Custom bathroom remodels built around you — from walk-in showers to full spa retreats. Serving San Jose and the greater Bay Area.
In the Bay Area, your bathroom works harder than almost any room in the house — and it’s one of the first things buyers judge. But a lot of Bay Area homes are stuck with bathrooms that no longer fit how people live: cramped layouts, water damage hiding behind old tile, and finishes that date the whole house. At California Bay Builders & Remodeling, we build bathroom remodels across the Bay Area that fix the daily frustration and protect your biggest investment at the same time — every one handled by one dedicated design-build team, start to finish.
The problems a bathroom remodel solves:
•A tub you never use eating half the room — converting an unused tub into a large walk-in shower instantly makes the space feel bigger, more modern, and easier to live in. One of the highest-impact changes we make.
•Water damage and leaks hiding behind the tile — older Bay Area bathrooms often have failed waterproofing, rot, or mold behind the walls. We tear it back to the studs, fix it right, and waterproof it to last — not just cover it up.
•A cramped, badly-planned layout — a poorly placed vanity, door, or shower can waste the whole room. We rework the layout so the space actually functions, even when the footprint stays the same.
•Not enough storage — smart vanities, recessed niches, and built-in storage designed around what you actually keep in your bathroom, so the counters stay clear.
•Dated finishes dragging down your home’s value — new tile, vanities, fixtures, and lighting that bring a tired bathroom up to today’s standards and match what the rest of your home is worth.
•Aging in place — curbless showers, grab bars, and accessible layouts that let you or your parents stay in the home safely for years to come.
Every bathroom we remodel across the Bay Area is fully custom — but most homeowners start with one of these three directions. Whether you want a sleek modern bath, a spa-inspired retreat, or a timeless classic look, we design and build it around your home. Find the style that feels like yours.
Modern, spa, or classic — whichever direction you lean, every bathroom California Bay Builders & Remodeling builds across the Bay Area is fully custom and designed around your home. Not sure which fits? That's what the free consultation is for.

Here’s where California Bay Builders & Remodeling bathroom pricing starts. Every price is a starting point — the final number depends on the size of your bathroom, how much you’re moving, and the finishes you choose, and it comes to you as a detailed, line-item proposal before you commit.
| Bathroom Size | What It Involves | Starting At |
|---|---|---|
| Small Bathroom | Full remodel in a compact footprint | Starting at $23,500 |
| Medium Bathroom | Full remodel with a new layout and finishes | Starting at $30,000 |
| Large Bathroom | Full remodel, bigger space with more detail | Starting at $40,000 |
| XL Primary Suite | Full custom build, high-end finishes throughout | Starting at $60,000 |
Most bathroom remodels run 4–6 weeks, with larger baths taking 5–8 weeks and a full XL primary suite up to 10 weeks. Timelines depend on the size of your bathroom, whether you're moving plumbing or walls, and how long finishes take to arrive. During your consultation, California Bay Builders & Remodeling will give you a realistic schedule for your specific project — not an optimistic one designed to win the job.

Have questions about your bathroom remodel? Give us a call — we’ll walk you through it, no pressure.
From the first call to the final walkthrough, here's exactly how California Bay Builders & Remodeling brings your Bay Area bathroom to life — one team, one project manager, one point of accountability.
We walk through everything together. Our experienced project manager brings fresh ideas to the table, and together we shape the perfect bathroom for your home and how you live.
Once we agree on all the terms and milestone payments, we meet again — this time with our in-house designer. Your project manager gives the designer a full recap, and you bring your idea book to the meeting. The designer asks the additional questions, takes measurements, and gets to work on your design.
After you approve your design, we submit your project to the city and pull the permit for you — the permit card is yours. Most bathroom remodel permits are over-the-counter, so if there's no major structural change, we often get same-day approval.
You meet our trusted showroom partner to select your tile, vanity, and fixtures based on your design. They guide you through every choice and deliver everything to your home, coordinated with our schedule.
We believe every great project is decided before demolition. We make sure everything is ready and on-hand — preventing delays and inconvenience. On day one, we protect your home and work area with ram board, plastic, and zip walls. Our crew cleans every day, but it's still a job site, so we cover it right. Only after proper prep do we start demo.
Demolition, then construction — with full waterproofing taken back to the studs, and city inspections signing off along the way, so every phase is done to code and verified at each stage.
We walk the punch list to get every detail right, then bring in our professional clean crew so your bathroom is spotless and move-in ready.
You've got a brand-new bathroom, designed and built to last. We'll take a picture together.

Most homeowners don't have tens of thousands sitting in the bank — and you don't need to in order to remodel your bathroom in the Bay Area.
The problem with traditional financing is the equity wall: standard loans only lend against what your home is worth today, not what it'll be worth after your project is complete. That's why California Bay Builders & Remodeling partners with RenoFi.
A RenoFi HELOC lends against your home's after-renovation value — what your property will be worth once the work is done — so you can access far more than a traditional loan allows. And it's not just for bathrooms: use it across all our design-build services, from your bathroom and kitchen to a custom ADU or whole-home remodel.

A bathroom is the most code-sensitive room in the house — plumbing, ventilation, and water efficiency all have to meet strict California standards. We handle every bit of it for you.
When you need a permit. Nearly every bathroom remodel requires one — any work that touches plumbing, electrical, or moves fixtures has to be permitted and inspected. California Bay Builders & Remodeling pulls and manages your permit for you, so you never have to chase a plan checker or decode a city requirement.
Water efficiency (CALGreen). California's Green Building Standards Code sets strict limits on bathroom fixtures — toilets capped at 1.28 gallons per flush, low-flow faucets, and efficient showerheads. Every fixture we install meets or exceeds current California water-efficiency standards, so your new bathroom is compliant, efficient, and built for California's water reality.
Lighting & ventilation (Title 24). The state's Building Energy Efficiency Standards (Title 24) require high-efficacy lighting and proper exhaust ventilation in every remodeled bathroom — critical for controlling the moisture that destroys Bay Area bathrooms. These standards are set by the California Energy Commission, and the current 2025 code took effect January 1, 2026. We build to them from the start, so your bathroom passes inspection the first time.
Bottom line: from permits to water efficiency to ventilation, your bathroom has to be built to code — and that's on us, not you. We manage permits, inspections, and full California code compliance as part of every bathroom remodel. Get a free consultation and we'll walk you through exactly what your project needs.
