This sauna is a pleasure to own. It heats quickly and is low maintenance. The unit is made of quality components in the USA. The difference shows when compared to the less expensive cedar or hemlock imports. Assembly requires 2-3 adults, but is straight forward to do. Make sure you place it where you want it because it's difficult to move once bolted together. Delivery leaves something to be desired. It arrives in several boxes, all of which are heavy, and delivery is only to the curb. You may want to offer a cash incentive to the delivery person to get the thing near or inside a door. We didn't and suffered for it.
