A spa standing outdoors cools down and catches leaves and dust the moment the lid comes off. You pull this Bestway EnergySense cover over the whole tub, from the top panel right down the side wall.
The cover is built in two layers: an insulating layer that holds the heat in the water, under a waterproof outer layer of DuraPlus material that stands up to rain, sun and daily use.
There is a zip along the side. It lets you draw the cover over a clipped-on pump unit, or pass the hoses of a separate pump through, without disconnecting the spa first. The cover clips onto the tub, so it stays put in a strong wind.
Measure your spa before you order: this version is square and fits models of 201 x 201 cm with a wall height of 80 cm. The colour is grey.
