Fast, Reliable Bathroom Remodeling Across Half Moon Bay
A full bathroom remodel in Half Moon Bay typically runs between $9,000 and $28,000, with smaller refreshes starting around $5,000 and high-end coastal projects exceeding $30,000 when custom tile, frameless glass, and structural repairs enter the picture. We schedule free estimates across the 94019 zip code and the surrounding communities, and Tom Barrett’s crew has worked in enough fog-soaked bathrooms on the coastside to know what’s behind the walls before the first tile comes up. If you’re weighing a tub-to-shower conversion, a walk-in shower, or a full gut renovation, call (877) 610-1318 and we’ll walk the space with you and put numbers on paper.
Why Barrett & Sons Construction Is Half Moon Bay’s Preferred Bathroom Remodeling Company
Barrett & Sons Construction has been owner-operated since 1998, and the difference shows in how a job runs. Tom Barrett’s sons lead the crews, so the person who shakes your hand at the estimate is the same person who answers when you call about the nail punch list. Customers around Half Moon Bay appreciate that a live person answers the phone 24 hours a day, not a voicemail box, and that every price change arrives as a written change order before a single nail moves. The 90-Day Done Right Promise sits on every contract: if something isn’t right, one call brings us back.
What really builds trust on the coastside is local knowledge. Half Moon Bay’s marine layer keeps humidity high and salt in the air year-round, and we’ve opened enough walls in the older cottages off Kelly Avenue and the mid-century ranches along Highway 92 to know what that does to studs, subfloor, and plumbing. We scope for what we’ll actually find, not what a national outfit assumes from a cubicle in another state. Ask anyone on your street, or look up the license number yourself.
Our Bathroom Remodeling Services in Half Moon Bay
Full Bathroom Remodeling
A full remodel in Half Moon Bay means we take the room to the studs and rebuild it right: new waterproofing, new valve plumbing, new ventilation, new fixtures, new finishes. Homes near Miramar and Princeton-by-the-Sea often need sill plate and subfloor remediation once we open things up, because decades of fog drip and salt air have worked their way into the framing. We write that into the scope up front, not as a surprise change order later. Read more about our Bathroom Remodeling process if you’re in the early research phase.

Walk-In Showers & Shower Remodeling
Walk-in shower installation in Half Moon Bay runs $4,500 to $12,000 depending on tile choices, glass enclosure style, and whether we’re correcting a rusted drain assembly or a compromised shower pan. We use Schluter waterproofing systems and Grohe fixtures on many of these jobs, materials you can look up and verify. Curbless entries are common requests from older homeowners who want to age in place, and we handle the slope, drainage, and waterproofing details that make a curbless shower actually work in a fog-humid climate.

Tub-to-Shower Conversion
A tub-to-shower conversion in Half Moon Bay typically lands between $3,500 and $10,000, and it’s one of the most practical upgrades for the smaller bathroom footprints you find in older coastside homes. We remove the tub, reframe the opening if needed, install a properly sloped shower base, and finish with tile or a solid-surface surround. The permit inspector works for you, not for me, which is why we pull permits and get the plumbing and waterproofing signed off before tile goes down.

Vanities, Tile & Fixtures
Vanity installation runs $800 to $3,000 in Half Moon Bay, and tile work gets priced by the square foot once we measure the actual surfaces. We install real, nameable materials, including Sterling fixtures and Schluter waterproofing, never mystery brands off a van. Whether you want a floating double vanity with stone top or a simple single-bowl refresh, the allowance sheet shows exactly what you’re paying for before we order anything. An allowance that isn’t on paper is a surprise waiting for a date.

Trusted Brands We Service in Half Moon Bay
We carry and install premium brands you can look up, including Schluter waterproofing, Grohe fixtures, and Sterling products, and we coordinate materials delivery to Half Moon Bay jobsites so you’re not waiting on a truck from out of the area. When a valve body or a tile trim piece shows up wrong, we handle the return and reorder without making you play project manager. Coastal humidity demands better materials, and better materials demand a contractor who knows how to install them correctly the first time.
Common Bathroom Remodeling Problems We See in Half Moon Bay Homes
- Rusted metal fasteners and hardware. The persistent marine layer means exposed screws, brackets, and trim nails corrode fast. We spec stainless or hot-dipped fasteners on every moisture-facing connection, because the standard zinc stuff fails early here.
- Rot in sill plates and subfloor. Older wood-framed homes in the Old Town core and along the highway corridors have absorbed decades of fog drip. Once we open a floor or a lower wall, we routinely find rot that needs replacement before any finish work begins.
- Undersized ventilation. A bathroom fan that can’t move enough moist air in a climate this humid will turn a fresh remodel into a mold problem within a couple of years. We upgrade CFM ratings and duct runs as standard on coastside jobs.
- Coastal Commission surprises. Even an interior remodel in Half Moon Bay can trip a Coastal Development Permit review if it alters square footage or touches a nonconforming structure. We parse the exempt categories before we scope, so the job doesn’t freeze mid-construction.

FAQs - Bathroom Remodeling in Half Moon Bay
A full bathroom remodel in Half Moon Bay runs $9,000 to $28,000, and a small bathroom remodel runs $5,000 to $12,000. The coastal conditions push material specs and sometimes force remediation work once walls are open, so we price those realities up front rather than surprising you later. Call (877) 610-1318 for an exact quote, and the estimate is free.
Yes, on every eligible job, including Coastal Development Permits when the scope requires them. Virtually all of Half Moon Bay’s developed area falls within the California Coastal Commission’s coastal zone, and even some interior remodels can trigger coastal review if they alter exterior square footage or touch a nonconforming structure. The permit inspector works for you, not for me, which is why we’d rather have the paperwork right from day one.
Only if the scope changes, and only in writing. Every price change is a written change order issued before work proceeds. What we find when we open a wall, whether it’s rot in a sill plate or a rusted drain assembly, is the most common reason scope grows, and we document it with photos and a written number before we touch it. No surprise invoices at the end.
Most full bathroom remodels in Half Moon Bay take three to six weeks from first tear-out to final inspection, depending on tile footage, glass lead time, and whether coastal permitting adds a review clock before physical work starts. Tub-to-shower conversions and shower replacements are usually faster, often two to three weeks. We’ll give you a written schedule with the estimate, and we keep it updated if materials or inspections shift.
Yes, every completed job is backed by the written 90-Day Done Right Promise. If it’s not done right, Tom comes back and makes it right, one call. All we ask is that you tell us about the issue during that window so we can fix it while the crew is still close by.
If you’re ready to talk bathroom remodeling in Half Moon Bay, call (877) 610-1318 for a free estimate. Worth remembering: we also offer free second opinions on any written estimate, no trip charge inside San Mateo County, and a permanent 10% discount for seniors and veterans.
