This sauna provides more space than the BSA2402 model comfortably seating two people spaciously. One interesting feature with this sauna is the inclusion of an oxygen ionizer which allegedly purifies the air and decreases molding. Another unique feature to this model is the chromotherapy option, meaning a color changing lighting reported by some to be mentally beneficial. Other features to set this sauna apart are the CD player, radio, and aux input, back rests, towel hooks, and a magazine rack. This sauna is again made of Canadian Hemlock and is attractively designed.
