Master bathroom remodeling in Los Angeles plans the largest bathroom in the home as one room: the layout, the shower, the tub, and the vanity decided together, not one piece at a time. It suits a primary suite where two people share the room and the storage, the lighting, and the entry all have to work at once. Call for a free written estimate, or compare complete bathroom remodeling. Our planning guide walks through the five decisions that shape a primary suite.
Master Bathroom remodeling Los Angeles CA means tearing a dated bathroom down to the studs and rebuilding it watertight, code-correct, and worth showing off. We handle the whole job: demolition, plumbing, waterproofing, tile, glass, and electrical. Whether you own an older bungalow or a condo in Culver City, we plan the work to the code that applies, and hand you a bathroom that survives decades of daily showers.
Master Bathroom remodeling Los Angeles CA is the full rebuild of your primary bathroom: new shower pan, new valve, new tile, new vanity, new lighting, and new ventilation. We strip the room to the framing, replace any rotted wood, run new PEX piping and ABS drain lines, then set cement backer board and a waterproof membrane before a single tile goes down. The result is a bathroom that drains correctly, vents correctly, and holds up to Los Angeles hard water and decades of use.
Most Los Angeles bathrooms we open up were last touched in the 1980s or 1990s. That means failing grout, a leaky shower pan, cracked tile, and outdated plumbing behind the walls. If you have been searching for a master bathroom renovation in Los Angeles, the fix is not a cosmetic patch. We rebuild the wet zone properly, with the scope agreed in writing before work starts.
Our standard master bathroom package covers the full wet zone, the plumbing behind it, and the finishes you see. Fixture upgrades, layout changes, and added square footage are quoted separately after the walkthrough so there are no surprises mid-job.
We remove the old tub, tile, vanity, toilet, and mirror, then haul it all off. Floors and doorways get protected before the first hammer swing. If there is a cast iron tub, we cut it into pieces so it comes out without damaging the door frame.
New PEX supply lines, a new shower valve, and ABS drain pipe sized to California code. We replace failing lines while the walls are open. A pipe wrench and plumber's snake come out for the drain work, and the rough-in gets inspected before anything closes.
Cement backer board, thinset mortar, and a bonded waterproof membrane over the shower pan and walls. Before installing bathroom flooring, we conduct a shower pan flood test when required to check for leaks. The test is maintained for the required period, typically 24 hours under applicable California plumbing code requirements, and the results can be documented with photos and project notes. This is the step that prevents water damage, mold and mildew, and the leaky shower pan problem that starts most remodels.
Porcelain tile, ceramic tile, natural stone, or glass mosaic, cut with a wet saw and set with a notched trowel. Grout goes in with a float, then gets sealed. We keep joints consistent and check for lippage with a laser level before we call it done.
Vanity cabinet set level with a stud finder and screw gun, quartz countertop templated and installed, sinks and faucets connected and tested. Low-flow toilet set and checked for a tight seal at the flange.
Frameless glass measured and installed, recessed lighting wired to code, and a properly sized exhaust fan vented to the exterior. Poor ventilation is why so many Los Angeles bathrooms grow mildew. We fix the cause, not just the symptom.

Every job starts with a free written estimate after we see the room.
We walk the bathroom with you, measure the footprint, and check what is behind the walls where we can. You get a written scope with fixtures, tile, and the layout, agreed before work starts.
Floors get rosin paper and ram board, the doorway gets a dust wall, and the rest of the home stays protected. Permit questions are confirmed before work begins, and selections are locked into the written scope.
Out comes the tub, tile, vanity, and toilet. We open the walls, address any structural rot, and run new supply piping and drain lines, and the shower valve is set to the agreed position before anything closes.
Cement backer board goes up, then the waterproof membrane, then a flood test on the shower pan. Tile setting starts after that passes, with joints kept consistent and grout sealed.
Frameless glass, vanity, countertop, mirrors, lighting, and the low-flow toilet go in. We caulk with silicone at every wet joint, test the shower, and walk the room with you before handing over the warranty.
Purpose-built equipment, used by trained technicians — so the job is done accurately the first time.
Precision cuts on porcelain tile, ceramic tile, and natural stone. A wet saw keeps the cut edge clean and controls dust, which matters when we are cutting inside an occupied home.
Cutting out old tubs, subfloor, and nailed framing in tight spaces. The multi-tool gets into corners where a full-size saw will not fit without damaging adjacent surfaces.
Setting tile courses, vanity height, and lighting lines dead level. The stud finder locates framing for grab bar blocking and vanity mounting before we drill.
Shower valve replacement, drain work, and clearing the line before we reconnect. We clear the drain while the wall is open so a slow drain does not become your problem after tile.
Silicone caulk at wet joints, grout spread evenly with a float, and thinset combed with a notched trowel for full tile coverage. Coverage is what prevents hollow spots and cracked tile.
Cement backer board, vanity cabinet, and trim installation. Consistent screw depth keeps the backer board flat so the waterproof membrane bonds without bumps.
Most master bathrooms we open up have at least one hidden problem behind the tile. Here are the ones we see most, and what happens if they are left alone.
Ask a pro →We remove the failed pan, replace rotted framing and subfloor, then rebuild with cement backer board and a bonded waterproof membrane. A flood test held for the required period, typically 24 hours under applicable California plumbing code requirements, checks the pan before tile goes down.
We strip the old tile, check the substrate for movement, and reset on a properly prepared surface with thinset mortar. Grout gets sealed after curing, and we use silicone caulk at every change of plane instead of grout.
We replace supply lines with PEX piping and install a new pressure-balancing shower valve. Drain lines get upgraded to ABS where needed, and we test temperature and pressure before we close the wall.
We size the exhaust fan to the room volume, vent it to the exterior, and wire it to a timer or humidity sensor. Combined with a waterproofed wet zone, that keeps the bathroom dry between showers.

Larger rooms with two people sharing them need more storage, lighting, and waterproofing decisions than a hall bath, and each of those shows up in the written estimate.

The cost depends on the size of the room, how much of the layout changes, whether plumbing or electrical work moves, the tile and fixtures you choose, and what we find behind the walls. That is why every job starts with a free written estimate after we see the room: you get the scope and the price in writing before any work begins, and we explain the cost in detail on the call. When you compare quotes, compare the scope line by line: one quote may price a finish as fixed while another holds it as an allowance that can change later.
A master bathroom remodel plans the layout, the shower, the tub, and the vanity together, with storage, lighting, and entry decided as one room. The work can include a new shower, a freestanding or built-in tub, a double vanity, new tile, and new fixtures, all agreed in the written scope before work starts.
Whether a permit is needed depends on the scope of the work and the city your home is in (in the City of Los Angeles, that is the Department of Building and Safety; other cities have their own building departments, and unincorporated areas go through Los Angeles County) Work that moves plumbing, electrical, or structure is the kind that usually needs one, while a like-for-like swap often does not. We confirm what your master bathroom remodeling job needs before work begins, so there are no surprises. If you own a condo, your homeowners association's approval is separate from a city permit, so bring your HOA's rules to the free written estimate.
How long a master bathroom remodel takes depends on the scope, the size of the room, and the selections you make. Your written estimate sets out the schedule before work begins, so you know the plan before demolition starts, and the scope you approve is the scope we build to.
It depends on the size of the room and the layout. Some primary suites fit both comfortably; in others, keeping both means giving up storage or floor space you need more. We measure the room, draw the options, and agree the layout with you in writing before work starts.
