Thanks for the kind words, Moni. For all I share this tale: In my previous old house there was no first floor bathroom, and we had an aging parent living with us. We decided to use a closet in the kitchen for a half bath. Sure, it was out of the main food prep area, but it still bugged me that there was a windowless room in the kitchen with a toilet in it (oh, we also carved out space in there for a stack W&D and possibly the tiniest sink, EVER). When we put that house up for sale (we had finished the restoration and I was bored) about 95% of the potential buyers remarked negatively about the position of the bath in the kitchen. Our options, including time, were severely limited, but we could have thought just a little more carefully about how to enter the half-bath, and flipped the door to it so you enter from the foyer, which was where the back wall of the kitchen closet was. I guess we just didnt think about that. My message is this: rather than do it fast and use whats already there, think carefully about adding a bath in a kitchen. In our case if we had been less anxious to get it done we could have been better able to sell the house faster and for a higher price.

First, I would love to see the wall below the border painted in one of the medium tones in the border paper. It would help break up the height of the space a bit. I think the wall where you have the art would be better served by a collection of three shelves on which you could place some decorative things, perhaps lean a piece of art, etc. One lone piece of art on the big wall may not have enough texture and interest to really break up the flat feeling of the empty space. However, if you want to keep the framed piece, it needs to be lowered so that the center of the art is at eye level. Hanging the art high doesn't solve the high ceiling issue. A narrow vase in the corner where the banjo top meets the wall filled with some twigs and greenery would be nice, and would break up the expanse of mirror a bit. Pick an accent color like a blue or green for your towels, rug, etc..

A generic question about a 80K project with no diagrams, pictures, or anything is not likely to get any input. Other than you will never get any return on that expens. Powder rooms are expected to be small and losing space in a kitchen is an BIG negative.

The pebbles are fine; some lines mesh together better than others, so get multiple samples if the ones you're considering to view. Be sure to hire a qualified installer to ensure a good outcome.
