On this side of the pond every fixture needs a P-trap, but you need to check with your local codes book to be sure. It should be the same. FYI--I have never had good luck locating a laundry too close to a closet bend because the toilet will gurgle when the laundry runs. Further, make sure you contact a professional to insure proper venting of your new fixtures.
