Before work starts
A bathroom remodel needs a building permit once it involves moving the toilet, shower or tub drains, new wiring or a fan circuit, or changing walls. In West Windsor, historic review can come first when the work shows outside: a new or bigger window, an exhaust-fan vent through an outside wall or the roof, or a bump-out.

Planning
What we quote for bathrooms: a refresh $10,586 to $22,810, a guest or hall bath $22,810 to $33,649, and a primary bath $33,649 to $48,906. Your exact price comes in a written scope after our visit.
Leaving the toilet, shower and tub where they are keeps the price down. Moving drains is where bathrooms get expensive.
Waterproofing behind the tile and a fan that vents to the outside matter more than any tile you pick.
Pick the fixtures early, because the plumbing rough-in is set to them.

If the work changes the outside of the house, such as a new or bigger window, an exhaust-fan vent through an outside wall or the roof, or a bump-out, the historic review in West Windsor Township can apply first. Work inside the house is a matter for the building permit. Check whether your house is in a historic district before anything is ordered.
