Fast, Reliable Bathroom Remodeling Across Los Altos
A full bathroom remodel in Los Altos typically runs $9,000 to $28,000, with smaller projects like tub-to-shower conversions landing between $3,500 and $10,000. The wide range comes down to what’s hiding behind those 1950s and 1960s walls: outdated wiring, settled floors, and waterproofing that gave up years ago. We’re Barrett & Sons Construction, and we’ve spent nearly three decades opening up Los Altos bathrooms and handling what’s actually back there. Call (877) 610-1318 for a free estimate, and we’ll walk the job with you before any numbers get written down. Tom Barrett’s name, his address, and his license number are all published and verifiable. Look us up before you sign anything.
Why Barrett & Sons Construction Is Los Altos’s Preferred Bathroom Remodeling Company
We’re the owner-operated crew that answers its own phone. Tom Barrett founded this company in 1998, and his sons run the crews that show up in Los Altos. That means the person quoting your job is the same person accountable for it. No franchise dispatcher. No out-of-state call center. When you call (877) 610-1318, a live person picks up, day or night.
Los Altos homeowners tell us the same story over and over: a previous contractor quoted one number on the phone, then handed them a different bill at the door. So we do things differently. Every scope change arrives as a written change order before a single nail moves. Every allowance is written into the contract. If it’s not on paper, it’s a surprise waiting for a date, and we don’t do surprises.
We also know Los Altos’s permitting process the way only a local crew can. The city’s building department has its own design-review requirements, and the tree-preservation ordinance here is stricter than almost anywhere else in the Bay Area. That local knowledge keeps your remodel moving instead of stalling at the counter. Our Bathroom Remodeling work comes with permits pulled and inspections signed on every eligible job, and we back everything with the 90-Day Done Right Promise: if it’s not done right, Tom comes back and makes it right, one call.
Our Bathroom Remodeling Services in Los Altos
Full Bathroom Remodeling
A full bathroom remodel in Los Altos means gutting the room to the studs, correcting whatever’s back there, and rebuilding it right. For a 1960s ranch in the 94022 or 94024 zip codes, that almost always includes replacing cast-iron drain lines, adding GFCI protection, and re-waterproofing the shower pan before any tile goes up. We figure the unexpected into the contract as written allowances, so when the wall opens and something’s wrong, you’re not staring at a surprise invoice.

Walk-In Showers & Shower Remodeling
Walk-in showers make sense for Los Altos homeowners planning to stay in their homes. A curbless entry, a frameless glass enclosure, and a Schluter waterproofing system underneath the tile. If your shower sits against an exterior wall and we need to add a window for light, that triggers Los Altos’s design-review process and possibly a tree-canopy report. We handle that paperwork before it handles you. Grohe fixtures and Sterling bases are brands we install regularly, and we stand behind them.

Tub-to-Shower Conversion
Converting a tub to a walk-in shower is the most common bathroom project we’re asked about in Los Altos, and it runs $3,500 to $10,000. The real cost driver isn’t the demo or the tile, it’s what’s under the tub. Original post-and-pier foundations on Adobe clay mean the subfloor may have settled over sixty years. We check pier condition before we set a single shower base, because tile cracks within a year if the floor beneath it moves. We write that inspection into the contract, not as an afterthought.

Vanities, Tile & Fixtures
Replacing a vanity or re-tiling a bathroom floor sounds simple. In Los Altos, it’s often the project that uncovers ungrounded cloth wiring or a rotted bottom plate from a shower pan that leaked for a decade. We quote these jobs with a written contingency allowance tied to those specific conditions. If the vanity swap reveals a 60-amp panel that won’t pass inspection, you’ll see the change order in writing before we order the new subpanel.

Trusted Brands We Service in Los Altos
We install brands you can look up: Schluter waterproofing systems under every tiled shower, Sterling shower bases and tubs, and Grohe valves and fixtures. These aren’t mystery brands off the back of a van. We keep common Los Altos repair parts on hand for these lines, which means fewer dead days waiting on a distributor when a valve cartridge fails mid-remodel or a shower drain needs matching trim. If you’re getting a second opinion on a written estimate from another company, we’ll review it free, line by line.
Common Bathroom Remodeling Problems We See in Los Altos Homes
Los Altos’s housing stock is mostly single-story ranch and split-level homes built between 1950 and 1975. That means every remodel starts with the same question: what’s behind this wall? Here’s what we routinely find.
- Ungrounded cloth wiring and 60-100 amp panels. Open a bathroom wall in a 1962 Los Altos ranch and you’ll often find two-wire cloth cable that won’t pass a building inspection. Add a GFCI outlet or a heated floor, and the inspector will require the panel upgrade before sign-off. We write that contingency into the contract from day one.
- Rotted bottom plates from failed shower pans. A 1960s shower pan had a lifespan of about thirty years. Most are well past it. By the time you see cracked grout or a soft floor, the bottom plate underneath is often rotted through. We reframe before we tile, and the permit inspection covers the repair.
- Settled post-and-pier foundations on Adobe clay. Los Altos sits on expansive clay that swells in winter and shrinks in summer. Shallow perimeter and post-and-pier foundations move with it. A slab bathroom floor with a recurring crack line is usually a foundation issue, not a tile issue. We check before we set tile.
- Design-review and tree-canopy stops. Moving a drain line or adding an exterior wall window can trigger Los Altos’s design-review process. If a heritage oak sits within the root zone, you’ll need an arborist report and canopy-protection fencing before rough-in begins. We file that paperwork early. Many out-of-area contractors don’t find out until the job is already stopped.
Pricing for Bathroom Remodeling in Los Altos, CA
Los Altos bathroom remodels cost more than comparable work in Mountain View or Sunnyvale, and the reason is structural. The older ranch housing stock, the strict permitting and tree ordinances, and the foundation conditions all add steps that a contractor in a newer tract-home city never faces. Here are the ranges we quote in Los Altos:
| Project | Los Altos Price Range |
|---|---|
| Bathroom Remodel | $9,000 - $28,000 |
| Small Bathroom Remodel | $5,000 - $12,000 |
| Walk-In Shower Installation | $4,500 - $12,000 |
| Tub-to-Shower Conversion | $3,500 - $10,000 |
| Shower Replacement | $3,000 - $8,500 |

FAQs - Bathroom Remodeling in Los Altos
Probably not a whole-house rewire, but any new outlet or lighting added to that bathroom circuit will trigger a Los Altos inspector’s requirement for a modern grounded branch circuit and, if the panel is maxed out, a subpanel or panel upgrade. We handle this by writing an electrical contingency allowance into the contract before we open the wall. If the vanity swap stays with the existing wiring and no new circuits are added, the job can usually proceed as quoted. Call (877) 610-1318 and we’ll tell you what’s likely in your specific bathroom, based on the home’s age and what we’ve seen on your street.
Yes, you can. A tub-to-shower conversion works in a single-bath ranch, and for many Los Altos homeowners it’s the better choice because a curbless walk-in shower is safer and more usable as you age in place. The one thing to confirm before you start is resale. In Los Altos, where land value exceeds structure value on most lots, a single-bath home without a tub can affect some buyers. That’s your decision to make. We’ll convert the tub, check the subfloor and piers, and pull the permit. Call (877) 610-1318 for a free estimate on the conversion.
For most interior-only remodels, it doesn’t. The tree-preservation ordinance applies when work disturbs the root zone of a protected oak, which usually means exterior excavation, new drain-line trenches, or an exterior wall alteration like adding a window. If your bathroom remodel stays inside the existing footprint, no arborist report is required. If we need to run a new drain line or add exterior access, we’ll tell you during the estimate and file the tree report before rough-in begins. Call (877) 610-1318 and we’ll check your lot for protected oaks on the first visit.
Yes, almost certainly. Los Altos sits on expansive Adobe clay that swells in wet winters and shrinks through dry summers. A slab-on-grade bathroom floor that develops the same crack line after repeated tile repairs is telling you the slab is moving beneath it. We don’t re-tile over a moving slab. We evaluate the foundation, determine whether the movement is seasonal or structural, and write a plan that addresses it before new tile goes down. Call (877) 610-1318 and we’ll take a look. Free estimate, no trip charge inside the county.
No. Skipping the permit in Los Altos is a bad trade. The city’s design-review and building inspection process exists to verify that the work done behind your walls is safe and legal. An unpermitted bathroom remodel can slow a future home sale, complicate an insurance claim, and leave you with work that never passed a single inspection. We pull permits on every eligible job and get the inspections signed. The permit inspector works for you, not for me, and that’s exactly why I like him. Call (877) 610-1318 and we’ll walk you through what a permitted remodel looks like in Los Altos.
