Tore out our 40 year old one piece tub/shower and am installing a new tub and 3 piece surround. When dry fitting the tub, the floor is out of level about half an inch over the width and length of the tub. Should I use self leveler or mortar? The tub is a delta 500 with a big plastic grid base under it. It says no mortar bed required, but I gotta get it level
