Shower in Basement

I am installing a bathroom in my basement with a toilet, sink, and shower. I purchased a saniflush toilet that will eject the waste from a sink, shower and of course the toilet. My question is getting the waste water to flow from the shower to the ejector. I understand I need a 1/8 inch drop for each foot of run, but that would reduce my headroom in the shower since I would need to build it up. Is there a small pump to move the shower run off to the ejector pump? Or will I have to build the shower up high enough to handle the run to the ejector and the P trap?

Thanks for any advice you can give me.
