Steam shower membrane / seating question
I'm in a the middle of a remodel and have framed a steam shower on a slab floor approx 4' x 6' in size. My current moisture management plan is 100% Redgard or Laticrete. I'll be putting in a bench as well. Questions:
1) Have any of you used either one of these products in lieu of a regular shower membrane?
2) Is there any real advantage to a bench made of cinder blocks vs lumber. Any construction tips for either?
This is a great forum. Thanks in advance for all your replies.
