Fast, Reliable Bathroom Remodeling Across Antioch
Bathroom remodeling in Antioch, CA typically runs between $9,000 and $28,000, and the single biggest factor isn’t the tile you pick. It’s the age of your house. Antioch’s flatlands hold mid-century tracts with original galvanized pipes and cast-iron drains, while the hill subdivisions above Highway 4 trend toward 1980s and 2000s construction. That difference determines whether your remodel is a two-week surface swap or a four-week re-plumb. Mason Remodeling has been handling general contracting and Bathroom Remodeling since 2004, and our crews know which Antioch streets tend to hide what behind the walls. Call (803) 680-2547 and we’ll scope it correctly from the start.
Why Mason Remodeling Is Antioch’s Preferred Bathroom Remodeling Company
We’ve worked baths from the Delta-adjacent flatlands off Somersville Road up into the subdivisions around Dallas Ranch, and we know the difference between a quick vanity swap in a 1990s hillside house and a full gut in a 1950s ranch near Lone Tree Way. That local familiarity matters, because the written price we hand you before any work begins has to reflect what’s actually behind your tile, not what a generic estimate assumes.
Isaac Pruett leads our crew verification: every technician is background-checked, identity-verified, and arrives in a clean marked uniform with a photo ID badge at the door. You get the technician’s name and photo before the visit. The Threshold Standard isn’t a courtesy; it’s how we run every job in Antioch, and it’s a real reason homeowners who are often home alone, or who have young kids, tell us they chose us over a random crew from Craigslist.
Every completed project carries a written guarantee with plainly stated terms. We cover what’s covered, what’s excluded, and for how long, in writing. The 365-Day Done Right Promise means if the work isn’t right within a year of completion, we make it right at no cost to you. No dispute process. No conditions. That’s the standard we’ve held since 2004 as part of the Threshold Group family of home-service companies.
Styles & brands we work with
Walk In Shower in Antioch
A Walk In Shower in Antioch is the most-requested bathroom upgrade we see, especially in mid-century homes where the original tub is cramped and the homeowner wants a curbless or low-curb entry. It typically runs $4,500 to $12,000 in Antioch, depending on whether we’re doing a direct shower replacement or converting a tub. The job involves demo to the studs, plumbing rough-in for a new valve and drain location, waterproofing, tile or solid-surface walls, and a pan with a proper slope to the drain.
Waterproofing and Pan Detail
We wet-test every pan before tile goes down. That’s not negotiable. In Antioch’s older flatlands homes, we often find the subfloor under the original tub has dry rot from decades of slow seep at the tub flange. We address that before any waterproofing membrane goes in. The inspector wants to see the pan hold water, and so do we.
What It Costs and What Drives It
A straightforward walk-in shower replacement in Antioch starts around $3,000 and climbs when you move drains, add a bench or niche, go frameless glass, or switch to a linear drain. A full tub-to-shower conversion lands between $3,500 and $10,000. If your 1960s bath still has galvanized supply lines, we’ll quote the re-pipe as a written line item before we start. No surprises after the wall is open.
Bathroom Remodeling Companies in Antioch
Bathroom Remodeling Companies in Antioch fall into two camps: those that quote a number over the phone and figure it out mid-demo, and those that put a written scope and price in your hand before a single tool comes off the truck. We’re the second kind, and as a General Contractor in Antioch, we treat every project with the same structured process. We’re the second kind. A full bathroom remodel in Antioch runs $9,000 to $28,000, and the spread is driven by house era, drain condition, fixture grade, and whether you’re moving walls or plumbing.
The Written Price Difference
We write the price before work starts. Every time. That means allowances for tile, vanity, and fixtures are set in real dollars, not vague “budget” categories. If we open a wall near G Street and find cast-iron that’s scaled shut, you’ll see a change order in writing with a specific number before we touch the pipe. That’s how you keep a five-figure remodel from becoming a six-figure argument.
Permits and Inspections
If we’re moving a drain, altering plumbing, or adding electrical, we pull the permit. We don’t close walls until the rough-in inspection signs off. Antioch’s building department wants rough plumbing, electrical, and waterproofing visible before drywall or backer board goes up. We schedule those inspections and you get the paperwork. An unpermitted bath remodel is a gift-wrapped problem at resale, and we won’t leave you holding it.
Trusted Brands We Service in Antioch
We work with specification-grade materials Antioch homeowners can actually see before committing. Cabinet lines include KraftMaid and Wellborn. Surfaces come from Cambria, Silestone, and Caesarstone. Fixtures are Kohler, Moen, Toto, and Grohe. Because we carry professional-grade lines directly, we’re not spec’ing whatever the big-box store had on the shelf that week. We keep common trim kits, valve cartridges, and Schluter profiles moving through our Bay Area supply chain so an Antioch job isn’t stalled waiting on a backordered drain assembly. If you’ve got a preferred brand or line, tell us when you call (803) 680-2547 and we’ll build the scope around it.
Common Bathroom Remodeling Problems We See in Antioch Homes
- Galvanized supply lines in flatlands ranches. Mid-century Antioch homes were built with galvanized steel water lines. Fifty-plus years of mineral scaling means low shower pressure, and once the wall is open, patching is false economy. We quote a full PEX re-pipe as a line item.
- Cast-iron drain failure behind the tub. Original cast-iron drains in 1950s and 1960s Antioch homes scale and crack. We’ve pulled tubs where the drain was so choked the shower couldn’t keep up. You won’t see it until demo. We scope for it.
- Hill-subdivision baths with undersized venting. Some 1980s and 1990s builds in the hills cut corners on vent runs. A new shower or moved toilet means the vent stack may need work. It’s routine when you know where to look.
- Tile failures from Sacramento Delta humidity swings. Antioch’s hot dry summers and damp winters mean grout and caulk move more than homeowners expect. We use movement joints and perimeter caulking designed for that seasonal shift, not just any basic install.

FAQs About Bathroom Remodeling in Antioch
Yes. If you’re moving plumbing, altering drain lines, or adding electrical, the City of Antioch requires a permit and rough-in inspections before walls close. What gets inspected: rough plumbing (supply and drain), electrical rough-in, and waterproofing before tile or backer board goes up. We pull the permit, schedule inspections, and don’t close a wall until the inspector signs off. Call (803) 680-2547 and we’ll tell you up front whether your specific scope needs one.
Because 1950s flatlands homes in Antioch were built with galvanized steel supply lines and cast-iron drains. Both are past their service life. A cosmetic remodel becomes a re-plumb once the wall is open, and that is honest additional cost, not a surprise if the scope was written correctly. Newer hill-subdivision homes from the 1980s and 2000s usually have copper or PEX and ABS drains, so the same remodel trends toward the lower end of the range.
A surface-level remodel with existing plumbing locations can finish in two to three weeks. A full re-plumb with drain replacement and subfloor repair, common in mid-century Antioch homes near G Street or Somersville Road, runs four to six weeks to final inspection. The biggest variable is what we find during demo, and our written change-order process keeps you informed on schedule impact at each step.
Three things, and all of them should be written into your scope as anticipated line items: galvanized supply line replacement, cast-iron drain failure, and subfloor rot under the original tub or shower. If we encounter any of them, you receive a written change order with a specific number before work continues. You approve it, or we stop and you decide. No verbal “we’ll figure it out.” Call (803) 680-2547 and ask us how we handle change orders in writing.
Yes. Walk-in shower conversions are a core part of our bathroom remodeling work in Antioch. A tub-to-shower conversion runs $3,500 to $10,000, and a new walk-in shower installation lands between $4,500 and $12,000. The price is driven by whether we’re moving the drain, what waterproofing system your tile requires, and whether you want frameless glass or a curtain rod. The written estimate covers all of it before we start.
