Bathroom Remodel Cost Guide for Greater Charleston Homeowners
Bathroom remodel pricing across Greater Charleston spreads more than most homeowners expect. The same square footage in an 1850s South of Broad single house, a 1960s Avondale brick ranch, a 1990s Old Village or Park West Mount Pleasant build, a 2010s Cane Bay or Nexton subdivision home, and a barrier-island beach house can land $5,000–$20,000 apart. What drives the spread is demo scope, the shower system, whether plumbing has to move, and how much salt-air and humidity exposure the bathroom sees.
Typical Greater Charleston price ranges by project type
These are reference ranges for professionally installed, permitted projects from full-service remodelers. Historic Downtown Charleston stock (South of Broad, French Quarter, Harleston Village, Ansonborough, Radcliffeborough, Cannonborough-Elliottborough, Wagener Terrace, Hampton Park), Old Village Mount Pleasant, historic downtown Summerville, and barrier-island beach houses typically land at the higher end of each range because of subfloor moisture, plaster walls, undersized vent fans, original cast-iron drains, BAR review timelines on the peninsula, and flood-elevation considerations on the islands.
- Tub-to-shower conversion (existing footprint, acrylic): $7,500 – $14,000
- Walk-in shower replacement (acrylic, semi-custom): $9,000 – $17,000
- Walk-in shower (tile build-out, custom): $14,000 – $30,000
- Full bathroom remodel (layout unchanged): $12,000 – $24,000
- Full gut remodel (plumbing relocation, new layout): $18,000 – $45,000+
- Accessibility-focused conversion: $8,500 – $26,000 depending on features
What drives the cost up or down in Greater Charleston and the Lowcountry
Demo scope matters most. A clean swap inside a Mount Pleasant, Daniel Island, Cane Bay, Nexton, Carnes Crossroads, Summers Corner, The Ponds, Hamlin Plantation, Park West, Carolina Park, Dunes West, Rivertowne, or Shadowmoss framed alcove is the most predictable scope. A South of Broad single house, a Harleston Village Greek Revival, an Ansonborough Federal, a Cannonborough-Elliottborough Charleston double, a Wagener Terrace bungalow, an Old Village Mount Pleasant cottage, or a long-tenure Avondale or Riverland Terrace brick ranch can add $2,000–$8,000 before the shower system goes in — especially when the original bathroom sits over a damp crawlspace and the drain has to be re-routed.
Tile is the other big swing. Acrylic systems install in 1–3 days; tile runs 1–3 weeks because waterproofing, mortar, and grout each need dry time. Lowcountry humidity, salt air on the barrier islands, and Charleston Water System moderately hard water shape long-term finish choices.
- Scope of demo: surface vs. down-to-studs
- Shower system: acrylic insert vs. semi-custom acrylic vs. tile
- Plumbing: stay in place vs. move drains/supply lines (crawlspace re-routes vs. slab cuts)
- Subfloor and joist condition (historic peninsula stock and barrier-island beach houses often need repair)
- Vent fan rework — undersized or attic-vented fans common in older intown and island stock fail faster in Lowcountry humidity
- Permit and disposal fees (vary by City of Charleston, North Charleston, Mount Pleasant, Summerville, Goose Creek, Hanahan, Moncks Corner, plus Charleston / Berkeley / Dorchester counties)
- Charleston Board of Architectural Review (BAR) review on peninsula and historic-district exteriors
- Barrier-island flood-elevation, salt-air, and hurricane code considerations (Folly Beach, Sullivan's Island, Isle of Palms, Kiawah Island, Seabrook Island)
- Hard-water and salt-air finish choices (brushed nickel and PVD finishes hold up better than polished chrome on the coast)

Frequently asked questions
What's the most common Greater Charleston bathroom remodel?+
A tub-to-shower conversion inside the existing footprint, especially across Mount Pleasant (Park West, Carolina Park, Dunes West, Hamlin Plantation, Rivertowne, Brickyard Plantation), Daniel Island, Cane Bay, Nexton, Carnes Crossroads, Summers Corner, The Ponds, Legend Oaks, Goose Creek, Hanahan, and the long-tenure West Ashley and James Island brick ranches. Acrylic conversions in framed alcoves are 1–3 day installs and the lowest-risk scope in the region.
Do contractors need a license to do bathroom remodels in South Carolina?+
Plumbing must be performed by a South Carolina-licensed plumbing contractor (SC Department of Labor, Licensing and Regulation / LLR Contractors Licensing Board). South Carolina also licenses residential builders / specialty contractors at the state level (LLR Residential Builders Commission). The City of Charleston, North Charleston, Mount Pleasant, Summerville, Goose Creek, Hanahan, Moncks Corner, and the three approved counties each pull their own permits and inspections for work that moves drains or supply lines. On the Charleston peninsula and in designated historic districts, exterior-visible work also requires Board of Architectural Review (BAR) approval. Verify the LLR plumbing license, residential builder license, and the permit pull before signing.
