How many jets for this spa?

16 years ago

We are building a rectangular spa... 42 SF. The long sides measure 7', and the short sides measure 6'. 4 spa jets come standard.

Assuming we only want jets aimed at the person's back:

1. how many jets should we get?

2. how far apart should they be spaced?

3. if we make the long sides 8' instead of 7', does that change the total number of jets?
