I'm working on a new design, and my GC and I will be subbing everything out ourselves. I'm trying to decide the dimensions of the spa. We'd like to be able to hold 8 comfortably - here are my questions:
1. Is 7'x9' large enough to hold that many people, given that 8 will be a rarity. It will mostly just be my wife and me.
2. What dimensions should the benches be inside the spa?
3. What water depth should we be shooting for?
