A soaking basin is provided having a base unit, a disposable liner, and a frame nested therebetween to enable removal of the liner from the base unit, even when filled with liquid. In this manner, a user can remove the liner filled with liquid to pour out the liquid and discard the liner, after a treatment has been completed. Thus, the user need not lift the entire soaking basin to pour out liquid. In addition, the user can use the frame to support the new liner while filling it with liquid, and to transport the filled liner to the base unit to service clients.
