Bathroom Remodel Cost Guide for Greater Charleston Homeowners

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, and other nearby areas), 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, and other nearby areas)
• 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, and other nearby areas)
• Hard-water and salt-air finish choices (brushed nickel and PVD finishes hold up better than polished chrome on the coast)
