A toilet assembly includes a toilet with a bowl, a rim surrounding the bowl, and a water inlet pipe extending upward from a rear of the toilet, a toilet seat that rests on the rim and has an opening positioned above the bowl, and an attachment connected to the inlet pipe and the toilet seat. The attachment may include a coupling engaging the inlet pipe and a hinge connection connected to the coupling, where the seat is pivotably connected to the hinge connection of the attachment to pivotably mount the seat on the toilet, such that the seat is pivotable about the hinge connection between a raised position and a lowered position. The coupling may engage the inlet pipe such that the hinge connection is positioned and connected to the seat at a location spaced upward from the top surface of the rear of the toilet.
