Our cabanas come with unfinished walls and ceilings so you can complete the interior, if you prefer. We offer to add a beautiful pine tongue and groove 1" x 6" finished interior to both the walls and ceilings. Note that if you are taking delivery of the structure as a kit, you discuss with your design consultant about other interior features such as fans, outlets and switches. you may need to do some wiring and cutting the interior to install outlets. If taking delivery already assembled, you will still need to discuss locations of the fixtures, but upon arrival, all you will need to do is enjoy it.
