What Our Clients Say
Why Charleston Homeowners Choose Us
Plan the bathroom you need before choosing finishes
A shower conversion, a hall bathroom refresh and a primary suite remodel need different scopes. Start with what stays: the room layout, tub, vanity and plumbing locations. Then list what changes, including shower waterproofing, ventilation, lighting and any repairs exposed during demolition. Our walk-in shower guide helps you compare a focused conversion with a complete bathroom renovation.
Ask how long the bathroom will be unavailable and whether your household needs another usable bathroom during construction. Review the bathroom renovation sequence before agreeing to a start date, and use the remodel cost guide to separate the room budget from other work in your home.
When comparing estimates, match the scope, selections, allowances, permit responsibilities and treatment of concealed conditions. If the project includes supply or drain changes, discuss the plumbing scope with the bathroom work. Fixed-price and cost-plus contracts are available depending on the project; request a written estimate for your address and selections.

Compare bathroom costs by room size and scope
The Remodeling 2025 Cost vs. Value Report — Charleston, SC provides two distinct reference projects.
Existing 5-by-7-foot bath — about $27,000: the midrange project updates a 35-square-foot room with replacement fixtures, a tub and tile surround, vanity counter, medicine cabinet and ceramic flooring. This involves more work than painting and changing a vanity.
Expansion inside the house — about $83,000: the upscale project expands a 35-square-foot bathroom to 100 square feet within the existing house footprint and relocates fixtures. It includes a separate shower and soaking tub, two sinks, upgraded storage and lighting, ventilation, HVAC extension and heated flooring.
These Charleston figures are regional context, not a separate Charleston price survey. These are not two finish levels for the same room, a minimum-to-maximum range or a 2026 Southeastern Renovation quote. A shower-only conversion, accessibility changes, different room size or addition outside the house needs its own measured scope and estimate.

What should a bathroom estimate include?
Start with the room dimensions and a sketch or photos showing the existing tub, shower, toilet and vanity. Decide whether the fixtures will stay in place, whether you want a shower-only conversion, and whether the room needs to grow.
- Demolition, disposal, protection of adjacent rooms and final cleanup.
- Shower base and waterproofing system, tile area and installation pattern, shower glass and ventilation.
- Named fixtures and vanity selections or clearly stated supply allowances, plus installation.
- Plumbing and electrical changes, framing or subfloor repairs, and how concealed conditions will be assessed and approved.
- Permit and inspection responsibilities, access to another bathroom, product lead times and the agreed construction sequence.
A useful budget separates required repairs from optional finishes. Compare the same inclusions, exclusions and allowances across proposals; the lowest total can cover a smaller scope. Request a written estimate for your address and selections.
Plan the cost around your scope and location
Compare a refresh, a shower conversion and a full room remodel. Specify layout changes, waterproofing, tile, glass, ventilation and any subfloor repairs so estimates cover the same work.
Compare the West Ashley bathroom guide or Rock Hill bathroom guide, then find the guide for your location.
Published research benchmarks describe only the room sizes and scopes named in each guide. Confirm your address, selections, allowances and exclusions in a written estimate. Fixed-price and cost-plus contracts are both available depending on scope.
