What affects the cost of a bathroom remodel in Sullivan's Island?

Sullivan's Island Design Review Board has strict compatibility standards — anything visible from a street or beach path is reviewed. Interior-only bathroom remodels usually skip DRB but window replacements do not. We attend DRB on your behalf. Beyond that, the biggest cost drivers are cabinetry material (custom inset vs. stock), counter material (quartz vs. marble vs. quartzite), whether appliances are being replaced, and whether the layout is being reframed (structural work adds $6,000–$15,000).

How long does a bathroom remodel in Sullivan's Island take?

Bathroom remodels in Sullivan's Island 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. Southeastern Renovation includes a $150/day on-time guarantee.

Do I need a permit or HOA approval for a bathroom remodel in Sullivan's Island?

Sullivan's Island 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 part of the fixed price.
