Quick answer: For bathroom budget planning in Downtown Charleston, JLC/Zonda's 2025 Charleston, SC reference projects cost approximately $27,000 to update an existing 5-by-7-foot bathroom, and $83,000 for an upscale project that expands a 35-square-foot bathroom to 100 square feet within the existing house footprint and relocates fixtures. These are two different scopes, not the endpoints of a universal price range. These Charleston figures are regional context, not a separate Downtown Charleston price survey.

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 Downtown 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.

Plan your Downtown Charleston bathroom scope
These local planning options can differ from the two reference projects above. Decide which features belong in your written estimate:
New vanity, new tile, new tub or shower and fixtures, within the existing footprint.
Freestanding tub, frameless shower, double vanity, stone or large-format porcelain, with the waste and supply reworked to modern falls. Our separately published Harleston Village master bath project was $48,000. That individual project has its own scope and is not a JLC reference project or market average.
Curbless shower with linear drain, heated floors, book-matched slab, custom vanity, water closet, and period-appropriate trim and hardware.
Ask about demolition, disposal, waterproofing, fixture supply, plumbing moves, ventilation, permits and concealed repairs. Use the bathroom estimate checklist to compare proposals with the same scope.

What affects the cost of a bathroom remodel in Downtown Charleston?
Second-floor bathrooms in peninsula houses are the ones that surprise people. The floor structure is usually undersized by modern standards, the waste line runs somewhere inconvenient, and the room below is often finished. We open, survey and price the structure before committing to a layout rather than after. Every shower pan is flood-tested and built on a Schluter or Wedi assembly — old heart-pine framing gives no second chances on a leak. Bathroom scope also depends on shower size and waterproofing, tile and glass selections, vanity and fixture choices, ventilation, and whether plumbing locations change. Existing subfloor or supply-line repairs should be priced for the room after assessment, with concealed conditions addressed in the written scope.
How long does a bathroom remodel in Downtown Charleston take?
Bathroom remodels in Downtown Charleston typically take 2–5 weeks. A guest/hall bath is 2 weeks; a primary suite is 3–4 weeks; a luxury primary with structural changes runs 5–7 weeks.
Do I need a permit or HOA approval for a bathroom remodel in Downtown Charleston?
Downtown Charleston requires a residential remodel permit for any structural, plumbing, or electrical work. Interior finish-only work sometimes qualifies for a minor-repair exemption. HOA/DRB approval depends on your specific subdivision. Southeastern Renovation handles all permit filings and HOA/DRB submittals on your behalf as agreed in the project scope.
