- Q.What’s the
best way to attach a dishwasher to a granite
responds: When faced with a granite
countertop, the trick is to provide a wood base to
accept the 3/4-inch-long screws I typically use.
Most granite countertops have a 3/4-inch buildup on
the edge. When the buildup is not too wide I attach
a strip of 3/4-inch cabinet-grade plywood behind
this edge, using silicone as the adhesive.
When the buildup is too wide, I have no choice
but to drill small holes into the underside of the
granite. I then insert plastic anchors, secured
with epoxy, to accept the screws.
There’s another technique I came across
after tearing out a number of older kitchens: It
seems that many builders rely on their good friend
gravity and simply jack up the front legs of the
dishwasher as high as they can. The top is then
squeezed so tight against the stone counter that
the dishwasher can’t budge. Seems
feasible, but I use fasteners just in case. n
