I believe that you meant T2E hall K. You description is correct - right after security, hang a left and the stairs/elevator is tucked in the corner. There are plenty of shower rooms in this lounge. There are also departure lounges in T2E hall L and hall M, both with showers. The lounge in hall L is upstairs and is very large on one level. The lounge in hall M is on two levels and the showers are on the upper level.
