Interior Door Buying Guide: Types

Interior Doors - Types

Standard interior doors - panel or flush doors - come in slab form or as a prehung door unit. An associate at The Home Depot store near you can answer your questions and help you choose between slab and prehung doors.

Slab Door


  • Good choice if only the door needs to be replaced
  • Framing not included
  • Old door is taken off its hinges, and the new one is hung in place
  • Hardware (doorknobs, handles and locks) sold separately



  • Good choice if the door and framing must be replaced
  • Door comes already attached to hinges and to door framing
  • Existing door and framing are removed, and the prehung unit is installed
  • Hardware (doorknobs, handles and locks) sold separately

When you choose The Home Depot to install your interior doors, we'll make sure they fit perfectly. If necessary, we'll trim them so they open and close properly.
