A manually driven bathtub lift for assisting persons of limited strength or mobility into or out of a typical bathtub without the high costs associated with pneumatic, hydraulic or electric lift devices. A seat is attached to a wheeled trolley arranged for movement up an inclined track mounted on a base frame. A chain is disposed about a drive sprocket and a set of guide pulleys and attached to opposite ends of the trolley. The set of pulleys includes an idler that is biased to retain tension in the chain. The drive sprocket is driven by the rotation of a driver wheel supported on the same shaft as the sprocket. Rotation of the sprocket drives the chain which in turn moves the trolley and attached seat. The driver wheel has handles circumferentially spaced around it and is of large enough size that it can be reached and operated from the seat. The lift is light to allow for easily installation and removal and does not require significant strength to operate
