Abstract: A float tube urinal of the present invention includes a urine inflow mechanism which is typically formed by a condom catheter formed of a condom (or other urinal) with an elongate tube extending therefrom. The condom catheter is connected to a housing with substantially rigid side walls, or sidewalls which, though flexible, are held apart by substantially rigid support structures, to prevent a compressive force from compacting a containment volume defined by the housing. A vent tube is attached to the housing to vent air in the housing as urine is received from the condom catheter.
