If a basement or outside area I would suggest using floor drain instead of a regular shower drain.  A regular shower drain will need a vent run from it wile a floor drain will not need its own vent.  If a upstairs installation you will need to build a pan for the shower using a flange type shower drain,(see image) and connect to a lavatory drain line where it will be wet vented.  Let us hear from you.  Tom
