Hi I am remodelling a bathroom and installing a 30inch by 60inch
fiberglass tub and surround, two piece unit. The tub has two small
adjustable bolts in the inside and just the 60inch edge on the near
side that contacts the floor. My question is I have read some place
about a bed of mortar that the tub should sit on. Is this necessary
or could I use expandable foam? Better yet is there a good pictured
doit web site?
