Before work starts
What a bathroom in Hopewell needs first
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 Hopewell, 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
Planning a bathroom in Hopewell: what to decide first
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.
- 01
Keep the layout, or move it
Leaving the toilet, shower and tub where they are keeps the price down. Moving drains is where bathrooms get expensive.
- 02
Water and air
Waterproofing behind the tile and a fan that vents to the outside matter more than any tile you pick.
- 03
Then fixtures, tile and storage
Pick the fixtures early, because the plumbing rough-in is set to them.
