Shower Waste Pump

[Bodd]

Not sure where you are going with this other than the kitchen but you need to make sure the shower waste trap stays full of water.

Could just put the kitchen sink underneath

What I have done in the past is run the waste pipe at ceiling level into a boss that has either been drilled or cut into the stack

Means the shower tray can fit flush on the floor

Subject to postion of any joist of course!

Yes of course. I always rip out old and lift the floor before I buy the tray. Then buy a tray with a waste hole position to suit best.
