Bathroom Remodeling in the Bay Area

Spa-grade comfort built on what matters most underneath: waterproofing, ventilation, and code-perfect plumbing.

A bathroom is the smallest room with the highest failure stakes in your home: more water, more steam, and more code requirements per square foot than anywhere else. The difference between a 5-year bathroom and a 30-year bathroom is invisible the day it's finished — membrane waterproofing, sloped pans, sealed penetrations, real ventilation.

We build the 30-year kind. Our bathroom projects pair design finishes clients love — curbless showers, heated floors, backlit mirrors, freestanding tubs — with the unglamorous systems work that protects the investment and passes inspection the first time.

What's included

Full Gut Renovations

Down-to-studs rebuilds with new plumbing, electrical, waterproofing, and ventilation.

Curbless & Walk-In Showers

Linear drains, membrane systems, and frameless glass — accessible and stunning.

Primary Suite Expansions

Borrow closet or bedroom space to create the double-vanity wet-room suite.

Heated Floors & Smart Comfort

Electric radiant floors, humidity-sensing fans, and lighting that flatters.

Aging-in-Place Design

Zero-threshold entries, blocking for future grab bars, comfort-height fixtures — invisible until needed.

Frequently Asked Questions

How much does a bathroom remodel cost in the Bay Area?+

In 2026, plan $25K–$45K for a hall bath, $45K–$90K for a full primary bath remodel, and $90K+ for expanded spa suites. Labor and waterproofing-critical trades drive Bay Area pricing more than fixtures do.

How long does a bathroom remodel take?+

3–6 weeks of construction for most baths once permits and materials are in hand. The schedule killers are tile lead times and shower glass (measured after tile, then 1–2 weeks fabrication) — we order early and sequence around them.

Do I need a permit to remodel a bathroom?+

Yes — moving or replacing plumbing, electrical, or ventilation requires a permit in every Bay Area city. Tile-and-vanity cosmetic swaps may not. We include permitting in every project, which protects resale value and your insurance coverage.

What's the most common bathroom failure you fix?+

Leaking showers from skipped waterproofing — tile set directly on drywall or unsealed pans. Our showers get membrane systems (Schluter-class), flood-tested pans, and inspected rough-ins, which is why we can warranty them confidently.

Is a curbless shower worth it?+

It's the most-requested bathroom feature of the last five years: better looking, easier to clean, and future-proof. It requires recessing the floor or building up surroundings — easy in a gut remodel, harder in a surface refresh — and we'll tell you which camp your bath falls in.
