Luxury Bathroom Remodel Contractors in Calabasas and Thousand Oaks (2026)

Luxury Bathroom Remodel Contractors in Calabasas and Thousand Oaks (2026)

Four cities, three permit desks, and a price band that starts where most of Los Angeles stops. Here is who actually builds high-end bathrooms in this corridor, what they cost, and the paperwork nobody mentions until week three.

Key takeaways

• Five contractors worth a call: Westside Remodeling, Preferred Home Builders, Forest Construction, Eagle Pride Construction, and Lotus Kitchen & Bath. They are not interchangeable. Each one is built for a different kind of job.
• Luxury here starts around $65,000 for a master bathroom with layout changes, and a full custom bathroom in Hidden Hills or Lake Sherwood clears $150,000 without anyone trying.
• You are dealing with three separate jurisdictions. Calabasas and Agoura Hills answer to their own city building departments, Thousand Oaks sits in Ventura County, and the unincorporated pockets between them go through LA County. Same corridor, different rules.
• A design-build system is worth more here than anywhere else in the region, because hillside lots and gated community design review add review cycles that a designer and a separate contractor tend to fumble between them.
• The single biggest cost driver is not tile. It is whether you move plumbing. Keeping the water closet and drain where they are can save you fifteen thousand dollars before you have picked a finish. Everyone in this business says the same three words: quality craftsmanship, premium materials, customer satisfaction. Useless. They tell you nothing about whether a company can actually pull a permit in Thousand Oaks or handle a soft-close pocket door without three site visits.

So this is a working list, not a popularity contest. No star ratings, no invented scores. Just what each of these firms is genuinely built to do, and where they are the wrong call.

The 5 luxury bathroom remodel contractors serving Calabasas and Thousand Oaks

Every firm below was checked against its own published material, a directory listing, and a license record. Where I could not confirm something, I left it out rather than guess.

• Westside Remodeling Thousand Oaks, CA Best for: homeowners who want to touch the tile before they commit to it. In business since 1985 and running a kitchen and bath showroom in Thousand Oaks that you can walk into and put your hands on. That sounds small. It is not. Choosing countertops and marble tile off a laptop screen is how people end up hating their own bathroom, and almost nobody in the Conejo Valley makes the in-person version this easy. They run a design-build system, so design and construction sit under one contract. Their published service area covers Agoura Hills, CA, Calabasas, CA, Oak Park, CA, Newbury Park, CA, Camarillo, CA, Moorpark, CA, Simi Valley, CA and Westlake Village. They have picked up a Professional Remodeler "Big 50" award and their work has been featured in design press. Where they are not the fit: a showroom-led firm carries showroom overhead. If your project is a straightforward small bathroom remodel, you may be paying for infrastructure you never use.
• Preferred Home Builders Canoga Park & Culver City, CA Best for: luxury bathroom work that involves structural change, permits, or more than one room. Full disclosure, this is our publication. Judge the claims accordingly, and go verify them. License #773147, founded 1996, licensed and insured, north of 3,000 completed projects. We run a full design-permit-build team in house, which is the part that matters when a master bathroom turns into an engineering conversation about a bearing wall. The Conejo Valley record is real and it is public. Completed master bathroom remodels in Calabasas, a combined master and powder room build, bathroom remodeling in Thousand Oaks, multiple bathrooms in Westlake Village, a tub to shower conversion in Agoura Hills, a modern master bath in Oak Park, and work in Simi Valley, Bell Canyon and Pacific Palisades. Two seasons of HGTV's Help! I Wrecked My House as well. Free estimates and a free in-home design session with 3D renderings, then a fixed-price proposal before demolition. Bathroom remodeling sits alongside kitchen remodeling, interior remodeling, room additions and home additions, garage conversions and accessory dwelling units under one home remodeling operation, so whole-home remodels do not get handed off halfway. Where we are not the fit: we are headquartered in the San Fernando Valley and on the Westside, not in the Conejo Valley. There is no local showroom to drop into on a Saturday. If proximity is your first filter, Westside Remodeling or Forest Construction sit closer to your kitchen table.
• Forest Construction Thousand Oaks, CA Best for: projects where the bathroom is one piece of a much larger construction job. Four decades plus in the Conejo Valley, license #398317, and by their own count more than 8,000 clients across Southern California. They keep kitchen and bath designers on staff rather than subcontracting design out, which shows up in how tightly the drawings match what gets built. They are a genuine general contractor in the old sense: custom homes, commercial buildings, additions, high-end kitchen and bath. If your custom bathroom is part of a bigger renovation, that depth is an asset. They have been recognized by Qualified Remodeler and voted a favorite contractor by Ventura County Star readers. Where they are not the fit: a firm running commercial construction and custom home builds alongside residential remodels is splitting attention. Ask directly who is running your job and how many others they are running that month.
• Eagle Pride Construction Ventura, CA (serving the Conejo Valley) Best for: accessible bathrooms and aging-in-place conversions done properly. Founded in 2005 by Gary Kuppenbender, a retired Navy Seabee, and veteran-owned since. They report more than 2,500 completed projects and work through design, permits and construction as one team. Coverage runs across Thousand Oaks, Westlake Village, Calabasas, CA, Moorpark, CA, Simi Valley, CA and Camarillo, CA. What stands out is the accessibility work. Curbless entries, grab-bar blocking set before the tile goes on, turning radius that actually works. Most contractors treat accessible bathrooms as a fixture order. This is one of the firms that treats it as a layout problem, which is what it is. Where they are not the fit: they are based in Ventura. Calabasas is the outer edge of that radius, and drive time quietly becomes your problem on a job with daily trade coordination.
• Lotus Kitchen & Bath Serving Thousand Oaks, Calabasas, Agoura Hills & Simi Valley Best for: fast, fixture-led upgrades and flooring, not structural remodels. A Bath Concepts dealer offering one-day bath upgrades, walk-in bathtubs and accessible conversions, plus flooring installations across hardwood, laminate and carpet. Roughly 25 years in the trade, licensed and insured, same-day consultation availability, and a warranty on the products they install. Be clear on what this model is. It is a product-led installation business, and it is very good at what it does. A tub to shower conversion in two days with a sealed, precision-cut surround is a real solution for a real customer. Where they are not the fit: the moment your scope of work includes moving a wall, relocating a water closet, or anything requiring a building permit and structural engineering, this is the wrong tool. Fast project turnaround and a full custom bathroom are different products. Do not let anyone sell you one as the other.

Others you may encounter

ORO Coast Builders is a licensed design-build firm out of West Hills with in-house engineering, and it publishes a Calabasas landing page. Its stated service map centers on the Westside rather than the Conejo Valley, so treat the local claim carefully. Names like A1 Kitchen & Bath Remodeling and Precision Custom Bathrooms surface in directory results for this area, but I could not confirm an active Conejo Valley footprint for either, so they are not ranked here. Run any name through the CSLB license lookup yourself before you sign anything. It takes ninety seconds.

Who should you hire for a luxury bathroom remodel in Calabasas or Thousand Oaks?

Short answer: hire a full service design-build contractor if your project touches plumbing locations, walls, or windows. Hire a specialty installer if it does not.

That is the whole decision. Everything else is preference.

Here is why it matters more in this corridor than it does in, say, Sherman Oaks. Homes in Calabasas, Hidden Hills, CA and Lake Sherwood, CA tend to sit on hillside or semi-rural lots with grading and drainage conditions attached to the original permit. Move a drain line in a house like that and you can trip a review nobody scoped. When design and construction are contracted separately, that discovery turns into a finger-pointing exercise, and the change orders start stacking.

Under a design-build system, one team owns the drawings, the permit application, the engineering and the build. There is nobody to blame but them, which is exactly the accountability you are paying for.

A quick word on terminology, because these get used interchangeably and they should not be. Bathroom repair is fixing what broke: a failed pan, a leak, rot behind a wall. Bathroom installation is swapping fixtures into an existing footprint. A shower remodel replaces the enclosure and waterproofing without touching the rest of the room. Bathroom reconstruction is a full rebuild, usually after water or fire damage, and it runs on a different scope and a different insurance track. Only the last two reliably need a permit. Ask a contractor which one they think they are quoting, and make sure it matches what you think you are buying.

What a luxury bathroom actually costs here in 2026

Start with the regional baseline. Our own Los Angeles bathroom remodel cost guide puts a mid-range renovation on an existing layout at $25,000 to $45,000, and a primary bathroom with layout changes at $45,000 to $85,000. Labor eats 40% to 60% of the budget.

The Conejo Valley runs above that. Not because the tile is different. Because of access, lot conditions, longer lead times on specification-grade product, and design review in the gated communities.

| Scope | Typical cost | Construction time | Permit likely? ||---|---|---|---|| Powder room refresh | $12,000 to $25,000 | 2 to 3 weeks | Usually no || Small bathroom remodel, same layout | $22,000 to $38,000 | 3 to 4 weeks | Sometimes || Guest or hall bath, standard renovation | $28,000 to $48,000 | 3 to 5 weeks | Yes, plumbing and electrical || Master bathroom, mid-range renovation | $40,000 to $65,000 | 4 to 6 weeks | Yes || Master bathroom, upscale renovation with layout changes | $65,000 to $120,000 | 6 to 10 weeks | Yes, plus engineering || Full custom bathroom, Hidden Hills or Lake Sherwood tier | $150,000 and up | 10 to 16 weeks | Yes, plus design review || Tub to shower conversion, no relocation | $12,000 to $28,000 | 1 to 3 weeks | Usually yes |

Derived from published Los Angeles ranges plus a 15% to 25% Conejo Valley premium. Confirm your own numbers at estimate.

Budget a 10% to 15% contingency. In pre-1980 housing stock across Agoura Hills and older Thousand Oaks tracts, that is not padding. That is the galvanized supply line you have not found yet.

The one number that moves everything: relocating the toilet drain. Everything else, marble tile versus porcelain, quartz countertops versus stone, is a rounding error next to it. Keep the water closet where it is and you have already controlled your budget more than any material substitution will.

Three cities, three permit desks, one very confused homeowner

This is the part that catches people, and I have never seen it explained properly on a contractor website. The Calabasas to Thousand Oaks corridor looks like one continuous suburb. It is not one jurisdiction.

Calabasas and Agoura Hills, CA

Both are incorporated Los Angeles County cities with their own building departments and their own review timelines. Calabasas in particular applies design standards that can reach further than you expect, and several neighborhoods add an HOA architectural review on top of the city process. Agoura Hills runs its own building and safety inspections and schedules them directly.

Thousand Oaks, Westlake Village and Newbury Park, CA

Thousand Oaks is Ventura County, not Los Angeles County. Different building department, different fee schedule, different inspector culture. The City of Thousand Oaks Building Division handles residential permits directly. Westlake Village straddles the county line in a way that confuses even locals, so confirm your parcel before anyone submits.

The unincorporated pockets

Santa Rosa Valley, parts of the Santa Monica Mountains, and various canyon parcels are unincorporated. Those go through LA County Building and Safety or the Ventura County equivalent depending on which side of the line you sit. Add weeks, not days.

Statewide, every permitted bathroom is also subject to California Title 24 energy standards, which govern lighting efficacy and mechanical ventilation. Recessed lighting has to hit efficacy requirements, and your exhaust fan needs to move real air and be controlled correctly. Inspectors here check it.

Fixture flow rates get checked too. California limits showerhead flow more aggressively than the federal standard, which matters if you were planning multiple shower heads. The EPA WaterSense program is the useful reference for what qualifies.

Premium materials that survive a decade, and the ones that just photograph well

The luxury market in this corridor has settled into a fairly consistent specification. Some of it earns its money. Good material curation is knowing which half.

• Custom cabinetry and double sink vanities. Semi-custom lines like Dura Supreme cabinets show up constantly in this price band and hold up well. Full custom is worth it only when the room has an odd dimension that stock cannot solve.
• Countertops. Quartz for anything that gets daily abuse. Marble if you accept etching as patina and genuinely do not mind. People say they do not mind. Half of them mind.
• Marble tile and large format porcelain. Large format cuts grout lines and reads more expensive, but it demands a much flatter substrate. That prep is labor, and labor is the budget.
• Walk-in showers and custom showers. Curbless entry is the single best luxury upgrade available, and it doubles as accessibility. It requires the shower pan to be set into the framing, so it has to be decided at design, not later.
• Brizo plumbing fixtures and similar specification lines. Real quality difference in cartridge and finish durability. Digital displays for fixtures and thermostatic valves are genuinely nice and genuinely a service consideration in ten years.
• Freestanding solid-surface tub versus deep whirlpool tubs. Freestanding wins on looks and loses on ergonomics. Whirlpool tubs need access panels and a motor that will eventually need service. Plan the access now.
• Soft-close pocket door. Small detail, disproportionate effect in a tight master bathroom. Needs wall depth resolved during framing.
• Custom motorized window treatment. Requires power in the header. Decide before drywall or you are cutting into finished work. Layout beats every one of these. We wrote a whole piece on the primary bath layout mistakes we fix most often, and it is mostly door swings, wet zone planning and natural lighting. Get those right and a modest material budget looks expensive. Get them wrong and no amount of premium materials rescues the room.

Comparing the contractor types

| Model | Handles permits | Structural work | Typical timeline | Best use ||---|---|---|---|---|| Full service design-build contractor | Yes, in house | Yes, with engineering | 6 to 16 weeks | Layout changes, whole-home remodels || Design firm plus separate general contractor | Split responsibility | Yes | 10 to 20 weeks | Highly bespoke design, patient owner || Showroom-led remodeler | Yes | Yes | 6 to 14 weeks | Material-driven decisions, in-person selection || Product dealer or one-day bath installer | Limited | No | 1 to 5 days | Tub remodeling, surrounds, accessible upgrades |

How the four business models in this market actually differ.

How to vet a contractor before you sign

Six questions. They separate the serious firms from the ones with a good photographer.

• Show me the license and the insurance certificate. Not a screenshot. The CSLB record, live, plus general liability and workers' compensation naming you as certificate holder. Licensed and insured is a claim until it is a document.
• Who pulls the building permit? If the answer is "you can, it's cheaper," walk. An owner-pulled permit transfers liability to you. That is the entire reason they suggested it.
• Give me the scope of work in writing. Line item, labor and materials separated, allowances stated as real numbers. A written contract that says "bathroom remodel, $70,000" is not a contract. It is a hostage situation.
• How do change orders work? Ask for the process and the markup percentage before you need it. Our guide to reading a fixed-price proposal covers what the language should look like.
• What is the workmanship warranty, in years and in writing? Separate from manufacturer warranties on fixtures. Get both.
• Can I see a job site running right now? The best predictor of your experience. Organized job sites, dust containment, protected flooring, tools put away. Transparent communication is easy to promise on a sales call and hard to fake on a Tuesday afternoon in someone's hallway. Get at least three bids with the same scope. Competitive pricing only means something when everyone is quoting the same job. A low number usually means a smaller scope, not a better deal.

A note on the fire rebuild markets. Homeowners in Pacific Palisades, CA and Altadena, CA are navigating a very different process, where bathroom work sits inside a full reconstruction and insurance scope. Different timeline, different documentation, different contractor requirements. Do not use a standard remodel bid as your benchmark there.

The bottom line

Pick the model before you pick the company. If your project involves permits, engineering or a changed layout, you want a full service design-build contractor and you should be talking to Westside Remodeling, Preferred Home Builders or Forest Construction. If it is a surround, a tub remodeling job or an accessibility upgrade, a specialist will do it faster and cheaper and you should not be paying design-build overhead for it.

Then verify the license, demand the scope of work in writing, and go stand in a job site. The rest is tile.
