Figures below are planning ranges for Greater Los Angeles, intended to help you build a realistic budget. They are not a quote — every project is priced from its own site, scope, and selections.
What a bathroom remodel includes
A full bathroom remodel takes the room back to the framing and rebuilds it: plumbing, waterproofing, tile, vanity, fixtures, lighting, and ventilation. That is the only way to see and fix what decades of water have done behind the walls.
We build both primary suites and smaller guest baths. The scope differs, but the order of work does not, and neither does the care that goes into the parts you will never see.
What a bathroom remodel costs in Los Angeles
A permitted primary bathroom remodel in Greater Los Angeles typically costs $40,000 to $90,000. A secondary or guest bath typically costs $25,000 to $50,000. Tile complexity and fixture selection drive most of the difference.
Plan a 15 to 20 percent contingency. Opening a bathroom wall in an older house often reveals galvanized supply lines, cast iron drains near the end of their life, or rot under the old shower pan.
Waterproofing is the part that matters most
The finish you see is only as good as the waterproofing behind it. A shower is a system: a properly sloped pan, a continuous waterproof membrane, correct transitions at the curb, niche, and bench, and a drain that matches the floor.
This is where shortcuts hide, because nobody sees it once the tile is up. We build it carefully and in the right sequence, and we would rather spend an extra day here than come back in five years for a leak.
Choices that shape the room
A few decisions set both the look and the budget of a bathroom.
- Layout: moving a toilet or drain is far more expensive than keeping it
- Shower: a curbless walk-in shower needs a recessed floor and careful slope
- Tile: large-format and natural stone take more labor and more precise substrate work
- Fixtures: wall-mounted faucets and thermostatic valves have to be chosen before the walls close
- Ventilation and light: a properly sized, ducted fan protects every surface in the room
How we run a bathroom remodel
Every project follows the same four steps.
- Consult: we look at the room, talk through how you use it, and write down what is in this job
- Plan: drawings, a schedule, and a clear price before anyone starts, with fixtures selected up front
- Build: one crew, weekly updates and photos, and every change gets a written yes first
- Deliver: a walkthrough, a punch list, and we stand behind the work
Frequently asked questions
How much does a bathroom remodel cost in Los Angeles?
A permitted primary bathroom remodel in Greater Los Angeles typically costs $40,000 to $90,000, and a secondary or guest bath $25,000 to $50,000. Tile complexity, fixture selection, and whether the toilet or drains move account for most of the difference. These are planning ranges, not a quote.
Do I need a permit for a bathroom remodel?
Usually, yes. Plumbing, electrical, ventilation, and structural changes require permits in Los Angeles jurisdictions. We pull the permits and schedule the inspections with the building department that covers your property.
Can you build a curbless walk-in shower?
Often, yes. A curbless shower needs the floor recessed or built up so water slopes to the drain without a curb, which depends on the framing below. We check that during the site visit and tell you what it takes before design is final.
Why does waterproofing matter so much?
Because a bathroom is the most water-exposed room in a house, and failures happen behind the tile where nobody sees them until damage is done. A properly sloped pan, a continuous membrane, and careful transitions at curbs, niches, and benches are what keep a shower dry for decades.
