How to Install Raised Toilet Seats

Raised toilet seats replace standard seats in order to accommodate anyone with limited mobility.

Improper installation of a raised toilet seat can result in serious injury to anyone using the toilet by causing the person to fall off the toilet. Certain raised toilet seats incorporate handle bars, providing more stability to a user, but do not require additional installation requirements. According to the Canadian Red Cross, adjustable raised toilet seats are not meant to be used long term, since they can come out of adjustment frequently.

Lift up on the covers on the regular toilet seat installed on the toilet, exposing the plastic bolts hidden underneath. Insert a screwdriver into the slots on the bolt heads and grab the nuts located on the other end of the bolts on the underside of the toilet bowl.

Twist the screwdriver counterclockwise until the nuts unthread from the bolts. Remove the bolts from the toilet bowl and lift the seat off the bowl as well.

Turn the adjustment handle on the raised toilet seat counterclockwise until loose, if a handle is present. Place the seat onto the bowl so the tall end of the seat is in the rear and the seat sits on the edge of the bowl's opening, then press down on the seat so it sits firmly in place. If the seat is adjustable, make sure the rear tabs on the seat are inside the toilet bowl.

Use your hands to turn the knob on the toilet seat, if present, clockwise until you feel resistance. Turn the handle another one-eighth of a rotation.

Things You Will Need

  • Readjust the seat on the toilet, if it is adjustable, once a week to avoid the possibility of injury from the seat coming loose.
