Abstract: A leak protector tray preferably includes a modular tray assembly suitably sized and shaped for being removably positioned within a sink cabinet. Such a modular tray assembly includes Notably, each tray has alternating tongue and groove edges that are interlocked together via a coupling to provide a secure and water-tight connection between adjacent trays. In this manner, the interlocking edges allow a user to adjustably link a plurality of trays to accommodate various sized and shaped sink cabinets, while ensuring moisture/water do not seep through the interlocked edges.
