We are just starting the planning for construction of a new home in the Asheville, NC area. My wife swims every day, and we are considering including an indoor pool in the plan so she can use it year round. Nothing fancy, probably just a simple 30' x 10' rectangle without any water features. We have a screen-enclosed gunite pool at our current home, but was wondering whether a fiberglass pool would be appropriate for the new home. Every search I do on the internet on pros and cons turns up someone who is trying to push one or the other. Figured I should turn to the members here to get some disinterested input. The plan is we would be in this home for the next 20 years, so I do want it to last. But I also want to reduce the maintenance burden as much as possible. There could be times when we would be traveling for a month or so, and would like to be able to not to have to worry too much about the water chemistry while we are away. It would be a salt pool, and I have a CO2-based pH control system in my current pool that I would move up to the new home. Would appreciate input on which pool surface is most appropriate for this application. Thanks.
