Shop Design Build · updated 2026

A finished basement can add a family room, a guest suite or a place for hobbies without an addition. The fun ideas only work if the basics are right first.

Popular uses

  • Family and media room.
  • Guest suite with a bathroom; see the basement bathroom guide.
  • Home gym or playroom.
  • Wet bar for entertaining; see wet bars.
  • Home office or workshop.

Moisture first

Fix drainage and dampness before finishing. Moisture-resistant materials and a dehumidifier keep a basement comfortable. See basement finishing.

Egress and code

A bedroom in a basement needs a proper egress window or door. Finishing usually needs permits; see remodel permits in NH.

Light and floors

Basements lack daylight, so layer recessed, wall and task lighting. Luxury vinyl plank handles moisture well; see hardwood vs LVP.

Plan and price

Sketch the space in the 3D floor planner and see the basement finishing cost guide.

Common questions
