If you want a wood floor I would recommend engineered plank flooring such as Pergo Xp or Pergo Outlast. These are new styles from Pergo, both are extremely durable and the Pergo Outlast is very moisture resistant. The layered construction of engineered woods makes them more stable than solid wood, resulting in much less expansion and contraction of the flooring than solid wood. This flooring works best with an environment of 30-60% relative indoor humidity.

Another option is Allure Luxury Plank Vinyl Flooring, this product is 100% moisture resistant and is available in a number of wood like finishes. Its easy to install and is one of the most durable types of flooring you can buy.
