We are in the process of getting some bids for a pool and can't decide between getting a pool only or a pool/spa. We live in the Dallas area. If I go with a pool only, I can get some additional water features, etc. The spa really adds quite a bit of cost to the project and I'm trying to determine if this is something that is needed for resale purposes or not? I'm not sure we would use the spa all that much. I have 2 young boys (6 and 8) that will be using the pool the most. I realize that having a spa will probably help extend the time the kids can use the pool on both ends (in the beginning and end of the season).
So I really haven't been considering a spa until recently. If we decide to do this, are there certain things I need to consider? How big, what should the elevation be, # of jets, etc? Does this require an additional pump?
