on your floor.
We schedule noisy work inside Union City’s allowed construction hours, which typically means no demo before 8 a.m. on weekdays. For a shared wall or a party-wall situation on a dense cul-de-sac, we notify the adjacent homeowner before we start, so the first hammer swing isn’t a surprise. We also keep the work area clean at the end of every day. A clean job site is part of The Kingswell Way, and it goes a long way toward keeping the street calm.
You get a documented change order before any additional work happens. In a Union City ranch with unretrofitted perimeter footings, opening a bathroom wall sometimes reveals settled framing or an unbolted mudsill that the plan checker will not let us close over. At that point, we stop, show you what we found, give you a written price for the additional scope, and you decide. The draw schedule adjusts to the new written number. You’re never on the hook for work you didn’t approve in writing.
