What Drives Basement Renovation Costs?
Major add-ons and their impact on your total budget
Full Bathroom
+$15,000–$35,000
A 3-piece or 4-piece bathroom adds significant plumbing, tiling, and fixture costs. Custom tile showers push toward the high end.
Underpinning

Kitchen / Kitchenette
+$10,000–$25,000
A full kitchen with cabinetry, countertop, sink, and appliance connections. Wet bar or kitchenette at the low end.
Egress Windows
+$5,000–$10,000 each
Required for any bedroom. Involves cutting concrete, a window well, and proper drainage — typically $5–10K per window.
Soundproofing
+$3,000–$8,000
Resilient channels, double drywall, acoustic insulation between joists. Critical for rental units to reach STC 50+ rating.
