AfterFast, Reliable Bathroom Remodeling Across San Marcos
Bathroom remodeling in San Marcos typically runs $9,000 – $28,000 for a full gut-and-replace, with tub-to-shower conversions landing between $3,500 and $10,000. The number moves based on what’s behind your walls, and in this city, that’s exactly where the surprises live. Trevor Nash and the Penhallow Remodeling team work the hillside tracts of San Elijo Hills, the older ranch homes near downtown, and every stucco-covered subdivision in between. Call (936) 259-2607 for a written price before anyone picks up a hammer.
Why Penhallow Remodeling Is San Marcos’s Preferred Bathroom Remodeling Company
San Marcos homeowners have a specific set of scars. They’ve had contractors quote a bathroom, open a wall, and suddenly the price doubled because of rotted subfloor or corroded rough-in plumbing. That’s the phone call we get most often from this city, and it’s the reason our Bathroom Remodeling process starts with documentation, not demolition. We inspect, write allowances into the contract for real conditions we expect in San Marcos’s 1990s and 2000s housing stock, and any actual surprise gets priced in writing with photos before we proceed. No verbal ballparks. No “trust me” line items. Trevor Nash runs every project file himself, and the 365-Day Done Right Promise is in writing on every job, so if something fails inside a year, we’re back at no charge.
Our technicians are background-checked and uniformed. A live person answers the phone 24/7, including the number above. That’s not a marketing line; it’s how we schedule work in San Marcos, and it matters when you’re standing in a gutted bathroom at 7 p.m. wondering what happens next.
Tub to Shower Conversion in San Marcos
Tub to Shower Conversion in San Marcos usually runs $3,500 – $10,000, and it’s the single most requested bathroom project we do in this city. The older tubs in San Elijo Hills and the mid-century ranches near Mission Road are shallow, awkward to climb into, and often hiding failed waterproofing behind the surround. Removing the tub and building a walk-in shower with proper cement board substrate (the moisture-resistant layer behind your tile) changes how the bathroom works for daily use, especially for homeowners planning to stay in the house through retirement.
What We Find Behind the Tub
In the 1990s – 2000s tract homes across San Marcos, the original waterproofing membrane is often gone or was never properly installed. We open the wall, document the condition, and if the subfloor is soft or the copper supply lines show corrosion, we write a change order with a line-item price and wait for your written approval before we touch it. You see photos. You see the number. You decide.
Cal Fire Zone Requirements
Large portions of San Marcos sit in Cal Fire’s High and Very High Fire Hazard Severity Zones. A tub-to-shower conversion in those areas can trigger requirements for ignition-resistant venting and materials during the permit review. We handle that paperwork and build those standards into the quote from the start, which is why our San Marcos estimates often look different from a comparable job in Carlsbad or Encinitas.
One Day Bath Remodel in San Marcos
One Day Bath Remodel in San Marcos refers to a specific scope: replacing a tub or shower surround, pan, and fixtures without moving plumbing or opening walls that don’t need to be opened. It typically costs between $3,500 and $10,000 depending on the size of the opening and the finish materials. For the right bathroom, it’s a clean one-day job. For the wrong bathroom, it’s a day one with a second day we didn’t plan for, and we’ll tell you which one you have before we quote it.
When It Works
If the existing tub frame is square, the subfloor is solid, and the drain location stays put, a one-day conversion using a Kohler or Moen shower base and a quality surround can be done start to finish in a single visit. Our crew arrives with everything staged, works clean, and hauls the old tub away the same day. You get a written arrival window and a written price before the day starts.
When It Won’t
San Marcos homes built on compacted fill sometimes have slight movement that throws a tub deck out of level. If the subfloor has any softness from a slow plumbing leak, one day becomes two because the rot comes out before new material goes in. We won’t set a shower pan over a compromised subfloor and call it done. That’s how cracked pans happen, and the Penhallow 365-Day Done Right Promise means we’d be back fixing it anyway, so we fix it the first time.
Trusted Brands We Service in San Marcos
We install and service cabinetry from KraftMaid and Wellborn, countertops from Cambria, Silestone, and Caesarstone, and fixtures from Kohler, Moen, Delta, and Toto. We stock common valve cartridges, trim kits, and drain assemblies for San Marcos jobs so a parts run doesn’t add a second day. When we quote a brand, we quote the exact model, and the price includes the factory warranty alongside the Penhallow written guarantee. If a Kohler finish fails inside its warranty period, you get the manufacturer’s replacement and our labor under the 365-Day Done Right Promise.
Common Bathroom Remodeling Problems We See in San Marcos Homes
- Failed waterproofing from the original build: The 20-year-old membrane behind the tub surround is often cracked or missing entirely, and you won’t know until the tile comes down. We document it, price the repair in writing, and replace it with a proper cement board and liquid-applied membrane system.
- Compacted-fill subgrade movement: San Elijo Hills and similar hillside tracts sit on engineered fill over expansive clay. When a wet winter hits, the slab moves a fraction of an inch, and a rigid shower pan or floor tile cracks. We account for this with isolation membranes and proper substrate prep before anything gets set.
- Outdated wiring behind the walls: Opening a bathroom in a 1990s San Marcos home often reveals wiring that no longer meets current code. That triggers a permit-driven electrical upgrade, and if your contract doesn’t have a written allowance for it, the price jumps. Ours does.
- Corroded copper rough-in plumbing: San Marcos’s hard water and the original copper in these homes don’t always get along. Pinhole leaks and green corrosion at the joints are common findings, and we don’t bury them behind new tile. We photograph, price, and replace.

FAQs About Bathroom Remodeling in San Marcos
In San Marcos’s 1990s – 2000s hillside tracts, the original waterproofing, subfloor, and rough-in plumbing are often compromised or outdated, and opening the wall triggers a permit-driven code upgrade that was never part of the original quote. Penhallow writes allowances for these conditions into the contract before demo day, and if the actual repair exceeds the allowance, you get photos and a written line-item price for approval before we proceed. The number changes because the conditions are real, not because the contractor was lowballing you. Call (936) 259-2607 for a quote that accounts for your home’s era and location.
Yes. A full remodel that moves plumbing, changes the shower valve, or alters the drain location requires a city of San Marcos building permit, and homes in Cal Fire’s High and Very High Fire Hazard Severity Zones may also need fire-resistant venting and material sign-offs. Penhallow pulls the permit, schedules the inspection, and includes the fees in your written price. We don’t do unpermitted work, and we don’t ask you to. The Kingswell Way since 2004 has been the same: price in the permit, pass the inspection, hand you the sign-off.
Not necessarily. San Elijo Hills homes sit on engineered compacted fill over expansive clay, and wet winters cause measurable slab heave that cracks a rigid pan set without an isolation membrane or proper substrate prep. It can be a builder’s failure to account for soil movement, or it can be an installation error. We diagnose the difference before we recommend a repair. If Penhallow installed it and the pan fails inside a year, the 365-Day Done Right Promise covers the fix at no charge, including a free return visit. If another contractor installed it, we’ll document the cause and give you a written price to correct it properly.
Yes, when the tub frame is square, the subfloor is solid, and the drain stays put, a Kohler or Moen tub-to-shower conversion is a one-day job for our crew, typically $3,500 – $10,000 in San Marcos. If we find rot or the tub deck is out of level, the job runs longer because the bad material comes out before new material goes in. We’ll tell you which scenario you have during the estimate, before you commit. Call (936) 259-2607 to schedule a free site check.
We write allowances into the contract based on what we expect in your San Marcos home’s age and neighborhood, and any repair outside that allowance is documented with photos and priced as a written change order before work continues. You approve the number, or we don’t do the work. Trevor Nash reviews every change order personally, and no one touches the job until you sign off. The invoice matches the approved total, and the 365-Day Done Right Promise covers the work after the door closes.
