I know this is old but I wanted to post for future people who come looking for answers to the same question.
The following is from Waterbirth Internationals website and was written about the Birth Pool in a Box
"Is there any danger of the pool falling through my floor?
In over 6,000 pool rentals, we have never had a pool fall through the floor. The weight of the pool is equivalent to 4 large adults sitting around a table. Water weighs 8.2 pounds per gallon, so once filled, the pool weights approximately 840 pounds."
An AquaBorn is a little large capacity at 170 gallons so 6 large adults sitting at a table is probably a great visualization.
