Spa bathrooms, walk-in showers, master suites — scoped in minutes.
What does bathroom remodeling actually cost in LA in 2026?
Bathroom remodeling in Los Angeles ranges from $25,000-$85,000 for standard projects in 2026, with luxury spa bathrooms exceeding $150,000. Most homeowners spend $35,000-$55,000 on a primary bathroom renovation taking 5-10 weeks. The scope spans $8K powder room refreshes to $150K+ luxury spa suites including wet-rated backlit onyx and quartzite for shower walls and vanity tops. A full-service LA bathroom project must coordinate Title 24 ventilation, curbless shower code compliance, heated radiant floor requirements, steam shower waterproofing, wet-location LED specifications (IP67/IP65), universal design, and LADBS permitting under one design-build contract with NP Line Design (CSLB #1105249). Waterproofing is where most LA bathroom projects fail - moisture works through grout within 5 years when contractors skip proper Schluter or Wedi board systems.

What homeowners miss that costs them money
- ⚠Waterproofing failure is the #1 LA bathroom defect - drywall behind tile instead of Schluter/Wedi lets moisture through grout within 5 years
- ⚠Greenboard is prohibited in wet areas - cement board plus waterproof membrane is required, especially for steam
- ⚠Pre-1994 plumbing trigger - any bathroom plumbing permit forces whole-house low-flow fixture replacement (often discovered mid-project)
- ⚠Built-in shower niches cost $150-$300 each during construction and can't be added later without demolishing finished tile
- ⚠Low-flow showerheads combined with low household water pressure compromise shower performance - test pressure before specifying flow rates

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon's rim.
He wasn't the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily's contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily's beads.
That's what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner's real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That's our vibe too.
