Well the other tub/shower we put in when I was cleaning it I found CRACKS so it had to come out and be returned. So then we decided to get the spa tub since it was the same price and well...better! LOL
First some mortar and then 4mm plastic over the top (the manual specified to do that) to support the tub.
