All of the counters in our bus are at window height or even lower. I think that comes to 31 inches. Hubby & I had a go around regarding the island we bought at the ReStore, it was 36" high and I had a problem with it being that high even though that is standard.
I have very little upper arm strength and I have to depend on putting my whole body into doing certain things such as kneading & rolling out pizza dough and hand mixing. It was very hard having to raise my arms up so high.
I finally convinced him to lower it by jokingly telling him that if he wants to keep the island at 36" he can but he will be the one to do the cooking, especially frying chicken on our NuWave cooktop because I was not doing it. The cooktop raises the height even more and I didn't like having hot grease that close to my face.
Now that it's done, it has turned out to be the decision after all.
BTW: I think handicap counters are just a little higher than the windows in our bus, so we can just say we wanted everything at handicap level in case we needed it later down the road.
