Bathroom Remodeling Contractors Working Across Los Angeles Neighborhoods
Aggregate Construction Group is a licensed bathroom remodeling contractor working across the Westside, the San Fernando Valley, and Central Los Angeles. Our crews run bathroom projects in Beverly Hills, Santa Monica, Brentwood, Westwood, Pacific Palisades, Encino, Tarzana, North Hollywood, and Valley Village. Most owners start with one bathroom and expand the scope once they see how the first room comes together, which is why we quote the work in a way that leaves room for that decision instead of locking it out.
The neighborhood changes the job more than most homeowners expect. Older properties on the Westside frequently hide cast iron drain lines and lath and plaster walls behind the tile, and that adds demolition hours nobody sees in a walkthrough estimate. Many post-war homes in the Valley sit on slab foundations, so moving a shower drain means cutting concrete instead of working from a crawlspace. Hillside lots bring access and staging limits that shape the schedule before a single fixture gets ordered. We scope around what is actually behind the wall, the same way we approach every job as general contractors in Beverly Hills and across the rest of the county.
The Bathrooms We Remodel in Los Angeles Homes
We remodel primary bathrooms, guest bathrooms, hall bathrooms, and powder rooms, along with bathrooms inside condominiums, duplexes, and accessory dwelling units. Small bathrooms under forty square feet make up a large share of the work in older Los Angeles housing, and they force decisions a large primary suite never needs, including pocket doors, wall-hung vanities, and curbless entries that hand back usable floor area. When the bathroom is part of a bigger build we fold it into the same schedule as the rest of the structure, which is how we run ADU construction in Los Angeles so the plumbing rough-in and the finish schedule never fight each other. We also build accessible bathrooms with blocking set for future grab bars, curbless showers, lever hardware, and comfort-height fixtures, which matters for owners who plan to stay in the house.
Waterproofing Assemblies and Finish Materials We Specify
Most failed bathroom remodels start at the waterproofing, not the tile. We install hot mop pans, sheet membranes, and liquid-applied membranes depending on the substrate and the shower design, always over cement backer board rather than green board. Slope is built into the pan before any tile is set, and the assembly gets water tested first. On the finish side we install porcelain, ceramic, and natural stone, large-format panels, custom niches and benches, linear and point drains, frameless glass enclosures, floating vanities, and integrated lighting. Tile that runs past the bathroom door is set by the same crew behind our floor installation, so the transitions line up instead of meeting at a threshold strip. Vanities, medicine cabinets, and built-in storage we fabricate ourselves get sized to the room rather than pulled from a catalog.
Permits, Inspections, and California Code on an LA Bathroom Remodel
Cosmetic like-for-like work in Los Angeles generally does not require a permit. The moment a project moves plumbing, adds circuits, changes ventilation, or takes out a wall, LADBS requires one. Non-structural bathroom remodels can often be pulled as an express permit with no plan check, while wall and opening changes go to plan review. Current projects are built to the 2025 California Building Standards Code, Title 24, effective January 1, 2026, which includes the California Plumbing Code in Part 5 and the CALGreen fixture flow limits in Part 11. Bathroom receptacles require GFCI protection. In homes built before 1994, California requires noncompliant plumbing fixtures to be swapped for water-conserving models, and shower and tub enclosures to use tempered safety glazing. We pull the permits, meet the inspector at rough-in and again at final, and close the permit out so the work is on record when the property sells. The whole process is broken down in our guide to Los Angeles bathroom remodel permits.
Property Types and Buildings We Work In
We work on single-family homes, condominiums, duplexes, small multifamily buildings, and rental units. Condominium projects run through HOA approval before demolition, and we prepare the scope documents, insurance certificates, and work-hour schedules most Los Angeles associations ask for. Bathroom work in occupied apartment buildings is sequenced unit by unit so tenants keep a working bathroom throughout, the same approach behind our apartment renovation and exterior work. Homes built before 1978 can also require lead-safe practices during demolition, which we plan for at the scoping stage instead of discovering mid-project.
Working With a Licensed Bathroom Remodeling Contractor in Los Angeles
Aggregate Construction Group holds California contractor license number 1034714 and carries general liability and workers compensation coverage. Every project starts with a written scope and a schedule, and any change is documented as a change order before the work happens rather than after. Owners remodeling more than one room often pair the bathroom with a kitchen remodel at the same time, since running both together shares the demolition, the permit, and the plumbing rough-in. Request a walkthrough and we will confirm scope, timeline, and next steps within one business day.
