A primary bathroom remodel in Los Angeles usually takes four to eight weeks of construction, with custom glass and specialty tile adding lead time. The most important part of a long-lasting bathroom is the waterproofing behind the tile, which should be flood-tested before any finish is installed. Moving plumbing, electrical or walls requires a permit.
The Bathroom Is Where Quality Shows Up Years Later
Most bathroom failures are invisible on the day a project is finished. A shower that leaks slowly through a poorly sealed corner can rot framing and grow mold for years before anyone notices a stain on the ceiling below. That is why we treat the hidden layers of a bathroom, including the substrate, the membrane, the slope to the drain and the ventilation, with the same seriousness as the finishes you choose.
Our tile setters install continuous waterproofing membranes over the shower walls and floor, form properly sloped shower pans and test them before tile goes on. The result is a bathroom that looks as good in fifteen years as it does the day you move back in.

Built for Southern California Conditions
Marine-layer humidity on the coast
Homes in Malibu, Santa Monica and Pacific Palisades live with the marine layer for weeks each spring and early summer. Morning fog keeps humidity high, and bathrooms that already produce moisture can struggle to dry out. We specify humidity-sensing exhaust fans that run automatically until the room is dry, mold-resistant backer boards and paints, and detailing that keeps moisture out of wall cavities.
Water efficiency
California sets strict flow limits for showerheads, faucets and toilets. Modern fixtures can perform beautifully within those limits, but quality varies widely between brands. We help you choose fixtures that deliver a satisfying shower while meeting state requirements.
Hard water
Much of the Los Angeles area has hard water, which leaves mineral spots on glass and can shorten the life of steam generators and some valves. We often recommend protective coatings on shower glass and, where appropriate, filtration for steam systems, so your bathroom is easier to keep looking new.
Before any tile is installed, a properly built shower pan should be plugged and filled with water for at least 24 hours to confirm there are no leaks. We perform this test on every shower we build and photograph the results for your records. If a contractor cannot tell you how they test waterproofing, keep looking.
Designing for Accessibility Without Looking Clinical
Many clients want a bathroom that will serve them comfortably for decades. Curbless shower entries, wider doorways, comfort-height toilets, well-placed lighting and concealed blocking in the walls for future grab bars can all be designed in from the start. When they are planned carefully, these features look like thoughtful luxury rather than medical equipment, and they make the room easier for everyone to use.
What Affects the Cost of a Bathroom Remodel
The biggest cost drivers are layout changes, such as moving a toilet or converting a tub to a curbless shower, which can require floor framing and drain work. Tile choice and complexity matter too: large-format slabs and intricate patterns take more labor than simpler installations. Custom glass, steam systems, heated floors and custom vanities each add to the budget. We give you a realistic range during your consultation and a fixed-price proposal once selections are made.

Frequently Asked Questions
How long does a bathroom remodel take?
Most primary bathroom remodels take four to eight weeks of construction. Custom shower glass is measured after tile is installed and can add two to three weeks of lead time.
Do I need a permit for a bathroom remodel in Los Angeles?
A permit is required when you move or add plumbing, electrical circuits, ventilation or walls. Most full bathroom remodels need one.
Can a tub be converted to a curbless shower?
Usually, yes. A curbless shower often requires recessing the floor framing or adjusting the drain location, which we evaluate during the site visit.
How do you prevent leaks and mold?
We install continuous waterproofing membranes, slope shower floors correctly, flood-test every pan for 24 hours, and specify humidity-sensing ventilation and mold-resistant materials.
Are heated floors worth it in Los Angeles?
Many clients love them, especially in coastal homes where mornings are cool and damp. Electric radiant mats are efficient for bathroom-sized areas and are easy to control with a programmable thermostat.
