ABSTRACT:
A shower bath, sink, or other fluid receiving vessel is described wherein heat is reclaimed from the drain fluid to warm the incoming cold water to reduce the amount of hot water which must be mixed in to produce water of the temperature desired for use within the vessel. The improvement consists of a cover pan for collecting the received fluid and depositing it on a particular region of the vessel floor which is contoured to direct the received fluid along a particular channel to a drain. The cold water supply tube is positioned within the channel in contact with the draining fluid. The warmer drain fluid transfers heat energy into the cooler water flowing within the submerged cold water supply tube.
