Frequently Asked Questions
How much does a bathroom remodel cost in NJ?
Nationally, the median major primary bath remodel was $18,000 for rooms under 100 square feet and $30,000 for larger ones in 2025, according to the 2026 U.S. Houzz & Home Study. The bathroom cost guide has the Middle Atlantic figure and what moves the price.
Do I need a permit for a bathroom remodel?
A like-for-like fixture swap is ordinary maintenance under N.J.A.C. 5:23-2.7. Moving a drain, adding circuits or changing the layout needs a construction permit.
Can you add a bathroom where there isn't one?
Yes, in a basement, under stairs or in other space, as long as the plumbing can reach it. New plumbing needs a permit and a licensed plumber.
