Cantabria Reviews

We Love Our Cantabria

We love our Cantabria hot tub. Water care is so easy. The 5 different spa seats are wonderful to choose from. The lounge is perfect. We love the sequencer on the lounge.

Great Hot Tub!

We purchased this tub two years ago and couldn’t be happier! After a long day a good soak feels great on the back and on the feet. Several jets target different muscles on different seats.
