Oh crap! You've just given me something new to worry about! :>) I have my OTR MW lining up perfectly with the bottom of my cupboards, and have had it templated for granite to end there too! I am assuming/hoping that it will be possible to find the same sized MW when we (naively hoping IF)need to replace it! Guess I could add some gorgeous little trim if it was smaller!

THanks for your replies. I guess we'll just tile up to it and keep extra tile in case we ever do away with the OTR microwave. Thing is, it is an inch lower than the cabs. So we'd have to cut tile or put a 1-inch border on the top of the tile everywhere else but there. The cabs are exactly 18" from the top of the counter, and I am using 3X6 subway tiles. So actually I'm going to have to cut some tile anyway to fit, because I have to allow for the spacing there will be between tiles for the grout. Therefore every piece (either on top or bottom) will have to be cut some. which leads me to another question - do you start the tile at the bottom or top? I'm thinking the bottom, the cut to fit right under the cabs? My head is starting to hurt.

If the added 1/2-inch doesn't make that "stick-out" difference bother you, go for it. But don't forget you then will have to hook that metal plate on top of the tile surface (screwed through the tile and into at least one stud and mollybolted through tile and the wall in the other required other spots where there may not be studs). That U-shaped metal plate with groove at bottom edge supports MOST of the weight of the micro unit and is what keeps the unit in the "air". In other words the unit doesn't really "hang" from the bottom of the upper cabinet.

I like your attitude and advice, Jancy. I do love my choice of countertop (Silestone Cemento Suede), which I paired with natural cherry shaker cabinets (3" wide rails and stiles) with orb hardware. I was going for a simple, warm modern farmhouse look. The kitchen is around 7' x 12." Three straight sides, no corner cabinets: a pantry wall with fridge (approximately 7'), an island with sink (approximately 7'), and a wall with range and otr microwave in the middle (approximately 7'). So my range wall is of similar length as yours, Jancy (90'). That wall is the only one with a backsplash and like you, I didn't want to deal with grout. I also liked the simplicity of the full-height backsplash... and, as a bonus, I had the extra material available from the countertop slabs, so I only needed to pay a bit extra for installation. Also, another consideration is that the kitchen is part of a great room and is visible as soon as you walk in the door, so it felt as if the stone backsplash would give the cabinet more of the look of furniture. I definitely don't want tile (even though I said earlier that might be an option). I would consider a stainless steel plate with brushed finish because it feels as if that would tie the range and microwave together... as if they were all one unit. However, the wall may be too short and the stainless too industrial for the look I'm going for. I do know however that I will not be happy if the stone gets chipped if I have to replace the microwave. In answer to your question, prosource, I believe the microwave will be fairly level with the bottom of the cabinets. The opening is 18" high and the microwave is 17 1/2" high. Also, I don't want to get off subject, but at some point, Jance, I would be very interested in knowing if you used plug mold and, if so, what kind. Or did you put outlets in backsplash? All thoughts welcome.
