Hollywood Hills Bathroom Remodeling in Los Angeles

The bathroom that sits above something expensive

That is the defining fact of a Hollywood Hills bathroom. In a stepped or cantilevered house, the bathroom is usually above a living room with a beam ceiling, above a bedroom, or above the garage, and in many of these houses the ceiling below cannot be opened up and patched invisibly. So the waterproofing is not a detail. It is the reason to hire a licensed contractor for the job at all.

Fix Brothers is a licensed remodeling contractor owned by two brothers and operating out of Chatsworth since 2015. The same people who quote your bathroom build it, and we meet the inspector ourselves.

How we waterproof, in order

A sloped base, built to fall properly to the drain rather than relying on the tile to do it. A bonded sheet or liquid membrane carried up the walls and over the curb, with inside corners reinforced. The drain assembly tied into the membrane rather than sitting next to it. Niches framed and waterproofed as part of the assembly, not cut in afterward. Then a flood test held overnight and checked from below where there is access, before a single tile goes down. If the test does not hold, it gets fixed then, which is the only cheap moment it will ever be.

Access decides the schedule

Substandard streets, blind curves, nowhere legal for a dumpster, a driveway too steep for a dolly and a stair run from where a truck can stop to where the bathroom is. That is normal here, and it decides real things: whether a cast iron tub leaves whole or cut into pieces, whether a freestanding tub or a large stone slab needs a lift, how debris leaves, and how much of each day is carrying rather than building. We drive and measure the route at the first visit, price it as its own line and arrange a street-use permit or a temporary no-parking zone where one is needed.

What the age of the house brings with it

• 1920s houses: galvanized supply lines, cast iron waste with rust at the closet bend, lath and plaster, and knob and tube wiring near the vanity.
• Mid-century houses: original tiled counters, single-pane windows, a tub that was never intended to be a shower, and a fan that vents nowhere useful.
• Any age: subfloor and joist rot where the tub apron met a grout line that failed years ago.
• Upper levels: a stain in the ceiling below from an earlier leak, usually painted over rather than investigated.
• Exterior walls: stucco and flashing failures at the bathroom window, letting water into the framing.

We open targeted holes before quoting, look from below where access allows, and carry a stated repair allowance so neither of us is surprised in week two.

Ventilation in a house with no attic

A bathroom with a beam ceiling above it has nowhere obvious to run a duct. The answer is a wall termination or a short routed run through a chase, properly insulated so it does not condense inside the assembly. What we will not do is install a fan that discharges into a cavity, which is how framing in these houses gets quietly ruined. The termination point gets decided at the planning stage.

Permits and hillside review

The Hollywood Hills are in the City of Los Angeles, so permits come from LADBS. Swapping a vanity, a toilet and tile in place generally counts as maintenance. Relocating a drain, converting a tub to a shower, adding circuits, changing a window or opening a wall needs a permit. Bathroom work is usually issued without a full plan check, but once the project touches the exterior or the structure, hillside review comes into it, and much of the area carries a Very High Fire Hazard Severity Zone designation that governs exterior materials and vent screening. In the Mulholland corridor a specific plan adds design review. We check the address and tell you which category you are in.

Steam, spa fixtures and the things that need planning

A lot of these bathrooms get a steam shower, a large rain head, body sprays or a freestanding tub with a floor-mounted filler. Each one has a requirement behind the finish. Steam needs a sealed enclosure, a sloped ceiling, a vapor-tight assembly and a generator with access for service. Multiple shower outlets need the water supply and the drain to carry them, which we measure rather than assume. A floor-mounted filler needs the supply roughed in exactly, because it cannot be moved afterward. We settle all of it at the rough stage.

How the job runs, and how long

• Walkthrough with exploratory openings, a look from the room below and the access route driven and measured.
• Written line-item scope with tile, fixture and glass allowances, a stated repair allowance and access priced openly.
• LADBS permit, with hillside or specific plan review where it applies.
• Dust containment, demolition, framing and subfloor repairs.
• Plumbing, circuits and ventilation roughed in to the fixtures actually specified, then inspection.
• Waterproofing, an overnight flood test checked from below, then tile, glass and fixtures.
• Final inspection and a punch-list walkthrough while we are still set up.

Plan on four to eight weeks of construction once permitted. Shower glass gets templated once the tile is finished and comes back a week or two later, which is the step most schedules leave out.

Work you can look at

Look at a bathroom taken back to the studs and rebuilt and a walk-in shower built into a small room. For what a leak does to a ceiling below and how it is put back, see whole ceiling restoration after a penetration and wall and ceiling restoration after a leak.

My bathroom is above the living room. What protects the ceiling below?

The waterproofing assembly, and the flood test that proves it. We build on a properly sloped base with a bonded sheet or liquid membrane carried up the walls and over the curb, reinforced corners and the drain tied into the membrane, then hold water in it overnight and check from below where there is access. In a house with a beam ceiling downstairs, that test is the whole point.

Why does access cost so much on these streets?

Because material has to be moved by hand or by shuttle. Substandard streets, blind curves, no legal dumpster spot and a driveway too steep for a dolly mean a cast iron tub may have to be cut out in pieces and a freestanding tub or stone slab may need a lift. We drive and measure the route at the first visit and price it as its own line rather than hiding it.

Can I have a steam shower?

Usually yes, if it is planned at the rough stage. Steam needs a fully sealed enclosure, a sloped ceiling inside the shower, a vapor-tight assembly behind the tile and a generator located where it can be serviced. Added as an afterthought it leaks vapor into the framing. We decide the enclosure, the generator location and the door detail before any tile is ordered.

Does a bathroom remodel trigger hillside review?

Not if it stays inside the existing walls, which most do. It can once the work reaches the exterior or the structure: a new or enlarged window, a relocated vent termination, a bump-out or anything structural. Much of the area is also in a Very High Fire Hazard Severity Zone, which governs exterior materials and vent screening. We check your address before scoping.

How long will the bathroom be out of service?

Four to eight weeks of construction after the permit, with the range driven by how far pipe replacement reaches and how difficult access is. Custom shower glass is measured once tile is set and takes another week or two, so the room can look finished before it is usable. The estimate lists dated phases so you can plan around it.
