We would like to install a shower in a bathroom which has a sink and toilet but no rough in for a shower. The problem is that the bathroom has a cement floor which is not cuttable. Any solution for an above ground drainage which connects in the sink/toilet?

It's not that easy Tracy,
You would have to platform the entire shower base and enclosure but also platform the drain line across the floor to the wall where you would have to open up the wall and tee into the lavatory drain line. It's much easier to jack hammer up the floor, do the rough in, install the shower, patch the floor and then tile or vinyl it. Both ways are major surgery and one hellish hassle.
But if you want to give it a shot good luck. Tom
