AfterFast, Reliable Bathroom Remodeling Across Antioch
A full bathroom remodel in Antioch typically runs $9,000-$28,000, with most walk-in shower and tub-to-shower conversions falling between $3,500 and $12,000 depending on whether your home’s slab and framing need work before tile goes up. We’re Rowan Construction Group, and our crews work the east Antioch tract neighborhoods and the older Delta-waterfront pockets with the same process: inspect first, write the price, then build. Dispatch and scheduling run from our San Francisco Bay Area office, but the crew that quotes your Lone Tree or downtown bath lives local and knows what opens up when you pull the drywall. Call (510) 686-6370 to schedule your free estimate.
Why Rowan Construction Group Walnut Creek Is Antioch’s Preferred Bathroom Remodeling Company
We’ve delivered 4,000-plus projects since 2007, every one with a written price before work started and a documented photo record when the crew left. In Antioch, that discipline matters more than most places.
Our Bathroom Remodeling team knows the difference between a 2004 Deer Valley stucco tract on a cut-and-fill pad and a 1952 downtown wood-frame with original knob-and-tube. The first needs a slab evaluation before you spec a shower pan; the second needs a permit strategy before you remove a wall. Customers in Antioch tell us the three-star reviews they read mention exactly this: contractors who opened the walls and disappeared, or quoted low and invoiced high. We don’t do either. Under Clause 1 of The Haven Standard, the price is written before anyone starts. Under Clause 3, no change proceeds without a signed change order. That’s why our projects finish within a few percent of the number you agreed to.
A live person answers our phones 24/7. Our technicians are background-checked, uniformed, and arrive with a photo documentation kit as standard. Grant Rowan built this system after watching too many homeowners left with verbal promises and no paper.
Our Bathroom Remodeling Services in Antioch
Full Bathroom Remodeling
A full gut in Antioch means different things on different sides of town. In east Antioch’s 2000s subdivisions, we start with a slab assessment-expansive Yolo clay beneath those post-tension pads heaves through 100°F summers and wet delta winters, and a shower pan installed over a deflecting slab cracks within a season. In older neighborhoods near the waterfront or downtown, we budget for electrical rough-in upgrades and load-bearing reviews that the permit office will flag once walls open. Our written quote includes allowances for exactly these findings, priced and approved before demolition starts.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Antioch runs $4,500-$12,000, with frameless glass enclosures at the higher end where the slab is sound and the framing is modern. We spec Kohler valves and waterproofing assemblies rated for the thermal cycling this inland delta climate delivers-Antioch’s 100°F-plus days and sharp wet-dry swings stress substrate and sealant differently than cooler coastal zones. Every shower we build includes a flood test and photo documentation before tile covers the work.
Tub-to-Shower Conversion
This is our most called-for service in Antioch’s Lone Tree and Deer Valley tracts. Homeowners bought these homes new 15-20 years ago; the fiberglass tub-shower combos are failing, and the family wants a modern walk-in. Here’s the catch: those tubs were set over post-tension slabs that may have deflected or cracked from clay-soil movement. We evaluate the slab before we quote the conversion. A tub-to-shower conversion in Antioch runs $3,500-$10,000 if the slab and drain rough-in are sound; if soil investigation and crack remediation are needed, we write that as a line-item allowance with a trigger price, not a surprise mid-job.
Vanities, Tile & Fixtures
We source KraftMaid and Wellborn cabinets, Cambria countertops, and Kohler and Toto fixtures across fifty-plus vetted brands. In Antioch’s smaller downtown baths, a floating vanity and large-format tile can reclaim square footage lost to bulky 1960s cabinetry. In east-side master baths, double vanities with quartz tops and heated-floor cable are common upgrades. Every selection is written into the quote with model numbers, not “allowance for vanity-TBD.”

AfterTrusted Brands We Service in Antioch
We stock and install KraftMaid and Wellborn cabinetry, Cambria quartz surfaces, and Kohler and Toto fixtures for Antioch jobs, with supply-chain relationships that keep lead times honest and replacement parts available. In a market where a delayed vanity can stall a bathroom for weeks, that sourcing depth means the written quote contains real numbers, not inflated placeholders. We don’t spec brands we can’t deliver.
Common Bathroom Remodeling Problems We See in Antioch Homes
- Post-tension slab cracking beneath 2000s east-side showers. In Lone Tree and Deer Valley subdivisions, clay-soil heave creates deflection that fractures tile and grout within months of installation. We evaluate slab flatness and structural integrity before quoting any shower work.
- Failed waterproofing in original stucco-era assemblies. Antioch’s wet-dry delta swing and 100°F-plus summers cycle the substrate behind tile until the subfloor rots. We remove backer board to inspect, replace with cementitious membrane systems, and flood-test before closing walls.
- Knob-and-tube wiring and undersized framing in pre-1970 downtown homes. Removing a non-load-bearing wall often reveals electrical that won’t pass modern code. We pull permits that trigger full rough-in upgrades, priced in the original quote as a conditional allowance.
- Shower pans leaking into subfloor for years undetected. By the time tile cracks or drywall stains appear, the damage has spread. Our demolition protocol includes subfloor inspection and photographic documentation of every layer we remove.
Pricing for Bathroom Remodeling in Antioch, CA
These are the ranges we write into quotes for Antioch homes, based on 4,000-plus projects with flat pricing and signed change orders when conditions change:
| Service | Price Range in Antioch |
|---|---|
| Bathroom Remodel | $9,000-$28,000 |

What moves a quote within these ranges? Three things specific to Antioch: slab condition on east-side tracts, electrical and framing age in older homes, and the permit scope triggered once walls open. We don’t guess. Our pre-construction inspection documents substrate, plumbing, and electrical condition with photos, then builds allowances into the written quote for predictable surprises. If we open walls and find nothing extra, you pay the base price. If we find the stair-step fractures or wet subfloor we budgeted for, the trigger price is already approved. No verbal add-ons. No “we’ll figure it out later.”

Our crews work Bathroom Remodeling in Antioch as a core service area, with regular jobs in Brentwood, Concord, Danville, and Pleasant Hill. Each city gets the same inspection-first protocol and written-price discipline, calibrated to local housing stock and soil conditions. Antioch’s 2000s tract boom and expansive clay soils create a remodeling profile distinct from Concord’s older flatland homes or Danville’s hillside construction, and our quotes reflect that difference.

FAQs - Bathroom Remodeling in Antioch
The difference is usually the slab. East Antioch’s 2001-2008 tract homes sit on cut-and-fill pads over expansive Yolo clay that heaves and shrinks dramatically between 100°F summers and wet winters, producing post-tension slab cracking and drywall stair-step fractures most Concord flatland homes don’t experience. We budget soil investigation and potential crack remediation as a standard line item here, not an afterthought. Call (510) 686-6370 for an exact quote on your specific home-estimates are free.
Yes, if the work involves plumbing rough-in changes, wall removal, or electrical modification, which most tub-to-shower conversions do. The City of Antioch Building Division requires permits for plumbing fixture relocation and any structural or electrical work triggered by demolition. We pull permits as standard practice, schedule inspections, and include permit costs in the written quote. Call (510) 686-6370 and we’ll confirm what your specific conversion triggers.
An allowance is a dollar figure written into your contract for work we can’t fully scope until walls open-common in Antioch where slab condition and hidden electrical age create predictable unknowns. We set trigger prices for specific findings: slab crack repair, subfloor replacement, electrical rough-in upgrade. If the condition isn’t found, you don’t pay. If it is, the price is already approved in writing before we proceed. No mid-job negotiation. Call (510) 686-6370 to review how allowances work on your project.
We inspect for knob-and-tube wiring, undersized framing, and foundation settlement before quoting, because removing any wall in these homes typically triggers a permit requiring full electrical upgrade and load-bearing review. A small bathroom remodel in these properties runs $5,000-$12,000 if systems are sound, higher if rewiring and structural work are needed. We document conditions with photos and build the upgrade path into the original quote as conditional allowances. Call (510) 686-6370 for a free inspection and written price.
A straightforward tub-to-shower conversion on a sound slab takes 5-7 working days from demolition to final inspection. If slab remediation or electrical upgrade is needed, add 3-5 days for trade scheduling and inspection sequencing. We don’t rush inspections-Antioch’s building department, like most Bay Area jurisdictions, books 2-3 days out-and we don’t tile over uninspected waterproofing. Your written quote includes a timeline with inspection holds built in. Call (510) 686-6370 to schedule your free estimate and receive a project calendar with your price.
