Transform a bath from the ground up by installing a new floor . The small floorspace of most bathrooms makes this an affordable renovation, and new flooring options combine moisture resistance with the look of favorite finishes. Lumber Liquidators' line of Tranquility resilient flooring offers a great range of natural wood looks and textures made from a water-resistant, easy-to-clean vinyl material. In a peel-and-stick plank format, it's simple to install over existing flooring and backed by a 25-year warranty. If you're updating a powder room, other flooring options like natural hardwood are possibilities. But for a full bath, stick with materials that will stand up to everyday use and humidity—that means you’ll want to avoid wood or bamboo.
