Hi BBQ, The tank is 31" deep and if you take the door off the hinges it will fit thru a 32" front or back door, however most interior doors are 30" if I'm not mistaken. We came in thru the front tiki room door and not the sliding glass door in the rear. You're right about it being a little over 5" on the short leg and 7" on the long leg. This price also includes all the sand and rock(26 buckets if I counted right), uv sterilizer, euro reef protein skimmer, iwaki pump, and a 1 horsepower chiller. I would bring extra buckets if you got them, the sand is heavy
