80 * 80 Inch Hot Tub Mat, Extra Large Inflatable Hot Tub Pad Outdoor Indoor, Waterproof Slip-Proof Backing, Absorbent Spa Pool Ground Base Flooring Protector Mat (80 * 80 Mat-Square)

Love this mat, dries quickly, doesn’t get moldy and is the perfect size to fit under our blow up squares hot tub. Leaves enough room for our slippers to sit on for when we get out! Great price and quality! Very durable!

This mat works perfectly under my blowup hot tub. Even gives a little Cushion.

I love my hot tub. It was money well spent. No issues with it at all. The bubbles rapidly reduce the temperature, but even a hard side tub will do this. It does take planning.....if it's really cold outside it'll take longer to heat, but it does do a good job holding heat once it's up to the temp you want. I do wish it came with a little seat or something so you can sit higher out of the water if you want. It definitely will make your electric bill go up depending on how much you run it. (About $40/mo for me)I run mine all the time though. I keep the temp set at about 80 or 85, then set it on 104 in the morning if I plan to use it that evening.

I have to say I was not excited about this purchase when my wife brought the idea forward. The reason are many, but the investment was minimal in the grand scheme of things, and at least gives us an idea of whether or not a larger investment in a permanent solution is worthwhile. I was wrong. My family has truly enjoyed this in the few weeks since we set it up. It very easy to setup, works well, and does what we want it to do. The max temperature is 104, so if you want it hotter, that is the max. There is also no way this will fit seven people. Maybe three or four (small) adults max, but for a small family or someone seeing a few minutes on their owner with one other person, it's perfect. As for durability and longevity, we will see, but so far so good. The app is intuitive and allows you to control the pump remotely. Overall, this is a win.

Recommended. I have this placed directly on my cement patio which is working just like it's supposed to do. My hot tub is on top of a foam type cushion with this product on the very bottom. I think it will help my hot tub keep it's warmth better in the winter rather than being directly on the cement.

Fit under my new hot tub perfectly and protects it from the concrete beneath it. Dries quickly when water gets on it. Color is perfect as it blends with the hot tub. Price was also a bonus!

Thinner than i expected, but it worked for us during summer.

This hot tub has been great! I’ve had it for 4 months now and it heated up good and has stayed at temperature even through the cold weather.
