AfterHow Much Does a Bathroom Remodel Cost in Thousand Oaks?
A full bathroom remodel in Thousand Oaks typically runs between $9,000 and $28,000 in 2026, with most mid-range projects landing around $15,000 to $19,000. Smaller guest baths and powder rooms come in lower, while primary suites with structural changes and premium fixtures push toward the top of that range. The spread is wide because two bathrooms on the same street can be completely different projects once you open the walls.
At Mason Remodeling, we put a written price in front of you before any work starts, so you know exactly where your project falls before you commit to anything. If you want a specific number for your bathroom, call (805) 309-3386 and we’ll walk you through it.
Bathroom Remodel Cost Breakdown (2026)
Here’s how bathroom remodel costs in Thousand Oaks break down by project scope. These numbers reflect what we’re seeing across Conejo Valley homes in 2026, from Lynn Ranch ranches to tract homes near the 101.
| Project Type | Typical Cost Range | What’s Included |
|---|---|---|
| Powder Room / Half Bath | $5,000 – $9,000 | Vanity, toilet, mirror, lighting, paint, flooring |
| Small Bathroom Remodel | $5,000 – $12,000 | 5’x8′ full bath, stock fixtures, basic tile |
| Full Bathroom Remodel | $9,000 – $28,000 | Standard 5’x8′ to 10’x10′ bath, mid-range fixtures, tile work |
| Walk-In Shower Installation | $4,500 – $12,000 | Shower pan, tile surround, glass enclosure, valve |
| Tub-to-Shower Conversion | $3,500 – $10,000 | Remove existing tub, install shower base and tile, glass door |
| Shower Replacement | $3,000 – $8,500 | Swap out existing shower unit, new valve and surround |
| Bathroom Vanity Installation | $800 – $3,000 | Vanity cabinet, countertop, faucet, drain work |
| Primary Suite Remodel | $20,000 – $45,000+ | Larger footprint, custom features, structural changes, heated floors |
What pushes a bathroom from $9,000 to $28,000? Three things, mostly. Plumbing relocation is the biggest one: moving a toilet or shower drain across the room means cutting into the slab or reworking the joists, and that’s real labor. The second is tile coverage: a floor-only tile job is a fraction of floor-to-ceiling tile with a niche, a bench, and a custom curb. Third is fixtures and finishes: a $200 Moen faucet and a $900 Grohe thermostatic valve are both fine choices, but they don’t cost the same to buy or install.
What the Numbers Include
When we write a price for a Thousand Oaks bathroom remodel, it includes permits, demolition, haul-away, plumbing and electrical work behind the walls, waterproofing (Schluter systems or equivalent), tile labor and materials, fixture installation, and finish work. What it doesn’t include, unless we specify it up front, are structural repairs found after demo, asbestos abatement in pre-1980 homes, or custom cabinetry beyond what’s in the scope.
Some Thousand Oaks neighborhoods have HOA review processes for anything visible from the outside. If your bathroom remodel involves moving a window or adding an exhaust vent that changes the exterior, plan for HOA paperwork time. It’s usually straightforward, but it can add a week or two before permits clear.
What Affects Bathroom Remodel Pricing in Thousand Oaks
Here’s what actually moves the number on a Thousand Oaks bathroom quote:
- Plumbing location changes: Keeping the toilet, sink, and shower where they are keeps costs down. Moving any of them means opening the subfloor, re-routing drains, and sometimes cutting concrete slab, which is common in post-1960 Conejo Valley construction.
- Home age and construction type: Thousand Oaks has a lot of 1960s and 1970s tract housing. Those bathrooms often have cast-iron drain lines, galvanized supply pipes, and drywall that doesn’t meet current code for wet areas. We budget for the possibility that we’ll need to replace old plumbing once the wall is open.
- Tile scope and material: Basic ceramic subway tile runs a few dollars per square foot. Large-format porcelain, natural stone, or handmade zellige tile from brands like Silestone or Caesarstone partners costs more, and installation labor goes up with tile size and pattern complexity.
- Shower waterproofing method: We use Schluter membrane systems (that’s the orange waterproofing fabric and metal trim that seals the edge where tile meets drywall) on every shower. It’s a specific product, not a generic one, and it costs more than old-school cement board. It also keeps water out of your walls for decades, which matters in a coastal climate like this one.
- Fixture grade: A basic Kohler or Moen shower valve and trim package starts around $200 to $400. A Grohe thermostatic system with multiple body sprays can run $2,000 to $4,000 before labor. Both go in the same wall; the difference is entirely in the hardware.
- Ventilation and code upgrades: Current California code requires a bathroom exhaust fan that vents to the exterior, not into the attic. If your existing fan doesn’t meet that, adding a properly vented unit and running ductwork is part of the remodel cost.
Walk-In Shower vs. Tub in Thousand Oaks
A lot of Thousand Oaks homeowners ask us whether they should keep the tub or convert to a walk-in shower. The honest answer depends on your family and your resale timeline. If you’re planning to sell within a few years, keeping at least one tub in the house matters because families with young children expect one. If you’re staying put and nobody uses the tub, a walk-in shower opens up the room and is easier to age into.
A tub-to-shower conversion in Thousand Oaks runs $3,500 to $10,000. That includes removing the old tub, building the shower pan, waterproofing, tiling the surround, and installing a glass door or panel. You’ll spend more if you go with a curbless entry, which some homeowners in Newbury Park and Westlake-adjacent neighborhoods prefer for accessibility, because it typically requires lowering the subfloor or building up the bathroom floor.
Permits and Code Requirements in Thousand Oaks
Any bathroom remodel that touches plumbing, electrical, or structural framing requires a permit in the City of Thousand Oaks. If you’re swapping fixtures in place without moving plumbing, you might not need one. If you’re moving a shower drain, adding a dedicated circuit for heated floors, or changing the footprint, you do. We pull these permits as part of the project, and the cost is included in our written price, not added on later.
California’s Title 24 energy code also applies to bathroom remodels when you’re changing more than 50% of the room. That usually means the new exhaust fan needs to be a high-efficiency model, and any new lighting must be LED or meet the wattage limits. These are standard parts of how we scope a bathroom project, and they’re included in the quote.

How to Save on a Bathroom Remodel
You don’t have to spend $28,000 to get a bathroom you’re happy with. Here’s how Thousand Oaks homeowners keep a remodel in the $9,000 to $15,000 range without cutting corners on the things that matter.
- Keep the layout: Leaving the toilet, sink, and shower exactly where they are saves thousands in plumbing labor and slab work. This is the single most effective cost control on any bathroom project.
- Choose tile strategically: Use premium tile on the shower walls where you see it, and a simpler porcelain on the floor or behind the vanity. You’ll save hundreds without changing how the room feels.
- Budget the vanity separate from custom cabinetry: A quality stock or semi-custom vanity from KraftMaid or Wellborn costs far less than fully custom millwork, and it installs faster. That’s real money back in your pocket.
- Do one room at a time: If you have two or three bathrooms that need work, staging them over 12 to 18 months lets you spread the cost without paying for a larger crew on a single timeline.
- Avoid change orders mid-project: The most expensive words in remodeling are “while you’re in there.” We scope everything up front and give you a written price before demo starts, so you can decide what you want before the walls are open.

FAQs – Bathroom Remodel Cost
How much does a bathroom remodel cost in Thousand Oaks in 2026?
A full bathroom remodel in Thousand Oaks typically costs $9,000 to $28,000, depending on size, fixture grades, and whether you move plumbing. Small bathrooms and powder rooms can run as low as $5,000 to $9,000. For an exact price on your project, call (805) 309-3386 for a free estimate.
Is it cheaper to remodel a small bathroom or a full bathroom?
Small bathrooms cost less in absolute terms, a Thousand Oaks small bathroom remodel runs $5,000 to $12,000, but the cost per square foot is often higher because the fixed costs (permit fees, plumbing, electrical) get spread over a smaller area. A 5’x8′ bathroom and a 10’x10′ bathroom both need a plumbing rough-in, a fan, and a permit. The bigger room just spreads those costs over more space.
What’s the most expensive part of a bathroom remodel?
Plumbing relocation is usually the most expensive single item, often adding $2,000 to $7,000 to a Thousand Oaks project depending on whether we’re cutting slab or working in a crawlspace. Next is tile labor for full surrounds, followed by custom shower glass. Keeping the existing layout is the biggest cost saver available.
How long does a bathroom remodel take in Thousand Oaks?
A standard full bathroom remodel takes 3 to 5 weeks from demo to final walkthrough. Permits add 1 to 3 weeks before work starts, and HOA review can add another week or two if your project is visible from the exterior. We’ll give you a timeline in your written price so you know what to expect.
