What a full bathroom renovation actually costs in NYC in 2026 — co-op board approvals, wet-over-dry rules, and real per-square-foot pricing by borough.
Bathroom renovation in NYC costs more than almost any other US market because of building rules, permits, and access. A standard 5x8 hall bathroom in a Manhattan co-op runs $25,000–$45,000, and a primary bath gut in a brownstone or condo runs $45,000–$95,000+.
Co-op and condo approvals add 4–10 weeks before demo starts. Alteration agreements, board review, insurance certificates ($2M–$10M), and licensed plumber filings (LPC for landmarks, DOB for plumbing) are non-negotiable. Wet-over-dry rules in most co-ops force you to keep the new bathroom in the same footprint as the existing one.
Standard NYC bath gut cost drivers: tile (porcelain $8–$25/sf installed, stone $25–$60/sf), vanity ($800–$6,000), toilet/fixtures ($400–$3,000), plumbing rough-in ($4,000–$9,000), waterproofing ($1,500–$4,000), and electrical ($1,200–$3,500).
Brownstone bathrooms in Brooklyn (Park Slope, Bed-Stuy, Carroll Gardens) and Manhattan add structural realities: cast-iron stack replacement, joist sistering, and old subfloor demo. Budget an extra $5,000–$15,000 for the unknown.
