A shower water conservation apparatus (10) that conserves the shower water by storing the initially cooled water that is produced by a hot water source (124). The initially cooled water is routed by a series of pipes and timed valves into a water reservoir assembly (19), such as a bellows (20), where the water is stored for later use. The cooled water from the bellows (20) is timely released and mixed with flow of cold water from a cold water source (126). The mixed cold water is further mixed with the now hot water from the hot water source (124) before the mixed hot and cold water is manually regulated and applied through a shower head (122).
