What brand are you getting? Is there adjusting feet on it? You might find that you are just fine. If height is a concern after the countertops are in, I know that Maytag has a better reputation for fitting in better than any other brand, assuming you are concerned about 5-10 years out (I did see your comment about your hopes that it is the "new" owners problems then).

It's a GE. I believe it does have adjustment feet. I presume that the rear ones would be accessible somehow even after the unit has been slid in??

I know! Install hydrolics so that the thing can be lowered and raised on command. Maybe you can modify one of those penis pumps.

Damn, I'm brilliant. ;)

I woulden't presume it. Cheapo ones will just be screws with feet on them very (inaccessible) once your all installed with counter over top and built up floor covering the gap to the floor

Some very nice appliances have long screws that go to the rear and a gimble which changes the direction on the force to the rear feet so you can do it all from the front. You can put it in measure it and take it back out to level it off.

Good luck

Yeah! make it hop like a lowrider around the kitchen.

When they installed my new dishwasher, replacing the original-to-the-house-avocado-green one, the plumber/installer did have to do some extra stuff because the drain line in the new dishwasher was differently placed than the avocado green one. (Not that the color is important, but it does pretty accurately date the old dishwasher ;) )
