The exposed shallow seal P trap bath waste sits underneath the bath waste. The shallow seal design means the whole waste and trap sits comfortably above floor level.It is often used in conjunction with our exposed bath shrouds & exposed bath waste and plug or exposed Pressflow waste.If the waste pipe is visible and runs above the floor, our Exposed bath extension waste pipe can be used with it. If the waste turns into the floor (S trap) rather than exiting through the wall (P trap) then our Exposed S trap should be used rather than the P trap.
