• the main basin having a peripheral rim for containing liquid in the main basin;
• the main basin having at least a portion of the peripheral rim arranged at a lowered height relative to a prescribed height of the peripheral rim so that the liquid can overflow said at least a portion of the peripheral rim in the event that the liquid reaches a depth greater than that which can be contained in the main basin;
• a liner covering a surface of the main basin up to the peripheral rim in an installed configuration;
• and a secondary basin communicated with the main basin over said at least a portion of the peripheral rim so as to collect all overflow of liquid from the main basin that is directed by said at least a portion of the peripheral rim towards the secondary basin;
• whereby, in the installed configuration of the liner, said at least a portion of the peripheral rim, which is arranged at the lowered height, provides transfer of liquid out of the main basin by overflow while the liner prevents contact of the liquid with the main basin where the patient's feet are received.
