AfterFast, Reliable Bathroom Remodeling Across Hillsborough
Bathroom remodeling in Hillsborough typically runs $9,000 to $28,000 for a full renovation, with smaller refreshes and walk-in shower conversions starting around $5,000 and $4,500 respectively. The number that matters on your project is shaped by something most nearby contractors don’t plan for: the Town of Hillsborough’s Architectural Review Board, which sits on top of the standard building permit and often requires architect-stamped plans before a single wall moves. That review layer adds weeks and real cost, which is why this is not a job for a crew that spends most of its time in flat, commercially zoned towns like Burlingame. We’re Barrett & Sons Construction, we’ve worked through the 94010 ARB process on estate bathrooms across town, and we’d rather tell you what it actually takes than hand you a fantasy quote. If you’d like a straight number, call (877) 610-1318.
Why Barrett & Sons Construction Is Hillsborough’s Preferred Bathroom Remodeling Company
The homes in Hillsborough aren’t like anywhere else on the Peninsula. Most were built between the 1910s and 1960s, which means a bathroom remodel here almost always uncovers something behind the walls: original galvanized supply lines, cloth-wrapped wiring, or plaster thick enough to make even a simple plumbing relocation a structural conversation. We prepare for that. We’ve remodeled bathrooms in Spanish Colonial Revival estates on the lower slopes and mid-century homes up near the private roads, and we know what the ARB will flag before you spend a nickel on plans denied at the next hearing.
Tom Barrett puts his name, his address, and his license number on every contract. If something’s not right, he lives close enough to drive over and see it himself. Our crews are Tom’s sons and their teams, not dispatched labor from an out-of-state call center. A live person answers the phone 24/7, and every price change arrives as a written change order before work proceeds. For Hillsborough homeowners who’ve been burned by a big operation, that’s the difference between a surprise and a signed piece of paper.
Ask anyone on your street, or look up the license number yourself. We’re the company that pulls permits and gets inspections signed on every eligible job, because the last contractor most people used told them permits were optional. We also back every finished project with the written 90-Day Done Right Promise: if it’s not right, one call brings Tom back. That’s in the contract, not the fine print, and it matters on a $25,000 bathroom where the shower pan is the last thing you want failing a month after final payment.
Our Bathroom Remodeling Services in Hillsborough
Full Bathroom Remodeling
A full bathroom remodel in a 1930s Hillsborough estate usually means gutting to the studs, replacing plumbing and electrical, and rebuilding to current code before the finishes even start. We handle that entire sequence, including foundation access under post-and-pier floors and seismic strapping in high-hazard zones near the San Andreas ridgeline. Full bathroom projects here run $9,000 to $28,000 depending on size, fixture grade, and what the walls reveal once they’re opened.
Walk-In Showers & Shower Remodeling
Walk-in showers are the single most requested upgrade in Hillsborough’s older homes, where original tubs crowd bathrooms that were designed before anyone imagined a curbless entry. We routinely convert 1940s tub alcoves into walk-in showers with frameless glass enclosures, and we plan for the thick plaster walls that make waterproofing and valve placement more involved than in a newer house. Walk-in shower installation in Hillsborough typically runs $4,500 to $12,000.
Tub-to-Shower Conversion
For homeowners staying in the house long-term, tub-to-shower conversion is the practical move. We remove the old cast iron tub, address any subfloor rot common in homes with hillside drainage against the foundation, and install a code-compliant walk-in shower with proper slope and a curb height that works for aging knees. Tub-to-shower conversion here ranges from $3,500 to $10,000, with final price tied to whether we’re moving the drain line or reusing the existing rough-in.
Vanities, Tile & Fixtures
When the full remodel can wait but the vanity has to go, we do smaller scope work with the same paperwork discipline: vanities, tile, and fixture swaps arrive priced line by line, with allowances in writing. Hillsborough’s ARB cares about exterior massing, but inside, the material choices are yours. We install named brands you can look up, not mystery fixtures off a van. Vanity installation runs $800 to $3,000, and a focused tile and fixture refresh usually lands on the low end of a small bathroom remodel at $5,000 to $12,000.

Trusted Brands We Service in Hillsborough
We carry and install brands whose names mean something on an estate property, including Simonton and Ply Gem for windows and glass enclosures that a bathroom remodel sometimes tags onto. When a Hillsborough job needs replacement glass block or a new vinyl window in a bathroom that’s being opened up, we can source local parts faster than a national outfit ordering from a regional hub. If your remodel expands and you’re suddenly talking about full window replacement, we also handle Windows & Doors in Hillsborough with the same written change order discipline. And if you discover roof flashing trouble above that upper-floor bathroom, our Roofing in Hillsborough crew works the same way: permits pulled, prices in writing, one call to fix it if it’s not done right.
Common Bathroom Remodeling Problems We See in Hillsborough Homes
- Drain line runs from original clay or cast iron that’s failing. Homes on steep hillside lots put long drain runs under slabs and through foundation walls. When original cast iron fails, the bathroom remodel stops until the drain gets sleeved or replaced, and we do that before tile goes up so you’re not cutting into a finished floor.
- Post-and-pier foundations moving under expansive clay. Much of Hillsborough sits on Bay Area clay that swells with winter rain and shrinks in summer. That movement cracks tile, separates tub flanges, and causes shower pans to fail. We check the subfloor and floor joists as part of every bathroom estimate.
- ARB design review adding lead time to even interior remodels. This is the one that surprises every homeowner the first time. Substantial remodels in Hillsborough need architect-stamped plans and ARB sign-off, which means your bathroom timeline includes a review cycle you can’t skip and can’t rush. We schedule for it from day one.
- Valve and supply line access blocked by 3-inch plaster walls. On estate homes, moving a shower valve often means cutting through plaster and lath thick enough to hide original wiring. We plan the access path before we quote, so the price includes the opening work and the repair, not just the part you asked about.

FAQs - Bathroom Remodeling in Hillsborough
We can typically get an estimate to you within a week and start work within a few weeks once the scope is signed, but Hillsborough ARB review often adds its own schedule on substantial remodels. The review cycle runs on the town’s calendar, not ours, and that’s true for every contractor in 94010. Call (877) 610-1318 and we’ll tell you what your project’s timeline actually looks like based on the scope and current ARB load.
Yes, we work across all of Hillsborough, including the narrow private roads on the upper hillside where crane staging and material delivery get genuinely difficult. We plan materials handling for the terrain before we quote, so you’re not surprised by an access fee after the job starts. If you’re on a small private lane off of Ralston Avenue or near the Burlingame border, we’ll have already driven it.
Generally yes, because the Town of Hillsborough’s ARB design review and architect-stamp requirements add plan costs and time that neighboring cities don’t impose on interior remodels. A full bathroom that runs $9,000 to $28,000 here might cost less for the same fixture package in Burlingame, but the Hillsborough permit path is part of what you’re paying for. We’ll show you that line on the estimate, not bury it in the total.
Every completed project is backed by our 90-Day Done Right Promise, written on the contract. If tile cracks, a valve leaks, or a shower pan fails within that window, one call brings Tom back to make it right. That’s the same guarantee whether the job is a $3,000 shower replacement or a $28,000 full estate bathroom.
Yes. Every crew member on a Hillsborough job site is background-checked, uniformed, and works under the Barrett & Sons name. They’re Tom’s sons and their teams, not strangers dispatched by a call center. For homeowners who value knowing who’s in the house, that matters as much as the tile pattern. Call (877) 610-1318 to set up a free estimate.
