The invention specifically provides a surgical irrigation basin having a hollow, insulated bowl-like body, an insulated cover adapted to be attached to the body in liquid-tight relation, and a flanged tube extending from the exterior of the basin to the interior thereof to receive and retain an irrigation syringe. The body and the cover are formed of double wall construction with insulating material sandwiched and sealed between the walls. In the preferred embodiment the insulation comprises a nonwoven fabric bonded between two thin sheets of flexible plastic coated on at least one side with reflective material. Various alternative embodiments and modifications from the preferred embodiment are also provided.
