First it is best to source your spa cover from a reputable company that has a wide selection of spa covers. You can be assured that they sell enough covers that they will use materials that will last. What looks like a really great deal now may look more expensive in twelve months time.
Spa cover prices: Good quality spa covers under 2.4m will cost you between AU $450.00 and AU $750.00 and you should be cautious of anything below that because sub standard materials are most likely being used. Swim Spa covers will cost more.
