Is there a rule you have to center the side mirror cabinet over the counter? Ok, I have an old opening for a side mirror and it was centered over the old counter 21.5" I have to do some demo on the wall cause it is 3/8 of an inch too narrow for new cabinet. Boo I know! So since I am getting into demo my question is do you think it is ok to center the new cabinet on the wall rather then center it over the counter whatever that measurement maybe. The side wall is 24.5".
