So I have a recessed nook about 64" wide and 30" deep (it fits my washer and dryer side by side, plus a 6" narrow cabinet pull-out). I'm planning to have a (probably quartz) countertop installed.
I presume attaching some wood to the walls to serve as cleats is going to be needed. What is unclear to me is exactly how substantial those cleats need to be. Naturally, I'll do the thickest wood I can fit without causing fitment problems for the washer/dryer, but it's going to be tight enough that I'd like to know how skinny I can go with the cleats before I start running into problems.
Right now it looks like I have, at most, 3/4" of clearance on either side between the wall and each respective appliance. Can I do 1/2" thick cleats on the sides (maybe thicker against the back wall since I'd have the space)? Are the countertop guys going to show up and laugh at me, or does this sound viable?
