Very easy to maintain. A friend and neighbor recommended me to Barefoot Spas. We swore against the idea of a hot tub for years after our first experience. We had a cheap one we got on special at a store near our old neighborhood. We had a lot of problems with it. Mainly in the way the water heats up and it was really hard to et the chemicals balanced. Our Barefoot Spa has been a breeze to own and operate. We do not use a lot of chemicals, which that alone was enough for us to buy it. Also, the maintenance is close to nothing. We’ve had it for almost a year and haven’t had to rain the water yet.
