A removable trap for lavatory sinks is provided to enable new technologies to be incorporated into just the water trap portion of the sink trap to maximize the performance of the trap in infection control, while at the same time preserving the trap performance features demanded by major building codes. While a traditional P-trap requires the removal of the entire trap for cleaning or replacement, the removable trap presented in this application allows for easy removal of just the U-bend portion of the trap. The U-bend containing the water is the most vulnerable to attack to cleaning chemicals as well as the most effective locus of innovation in materials and methods employed to reduce infectious bacteria forming biofilms within the lavatory trap.
