My mother-in-law is redoing her kitchen. The current floors are linoleum. She wants to replace the floor with ceramic tile. She will also being replacing appliances and countertops (granite). The current counters are Formica. The floor installer raised a concern about tiling around the dishwasher and locking it in. There is no clearance between the dw and current counter. Has any faced this? I suggested having the counters replaced first since the older Formica counters are thicker and the granite might provide more clearance. Please suggest.
