Is it difficult to assemble / install?
No, its very simple and can be done in about 30 minutes. The only tool you will need is a screwdriver to attach the door handle. The panels simply latch together and cables connect the electronics between panels. For more details see Delivery, Assembly, & Installation. We recommend that two people, as a minumum, assemble the sauna because some of the panels can be heavy and awkward to move around by oneself.
