The IdealLav drain from Watco is the only lav drain to include a grid strainer and a stopper, reports the manufacturer. The removable grid strainer is installed with an O-ring and is easily replaceable without removing the drain. The replaceable grid keeps the drain looking great and prevents hair and jewelry from entering the drain. It also features an internal stopper that seats below the grid strainer and holds water overnight. Available in plastic or brass, the IdealLav fits standard sinks with overflows and is ideal for new installations or replacements.
