basement shower rough-in

I am installing a shower kit in my basement. There is a rough-in already, which is located in a square hole in the cement floor about 11" x 11" to accommodate the p-trap. Do I need to fill this hole with cement or sand after I install the floor pan? The floor pan is quite sturdy (Maax Cosmos model). Also, there is a very slight wobble when I place the floor pan on the cement floor...what is the best way to eliminate this? Otherwise the floor is quite level except for this minor wobble.

Welcome to the forums. If you fill in the hole, only use sand, as you may have to get to it again someday. The best thing to do is put 4 large dollops of thinset under the shower pan in the corners (since the hole is in the middle), and squish down on the pan to firm up the bottom. It will take out the wobble and give the floor a solid feel.
