When it comes to pools and swim spas, there are four main differences:
Price: The average swim spa installation will cost you about half that of a pool. And don’t forget “hidden fees” that come with a pool such as increased insurance costs or installing a fence.
Space: Obviously, a swim spa will have much smaller space requirements than a pool, making it more flexible and convenient.
Operation & Maintenance: With a pool, skimming, brushing, vacuuming, and monitoring chemicals all need to be done at least once a week. Swim spas use fewer chemicals, less water, and less time to maintain, and are far cheaper to heat.
Return on investment: Pools are typically appraised at half their original value and in the Midwest only increase your home’s resale value by six or seven percent at best. Swim spas, on the other hand, are much better at retaining their original value.
