If the joist layout permits it, take the 4" right up to near the shower, if possible, dropping the basin waste into it as well. I've just put in a new ensuite over the summer, with about 400mm of 40mm between the shower trap and the 4" drain. Unlikely to ever block, but dead easy to rod if it does.
