AfterFast, Reliable Bathroom Remodeling Across Corte Madera
A full bathroom remodel in Corte Madera typically runs $9,000 – $28,000, with tub-to-shower conversions landing between $3,500 and $10,000. The number climbs or falls based on what’s behind the walls, and in Corte Madera’s flatland neighborhoods, that’s a bigger variable than most homeowners expect. Our crews work throughout Corte Madera weekly, and when you call (936) 259-2607, a real person picks up and schedules your free written estimate. No voicemail maze.
Why Penhallow Remodeling Is Corte Madera’s Preferred Bathroom Remodeling Company
Corte Madera homeowners deal with a specific kind of remodeling reality: homes built on former tidal marsh fill, with the moisture and settlement issues that come with it. We know what’s behind the 1950s and 60s drywall in the flats, and we price for it before demolition starts. That’s the difference between a quote that holds and one that balloons after the tile comes down. Each of our technicians arrives in uniform, background-checked, and ready to explain what substrate means if you ask.
Our Bathroom Remodeling team operates under the Kingswell standard, which has been the foundation of the Kingswell family of companies since 2004. Every Corte Madera bathroom project gets a written price before work begins, a defined arrival window, and the 365-Day Done Right Promise: if it’s not done right, we come back and fix it at no charge for a full year. That commitment is in writing on every job. Homeowners who have been through a remodel that cracked, leaked, or ran 40% over budget recognize what that’s worth.
Another thing: dispatch for our San Francisco Bay Area office coordinates Corte Madera jobs locally, so response is measured in days, not weeks. You’ll get a date, a window, and the same crew from start to finish.
Tub to Shower Conversion in Corte Madera
A Tub to Shower Conversion in Corte Madera means pulling out a bathtub and rebuilding the footprint as a walk-in shower, and on 1960s-era tract homes in the flats, the job almost always includes plumbing corrections you can’t see from the surface. Homeowners in neighborhoods like San Clemente Drive and along Tamalpais Drive call us when the tub is too low to step into safely, or when the original cast-iron drain has quietly corroded into a slow leak. In Corte Madera, the price typically lands between $3,500 and $10,000 depending on what’s underneath.
Subfloor and Flood-Zone Adjustments
Many flatland homes sit on post-and-pier crawl spaces over bay mud. That means the subfloor has often settled out of level, and the drain rough-in may need re-routing before the new pan sits correctly. On FEMA Zone AE parcels, the Town of Corte Madera’s local amendment requires finished floor elevation 1 – 2 feet above Base Flood Elevation, which can demand reframing the subfloor before the first tile goes down.
What the Crew Actually Installs
We build the shower pan on a cement board substrate (the moisture-resistant layer behind your tile), set the drain at the corrected elevation, and waterproof with a sheet membrane. For the glass, we install frameless enclosures in standard sizes and custom cuts. Fixtures from Kohler and Moen are standard options because their warranties track with our own.
One Day Bath Remodel in Corte Madera
A One Day Bath Remodel in Corte Madera compresses the visible work into a single working day, and it works best when the existing layout doesn’t need to move. If the footprint stays put, our crew can remove the old tub or shower, re-board, waterproof, and set a new system in a day. Corte Madera homeowners choose this when the bathroom is the only full bath in the house and shutting it down for two weeks isn’t workable. Expect $6,000 – $12,000 for most configurations.
What Qualifies for One Day
The one-day path requires a dry, sound subfloor and a drain location that doesn’t need to move. On flatland homes with settled floors or saturated joists, we may recommend the slower route. We’ll tell you honestly which one yours is during the estimate, and the price you’re given is the price you’ll pay unless a surprise requires a written change order.
Why It Still Needs a Permit
Corte Madera permits for bathroom work on flood-zone parcels aren’t optional. Even a one-day replacement can trigger the elevation review. We pull the permit, note the finished floor height on the plans, and schedule the inspection. It’s faster when the paperwork is right the first time.
Trusted Brands We Service in Corte Madera
We install and service cabinetry and fixtures from KraftMaid, Kohler, Moen, Delta, and Toto, along with Cambria and Silestone quartz countertops. For prefabricated and panelized approaches that some Corte Madera homeowners ask about, we’re familiar with what Abodu and Cover produce and can coordinate bathroom fit-outs within those systems. Local parts stock in Corte Madera means less waiting on backordered trim kits. When a Moen valve needs replacing mid-project, we don’t burn a week waiting for freight.
Common Bathroom Remodeling Problems We See in Corte Madera Homes
- Rotted subfloor from original waterproofing failure. The 1960s tile on many flatland homes was set over drywall or greenboard, not a true waterproof membrane. Once the tile is off, the framing underneath is often black with mold. That’s a line-item allowance, not a surprise.
- Corroded cast-iron drains in slab-on-grade homes. Corte Madera’s persistent fog and salt air accelerate pipe corrosion. We find cast-iron waste lines reduced to a quarter of their original diameter on many remodels. Replacing under-slab plumbing adds $1,500 – $4,000 depending on distance to the stack.
- Out-of-level floors from bay-mud settlement. Differential settlement is common on the flats. A bathroom floor that slopes 3/4 inch over five feet means the new shower pan must be corrected or the glass won’t hang square.
- Flood-zone elevation surprises at permit review. Homeowners often draw a standard bathroom remodel and only discover at the permit counter that the Town requires the finished floor 1 – 2 feet above Base Flood Elevation. That forces a redesign. We check this before the drawings go in.

FAQs About Bathroom Remodeling in Corte Madera
The difference is the foundation and the flood zone. Corte Madera’s flatland homes sit on former tidal marsh fill with bay mud underneath, which means out-of-level floors, subsided crawl spaces, and the occasional cracked slab. On FEMA Zone AE parcels, the Town’s local amendment requires the finished floor 1 – 2 feet above Base Flood Elevation, which can force subfloor reframing and drain re-routing. Inland towns like San Anselmo don’t carry that same dual compliance burden. Call (936) 259-2607 for a written quote that accounts for your specific street and parcel.
Yes. Any bathroom remodel that modifies the plumbing or the finished floor elevation pulls a permit in Corte Madera. We handle the permit, the drawings, and the inspection coordination as part of the job. The flood-zone elevation review is triggered on many flatland parcels, and getting that right before demolition avoids a redesign later. Estimates are free, and we’ll tell you what your specific address triggers.
You pay the line-item allowance we wrote into the original contract, and we replace the affected framing and waterproofing before moving forward. On a 1962 tract ranch off San Clemente Drive, our crew opened a hall bath and found a partially subsided post-and-pier crawl space, a corroded cast-iron drain, and the original slab cracked from differential settlement. None of it appeared on the as-built. We wrote each fix as a line item, priced it, and got written approval on a change order before demolition crossed the inspection threshold.
If your existing finished floor already meets the Town’s elevation requirement, a one-day remodel proceeds without reframing. If it doesn’t, we need to bring the floor up 1 – 2 feet above Base Flood Elevation before the new pan and drain can be set. That adds framing and plumbing scope, and we’ll know which path your home needs during the estimate. Call (936) 259-2607 and we’ll check your parcel before we quote.
Yes, especially on the flatland tracts built between the 1950s and early 1970s. Decades of differential settlement over bay mud have left many homes with out-of-level floors and subsided crawl spaces. We write a contingency allowance into every Corte Madera bathroom contract so the number on day one already reflects the likely reality behind the drywall. You approve any surprise in writing before we touch it.
