Cost to Basement Bathroom Addition in Providence, RI (2026)
If you’re budgeting a basement bathroom addition in Providence, most projects run $7,449-$21,282, 6% above the $12,500 national average. What moves that number most is usually one thing: Below-Slab vs. Macerating System.

Easiest place to save: Start with a half bath (toilet and sink) instead of a full bath - you get 70% of the functionality at 50% of the cost.
