Quick answer: 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.

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 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.

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 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?
Which authority permits the address comes first. The City of Charleston says so itself: areas such as West Ashley, James Island, Johns Island and Cainhoy include a mix of properties that may or may not be incorporated within the city, and an address outside the city limits is permitted by Charleston County instead, under a different fee schedule and a different portal. We check the city's GIS map before quoting a schedule, and we handle the filing wherever the property actually falls. Inside the City of Charleston every building and trade permit starts with a non-refundable $40 application. As licensed contractor CLG.127339 we pull the permits and coordinate the inspections for the 29412 area.
