Installing Shower Base on Unlevel Concrete
Posted by Mike Judy on October 31, 2001 at 17:34:39:
I am trying to finish my basement on my own. I have a shower drain rough in that was done when the house was built. I purchased a 36x48 Fiberglass Molded Shower Base(Mustee's Durabase). I placed the base over the drain rough in and noticed that the base rocks quite a bit due to the slope of the concrete floor. What would be the best way to level just the area under the shower base? Since the underside of the base is webbed, shimming it does not seem to make sense. I think I need to level it with sub floor concrete mix, but what is the trick for leveling a square area like that?

Thank you for your help!
