There isn't a shortage of do-it-yourself ideas for updating your flooring. Basically, anything could become a beautiful floor, from pennies and corks to bottle caps and Scrabble pieces. Each project requires a good glue, a layer of epoxy and a lot of patience.
If you aren't up for taking on the project yourself, there are plenty of updates a professional can do. You just need to know what to ask for. White-washed or gray tones are really trendy right now for wood flooring. While the colors are mostly available in laminate products, the option is available in solid wood, too. Tile that looks like wood is another idea that isn't necessarily new but growing in popularity.
The patterns in which flooring is laid can add the upgrade you're looking for. Herringbone, basket weave and chevron are just a few basic designs that can draw the eye of guests.
