I'm used to installing the pressure treated 2 by 4 stringers for the backs of cast iron and steel tubs but I'm not sure if I should use them for fiberglass units. I'm installing a couple dozen Kohler Devonshire whirlpool tubs soon and they are a well contructed unit. I even checked the manual and it advises to set them in mortar and screw them to each stud only...as I've always done. Have any of you guys had trouble in the future by not putting in stringers also?
No announcement yet.
2 by 4 stringers for fiberglass tubs?
