Fast, Reliable Bathroom Remodeling Across Placentia
Bathroom remodeling in Placentia typically costs $9,000 – $28,000 for a full remodel, with smaller projects like a tub-to-shower conversion running $3,500 – $10,000. Most jobs take 2 – 6 weeks depending on whether we’re moving walls, replacing drain lines, or working around a 1960s cast-iron stack that’s seen better days. If you’re planning a bathroom remodel in Placentia, call (803) 680-2547 and we’ll give you a written price before any work starts – not a verbal estimate that grows on the final bill.
We know Placentia’s housing stock. Most homes here were built between the 1950s and 1970s, and that means something specific when you open a bathroom wall: galvanized steel supply lines, cast-iron drains, and vent stacks that may not meet current code. Our Bathroom Remodeling team has seen every version of that surprise, and we scope for it up front so you’re not blindsided mid-job.
Why Mason Remodeling Is Placentia’s Preferred Bathroom Remodeling Company

Mason Remodeling has been doing general contracting and bathroom work since 2004 as part of the Threshold Group family. But the reason Placentia homeowners call us isn’t our history – it’s how the crew shows up. Every technician is background-checked and identity-verified under The Threshold Standard. Before anyone steps into your home near Tri-City Park or off Yorba Linda Boulevard, you receive their name and photo. When they arrive, they’re in a clean marked uniform with a photo ID badge at the door. No mystery subcontractors, no “some guy will be there Thursday.”
Homeowners in Placentia – especially those who are often home alone, parents with young kids, or older adults – tell us that’s the deciding factor. You should know exactly who is walking through your door. We put that in writing, the same way we put prices in writing. A written price is delivered before any work begins on every project, whether it’s a small bathroom remodel in a 1958 tract home near Golden Avenue or a full walk-in shower installation in a newer development off Rose Drive. That’s not a promotion. It’s how we operate.
Every completed project is also covered by a written guarantee with plainly stated terms: what’s covered, what’s excluded, and for how long. If the work isn’t right, our 365-Day Done Right Promise means we fix it at no cost to you. A live person answers our phone 24/7, including weekends and holidays. No call trees, no voicemail loops.

Small Bathroom Remodel in Placentia
A small bathroom remodel in Placentia runs $5,000 – $12,000, and in homes from the 1950s – 1970s it almost always involves more than swapping a vanity and calling it done. The typical job includes replacing the toilet, vanity, and flooring; installing a new shower valve and surround; and updating lighting and a fan. But before we price it, we open the wall at the supply lines and the vent stack. That’s the difference between a quoted number you can count on and a change order that lands after demo.
The Pre-Pricing Inspection
We don’t give a final written price for a small bathroom remodel in Placentia until we’ve looked at what’s behind the existing tile. Galvanized steel supply lines from the 1960s often crumble when touched. If they’re present, we include replacement in the quote from day one – not as a surprise add-on later. That’s why our prices hold.
What “Small” Actually Covers Here
In a Placentia hall bath, a small remodel might mean a new shower valve, a Kohler toilet, a 30-inch vanity, and tile up to the ceiling around the tub or shower. Most of these jobs take 7 – 14 days once permits are approved. We’ll walk you through what’s included line by line before you sign anything.
Shower Remodel in Placentia

A shower remodel in Placentia ranges $3,000 – $12,000 depending on whether you’re replacing a shower pan and valve or converting a tub to a walk-in shower. For homes in neighborhoods like Alta Vista or near Craig Regional Park, the biggest cost driver is what’s under the shower – especially when a 1962 cast-iron drain has rusted through under the slab.
Walk-In Shower Conversion
The most common request we get in Placentia is a tub-to-shower conversion, and the honest range is $3,500 – $10,000. For older homeowners, a low-threshold walk-in shower removes a fall hazard. For growing families, it frees up bathroom space. We install a pre-sloped shower pan, a Moen or Kohler valve, and tile the surround to ceiling height. Permits and inspection are included in our price.
Frameless Glass and Finishes
Frameless glass shower enclosures usually add $1,200 – $2,800 on top of the shower base and tile. We work with specification-grade partners like Cambria and Silestone for custom vanity tops and Schluter strips – that’s the metal trim that seals the edge where tile meets flooring. It’s a small detail, but it’s one of the first things that leaks when cut corners age.
Trusted Brands We Service in Placentia
We install and service professional-grade fixtures from Kohler, Moen, and Toto, and we work with cabinetry lines like KraftMaid and Wellborn for vanities. For Placentia customers, that means we’re not limited to whatever’s on a shelf at a big-box store. If you’ve spec’d a specific Moen valve or a Silestone vanity top, we’ll order it and schedule the install. We also coordinate with modular housing partners like Mighty Buildings and Dvele when a Placentia homeowner wants a prefab ADU with a full bath. One crew, one written price, one schedule.

AfterCommon Bathroom Remodeling Problems We See in Placentia Homes
- Galvanized steel supply lines that crumble during rough-in. Homes built before the mid-1970s around Placentia are full of them. If a contractor doesn’t open the wall before pricing, you’ll get a change order when the pipe shatters. We scope for it up front and include it in the written price.
- Undersized or rusted vent stacks. The original 2-inch vent in a 1960s tract home near downtown Placentia often can’t handle a larger walk-in shower. Inspection fails, the project stalls, and the price creeps up. We check the vent before we rough in.
- Cracked cast-iron drains under the slab. In Placentia’s older homes, the drain pipe running under the bathroom floor may be original. A cracked pipe means jackhammering, replacing the drain, and re-pouring concrete – a real cost that should be in the bid or flagged before demo.
- Unrealistically low allowances for tile and fixtures. Some contractors quote a bathroom remodel in Placentia with an allowance that only covers builder-grade tile. When you pick a porcelain tile and a Moen valve, the price jumps. We set allowances at real market levels from the start, so your fixed price stays fixed.

FAQs About Bathroom Remodeling in Placentia
Yes. Any work that moves plumbing, changes the shower valve, or alters the drain line requires a permit and inspection in Placentia. We pull permits and schedule inspections for every project. If a contractor tells you a permit isn’t needed for a shower replacement, walk away. Call (803) 680-2547 and we’ll explain exactly what your project triggers.
A small bathroom remodel in Placentia usually takes 7 – 14 days of active work. A full bathroom remodel with tub-to-shower conversion and slab-level drain work runs 4 – 6 weeks, including permit approval and inspection sign-off. We’ll give you a written schedule with your written price before any work starts.
The big three in Placentia are galvanized steel supply lines, cracked cast-iron drains under the slab, and undersized vent stacks. Homes built between the 1950s and 1970s all have one or more of these. We open the wall and inspect before pricing, so those costs are in the original written quote – not a change order. Call (803) 680-2547 for a free estimate that accounts for what’s actually behind your walls.
Yes, as long as the vanity framing, supply lines, and shutoff valves are in good shape. In older Placentia homes, we sometimes find shutoff valves that haven’t been turned in 40 years and won’t seal. We’ll tell you if the existing vanity can stay, and the quote for just the shower work will reflect that. Estimates are free.
We install Moen, Kohler, and Toto fixtures; Cambria, Silestone, and Caesarstone vanity tops; and KraftMaid or Wellborn cabinetry. If you have a specific brand in mind for your Placentia remodel, we’ll order it to spec and include it in the written price. Call (803) 680-2547 with your wish list and we’ll get you a number.
