I am tiling a shower and the plumber put the membrane down over the level floor.Am I okay to just slope the mortar bed for the tile? Also, can the mortar be applied directly to the rubber membrane? Thanks.

Go to this link to see how a shower pan mud base with liner should be done.

Yours is not done correctly.

Thanks. That was the link that I looked at that raised the question. So in order to get it right I will need to pull up the membrane? Or is there any way around that? Matt

Sorry, your going to have to remove the liner and some of the backer board if that was installed.

Right, and tell the plumber how he should have done his work.
