Are jacuzzi or spa covers standardized?

Answer 1

Let's put it this way.. They are not exactly standardized but they do come in different widths and lengths but limited

Answer 2

There's no "standard" but if you have a common make and model, you should be able to order a replacement, if not from the original manufacturer, then from one of many pool supply companies.

Answer 3

There is all sizes of spas so there is all sorts of covers. You have to measure and order them from the dealer.
