Rated 5 out of 5 by from Two years later After owning our Atlantis gold spa for over two years now this is what we have experienced. Maintance take only a couple minutes a day to wipe down and check the water balance. Our electric bill has not gone up to where we even noticed. The operations of our pumps and jets are the same as it was the day it was delivered. My wife and myself enjoy using it 5-6 nights per week. We purchased this spa for hydrotherapy as well as time to spend together, and it has done just that. We are very pleased with the performance, and very glad we made this purchase.

Rated 5 out of 5 by from Life Changing Experience My husband and I purchased The Atlantis in June. We received the Atlantis in July. The entire experience went flawless. Jeff from Houston did our site visit and was awesome. He knew exactly what we were looking for. Mark from CT was very accommodating. He walked us through the entire process. The delivery was also seamless. We both have busy lives and normally don't take much down time together. Since we have gotten the spa we sit together every evening in the spa and enjoy each others company. Your Customer Service Team has been so helpful with all of our questions on maintaining the water in the tub. Thank You ThermoSpas. We are already talking about our "next" Spa. You are #1 in our minds!

Rated 5 out of 5 by from our very first ever spa I am giving this spa a all 5 rating only because i cannot go any higher. We purchased this spa for hydro therapy, as well as family time, along with relaxation. It delivers just that. This spa will massage your neck, upper.middle,and lower well as your hips, thighs,calves, knee and feet. Not to mention the quality time my wife and myself spend with each other. We enjoy every night. Our spa is equipped with thermozone and our water is clear. The bubbling system, and Led lighting. We ordered it in black opal with Nantucket Gray cabinet. From the site inspection,to sales, to financing, to delivery it just could not have gone any smother. Its easy to see why Thermospas achieved all of those awards.

Rated 2 out of 5 by from Our Thermospa We bought this a year ago but have not been happy with it as we feel we had a better product in Arizona and with having a concrete pad, electrical and a crane to deliver it, it was much, much less than this spa.

My husband works a swing shift and after night shift, enjoys relaxing in the spa listening to his favorite music and tends to sleep better after a good soak.
