Welcome to our forum.
For ease of entry, if you can set it up so that the entry step (cool down seat or wherever you first step upon entry) is at the same height as your deck, that may be best. At least that is what I have found...you don't step "up" or "down" into the tub, just lift your leg over the side...easy to balance that way. Just my opinion
How far will it be from the house, or rather the door outside? Mine is about six paces from the master bedroom (part of the reason I bought the house in the first place). I think you'll find the closer it is to the house, the more you'll use it.Just my 2˘ worth.Jim
