I love banquette seating! A great breakfast nook/family dining option that just looks good in any kitchen. Especially in its own little nook with lots of light, and lift-up seats to store kitchen/dining linens.
Pinned for the idea. Not sure how much I like the extension over the toilet. If were to do, vanity top should be one piece, with no cut line. Also: Consider how much the extra counter space would be needed.
