What do I need to connect the floor drain (in cement in the floor) to the new base? 2 Feb 2000 at 2:03 am #285696 GuestParticipant Hi Ben: To attach a showerbase to the plumbing you willneed a 2″ showerdrain assembly and a 2″ p-trap. You didn’t say what type of piping you where tying in to. Hope this helps. Marty Author Posts Viewing 1 reply thread You must be logged in to reply to this topic.
