Definitions

  • This disclosure is generally directed to toilet equipment and more particularly to a toilet lid with a decorated surface and a toilet seat.
  • Toilet seats have existed in various forms for many decades. Usually, they comprise a seating board having a circumferential seating surface around a hole that is substantially positioned in the middle and matches the aperture of the toilet bowl.
  • the seating board provides a surface on which the occupant can sit comfortably.
  • such toilet seats often comprise a lid, which may cover the seating board and thus provide a protective cover for both the seating board and the toilet bowl aperture.
