Bathroom Remodel in Sunnyvale

Spa-grade comfort built on what matters underneath — waterproofing, ventilation, and code-perfect plumbing — by the contractor headquartered in Sunnyvale.

A bathroom is the smallest room with the highest failure stakes in a Sunnyvale home: more water, more steam, and more code 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 Sunnyvale bathroom projects pair the 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. And because we're headquartered in the city, the small-but-frequent site visits a bath remodel needs don't slow things down.

From compact 1960s hall baths to expanded primary suites in Sunnyvale's ranch and Eichler homes, we right-size the scope to your budget and your home's resale position.

Bathroom permits in Sunnyvale

Moving or replacing plumbing, electrical, or ventilation requires a permit through Sunnyvale's One-Stop Permit Center; bath remodels typically clear in 3–6 weeks. Tile-and-vanity cosmetic swaps may not need one. We include permitting in every project — which protects resale value and your insurance coverage — and flood-test every shower pan before tile so waterproofing is provable, not assumed.

Sunnyvale Bathroom Remodeling FAQs

How much does a bathroom remodel cost in Sunnyvale?+

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 the price more than fixtures do.

How long does a bathroom remodel take in Sunnyvale?+

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

Do I need a permit to remodel a bathroom in Sunnyvale?+

Yes if you're moving or replacing plumbing, electrical, or ventilation — filed through the One-Stop Permit Center. Cosmetic tile-and-vanity swaps may not. We include permitting in every project to protect resale value and 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, flood-tested pans, and inspected rough-ins, which is why we can warranty them confidently.

Can you work around an Eichler slab in Sunnyvale?+

Yes — Eichler baths sit on radiant slabs with in-slab plumbing, which calls for careful demo and rerouting. We've done it; we protect the radiant system and design the layout around what the slab allows.
