Hot tub covers are made with a variety of alternative approaches. There are the market leading "hard" lids made with foam cores. There are Walk On covers, that hold up to 400 pounds. There are "soft" covers and spa covers made with air bladders. When considering which hot tub covers make sense for your environment, be sure to consider the load bearing properties of each.
For the purpose of this article, I will define load bearing as the ability of spa covers to support additional weight, either from snow, animals or children. It is quite important to note, hot tub cover warranties will be voided by a failure of the core. Typically when this happens to the spa cover, the foam core breaks or cracks. As this cannot happen without excessive load, by the definition of the warranty this is abuse and will not be a valid warranty claim.
For tubs installed into a deck, Walk On style spa covers must be considered to address someone accidentally walking across the spa. Walk On covers are made by laminating fiberglass sheets to both the top and bottom of the foam core, inside the cover. Walk On covers weigh around 100 pounds but are among the strongest lids made.
Soft covers and other covers supported by air bladders are not typically recommended for environments that will have a lot of weight, such as from snow. They simply are not designed to have good load bearing characteristics. They are designed more to be inexpensive.
The final option for selecting a lid to handle weight is the traditional foam core hot tub covers. The load bearing abilities of a foam cover are defined by the density of the foam used in the manufacturing of the cover. Most "hard" covers come standard with 1.0 pound foam. Upgrades are available to 1.5 pound and 2.0 pound foam. The 1.5 pound has 50% more material, and the 2.0 pound has DOUBLE the material in the exact same size core. This extra density is what makes a 2.0 pound foam core hot tub cover strong enough to handle a heavy, wet, snow load.
Do not be short sighted and simply select the lowest cost cover. Should you select a spa cover with 1.0 pound foam to save a few dollars, your savings and more will be lost if the lid is broken by weight.
Hot tub covers have a life expectancy of 4 to 10 years. Yes, replacing the spa cover is a part of the ownership of your spa. With this information in mind, put your mind at ease when considering the purchase of your next hot tub cover.
