What does a bathroom remodel cost in Malibu in 2026?

Malibu bathrooms run $33K–$112.2K in 2026 — 32% Ultra tier. Most 90265 primary bathroom remodels land $41K–$84K. Powder rooms refresh $9K–$18K. Full luxury spa builds with steam, heated floors, and curbless shower clear $140K. Hillside lots add another 5–10% for tighter staging. VHFHSZ-zoned parcels rarely see bathroom-scope fire surcharges unless exterior work is involved. Coastal-zone surcharge hits only when exterior envelope changes trigger CDP review. Tile and stone eat 25% of any budget.

Does Malibu use LADBS for bathroom permits?

Malibu runs its own permit counter — not LADBS. Like-for-like fixture swaps usually clear fastest; plumbing relocation, electrical upgrades, tub-to-shower, curbless shower, heated floors, or steam showers pull standard plan check at 6–10 weeks. Most real 90265 bathroom remodels hit at least one of those triggers. Parcels in the coastal zone with exterior bathroom changes add Coastal Development Permit review (4–8 weeks).

What's the waterproofing code for Malibu bathrooms?

Schluter DITRA or Laticrete membrane over cement board is required in Malibu. Greenboard is prohibited in wet areas — no exceptions. Curbless showers require a max 1/2-inch threshold, 1/4–1/2 inch per foot slope, waterproof liner extending 12 inches beyond the shower footprint, and a 24-hour flood test pre-tile per CBC. City of Malibu inspectors verify the flood test with the pan still wet. Proper membrane runs $800–$1,500 installed.

How long does a bathroom remodel take in Malibu?

Construction 4–10 weeks — primary bathroom 5–10, guest 4–8, powder room 1–3, luxury spa 6–12. City of Malibu plan check 6–10 weeks. Design and fixture selection add 6–12 weeks upfront. Custom stone slabs and imported fixtures can push lead time to 10–20 weeks. Typical 90265 project elapsed: 20–34 weeks.

What does Title 24 require on Malibu bathroom ventilation?

Title 24 requires bath fans at 50 CFM demand or 20 CFM continuous, Energy Star rated, max 1.0 sone, with a 4-inch minimum duct to the exterior and a humidistat set 50–80% RH. Long duct runs common in older 90265 ranch and bungalow stock reduce effective CFM — the install has to deliver spec at the grille, not at the fan. City of Malibu inspectors verify with a flow hood at rough-in.

Will my pre-1994 Malibu home trigger whole-house plumbing replacement?

Yes, if the bathroom pulls a plumbing permit. California's pre-1994 rule forces low-flow fixture replacement across the whole house — toilets, showerheads, faucets — whenever you pull a plumbing permit. Most single-family housing stock in this area predates 1994. 90265 homes typically have 10–18 fixtures, so add $3K–$8K. Swap fixtures before pulling the bathroom permit to sidestep the mid-project hit.

What makes a luxury spa bath in Malibu different from a standard remodel?

Spa bath in 90265 adds a steam shower ($3K–$8K extra), heated radiant floor ($8–$15/sqft, under 2kW per zone with 30-minute auto-off per Title 24), backlit onyx or quartzite ($3K–$45K), wet-rated IP67 LED, and curbless entry. Scope jumps from $41K–$84K standard to $140K+ spa. Steam vapor destroys drywall in 3–5 years without cement board and proper membrane.

What's different about a Malibu bathroom remodel vs. Agoura Hills?

Jurisdiction — City of Malibu for Malibu, City of Agoura Hills for Agoura Hills, price tier 32% Ultra vs 10% Valley Premium. Malibu has coastal-zone exposure. For a pure interior bathroom remodel, Title 24 ventilation and Schluter waterproofing are identical. Baily factors both jurisdictions' plan-check cadence and any overlay review into the scoping pass so your timeline reflects the actual permit path, not a generic LA average.

“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

Origin

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.
