Quick answer: Plan on about $27,000 to update an existing 5-by-7-foot bathroom and about $83,000 for an upscale job that grows a 35 sq ft bathroom to 100 sq ft inside the house and moves fixtures. Those are the 2025 Cost vs. Value figures for Charleston, SC, checked September 12, 2026: two different scopes, not a low-to-high range, and not Southeastern Renovation quotes. On James Island, subfloor and framing repair over the crawlspace, and which of three permit offices covers the address, move the number. Compare the source and scope.

What does each bathroom budget level include in James Island?
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 James Island 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.

How much does a bathroom remodel cost in James Island SC?
For bathroom budget planning in James Island, 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.

They are third-party benchmarks, not Southeastern Renovation quotes or minimum charges. A limited refresh, shower-only project, different room size or addition needs its own estimate.
What affects the cost of a bathroom remodel in James Island?
Two local variables move a James Island bathroom number: subfloor and framing repair discovered over the crawlspace, and whether the address is inside the city limits or permitted by the Town of James Island (new permits since May 1, 2026, reviewed and inspected by SAFEbuilt) or, if unincorporated, by Charleston County, since the fee schedules differ. Many homes in James Island were built in the 1960s through 2000s, which in a bathroom usually means a floor system over a vented crawlspace, cast-iron or early plastic drain lines, and an exhaust fan that was never really adequate. We look under the house as part of estimating, because a bathroom floor that feels soft is rarely a flooring problem, and rot found before demolition is a line item instead of a change order. If the property sits in an AE or VE flood zone the City of Charleston's usual permit exemptions do not apply at all, and even interior non-structural work needs a permit. 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 James Island take?
Four to six weeks for a standard James Island bathroom, eight to twelve for a full gut with layout changes. Demolition is one to three days, rough-in three to five, and tile five to eight days by itself. Permitting adds time at the front, and inside the City of Charleston the scheduling rule is published: an inspection requested before noon is scheduled one business day out, after noon two. We give you the schedule before demolition.
Do I need a permit or HOA approval for a bathroom remodel in James Island?
Since May 1, 2026, new permits for addresses inside the Town of James Island are issued by the Town, with plan review and inspections done by SAFEbuilt. Parts of the island are inside the City of Charleston and permit with the City; unincorporated parcels permit with Charleston County. A kitchen or bathroom remodel that touches plumbing, electrical, gas or framing needs a permit whichever office it is, and older published advice that "James Island permits go through Charleston County" is out of date for Town addresses. Southeastern Renovation files the permit and any HOA or design-review submittal as agreed in the project scope.
