hi - hoping to get all your expertise here. I want to put a neptune wind whirlpool only tub in the far corner of my bathroom. My contractor can accommodate the 3 to 6 inch overjet of the motor in the wall and I will need to have the access panel in the garage which is the other side of the bathroom wall. My question for the group is - how big will this wall access have to be? Right now he is saying it is too tight as he has to put the furnace in the garage right up against the bathroom wall - but I am thinking that there has to be a way? How big is the motor and how much would I need to have a) in overall opening dimensions and b) workable depth/clearance on the garage side to be able to change it out. Trying not to give up on my dream :)

Would appreciate any help you can give me.
