  • Two tubs - two problems.

    I ordered this tub because I only saw positive reviews. For the price it is a decent hot tub, but both spas that I received would not hold air. Overstock was great and paid to ship them both back, but what a hassle it was to set them up and then to dismantle them and get them back into the box for return. When I called about the first one, I asked how often this happens, and the young man checked and said that probably 4 out of 10 had issues with holding air or being inflated. Maybe all those folks did not write a review, but it makes me wonder. I would think twice before ordering this product. Also it is not a Therma Spa, but a Thera Spa, and there is no contact information whatsoever in the directions.

  • DONT WASTE YOUR MONEY!!

    Had the tub two months, the motor died. It was still under the 3 month warranty, so the company had me ship the motor back to them in Florida, free, and they fixed it. It worked for a month and died again. This time the warranty was over so I had to pay to ship it back to Florida this time. They fixed it again and shipped it back. Worked for another month and has died yet again. They want me to ship it back again. I said no. I will go to another company and find another hot tub. When the tub worked it was great. But the amount of time it was not working wasnt worth the money or the trouble. Not to mention, each time it had to be drained and refilled. So my water bill went way up after filling it three times in five months. I will try another company!

  • Perfect for 2

    One person was able to put it together with very little effort. Make sure it is spread out evenly before you fill it up. Other reviews said it takes 2 days to heat up and that is also very accurate. You would have to know the other two people very well to make this a 4 person spa.

  • Inflatable Portable Hot Tub

    I still haven't made a final decision on this product. It was wonderful in the summer time but as soon as the temps started to drop it could not hold temp. I really like 103 degrees so was disappointed when exterior temps of 60 caused it to be too cool. I've put it away for winter, seeing no way to keep it to temp. If it works in the spring I'll consider myself a winner. I'll update my comments then! There is no padding to speak of on the bottom so placing the tub when empty upon an insulation blanket helps.

    graphicpartner from san Juan Island Washington,

  • nice but maybe not for every day usage

    This is the second of a very simular product that we've had. The first one had the heating eliment go bad within a week. You have to pay very close attention to your opperating times and to the water chemestry. We keep ours set up for use every day - but sometimes we feel more like we are babysitting it than using it - but it's all worthwhile when we get in it. The only other thing of note: The bubble function (is also the apparatus that blows it up) is pretty loud - it sounds like a shop vac.

Thank you for contacting us, water must be replaced every 90 days. MFG recommended Chlorine only, What we recommend is to walk in to a local Pool Store and bring a sample of your water, they will tell you exactly to the ounce what to pour in. The water is filled by Garden Hose and emptied from the bottom of the Motorbox, there is a threaded cap to unload the water. When opening ensure your rubber plug is still in the drain floor of the spa so you don’t have a flood. Please let me know if you have any further question. overstockcustomercare1 on Feb 15, 2013

I have just purchased this spa and am very happy with the product with one exception. After the tub was filled with air & water. we used it and then it sat over night. By morning it was quite deflated and I had to pump more air for about 2 minutes into it. Then about another 7 hours later I had to pump air in again for about 1 minute. Is this a normal loss of air or might there be a leak? There is no sign of a leak and it is on pavers that were swept very clean. mslao2000 on Apr 25, 2012

Use a standard spa chemical set using a bromine or chlorine sanitizer. You can buy the kits on amazon or at any pool/spa store. If you don't use any chemicals it will get very moldy and full of bacteria very fast due to the high temperature.
