A bathroom is one of the most used rooms in a home and one of the priciest to get wrong. Water, tile, and hidden plumbing leave little margin for a sloppy job, so the contractor you pick matters as much as the design. Los Angeles and its surrounding valleys hold hundreds of licensed remodelers, including single-trade bath specialists and full-service design-build firms, so the hard part is not finding one. It is narrowing the field to a company that fits your project, your budget, and the way you want the work run. 

The five below are established Los Angeles bathroom remodelers with verified licensing and real project histories. Costs and timelines here are general references that vary by project.

What to Check Before You Hire a Bathroom Remodeler

Before comparing names, know what separates a safe hire from a risky one. A bathroom remodel touches plumbing, electrical, waterproofing, and often the layout, so the fundamentals matter more than the sales pitch.

  • License and insurance: Confirm an active CSLB license, plus current bonding and insurance. Any license number can be checked on the state board’s site.
  • Permits and code: Work that moves plumbing, changes electrical, or alters the layout needs a permit and inspection through the local building department. Ask how the company handles it.
  • How the work is structured: Some firms keep design, permits, and construction in-house, while others subcontract parts out. Know which you are getting.
  • Communication and schedule: Older homes hide surprises behind the tile, so ask how the company handles delays and change orders once demolition starts.
  • Track record: Look at review volume, dated project photos, and years in business, not just a star rating.
  • Contract terms: A written scope, line-item pricing, and a workmanship warranty protect you if something goes wrong.

Five Bathroom Remodeling Companies to Consider

Five bathroom renovation companies working across Los Angeles, each measured on the same points: years operating, how they run projects, and who they tend to suit.

Supreme Remodeling Inc

Supreme Remodeling Inc  has served Los Angeles since 1995, giving it more than 30 years in the local market, and operates out of Van Nuys under CSLB license #939981, which any homeowner can verify on the state contractors board site. It is a full-service general contractor handling kitchens, bathrooms, room additions, and ADUs, with hillside and complex-site construction among its stated focus areas. The company runs its own crews rather than leaning on subcontractors, which usually gives a homeowner one point of accountability and steadier day-to-day scheduling once work starts. Because the firm covers the full range of residential work, a bathroom can be planned as one part of a wider renovation without bringing in a second contractor. For a single, self-contained bathroom, a large generalist may have more capacity than you need, so ask how a smaller job fits their schedule. 

Top of Mind Home Remodeling

Top of Mind Home Remodeling is a family-owned company based in Valley Village, operating under CSLB license #1122867 with more than 20 years of experience in the Los Angeles market. Its core is bathroom and kitchen remodeling, and its process keeps design, LA City permitting, and construction under one roof, with clear scheduling and consistent communication through the build. A smaller, owner-involved team often means the person who quotes your job is close to the person running it, which can make questions easier to resolve mid-project. Being local, family-owned contractors, they are well versed in LA permits and inspection requirements, which gives peace of mind while trusting them with your bathroom. For a homeowner who wants a defined bath or kitchen project handled directly rather than absorbed into a large pipeline, that personal level of detail is the appeal. 

Preferred Home Builders

Preferred Home Builders is a design-build firm in Canoga Park that has operated since 1996. It reports more than 3,000 completed projects and has had work featured on HGTV, which is among the longer records of any remodeler in the local market. Design-build means one company is accountable for the design, the permits, and the construction, so a homeowner is not left coordinating between a separate designer and builder. In practice that can shorten planning and cut the finger-pointing that happens when a drawing does not match what a crew can actually build. The trade-off is that you commit to one firm’s design team rather than shopping a plan around, so it helps to like their past work before you start. The model suits homeowners who want a single team to carry a bathroom or a full remodel through every stage. A longer track record also gives you more finished projects to check before you sign.

One Week Bath

One Week Bath is a bathroom specialist that has operated in the Los Angeles area since 2000. Unlike the general contractors on this list, it works on bathrooms alone and advertises a compressed build schedule, with a commitment to finish the on-site portion quickly once a project starts. It uses its own crews instead of subcontractors, so the same team is in the home each day, and the single-trade focus means the people doing the work handle bathrooms repeatedly rather than occasionally. That kind of repetition tends to show in the waterproofing and tile detailing where bathroom problems usually begin. The model can suit a homeowner who wants one bathroom done with minimal disruption and a predictable timeline. The short on-site window usually depends on decisions and materials being locked in beforehand, so planning still takes real time even when construction is fast. If your plans reach beyond the bathroom, a bath-only company will not cover the rest, so a wider renovation needs a general contractor.

Pearl Remodeling

Pearl Remodeling is a full-service design-build company based in Reseda, with a large review base and an in-house interior designer on staff. Keeping design and construction under one roof means material selection, layout, and the build can move together rather than being split between separate professionals. For a bathroom, that can help with the parts people underestimate, such as tile layout, lighting placement, and how fixtures sit in a tight footprint. The company also works on kitchens, additions, and whole-home renovations, so a bathroom can be folded into a larger project when needed. Design help built into the service suits homeowners who know roughly what they want but would rather not manage every aesthetic decision alone. If you already have your own designer or a fixed plan, some of that in-house work may duplicate what you have, so clarify what is included in the price before you commit.

How to choose between them

Once you have two or three finalists, a few steps separate the right fit from the rest of the remodeling companies you looked at.

  • Get at least three fixed-price bids on an identical scope. A lower number that quietly includes cheaper fixtures is not really a lower price.
  • Verify each license yourself on the state contractors’ board rather than taking a number on faith.
  • Ask for references from projects finished in the last year, and look at photos of real jobs instead of stock images.
  • Read the contract before you sign. Check that the scope, the payment schedule, and the warranty are all written down.

Frequently asked questions

How much does a bathroom remodel cost in Los Angeles? 

It varies widely. A modest update with mid-range materials is commonly estimated in the low-to-mid five figures, while a full bath remodel with layout changes and high-end finishes runs higher. The final cost depends on room size, materials, and what the crew finds once demolition begins. Treat any figure before an in-home estimate as a rough guide.

How long does a bathroom renovation take? 

Most standard bathroom projects are commonly reported to need a few weeks of on-site work, though permitting and material lead times can stretch the overall schedule. Ask each company for a timeline in writing.

Do I need a permit to remodel a bathroom in LA? 

Usually yes, if the work involves plumbing, electrical, or layout changes. Purely cosmetic updates, such as paint or swapping a vanity in place, often do not. The Los Angeles Department of Building and Safety is the authority on what your project requires, and a licensed contractor should handle the permit process.

Choosing the Right Fit

The best pick is rarely the biggest name or the lowest bid. It is the bathroom remodeling company whose scope, schedule, and way of communicating line up with the project you actually have. A large generalist makes sense for a bathroom tied into a wider renovation, while a specialist or a smaller family-run team can be the better call for a single, self-contained bath. 

Whichever way you lean, treat this shortlist as a starting point rather than a verdict. Meet two or three companies, compare fixed-price bids on the same scope, verify each license yourself, and read every contract before you sign. The team that answers your questions clearly before the job is usually the one that handles the surprises well once the walls are open.
