A sink extender has a sink comprising a removable drain pan that may be connected to a conduit. An attachment mechanism connects the sink to a support. At least one tool holder supports an elongated handle of a janitorial tool over the sink. A method of using a sink extender comprises mounting the sink extender comprising a sink that drains into a flexible hose and at least one tool holder to a support surface; running the hose to a traditional sink such that water may drain from the sink to the traditional sink by gravity; securing a wet tool to the at least one tool holder such that the tool drains into the sink.
