Fast, Reliable Bathroom Remodeling Across Malibu
A full bathroom remodel in Malibu typically costs between $9,000 and $28,000, depending on square footage, the condition of the existing plumbing, and whether the home sits on the beach side of Highway 1 or further inland. Most projects run 3 to 6 weeks from demolition to final inspection. We coordinate scheduling from our Los Angeles office and send verified crews directly to Malibu job sites, from Point Dume to Malibu Park. Call (805) 309-3386 for a written quote before any work starts.
What matters here is that hiring a General Contractor in Malibu is not like working in a generic remodel market. Salt air, hillside codes, and homes built from 1950s beach cottages to glass-and-steel oceanfront estates all change what goes into the walls and under the tile. A bathroom that looks identical to one in Westlake Village may need completely different fasteners, waterproofing, and fixture specs to survive the coastal environment. We account for that from the first site visit.
Why Mason Remodeling Co Thousand Oaks Is Malibu’s Preferred Bathroom Remodeling Company

Malibu homeowners call us because we show up with a name and a face, not a mystery crew. Every technician is background-checked, identity-verified, and introduced to you by name and photo before the visit. That’s the Threshold Standard, and it’s how we’ve operated since 2004 as part of the Threshold Group family of home-service companies. When a uniformed technician arrives at your door on Encinal Canyon Road or Broad Beach, they carry a photo ID badge matching the name you already received.
We put the price in writing before a single tool is unpacked. No verbal estimates that grow on the final bill, no allowances that quietly inflate mid-project. The number you approve is the number you pay, unless you request a change in scope. And every completed bathroom is covered by our 365-Day Done Right Promise: if the work is not right within a year of completion, we make it right at no cost. Isaac Pruett, who leads our team, stands behind that promise personally.
Malibu customers also benefit from what we stock and specify. We work with specification-grade lines like Kohler, Moen, Toto, and Grohe, plus Cambria and Silestone surfaces. That access matters when you’re choosing a vanity faucet that will not seize from salt air in three years, or a shower valve with stainless internals that survives Point Dume’s marine fog.
Styles & brands we work with







Bathroom Renovation in Malibu
Bathroom Renovation in Malibu means working backwards from the environment: salt fog off the Pacific, seasonal Santa Ana winds, and wildfire-resistant building requirements that shape what local code will approve. A renovation typically includes demolition of the existing bathroom, rough-in plumbing and electrical updates, waterproofing, tile or solid-surface installation, vanity and fixture install, and finish trim. On beachside homes, we often find that the original rough-in plumbing and the venting were never designed for coastal exposure, and the renovation has to correct those failures before cosmetic work begins.
Coastal-Grade Waterproofing and Ventilation
Malibu bathrooms on seaward walls pull salt-laden air through poorly vented bath fans, which corrodes wiring and rots rough-in framing. We specify sealed, direct-vented fans and marine-rated duct connections, then install a Schluter waterproofing system behind tile and at all transitions so moisture never reaches the framing. This is not an upsell option. It is the minimum that works here.
Ocean-Resistant Fixture and Trim Specification
Standard brass P-traps and supply stops turn green and seize within a few years on beach-side remodels. We specify fixtures with stainless internals and marine-grade trim finishes, like Moen Align or Kohler’s brushed stainless lines. The material cost runs 15 to 25 percent above what the same renovation would use in Calabasas, and it is the difference between a bathroom that still shuts off cleanly in year eight and one that needs the vanity pulled out to replace a seized valve.
Small Bathroom Remodel in Malibu

A Small Bathroom Remodel in Malibu, like a guest bath, powder room, or compact hall bath, runs $5,000 to $12,000. These jobs make up a large share of our Malibu work because many canyon and beach-cottage homes were built with bathrooms under 40 square feet, and the challenge is fitting current code-compliant clearances into a footprint that never anticipated them. Small does not mean simple. A 1950s Las Flores Canyon bathroom often hides corroded galvanized supply lines, a subfloor with unvented moisture damage, and a toilet flange that has been “fixed” with wax rings twice.
Compact Vanity and Storage Replacement
On bluff-top and hillside lots, a swollen vanity base from ocean humidity is common. We replace it with a vented cabinet base that allows air movement under the cabinet, not trapped against the floor. If the cabinet style works with the home’s mid-century character, we can often keep the original door and drawer faces and rebuild the box with marine-grade plywood.
Water-Damaged Subfloor Repair
Under every small Malibu bathroom we open, someone expects rot around the toilet flange. What surprises homeowners is how often the rot extends under the tub or along the shower curb. We cut out the damaged section and replace it with marine-grade plywood, then run the waterproofing up the wall and under the new finish floor so the same failure never recurs. That single repair typically adds $800 to $1,500 to the project and it is the cheapest part of the remodel compared to what deferred rot costs later.
Trusted Brands We Service in Malibu
We service and install fixtures and surfaces from Kohler, Moen, Toto, Grohe, Cambria, Silestone, and Caesarstone, and we stock replacement hard parts common to Malibu’s bathroom stock: stainless supply stops, marine-grade P-trap assemblies, and Schluter waterproofing materials. If you have a vanity from CGI, CWS, or ES Windows that needs integrated bathroom work around it, we can coordinate the surrounding remodel without voiding the original manufacturer’s spec. Having those parts locally available means faster turnarounds for Malibu customers who do not want a half-finished bathroom waiting on a backordered trim kit.
Common Bathroom Remodeling Problems We See in Malibu Homes
- Salt pitting on unsealed stone. Travertine and marble in ocean-view bathrooms develop pitting and efflorescence within a few years. Grinding or replacing the stone is the only real fix, and it is a cost that an inland spec never anticipates. We seal or avoid those materials on seaward-exposed surfaces from day one.
- Seized shutoff valves. Brass supply stops and P-traps on beach-side remodels turn green, then seize, then fail exactly when a toilet or vanity needs service. We specify stainless internals and marine-grade trim so shutoffs still work a decade later.
- Rotted subfloors around toilet flanges. Salt fog creeps through vent gaps and unsealed wall penetrations, condenses inside the wall cavity, and rots the rough framing. By the time the toilet rocks, the subfloor is often gone. We replace with marine-grade plywood and correct the ventilation path.
- Unpermitted previous work on hillside homes. Many hillside Malibu homes have bathrooms with relocated drains or unvented waste lines from past remodeling attempts that never pulled permits. That work fails inspections and leaks over time. We handle permit-ready corrections and the inspections that follow.

AfterPricing for Bathroom Remodeling in Malibu, CA
Bathroom remodeling in Malibu runs above Los Angeles County averages because the coastal and hillside codes, marine-grade material requirements, and access challenges add real labor and material costs. A mid-range full bathroom remodel runs $14,000 to $22,000. Higher-end oceanfront master baths with custom glass, heated floors, and slab stone run $24,000 to $28,000 and up. Here is the line-item reality:
| Project Type | Malibu Price Range |
|---|---|
| Bathroom Remodel | $9,000 – $28,000 |
| Small Bathroom Remodel | $5,000 – $12,000 |
| Walk-In Shower Installation | $4,500 – $12,000 |
What moves the price: whether the home is beach side or inland, the condition of the existing drain lines, whether a vanity or toilet is being relocated (which triggers plan check and permit fees on hillside lots), and whether the finish specs call for marine-grade metals and solid surfaces. Call (805) 309-3386 for a free estimate and a written line-item quote before any work starts.
One honest note about the Malibu price gap. The cheap inland spec, the one that quotes $6,000 for a coastal bathroom, fails within 3 to 5 years. Salt air pits the stone, seizes the valves, and rots the subfloor around the flange. The coastal spec costs more up front and less by year six, because you are not paying a second remodel to fix the first one.

FAQs About Bathroom Remodeling in Malibu
Yes, beachside homes in Malibu fall under coastal zone requirements that mandate corrosion-resistant materials for exposed plumbing and fasteners, and local inspectors commonly reject standard galvanized or non-marine-grade steel in sea-air exposure. We specify stainless steel supply stops, stainless P-trap assemblies, and marine-grade mounting hardware on every beach-side bathroom we touch. The code section varies by zone, so call (805) 309-3386 and we will check your specific parcel before the permit submittal.
Because the environment and the inspection process are different. Salt air forces stainless internals, sealed waterproofing systems, and direct-vented fans that inland code does not require. Hillside and bluff-top homes often need geotechnical sign-off or plan check for any drain relocation. And access on narrow canyon roads or beach-side streets adds delivery and staging time. The difference is typically 20 to 40 percent above a comparable Thousand Oaks remodel, and the coastal spec is what keeps the job passing inspection year after year. Call (805) 309-3386 for an exact quote on your street.
Stop the water source first, whether that is a leaking supply line, a failed wax ring, or condensation from unvented cabinetry. Then replace the damaged base with marine-grade plywood or a vented cabinet design that allows airflow under the unit. Swelling does not reverse, and painting over it locks moisture in. We can match the existing door and drawer faces to preserve the home’s character while rebuilding the box to survive Point Dume’s marine layer. Call (805) 309-3386 and we will assess the damage in person.
Yes. Any drain relocation on a hillside lot in Malibu generally requires a plan check and possibly a geotechnical or structural review because of slope stability and soil conditions. Unpermitted drain moves are the single most common reason a remodel fails its final inspection here. We pull permits, file the plan check, and coordinate the required inspections as part of the written quote, so you are not handling city submittals on your own.
On Point Dume and other bluff-top parcels with limited beach access, materials are often staged at the nearest legal drop point and delivered by barge or crane. The logistics add time and cost to the project, and we plan the material take-off carefully so nothing gets left back at the staging lot. This is where a written, fixed price protects you: the staging and access costs are accounted for before the job starts, not billed as a surprise line item on week four.
