Abstract: A urine deflector is designed to be detachably interconnected with a toilet seat of the type having an upper surface designed to support a user and a hole defined through the seat. The deflector includes a stream deflection member designed to deflect a stream of urine into the toilet bowl. The deflection member has a concave deflection surface. A support member is provided that has a generally planar body designed to be supported on the upper surface of the toilet seat. The generally planar body supports the deflection member such that when the generally planar body is placed on the upper surface of the toilet seat, the deflection member projects into the hole in the seat and the concave deflection surface faces a user seated on the seat. The support member also includes an attachment for releasably retaining the generally planar body in engagement with the upper surface of the seat.
