We've got a beautiful 12x24 travertine from floor and decor outlets. This is a GREAT resource for flooring..check it out if you have flooring projects.
Now I've got to give props to my very handy parents (they do this for a living) that are up helping me with all this....laying tile, building walls, adding trim, cutting doors....ewww, so much work.
Here's a little advice if your planning a project like this....be prepared to be a little overwhelmed, know that your house WILL be dirty and dusty, plan to eat dinners cooked in a microwave, ALWAYS have a crowbar and hammer near by, your hands and back will be a little sore, and make LISTS!!!!
Can't wait for ya'll to see the finished project...I can't wait to see it too!
