Trusted Bathroom Remodeling for Thousand Oaks Homeowners
Bathroom Remodeling in Thousand Oaks typically costs between $9,000 and $28,000, and the work usually takes two to four weeks depending on scope. If you’re standing in a bathroom with cracked tile, a tub that’s impossible to climb into safely, or cabinetry that’s warped from years of humidity, you’re not alone. We see these exact conditions in homes across Newbury Park, Lynn Ranch, and Wildwood every week. Isaac Pruett and the crew at Mason Remodeling Co Thousand Oaks have handled bathroom renovations in the Conejo Valley since 2004. Every project gets a written price before we start, and every crew member who walks through your door arrives in uniform with a photo ID badge and their name and photo sent to you in advance. Call (805) 309-3386 to talk through your bathroom.
Bathroom Remodeling Contractor

A Bathroom Remodeling Contractor is the licensed professional who manages the demolition, plumbing, waterproofing, electrical, tiling, and fixture installation that goes into a full bathroom renovation. You need one when the job involves moving drain lines, altering a shower footprint, or anything beyond swapping a faucet. Mason Remodeling Co Thousand Oaks has acted as the bathroom remodeling contractor for Thousand Oaks homeowners since 2004, carrying every project from initial measurement through final inspection. Our bathroom remodels run from $9,000 for a modest full refresh to $28,000 for a complete gut and reconfiguration with premium finishes.
What We Manage On Site
We handle every trade directly. Plumbing changes, electrical relocation, shower pan construction, tile setting, glass installation, and finish carpentry all sit under our roof rather than being subcontracted out to names you’ve never met.
This matters because most bathroom problems trace back to coordination failures between trades. One crew, one written price, one point of contact.
Permits And Inspections
Thousand Oaks plumbing and electrical permits are pulled on every project where code requires them. We handle the paperwork, schedule the inspections, and pass them before you sign off.
If a contractor tells you permits are optional, walk away. The city will catch up with unpermitted work eventually, and your title insurance will ask questions.
Styles & brands we work with







Walk In Shower
A Walk In Shower replaces a tub or an enclosed shower stall with an open, curbless or low-curb entry that you step into without lifting your legs over a barrier. It’s the most requested feature in our Thousand Oaks bathroom remodels, especially from homeowners planning to stay in their homes as they age. Mason Remodeling Co Thousand Oaks builds walk in showers with properly sloped mortar beds, reinforced wall blocking for grab bar installation, and waterproofing that extends to the ceiling in wet zones. Walk-in shower installation ranges from $4,500 for a straight replacement to $12,000 for a custom tile surround with a frameless glass panel.
Curbless Entry Details
A true curbless walk in shower requires dropping the shower floor into the joist bay or raising the bathroom floor slightly. We won’t fake it by lowering the curb an inch and calling it accessible.
In Thousand Oaks homes with post-tension slabs, which are common in developments from the 1970s onward, we verify slab conditions before planning any recessed shower floor. That step prevents a very expensive surprise.
Glass And Hardware Choices
We frame, measure, and install your walk in shower for either framed, semi-frameless, or frameless glass systems. Hardware finishes are matched to your existing faucet trim or switched entirely if you’re updating everything.
Every tile edge where glass meets wall gets a Schluter strip – the metal trim that seals the edge where tile meets flooring or drywall – so you don’t get a raw, chipped tile line.
Bathroom Remodeling Companies

Bathroom Remodeling Companies range from one-man operations working out of a truck to full design-build firms, and the difference shows up in pricing, timeline, and what happens when something goes wrong six months later. You need to compare companies carefully when your project involves waterproofing, gas line work, or structural changes, because the cheapest quote rarely survives contact with the first unexpected condition. Mason Remodeling Co Thousand Oaks operates as part of the Threshold Group family of home-service companies, founded in 2004, and holds to Threshold Verified standards on every job: written price before work begins, identity-verified crew members, and a 365-Day Done Right Promise in writing. Our Thousand Oaks bathroom remodels run $9,000 to $28,000.
How To Vet Any Company
Ask for the name and photo of who is arriving before you sign anything. Ask what the written price includes. Ask what happens when tile cracks at month ten.
Then watch how they answer. A professional answers directly. Someone hiding behind “we’ll take care of you” without specifics won’t be around when the follow-up falls apart.
What Sets A Threshold Group Company Apart
The Threshold Standard means something specific: background-checked, identity-verified technicians in clean marked uniforms who show a photo ID badge at the door. You know who is coming before they arrive.
That’s not a marketing line. It’s the operating standard we’ve held since day one, and we publish the details in our written guarantee on every project.
Bathroom Renovation
Bathroom Renovation is the broader term for updating and restoring an existing bathroom rather than building new square footage, and it’s the sweet spot for most Thousand Oaks homeowners whose homes were built in the 1960s through the 1990s. You need it when your bathroom functions but doesn’t work: dated pink tile, a tub that leaks into the ceiling below, a vanity that’s delaminating from moisture at the base. Mason Remodeling Co Thousand Oaks renovates bathrooms in Oak Park, Newbury Park, and across the Conejo Valley, and our renovation projects span $9,000 for a cosmetic overhaul to $28,000 for reconfiguring the entire footprint and moving plumbing.
Cosmetic Versus Structural
A cosmetic renovation replaces surfaces: tile, paint, vanity top, fixtures. A structural renovation moves walls, relocates drains, or changes the shower footprint.
We tell you honestly which one your project is. Some Thousand Oaks contractors blur this line to close a sale, and the result is a renovation that runs over budget the moment the wall comes down. Your written price accounts for what we can see, and we explain what might shift once we open things up.
When Age Changes The Scope
Homes in Conejo Valley neighborhoods built before 1980 often have cast iron drain lines. When we open the floor for a bathroom renovation and find cast iron at the end of its life, that’s when the written price and the conversation both get updated.
You won’t get a surprise invoice. You’ll get a phone call and a decision to make together.
Small Bathroom Remodel

A Small Bathroom Remodel covers powder rooms, hall baths, and compact guest baths that run 25 to 50 square feet, where every inch of layout matters. You need it when a cramped bathroom is holding back the whole home’s usability, or when you’re planning to list in a Thousand Oaks market where updated bathrooms genuinely move a sale. Mason Remodeling Co Thousand Oaks specializes in making small bathrooms feel and work bigger without moving walls: recessed niches, wall-hung sinks, corner showers, and mirrors cut to exact dimensions. Small bathroom remodels in Thousand Oaks run from $5,000 for a focused refresh to $12,000 for a complete fixture, tile, and vanity replacement.
Storage That Doesn’t Crowd
In a small bathroom, a pedestal sink can be the right call for footprint, but only if you solve storage elsewhere. We build recessed wall niches between studs and specify vanities that trade depth for height when the floor plan demands it.
Every decision gets made with the actual inch count in hand. No product gets ordered until we’ve verified it fits the space.
Compact Fixture Specifications
We specify toilets with round bowls and compact 12-inch rough-ins, shower pans at 32 by 32 inches where space allows, and pocket doors where a swinging door would make the room unusable.
None of this is guesswork. We measure, we plan, and the written price reflects the plan.
Shower Remodel
A Shower Remodel upgrades or replaces an existing shower without touching the rest of the bathroom, which makes it the most contained and cost-predictable project we do. You need it when your current shower leaks past the pan, when tile has lost its bond and sounds hollow, or when you’re simply tired of cleaning grout lines that were sealed badly years ago. Mason Remodeling Co Thousand Oaks performs shower remodels for Thousand Oaks homeowners with full waterproofing to current code, and our shower replacement work runs $3,000 for a direct swap of a standard alcove unit to $8,500 for a custom tile shower with upgraded valve and head.
Valve And Supply Line Reality
Thousand Oaks homes built before 2000 often have original mixing valves with no anti-scald protection. Your shower remodel is the cleanest moment to bring that valve to code.
We check supply lines and shutoff valves while the wall is open and replace anything that would fail within a few years. It adds less than you’d think and prevents a leak inside a freshly finished wall.
Waterproofing To Code
Waterproofing a shower isn’t just a pan liner and green board anymore. We use bonded membrane systems that fully seal the walls and floor before a single tile is set.
This is the part of the job homeowners never see after we leave, and it’s the part that separates a shower that lasts 30 years from one that rots from the inside. This is where we never cut corners.
Tub to Shower Conversion
A Tub to Shower Conversion removes an existing bathtub and rebuilds the space as a dedicated shower, typically with a lower entry threshold, a sleeker footprint, and better water containment than the original tub surround. It’s one of the most common requests we get from Thousand Oaks homeowners who never use their tub but use their shower daily. Mason Remodeling Co Thousand Oaks handles every step of the conversion in-house: demo, drain relocation, valve replacement, shower pan construction, tile setting, and glass. Tub to shower conversion in Thousand Oaks runs from $3,500 for a basic alcove replacement to $10,000 for a fully tiled custom shower with a bench niche and frameless door.
Drain And Footprint Considerations
A tub drain sits at 1-1/2 inches in diameter and a shower drain needs 2 inches under current California plumbing code. We replace the trap and line while the floor is open.
We also check the slab or subfloor for rot around the old tub flange. If the tub has been leaking slowly for years, that’s the moment to address it before it becomes a ceiling repair below.
What To Expect During The Work
Your bathroom will be under full dust containment during the conversion, with plastic zipper walls and floor protection laid down every day. Your toilet stays usable wherever the layout allows.
Most tub to shower conversions in Thousand Oaks take five to eight working days. You’ll know your schedule in advance, and we hit it.
One Day Bath Remodel
A One Day Bath Remodel is a specialized process that replaces an existing tub or shower surround with a new, low-maintenance surface in a single day, using purpose-made panels and trim that install over properly prepared walls. It’s not a full bathroom remodel, and any company that tells you it is should be scrutinized hard. You’d choose it when you need a functional, clean, waterproof shower or tub surround fast, and you don’t want tile, custom glass, or a weeks-long construction process. Mason Remodeling Co Thousand Oaks performs one day bath remodels when the existing plumbing is sound, and these runs start at $3,000 for a direct shower replacement and go to $8,500 for a tub with premium surround and integrated shelving.
When It’s The Right Call
A one day bath remodel works when your drain and supply lines are in good shape and only the surround has failed. If the valve is leaking inside the wall, a one day product won’t fix it, and we’ll tell you that before you spend anything.
In Thousand Oaks rental properties and guest baths that need to be back in service fast, this is often the most practical solution. You lose one day instead of two weeks.
What The Warranty Actually Covers
We put every one day bath remodel under the same written guarantee as our full renovations, with coverage terms stated in plain language. That’s 365 days from the completion date under our Done Right Promise.
If a repair or installation fails, you get a free return visit. No charge, no dispute process, no conditions. That applies to every project we complete, not just the big ones.

AfterBrands We Service
Our bathroom remodels regularly include fixtures and surfaces from CGI, CWS, ES Windows, and ECO Window Systems. We’ve worked with CGI windows specifically on bathroom projects where natural light and privacy need to be balanced, and their frame profiles match cleanly with tiled shower surrounds.
ES Windows products come up often when a Thousand Oaks homeowner wants a larger bathroom window with the thermal performance to handle Conejo Valley summer heat without condensation on cool mornings. Whether you have any of these brands, or a mix of older windows and hardware, we integrate them into the remodel, order the correct replacement parts, and make sure the final installation looks native to the room.
If your bathroom has no windows at all, we can also discuss adding one with ECO Window Systems or CWS, provided the structural scope makes sense for the project.
Signs You Need a Pro Right Now
- Soft spots in the floor around the toilet or tub. This signals a long-term slow leak has been rotting the subfloor. Ignoring it means the repair gets more expensive every month and the floor can eventually fail.
- Grout that stays dark or damp hours after a shower. Water is getting behind the tile and causing mildew in the wall cavity. Surface sealers will not solve a moisture problem behind the tile.
- Mold stains on the ceiling below the bathroom. The shower pan or tub drain is leaking into the joist bay. Left alone, this becomes a structural repair and a health issue.
- A toilet that rocks or shifts when you sit on it. The toilet flange is broken or the floor is compromised. Continued use can crack the toilet and worsen subfloor damage.
- Shower valve that won’t fully shut off or drips constantly. That’s wear on a valve that’s likely original to the home. It’s a plumbing repair waiting to become a flooded bathroom.

How Much Does Bathroom Remodeling Cost in Thousand Oaks?
A typical full bathroom remodel in Thousand Oaks runs $9,000 to $28,000, with a small bathroom remodel falling between $5,000 and $12,000 and a walk in shower installation between $4,500 and $12,000. Those numbers reflect a moderate finish level with quality fixtures from names like Kohler and Moen, standard tile, and proper waterproofing. If you’re adding a curbless shower, moving plumbing, or choosing floor-to-ceiling stone in a larger master bath, you’re moving toward the top of the range, and rightfully so.
What affects your price: the square footage, whether walls move or drains relocate, the tile you select, the glass enclosure type, and what we discover once the walls open. Homes in Lynn Ranch and North Ranch built in the 1980s tend to hold fewer surprises than midcentury homes in the Conejo hills, but every house is different. The way to avoid overpaying is to get a written line-item price, confirm it includes permits and hauling, and compare against another written bid, not a verbal number. Your free estimate from Mason Remodeling Co Thousand Oaks includes the full scope in writing. No one starts a tool until you approve the number.
