AfterFast, Reliable Bathroom Remodeling Across Concord
If you’re looking for a General Contractor in Concord, bathroom remodeling typically runs between $9,000 and $28,000 depending on the size of the bath, the condition of the slab beneath it, and whether you’re moving plumbing or keeping the existing layout. Most full remodels here run four to six weeks, though a One Day Bath Remodel on a smaller hall bath can wrap in a single day when the footprint stays put. We work all over Concord, from the 1950s tracts off Clayton Road to the newer builds east of Highway 242, and we give you a written price before any demo starts. Call (936) 259-2607 to schedule a free estimate.
Why Penhallow Remodeling Is Concord’s Preferred Bathroom Remodeling Company
Trevor Nash set up Penhallow Remodeling to solve the problem Concord homeowners describe most: a contractor who gives a verbal number, then revises it after the first wall comes open. We don’t work that way. Every Bathroom Remodeling project in Concord starts with a written line-item quote, and the number on day one is the number on the final invoice unless you approve a change in writing first.
Our crews know Concord’s older slabs and tight lots because that’s what we see every week. We know a ranch near Ellis Lake tends to have different subfloor problems than a two-story off Cowell Road, and we plan around it. Each technician is background-checked, uniformed, and accountable to a schedule we agree to before work begins.
Every job carries the 365-Day Done Right Promise in writing. If something fails inside a year, we return and fix it at no charge. That’s not a verbal promise. It’s on the contract.
One Day Bath Remodel in Concord
A One Day Bath Remodel is the smart play for Concord homeowners who need a functional upgrade without weeks of dust and a porta-potty in the driveway. We keep the existing tub or shower footprint, replace the tub, surround, valve, trim, and sometimes the vanity top in a single work day. On a small hall bath in Concord, this typically runs $5,000 to $12,000 depending on fixture grade and whether we find subfloor trouble once the old tub comes out.
What gets replaced in a day
The tub or shower base, the wet-area surround, the mixing valve and trim, the drain assembly, and the caulk lines that actually seal the room. We do not move plumbing or flip fixtures in a One Day job because the permit and rough-in work doesn’t allow a single-day finish.
When a Concord home is a good fit
If your slab is sound and the tile walls aren’t hiding water damage, a One Day Bath is genuinely one day. If we find rot or a failing mudsill, we stop, show you photos, and give you a written change order before we go further. No guessing, no surprise invoice at the end.
Bathroom Remodeling Contractor in Concord
As a full-scope Bathroom Remodeling Contractor serving Concord, we take jobs from a single walk-in shower conversion up to a complete gut-and-rebuild with moved drains, new electrical runs, and structural repair. Most full bathroom remodels in Concord run $9,000 to $28,000. A small bathroom remodel on a 5×8 hall bath often lands between $5,000 and $12,000. A walk-in shower installation typically runs $4,500 to $12,000, and a tub-to-shower conversion usually comes in between $3,500 and $10,000.
Full-scale work, planned around older slabs
On Concord’s post-war ranch homes, a bathroom remodel is rarely just tile and fixtures. Many of these slabs were poured directly on expansive Diablo clay with no vapor barrier, so we check moisture and slab condition before we set anything. That investigation changes what we quote and how we schedule.
Written pricing and the draw schedule
You get a written price before any work starts, and we agree on a draw schedule tied to completed phases: demo, rough-in, close-up, finish. No payment for work we haven’t finished. That’s the Kingswell Way, and it’s been the standard since 2004.
Trusted Brands We Service in Concord
We specify products from trade brands we trust because the materials carry their own warranties alongside ours. For Concord bathrooms, that means Cambria, Silestone, and Caesarstone countertops; Kohler, Moen, and Delta fixtures; KraftMaid and Wellborn cabinetry. Our supply runs through Bay Area distributors, so ordering a Kohler Purist valve for a Concord job doesn’t mean a two-week wait.
Common Bathroom Remodeling Problems We See in Concord Homes
- No vapor barrier on older ranch slabs. Many homes built between 1955 and 1975 in downtown Concord and along the Monument Corridor sit on slabs poured directly over adobe clay with no moisture barrier. Tile debonds and vanities swell when that moisture migrates up.
- Aluminum wiring in the bath circuit. Original 1960s electrical systems often have aluminum branch circuits that don’t meet current code for GFCI protection and high-draw fixtures like heated floors or body sprays.
- Mudsill rot where the shower sits on an exterior wall. Concord’s wet winters and hot, dry summers stress slab edges. Water that wicked into a mudsill years ago may still be there, quietly rotting behind the tile.
- Tight site access with a one-car driveway. Staging a full remodel on a narrow Concord lot takes planning. Where the saw, dumpster, and material drops sit is part of the quote.
Pricing for Bathroom Remodeling in Concord, CA

What moves the number isn’t the cabinet finish. It’s what we find underneath. A slab moisture test, a sewer line video check, or a mudsill repair on a Monument Corridor ranch can add $1,500 to $4,000 to a quote that looks cheaper from a photo. Contractors who skip the test quote lower, then hand you a change order after demo. We’d rather show you the real number up front. Call (936) 259-2607 for a free, written estimate.

FAQs About Bathroom Remodeling in Concord
Because those homes sit on unreinforced slabs poured over expansive Diablo clay with no vapor barrier, and the first thing a proper remodel does is test what’s under the tile. In a newer Concord house with a post-tension slab and a vapor barrier, we can often start setting tile the same week. In an older Monument Corridor ranch, we may need to cut a test hole, dry out a wet slab edge, or replace a rotted mudsill before reaching the new tub set. That work is real, and it’s line-itemed on the written quote.
It changes site logistics, not just cost. We price for one driveway bay: material deliveries staged for the correct day, debris removed same-day or in a scheduled bin that comes and goes, and hand-carry for awkward material like full sheets of cement board. On party-wall remodels near downtown, we follow Concord noise ordinance hours and give the neighbor written notice before saw work starts. It costs more to manage, but it’s a line item, not a mystery. Call (936) 259-2607 to get an exact quote on your lot.
Yes, any remodel that moves or alters plumbing, electrical, or structural elements requires a city permit in Concord, with inspections at rough-in and close-up. We pull permits on every job that needs them. On a one-day fixture swap where the existing plumbing stays put, a permit is usually not required, but we will still verify the installation meets current code and tell you exactly what we did.
Often yes, but only if the existing hot and cold supply lines and waste arm are solid. On an original 1960s Concord home with galvanized steel supply lines, the internal pipe diameter is frequently rusted down to a trickle, and a new valve won’t fix that. We inspect the plumbing before committing to a one-day scope. If the waste arm or supply is compromised, we’ll give you a written price for the rough-in work and schedule the finish on a days-matter timeline, not a one-day promise.
With a defined site plan before the first wall comes out. Demo debris goes into a bin that’s scheduled, not parked. Cutting happens in one spot, usually the driveway bay, with a dust barrier hung at the bath door and a HEPA vac running. Every day ends with a clean sweep of the path to the street. If the job runs near a shared wall, we tell the neighbor the work window before day one and keep hammering and sawing to Concord’s permitted hours.
