Yes Gert on the website it actually says it is a stand alone item but then somewhere else it also says it's an underbench I could have it free standing but then do I keep my microwave or what do I put in the hole?
Yvette I'd give Whirlpool a call direct if I were you. They'd also be able to tell you about the trim kit and required clearance if you were interested in that. There doesn't seem to be any info about the trim kit on their website, but I don't think there was when we ordered one either, so may just pay to call and ask for a microwave expert. Trim kits are unique to the microwave I think, and I do know the Whirlpool one we had was not just what you saw at the front, there was a lot behind it as well so that the microwave sits at the right height for air to flow out the top and bottom vents of the trim kit. Hope that makes sense.
