When considering a guest bathroom and how to finish it, think of ease and efficiency as well as creating a haven for your weary traveler.  Ask yourself: Is everything at their fingertips?  Is it clear where items they may need are stored?  Would I feel welcome in a bathroom like this?  Open bottoms, or glass doors on a vanity is a great way to store items to have on hand for guests so they may see them clearly.  Have fun with the spa look; purchase large baskets to house things like extra tissue paper rolls, towels, or extra soap. The top on the Hutton Washstand by Restoration Hardware is 1 ¼” thick white Italian Carrara marble, but is available in other colors.  So when it comes to your guests, go ahead and spoil them, they just may not want to leave.
