Floating hot tub blankets are one of the easiest and cheapest ways to save money on spa operation. This type of blanket is usually thermal and is placed on the water surface in your hot tub or spa, in addition to the normal hard cover, when the tub is not in use. There are many benefits associated with this type of spa cover which have made them extremely popular among many hot tub owners.
Floating thermal blankets are usually made of closed cell foam with a thickness of 1/4" and a density of 2lb. Because the cells on the foam are completely closed, it will not absorb any of the water from your spa. The material is cut to the size of the water surface in your tub and placed in between the water and your hard cover when you are not using the tub. Many hot tub owners use these covers and have many positive things to say about them.
There are a number of styles to choose from when it comes to these types of spa blankets, however most styles end-up producing the same results. The look of your cover is basically irrelevant since you never really see the cover on your tub. If you are thinking of purchasing a floating spa blanket for your hot tub you can expect to pay anywhere from $25 to $50 or possibly more, depending on the make and style. Overall, floating hot tub blankets have been proven to be a great addition to any hot tub or home spa.
