Clayton homeowners deal with something most flat-lot remodelers never see: sloped lots where drain lines and venting don’t run where standard plans assume.

Styles & brands we work with
Shower Remodel in Clayton
A Shower Remodel in Clayton often means opening up a shower that’s original to a 1970s or 1980s tract home and rebuilding it around modern waterproofing standards, new fixtures, and finishes that fit the home’s mid-century character. In Clayton, this work typically runs $3,000 to $8,500 for a shower replacement, or $4,500 to $12,000 for a full walk-in shower installation.
Clayton’s hillside lots matter here. When we open a shower wall on a sloped lot, we sometimes find drain lines that were run at angles standard plans never anticipated. That’s why we inspect the rough-in before finalizing scope. It protects your price.
Waterproofing and Pan Replacement
Most Clayton homes we open up have original drywall behind the tile, not cement board, and shower pans that have been leaking into the subfloor for years. We replace the pan, install proper waterproofing, and check the subfloor before any tile goes down. If the subfloor is rotted or out of level, that gets addressed in writing, not as a surprise.
Frameless Glass and Curbless Design
Frameless glass enclosures are popular in Clayton because they let natural light into smaller bathrooms common in 1970s tract housing. Curbless shower designs work well for older adults who want to age in place. We’ll walk you through options like Schluter strips, the metal trim that seals the edge where tile meets flooring, and explain what each choice means for water containment.
Tub to Shower Conversion in Clayton
A Tub to Shower Conversion in Clayton takes an existing bathtub and replaces it with a walk-in shower. This typically costs $3,500 to $10,000 in Clayton, depending on whether the drain needs to move, the subfloor needs repair, or you’re adding glass enclosures and custom tile.
Clayton’s housing stock makes this a common project. The original tubs in many homes off Ygnacio Valley Road and Marsh Creek Road are cast iron or steel, and the surrounding tile was installed on drywall. When we pull the tub, we often find water damage behind it that was never visible. We document what we find, show you photos, and give you a written change order before proceeding.
What Gets Replaced
The tub comes out, the drain gets reconfigured, and the shower valve is upgraded to meet current code. We install a new shower pan, waterproof the walls, and tile to your selected finish. Kohler and Moen fixtures are common choices in Clayton, and we can show you what works with your home’s water pressure and pipe size.
When the Drain Needs Work
In Clayton’s older homes, the existing tub drain is often too small or incorrectly positioned for a shower pan. Our crew recently finished a bathroom remodel off Marsh Creek Road where the tub-to-shower conversion revealed a cast-iron drain that needed replacement before the new Kohler shower pan could be set. We worked with the homeowner to document the change order in writing, updated the draw schedule, and passed inspection sign-off on the updated rough-in before tiling with Cambria accents.
Trusted Brands We Service in Clayton
We work with specification-grade brands like KraftMaid, Cambria, Kohler, and Moen so Clayton homeowners get materials that last, not whatever’s on sale at the big box store. Our crews are familiar with these product lines and their installation tolerances, which means fewer surprises during tile layout or vanity installation. For Clayton’s mid-century homes, newer brands like Dvele and Abodu are also becoming common among homeowners doing ADU-scale bathroom additions, and we can work with those specifications where they apply. Call (803) 680-2547 to talk through finishes and fixtures that fit your home and your budget.

AfterCommon Bathroom Remodeling Problems We See in Clayton Homes
- Rotted subfloors under original showers. Clayton homes built in the 1970s and 1980s often have shower pans that have been leaking for years, silently rotting the subfloor. By the time you see water stains on the ceiling below, the damage is usually extensive.
- Cast-iron drains that don’t line up with modern shower pans. The original plumbing in Clayton’s tract housing was sized for tubs, not walk-in showers. When we convert a tub to a shower, the drain often needs repositioning, and cast-iron drains frequently need replacement once we open the floor.
- Out-of-level floors on hillside lots. Sloped lots in areas like Clayton Woods and The Preserve can mean the subfloor isn’t level, which throws off tile layout and glass enclosure installation. We check level before we tile, not after.
- Permit and inspection backlogs. Clayton’s building department requires permits for bathroom remodels involving plumbing or electrical changes. If a contractor pulls the permit after demo starts, or skips rough-in inspections, the final inspection can fail and you’ll be paying for rework. We pull permits before demo starts and schedule inspections in sequence.

FAQs About Bathroom Remodeling in Clayton
Yes, you need a permit for any bathroom remodel in Clayton that involves plumbing or electrical changes, which includes most full remodels and tub-to-shower conversions. The City of Clayton’s building department reviews plans and requires inspections at the rough-in and final stages. We pull permits before demo starts, not after, and we schedule inspections in sequence so your project doesn’t stall. Call (803) 680-2547 to ask about your specific project.
A typical bathroom remodel in Clayton takes 3 to 6 weeks once permits are approved and materials are on site. Smaller projects like a shower replacement or vanity installation can take 1 to 2 weeks. The main variables are permit approval timelines, whether the subfloor needs repair once we open the walls, and material lead times for custom tile or glass. We’ll give you a written schedule before work starts and update you if anything changes.
A tub-to-shower conversion removes an existing bathtub and replaces it with a walk-in shower, while a full shower remodel rebuilds an existing shower from the waterproofing up. In Clayton, a tub-to-shower conversion runs $3,500 to $10,000, while a full shower remodel in an existing shower footprint runs $3,000 to $8,500. The conversion is usually more involved because it requires moving the drain and reconfiguring plumbing.
The price can change if we find rotted subfloor, out-of-level framing, cast-iron drains that need replacement, or code upgrades that weren’t visible before demo. That’s why we do a pre-demo inspection of the rough-in before we finalize your written price. If we do find something unexpected, we document it, show you photos, and get your written approval before proceeding. No surprise invoices at the end. Call (803) 680-2547 for an exact quote on your Clayton home.
Yes, we structure payment as a draw schedule tied to project milestones, which is common for Clayton bathroom remodels ranging from $9,000 to $28,000. We don’t offer in-house financing, but we can discuss third-party options and help you understand what your project will cost month by month. The written price you receive before work starts includes the full payment schedule, so you’ll never wonder what’s due next or when.
