AfterFast, Reliable Bathroom Remodeling Across Gilroy
Bathroom remodeling in Gilroy typically runs $9,000 to $28,000 for a full gut-and-rebuild, with smaller jobs like a tub-to-shower conversion landing between $3,500 and $10,000. Most projects take two to four weeks once materials arrive, and we give you the written price before any work starts. If you’re dealing with a shower that leaks, a tub you can’t safely step into, or a bathroom that’s simply done being 1998, call (936) 259-2607 for a free estimate. We serve Gilroy neighborhoods from Eagle Ridge to the downtown historic district, and we know what these houses need because we work inside them every week.
Why Penhallow Remodeling Is Gilroy’s Preferred Bathroom Remodeling Company
Gilroy homeowners call us after they’ve been burned, usually by a contractor who gave a verbal ballpark and then changed the number after demo day. That doesn’t happen with Penhallow. Trevor Nash built this company on one rule: say the price before the work, show up in the window we gave, and stand behind what we install. The 365-Day Done Right Promise is written into every contract. If something fails inside that year, we come back and fix it at no charge, and if it fails again, the second return visit is still free. That’s the Kingswell standard, and it’s been operating since 2004.
We’re part of the Kingswell family of companies, and Bathroom Remodeling is a core trade, not a side gig. Every technician who walks into your Gilroy home is background-checked and uniformed. A live person answers the phone 24/7, so when you call about a leak behind the vanity at 9 p.m., you get a real human, not a voicemail. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, and our crews serve Gilroy locally.
Shower Remodel in Gilroy
A Shower Remodel in Gilroy means more than swapping tile; it’s about fixing the moisture and ventilation problems that Gilroy’s heat makes worse before they rot your subfloor. We rebuild the shower pan, redo the tile and grout, replace the valve and trim, and install a proper exhaust path to the roof. A full shower remodel in Gilroy runs $4,500 to $12,000 for a walk-in installation, and $3,000 to $8,500 for a shower replacement, depending on size, glass, and whether we’re correcting framing damage underneath.
Waterproofing Done the Right Way
We set tile over cement board with a waterproofing membrane, never greenboard. Greenboard was standard twenty years ago and it’s one reason Gilroy tract homes from the 1990s are now showing hidden rot. The membrane is the layer that keeps water from ever reaching the framing.
Frameless Glass and Finish Choices
Most Gilroy homeowners want a frameless glass enclosure, and we spec glass that’s tempered and coated to resist hard-water spotting. We install Moen and Kohler valves and Delta trim, and we avoid builder-grade chrome that pits within a few summers in the valley heat.
Tub to Shower Conversion in Gilroy
A Tub to Shower Conversion in Gilroy replaces a step-over tub with a curbless or low-curb shower, which is a practical upgrade for homeowners who plan to age in place. The job involves removing the tub, reworking the drain line, rebuilding the wet wall, and installing tile, glass, and a new valve. In Gilroy this typically costs $3,500 to $10,000, with the final price driven by tile selection, glass configuration, and whether the existing floor structure needs reinforcement.
Why Gilroy Homeowners Choose a Walk-In Shower
The homes we work on in Eagle Ridge and along Mantelli Drive were built in a boom era when a tub in every bathroom was the default. Three decades later, those tubs are rarely used and the step-over is a risk for anyone with knee or hip issues. Converting to a low-curb shower makes the bathroom safer and adds usable floor space.
Drain and Vent Work During Conversion
Because a tub drain is 1.5 inches and a shower needs 2 inches, we rework the drain line, not just the visible tile. This is where unpermitted or fly-by-night work fails: a tub-to-shower conversion that keeps the old drain is a slow clog waiting to happen. We pull permits and pass inspection before the walls close.
Trusted Brands We Service in Gilroy
We install products from manufacturers that carry their own warranties alongside our 365-Day Done Right Promise. That means Kohler and Moen fixtures, Cambria and Silestone countertops, and KraftMaid cabinetry on vanities. We source materials to spec for Gilroy’s heat, which means no chrome that pits, no caulk that cracks in the first summer, and no exhaust fans rated below the square footage of your bathroom. Because we order from these trade suppliers regularly, parts for Gilroy jobs arrive faster than a homeowner ordering direct, and we handle any warranty claim for you.
Common Bathroom Remodeling Problems We See in Gilroy Homes
- Attic-ducted exhaust fans. Gilroy’s valley-gap position blocks the marine layer, so summer attic temperatures far exceed what coastal South Bay cities experience. When a bathroom exhaust fan terminates in the attic instead of the roof, that hot attic bakes the moist air right back onto your ceiling drywall. We see mold staining above showers in Gilroy tract homes that would never appear in Morgan Hill or Hollister.
- Builder-grade zinc and chrome hardware. Most Gilroy homes from the 1990s and 2000s shipped with cheap shower valve trim and fasteners. A decade of 100°F-plus summer swings inside the wall cavity causes pitting and seized valves. When we open these walls, the handle sometimes snaps off before the trim plate does.
- Greenboard behind tile with no membrane. Greenboard was code compliant in many 1990s builds, but it has no waterproofing value. A failed tub pan or valve leak soaks the greenboard, rots the subfloor around the floor flange, and you don’t know it until the toilet starts rocking.
- Slab movement from expansive adobe clay. Gilroy’s valley floor is adobe clay that shrinks and swells with the wet-dry seasonal cycle. That movement translates through slab-on-grade foundations as hairline cracks in tile and grout, especially in bathrooms adjacent to exterior walls on the sunny side of the house.

The biggest cost drivers in Gilroy are waterproofing compliance, tile and glass selection, and whether we find hidden framing or subfloor damage once the walls open. Homes in the hillside subdivisions east of US-101 toward the Diablo foothills fall under Chapter 7A wildland-urban interface rules, and if your bathroom is part of a larger addition in those areas, we spec ignition-resistant wall assemblies alongside the waterproofing. Estimates are free, and the number we hand you is the number on the invoice.

FAQs About Bathroom Remodeling in Gilroy
Yes, any remodel that alters plumbing, electrical, or structural framing in Gilroy requires a building permit from the City of Gilroy, and Santa Clara County inspectors enforce this closely. We pull all permits ourselves and sit with the inspector during walkthroughs. Unpermitted bathroom work will come up at resale inspection, and fixing it then costs more than doing it right now. Call (936) 259-2607 to confirm what your specific project requires.
Because Gilroy sits directly adjacent to the active Calaveras Fault, and local enforcement requires seismic-conscious structural details and Chapter 7A fire-resistant standards that a San Jose crew might not spec. A contractor who misses those requirements gets stopped at framing inspection, and the honest price to redo the work appears on the change order. Our Gilroy quotes include the compliance work up front. Call (936) 259-2607 for a written number that reflects the actual code burden here.
Gilroy’s valley-gap position blocks the marine layer, so summer wall and attic temperatures run far hotter than coastal South Bay cities. That means vinyl baseboards can warp, builder-grade chrome pits and seizes, and caulk lines crack early. We spec materials rated for high-temperature exposure, and we never vent exhaust fans into a Gilroy attic; the duct goes through the roof. We see mold staining on ceilings above showers in Gilroy tract homes that would never show that pattern in Morgan Hill, and it’s almost always an attic-ducted fan. If your ceiling shows water staining even without a roof leak, call us and ask about it.
A written price, a written arrival window, the full scope including waterproofing membrane and subfloor repair allowances, the permit and inspection schedule, and a guarantee that covers workmanship for a full year. Every Penhallow Remodeling contract includes all of that, plus the 365-Day Done Right Promise in writing. If something fails inside that year, we return and fix it at no charge, and a second visit for the same repair failure is free as well. Trevor Nash would rather fix a caulk line than argue about one.
A tub-to-shower conversion in Gilroy typically takes 5 to 8 working days once we start, depending on whether we find hidden subfloor damage or need to rework the drain and vent lines. Permitting can add a week or two on the front end, which we handle for you. If we open the wall and find greenboard rot from an old valve leak, we might add a day for subfloor sistering. We give you an honest time window up front and hold to it. Call (936) 259-2607 to get a start-date estimate for your project.
On a 1998 stucco tract home off Mesa Road in the Eagle Ridge area, our crew opened a hall bath and found the exhaust fan ducted straight into the attic, the subfloor around the toilet flange soft from a slow wax-ring leak, and 25-year-old greenboard behind the tub surround. We re-ran the exhaust to a roof cap, sistered the damaged subfloor, and rebuilt the wet wall with cement board and a Kohler tub-to-shower conversion. It passed inspection sign-off on the first rough-in walk. That’s the kind of work we do in Gilroy: we don’t cover problems up. We open the wall, show you what’s there, and fix it according to the code this city actually enforces.
If you’re ready for a bathroom that doesn’t stain the ceiling every August, call (936) 259-2607. We’ll schedule a free estimate, hand you a written price, and put the guarantee in writing before a single tile is set.
