Abstract: A lift apparatus for an above ground spa or pool to enable a handicapped or infirm person access to and egress from the spa or pool without the need for an attendant to assist them. The lift comprises an upright base securely mounted adjacent to one wall of the above ground spa. The base supports a lift arm assembly having a seat mounted thereon. Lift and rotate controls are provided to permit the seat occupant to raise the seat to a fully elevated position above the wall of the spa, to swing the seat and occupant across the wall and to lower the seat to a desired height within the spa. The lift arm is powered by water driven hydraulics which are configured such that the seat can only be pivoted when it is in its fully elevated position above the wall of the spa.
