Hot Tub Bubble Blanket - 8 x 8 FT 16-Mil Square Pool Spa Solar Cover | Heavy Duty Floating Heat Retaining Thermal Blanket for Insulating Solar Heating

Is doing a great job. Using this until we decide on a new hot tub cover.

We used as a cover for an outside hot tub. It keeps the water very warm, also prevent evaporation. Prevent the leaves an small branches to fall into the water. It's easy to remove and put it back.The blanket was easy to cut to accommodate to the shape of the hot tub.We don't find any issues with some of the bubbles not to be perfect fill with air, it does do the job.Very satisfy with the product.

We had to change to an electric spa heater and it was taking a long time for the spa to heat up. We bought this to see if it would help. It does help, reduces the heat up time about an hour. Better than nothing. It was easy to cut to fit.

It has protected our spa from the sun, reduced the chance of algae and helped us control chlorine levels. I'm sorry I didn't purchase this sooner! Our custom spa is a D shape and this insulating cover was easy to trim to size. It also seems very durable. The bubbles in the cover are like very heavy duty bubble wrap and simply float on the water. Although it just slides on/off the water easily, it's so big I found it a bit difficult to align while putting it back in place.

Great solar cover. I cut it to fit my hot tub. I use it as an added layer of insulation for the top of my hot tub water. Worked out just perfectly!!

This hot tub thermal blanket works great! I bought it to use in our built-in hot tub in the summer, because our regular cover is way too heavy and bulky. This cover is super practical and not only keeps the water warm (which conserves energy), but matches my pool cover and looks good too. It even withstands some pretty heavy wind (it totally stays in place).

This is very thin, but not expensive. I could not find the type we normally have ordered so gave this a try. We have had 3 spas in 35 years and this solar cover was the least durable. It is just fine if you do not need extra protection in the winter. Just a light cover.

Lasted about 1 year and then the bubbles started falling and falling off. Clogging the hot tub filter.Won’t buy again
