Explore Some Of Our Featured Projects
Bathrooms are small spaces with a lot of moving parts — tile, plumbing, electrical, waterproofing, cabinetry, fixtures — all in a room where moisture and poor workmanship eventually find each other. Done right, a bathroom remodel is one of the most satisfying projects in the house. Done poorly, you're tearing it apart again in five years.

Bathroom Remodeling in LA Frequently Asked Questions
How much does a bathroom remodel cost in Los Angeles?
A guest bath refresh typically runs $15,000 to $35,000. A full primary suite renovation — custom tile, new plumbing, frameless shower, freestanding tub, new vanity — generally ranges from $50,000 to $120,000 depending on size and material selections. We provide detailed estimates based on your specific scope, not ballpark numbers that change later.
How long does a bathroom remodel take?
A straightforward guest bath remodel takes 3 to 5 weeks once construction starts. A full primary suite renovation runs 6 to 10 weeks. Lead times on custom tile, specialty fixtures, and frameless glass can affect the schedule — we factor those in upfront.
Do I need permits for a bathroom remodel?
Cosmetic work — new tile, new vanity, new fixtures in the same location — generally doesn’t require permits. Moving plumbing, adding electrical circuits, or making structural changes does. We tell you what’s required before work starts and handle all of it.
Can you add a bathroom where there isn't one?
Yes. Adding a bathroom requires rerouting plumbing drain and supply lines and almost always requires permits. It’s more involved than a remodel of an existing bath, but it’s one of the more valuable additions you can make to a home — especially if you’re converting a room or adding to a primary suite.
What's the most important thing to get right in a bathroom remodel?
Waterproofing — by a significant margin. It’s the work behind the tile that most homeowners never see, and it’s what determines whether a bathroom holds up for 20 years or starts failing in three. We use proper backer board and waterproof membrane systems on every shower and wet area, not shortcuts.
Can we expand the footprint of an existing bathroom?
Yes, if the adjacent space allows it. Expanding a bathroom typically involves borrowing square footage from a closet, hallway, or adjoining room, and requires structural and plumbing coordination. We assess the feasibility during the initial consultation.
