What you might be thinking of is a drum trap. Basically (in modern times) a plastic can with side inlet and discharge. Not used much except in tight situations or when frequent access is needed to retrieve lost objects.
Naw, I looked at those, definitely not a drum trap.

Are you looking for a HepvO waterless trap? I have one in my shower and it works great and it is low profile!
I looked at that last night while searching for low profile shower traps, my only concern is when it comes time to replace it after the membrane has become stiff and no longer functions it won't be accessible without having to tear out part of the floor as it would be located underneath the shower pan.
