My husband has owned a few hot tubs in his time, but I never have. It took me a while to make my decision. I wanted tomato sure the spa has everything I need (water massage for arthritis symptoms along with sciatic nerve issues). We decided to purchase the Barefoot Spas PL8. It is a great spa. My husband says it is twice as good as the other spas he owned. The PL8 has certification for therapy. We love it. The lounge is great for focusing on my sciatic issues. all the other seats in the spa feel great. The main thing is it reduces inflammation in my joints. I am in less pain as a result. The ozonator is built in to the spa and it does not require maintenance. We like that. We use a lot less chemicals that I thought we would. I recommend Barefoot Spas, especially the Barefoot Spas PL8 if you are having to manage pain on a daily. It has been fantastic for us! I also want to mention the customer service has been a delight as well. They have helped us with a few things my husband couldn’t figure out.
