My tile backsplash was installed after the OTR MW was installed, so there's no backsplash behind the MW. Read the installation instructions carefully with the new one, some of them have to be installed higher than your old one, especially if you have a pro style stove or cooktop.

That is a very good question. The panels would not be in front of the microwave at all, but right next to it, but still... it would be very challenging to remove the microwave. Thank you for pointing this out to me. :o)

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.

Go up to the upper cabinets and install the micro after. You may replace the micro with a smaller one, or even a vent hood down the road. It isnt very much more space to tile.
