wall oven cabinet size question
Hello. I have a question and I hope I can explain this clearly. We are building a new house and are planning the kitchen. We are hoping to keep our existing cooktop and wall oven but here's the problem. Our wall oven is a 27" (24" opening) and if I ever had to replace it, I'd like a bigger one. Has anyone ever retrofit a wall oven cabinet so that a smaller oven will fit in it? I believe the 30" size would need about a 27 or 28" opening. The cabinets we're looking at have 2 wall oven cabinet sizes available and the brochure doesn't list the outside measurements but it does show the openings and they are about 24" and 27" (and you can cut out for a slightly bigger opening).
I don't mind having pieces of wood on the sides (my husband is pretty good at matching up things like this, plus I'm not really picky) but I wasn't sure if it was okay to do something like this as far as holding in the oven and such.
