How can I build a microwave shelf above the stove?

I would buy one. Much safer.

Just FYI. I'm sure there is a minimum safe distance required between the range top and wood, probably 30" or more. You can't put just any microwave above a stove. It has to be one made to resist the heat. So you need an over the range microwave. They usually attach from the top so your shelf would have to be over it and you need 18" clearance between the microwave and the range top.

You really shouldn't. Need to buy a vented microwave made to go over stove.

oh ok, I won't put over the stove then. I just wanted some kind of unique type shelf to put microwave on. I will put it above a counter instead..

What part of it is “unique”?

The should have a 1.5” hole for the electrical cord to route through.

They should give enough clearance around the microwave to let it “breathe” and reduce condensate build-up.

If you want a fascia around the opening to look completely built in, then you’ll have to drill many vent holes or provide some way for it to “breathe” out the sides or the top.

Thank you all sooo much! I have decided to put it on a shelf away from the oven, I think it is safest after reading all these messages! Thank you all again!

Something to use an a unique shelf options:

Cheap & easy: faux barnwood shelf that’s Melamine finish & very stylish brackets.

Blingy & easy: mastic on to a plywood shelf 1” glass mosaic tiles and then grout them

Substantial looking & easy: wood glue & clamp together 2x4’s or 2x2’s for a butcher block top. Belt sand when dried & stain any color you want and then 2 full coats of Marine-grade polyurethane. Microwaves make steam, thus the water-proof poly.

In all cases, the brackets must be attached to the studs with 1.5” or longer screws. The brackets need to be rated for holding the weight of the shelving, the microwave & the food weight (3 lbs Max?). My guess for total weight is 20-30 lbs depending on what you do for a shelf.

If you want to use a granite top remnant, I’d look into building a box frame for the structure.
