General recs are for two lights placed on sides of mirror at the eye level. This way you will achieve best light for face without putting it in too much shadows. I would suggest getting lighted magnifying mirror for make up issues. Do you want clearly identify two sinks or you would rather see whole vanity as single unit? Light in the midlle might serve as statement of unity and two lights above 30" cabinets will accent double vanities IMO.

If you want to repaint, use an acrylic enamel. Sand the chipped edges, scuff the vanity lightly with 120-150 grit sand paper. Wipe the vanity with a mild detergent. Use a tack cloth to remove any dust. I've had good luck with foam brushes (they leave no brush marks) - apply two coats - watch for runs. It may be easier to remove the drawers and doors. That way you can lay the doors flat to paint them.

cangelmd- We are venting the Panasonic through the side of the house. It's probably around 3 feet long. We originally wanted to vent the heat towards the vanity and the vent towards the shower. However the floor joists didn't allow this so we are going to have to figure a work around. The cover doesn't allow you to angle the heat. Layout below, We decided on a corner bench and not a rectangle bench as outlined in the layout. Vanity is 72 and will stick out a bit but this was the only way to fit a double sink in the room. Also the bathroom used to be a porch before it was finished. Underneath is an open crawlspace so it was beneficial to get most of the plumbing on the only interior wall.

...simple base cabinet w/ shelf... Is there a reason you have one of these? I'm asking b/c in my experience these are one of the most useless cabinets. You have to get on your hands & knees to access things stored in there. In general, the most functional base cabinets are drawers and pullouts (tied, depending on what's being stored), then ones with roll out tray shelves (ROTS), and dead last, stationary shelves. Mixer Lift...Is it worth it? It depends. If you have plenty of storage for everything you plan to store in the kitchen (including what you store in your current kitchen plus anything that's stored elsewhere that you'd rather store in the kitchen), then it might be worth it. But, be sure you get a truly heavy duty lift... Some people use their mixers while still on the lift, but you're really not supposed to. The movement resulting from a mixer in action can be detrimental to the lift hardware over time. Also, if any flour, etc. "splashes" out of the bowl, it will go into the cabinet and onto the floor instead of onto the countertop. Trash cabinet...good placement. Wine rack...I'm not sure that's a good location for wine storage. With a refrigerator next to it, won't it get too warm to properly store wine? (Refrigerators vent heat.) Baking Supplies...I would rather store them in drawers, but it's up to you. Remember that ROTS usually have short sides. This means that if you're storing things on tiered racks on the ROTS, you may have issues with things falling off the racks and onto the floor b/c there's no wall to "catch" them as they fall. If it's a specialty insert, I'd be interested in seeing it. Could you link it here for us? Island seating...how deep is your overhang? The NKBA recommends a minimum of 15" of clear leg/knee overhang for counter-height seating. In your elevations it looks like 12" or less. I very strongly recommend you increase it to at least 15", even more if you have the room. If this were my kitchen, I would probably put a prep sink either in the island across from the range or in the corner to the left of the range. It would give my a nice Prep + Cooking Zone space for one person or several. If just me, everything I need would be close at hand. If more than one, both sinks could be used for prepping or one could be used for prepping while the other is being used for cleaning up. There would still be plenty of room on either side of the range, on the island, and on the perimeter counters for prepping & cooking.
