Love this look! I was wondering if you could give me advice please... - I am replacing a built-in vanity with a furniture style vanity and the spacing with the toilet and vanity is tight, similar to this. What is the norm for situating the vanity? Do I leave a gap between the countertop and side wall? If so, how much? Or can I just put the the countertop right up against the side wall( which I would think would be easier for cleaning purposes. Thanks!
