Bathroom Remodeling Contractor Los Angeles

Bathroom remodels in LA start at $18,000 for a guest bath, $28,000 for a mid-range full remodel, and $58,000 and up for a master suite, depending on size, whether fixtures move, and the tile and fixture selections.

Typical cost: From $18,000 (guest bath), $28,000 (mid-range), $58,000+ (master suite)
Typical timeline: 3–5 weeks of construction
Permits: Permits and inspections handled by us through LADBS or your city building department.
Service area: All of Los Angeles County, including the San Fernando Valley, Westside, South Bay and foothill cities.
Credentials: Licensed, bonded and insured. CSLB #1076428. Owner-operated.

What We Do

Full gut renovations, primary bath suites, guest baths and powder rooms. We do the waterproofing ourselves and don't hide it behind someone else's schedule.

Curbless and custom tile showers
Freestanding and drop-in tubs
Custom vanities and storage
Heated floors and niche lighting
Full waterproofing assemblies
Exhaust ventilation sized to the room

The Part Nobody Sees

Waterproofing is the single most important part of a bathroom, and it's the first thing a cheap bid cuts. We install a complete waterproofing assembly behind the tile, slope the pan correctly, and pressure-test before anything gets covered up.

Sheet or liquid membrane behind all wet walls
Properly sloped, tested shower pans
Backer board instead of drywall in wet areas
Sealed penetrations at valves and drains

Permits and Timeline

Relocating fixtures or adding circuits needs a permit. Most bathrooms run 3 to 5 weeks of construction once materials are on site. The schedule slips when tile and fixtures are ordered late, so we lock selections before demo.

Plumbing and electrical permits through LADBS
Selections finalized before demolition
Daily photo updates in your client portal
