Fast, Reliable Bathroom Remodeling Across Malibu
A full bathroom remodel by a General Contractor in Malibu typically runs $9,000 to $28,000, and the two things that drive that number are the scope of the work and the materials you choose. Lead times on custom cabinetry, architectural glass, and specialty stone set the calendar far more than labor does. Call Penhallow Remodeling at (936) 259-2607, and we’ll give you a written price before a single tile is pulled.
We’ve worked in Point Dume, Topanga Canyon, the Colony, and the hillside lots above Pacific Coast Highway. That matters here more than it does in most places, because a Malibu bathroom remodel sits at the intersection of two regulatory regimes that most contractors never contend with. Trevor Nash runs our crews, and he’ll explain exactly what your project triggers, what it costs, and what the schedule looks like, in plain English, before anything gets ordered.
Why Penhallow Remodeling Is Malibu’s Preferred Bathroom Remodeling Company
We show up in a real arrival window, with background-checked, uniformed technicians. A live person answers our phone 24/7, so when you call at 7 a.m. on a Tuesday to ask about a shower valve spec, you talk to a person, not a voicemail tree.
The Malibu homes we work in are not tract houses. They’re 1940s and 50s beach cottages on post-and-piling foundations over sand, or custom builds cantilevered into hillside pads. A bathroom rough-in in a Colony beach cottage is a different job than a bathroom rough-in on a Point Dume bluff. We know both. Our local reputation in Malibu is built on coordinating with the Coastal Commission and the fire marshal’s Wildland-Urban Interface requirements without making the homeowner manage the paper trail.
Trevor Nash sets the standard on every job: a written price before work starts, a written guarantee that the work is done right, and a crew that leaves the site cleaner than they found it. That’s The Kingswell Way, and it’s been operating since 2004.
Walk In Shower in Malibu
A walk-in shower in Malibu is rarely just a shower replacement. It’s often the centerpiece of a remodel that opens a cramped 1970s bathroom into something useful, which is why the job costs between $4,500 and $12,000 depending on glass, waterproofing, and whether we’re re-framing walls or relocating drains. In Malibu specifically, changing the fixture count or expanding the footprint can trigger a septic system evaluation, because Point Dume, Topanga Canyon, and large parts of the hillside above PCH have no municipal sewer connection.
Frameless glass and marine conditions
Salt air on beachfront and bluff-edge properties corrodes cheap hardware fast. We spec marine-grade fasteners and hardware on anything within sight of the Pacific, and we’ve installed frameless glass enclosures that hold up to the moisture load of a beach house bathroom without clouding or pitting within a few years.
Waterproofing before tile
We build the substrate, the moisture-resistant layer behind your tile, before we ever set a single piece of stone. On older Malibu bathrooms, the original substrate is often drywall, which is why we see failures in showers that were “remodeled” a decade ago by someone who skipped this step. We don’t skip it.
Our Bathroom Remodeling team handles walk-in showers, tub-to-shower conversions, and full bath renovations with the same written-price standard on every job.
Bathroom Remodeling Companies in Malibu
Bathroom remodeling companies in Malibu fall into two camps: those who understand Coastal Commission permits and WUI fire code, and those who don’t. Penhallow Remodeling is in the first camp. A full bathroom remodel here runs $9,000 to $28,000, and the variance comes from cabinetry line, countertop material, and whether the project adds square footage or changes the fixture count. Most Malibu homeowners we talk to have already been burned once, by a contractor who gave a verbal estimate that changed after demo day. We put the number in writing before work starts.
Designer and architect coordination
On high-end Malibu jobs, we work directly with your architect and designer, not around them. We’ve sequenced shower valve rough-ins around Coastal Commission inspection windows on Point Dume, and we’ve coordinated custom white-oak vanities with a homeowner’s own designer. The schedule bends to the review timeline, not the other way around.
Written price, fixed number
The number we write down before ordering is the number on the invoice. That means when we spec a Cambria quartz top or a Kohler fixture, the price of that material is locked before it ships. If a cabinet line has a twelve-week lead time, we tell you that on day one, and the price doesn’t move because the lead time did.
When you’re comparing bathroom remodeling companies in Malibu, ask each one whether their price is written or verbal, and whether they’ll pull the Coastal Development Permit themselves.
Trusted Brands We Service in Malibu
We install materials from recognized trade brands, including KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, and Kohler and Moen fixtures. Some Malibu clients want the look of a panelized factory build, and we’ve referenced Abodu and Dvele for inspiration on clean, modern lines without sacrificing the beach house feel. We maintain strong relationships with local supply channels in the Malibu area, which means we can often source replacement parts and hardware faster than a contractor who works primarily inland.
Common Bathroom Remodeling Problems We See in Malibu Homes
- Septic-triggered remodels. A bathroom that adds a fixture or changes the footprint in Point Dume or Topanga Canyon can legally require a full septic system evaluation. The same work in Pacific Palisades or Santa Monica never touches a septic tank.
- Salt-spray corrosion. Beachfront and bluff-edge bathrooms get moisture and salt air that eat uncoated steel and cheap hardware. We use marine-grade fasteners and corrosion-resistant finishes anywhere near the water.
- Original drywall substrate. On 1950s and 60s beach cottages, we regularly open shower walls to find drywall behind the tile, not cement board. That’s a failure waiting to happen, and it’s why we strip to the studs on most Malibu shower remodels.
- WUI code conflicts. Fire-resistant construction requirements can dictate which cladding or venting materials you’re allowed to use, which changes both the scope and the budget on hillside homes. We know the code well enough to price it correctly the first time.
Pricing for Bathroom Remodeling in Malibu, CA
A bathroom remodel in Malibu runs $9,000 to $28,000. A small bathroom remodel sits at $5,000 to $12,000. A walk-in shower installation alone is $4,500 to $12,000, and a tub-to-shower conversion is $3,500 to $10,000. What drives the spread: custom cabinetry, stone or quartz countertops, frameless glass, and the structural work that older Malibu homes so often need once walls open up. Septic evaluations, when triggered, are a separate line item, and Coastal Development Permit fees vary by project.
