Cost to Half Bath Addition in Raleigh, NC (2026)

If you’re budgeting a half bath addition in Raleigh, most projects run $4,484-$13,453, 10% below the $8,500 national average. What moves that number most is usually one thing: Proximity to Existing Plumbing. On its own it can swing the cost by $1,500 - $6,000, so that’s the decision to slow down on before you sweat the smaller stuff.

Easiest place to save: Locate the new half bath on the opposite side of a kitchen or main bathroom wall - shared plumbing walls cut rough-in costs by $1,500-$3,000

In the Southeast (where Raleigh sits): Lower labor costs in most markets; good value region for this type of project.
