We have very similar dimensions for our vanity in our main bath. I think I am going to go with an 18" wide tower, which should leave room for at least a 54" long vanity, which is a good size with a single sink. I would determine what you plan to store in the tower and mock up and measure if they will fit. Are you planning to have drawers or roll-outs? That will take up more space too. I have an 18" pantry in my kitchen next to a 44" beverage counter, it doesn't look too large. I think you will be much happier with the extra 3" in your tower than on the counter.

Just take a look at what height your taps are in your current finished bathrooms. The height is not something that has to be standard, as long as it is comfortable for you.

I was thinking of the hutch idea as well. Put a pantry height at the opposite end from the oven and use the space between like a hutch. If you're into wine you could make this a wine bar or coffee area. As I thought about my own kitchen I realized I designed it with a landing area next to the oven and we NEVER use it like that LOL. We always open the oven and carry the hot stuff over to next to the sink or set on the cooktop for some reason. I guess it's just the natural traffic flow of the kitchen. So now the section next to my wall ovens is the beverage area when we have gatherings. I also like the idea someone mentioned for a laptop or charging area. You could hide some outlets up under the upper cabinets or do a couple of those pop up electrical outlets. This post was edited by bocron on Wed, Feb 5, 14 at 13:02

I think the granite looks great: very classic and a big improvement over the tile! I'd definitely look into undercabinet lights. Before, the white counters reflected the ceiling light back up under the cabinets. The dark granite holds onto the light and makes the undercabinet areas a little cave-like. Lighting will make a big difference. I think the previous suggestions are excellent: painting the wall in the kitchen, along with finding some colorful accessories. I had a small galley kitchen similar to this one, and I was amazed at the difference a bright blue rag rug and a few blue dishtowels over the stove handle made.
