How much does a bathroom addition cost in North Charleston?
Adding a bathroom in North Charleston costs $4,400–$49,600. A half bath (toilet + sink, ~35 sqft) runs $4,400–$2,900. A full bath (60–80 sqft) costs $2,900–$16,200. A master bath with walk-in shower, double vanity, and premium tile can reach $49,600.
Is adding a bathroom worth it in North Charleston?
Adding a bathroom typically returns 50–60% of the cost at resale in North Charleston. Homes with only 1 bathroom gain the most value from a second bath. Half bath additions near living areas have the best ROI — typically $10,000–$25,000 added to home value.
How long does bathroom addition take in North Charleston?
A half bath addition takes 2–4 weeks. A full bath addition takes 3–6 weeks. A master bath with custom tile work can take 6–10 weeks. In North Charleston, allow 2–4 weeks extra for permit approval. Plan for the space to be unusable during construction.
Can I add a bathroom without breaking through walls in North Charleston?
If you're converting existing space (large closet, unused room corner) and plumbing lines are accessible, you may minimize wall opening. However, new bathrooms need supply lines, drain lines, and venting — which almost always requires some wall or floor access. A licensed plumber in North Charleston can advise on the least invasive approach.
