So I thought I was set on a Jacuzzi J-470, but it won't work with the way I want to install it. I was planning on surrounding it with stone, and leaving the back open for access. The problem is, on the J-470, the the back of the tub rises up, like a rainbow. That would mean that the opposite side, ( where the controller is, and where you get in ) would have to be open and face the back of the yard. I think that would look stupid. It wouldn't be a huge deal to leave the access covered, but the dealer said the clear ray bulb needs replaced every 18 months. They also said that it isn't that hard to slide it back a foot or so to do it. My question is, do I risk messing up the tub by doing this every 18 months, and does anyone have any other ideas of how to go about this. If I can't figure it out, I may just pass on getting a tub, as this is the only tub that I really liked!
