Can a traditional or CTI corner support a corner sink?
While we do not recommend cutting through miters or areas where seams are bolted together for a sink, it is possible if the area below the miters is completely solid with 3/4″ material. Cut the ¾” particleboard or plywood to fit the shape of the diagonal front extending 48″ from each corner. Attach the material with waterproof wood glue, secure with 1¼” wood screws to hold in place until the glue has dried. After all pieces have dried then cut the sinkhole in the proper place.
