I have an old Elger cast iron sink. It is severly damaged, the ceramic coating is missing in areas with rust setting in. The sink is undermounted in a granite countertop and the foot print is unable to be changed. Elger does not have this sink available from what research I have done. Any kind of replacement would be acceptable but once again the dimensions must match. 33" long by 22" wide with a smaller left bowl of 9 x 19 and the right bowl is 19 x 17. The smaller bowl is actually wider, thus finding a replacement is difficult. Any suggestions?
