A seat lift (20) for use in association with a bath (2) comprising a bath base (4) and at least one side wall (6,8,10,12), the seat lift (20) comprising a seat (22), a seat back (24) hingedly connected to the seat, a torsion spring (44), and a guide means (60,64,66) adapted to guide the seat in reversible movement between a lower position in which the seat is close to the bath base and an upper position in which the seat is remote from the bath base characterised in that the guide means is configured so that movement of the seat between the lower and upper positions comprises both vertical and lateral movement of the seat relative to the base of the bath； the seat back may move between a first seat back position in which the seat back is substantially upright and a second seat back position in which the seat back is orientated relative to the seat so that a user sitting on the seat and with their back on the seat back is leaning backwards； the torsion spring biases the seat back to rotate around the hinge connecting the seat back to the seat toward the first seat back position； the torque exerted by the torsion spring is smaller when the seat is in the lower position than when the seat is in the upper position.
