Karen, to read your typo and then go straight to Thomas' post beginning "I hate to bend over" really sent me into a giggle fit. I guess I'm easily amused.
Thomas, I wish I had a way to put my dishwasher up too. I might ask my architect to consider that--but then what do you do with the space above?
All your arguments for and against are good cases. Thomas, I'm like you--I make tea in mine every day and LOVE it for that. The tea goes into the water and the whole cooks together, the nuker turns itself off and about 20 minutes after I put the pyrex carage in there, tea's ready to pour. It collapses what is otherwise three steps and makes a better pot to boot. Other than that I melt better and heat leftovers for my lunches. That's really all. And that's why the more out of the way, the better.
Bob, does your microwave have the typical door opening left to right? The Sharp model I saw a picture of isn't IN a drawer, it IS a drawer--the door pulls out toward you and brings the service shelf with it. This deals fairly effectively, Karen, with most of the arguments against low-mounting. My own limited use for the thing only adds to it. For someone who cooks in one routinely, though, I'd advise against it for all the reasons you name. You know what, I few years ago (back when we were remodelling the Huntington Beach house), I had one designer suggest a low mount of a conventional microwave which I nixed immediately. But what interested me at the time was that she said that people were starting to do that so that small children could use the microwave to make their own meals from prepackaged frozen foods. Can you imagine not only expecting a small child to fend for himself that way but also use a microwave? I was horrified. If you're not tall enough to reach it you're not old enough to use it. In an all adult-household like Bob's, though, not a concern.
