Vinyl plank flooring is an excellent alternative to engineered or laminate wood. The cost-effective product is usually less than $1.50 per square foot and simply requires a utility knife for installation. First, measure the surface of the bathroom floor, adding roughly 5 percent to account for waste. Next, pick up the product from your local home improvement store, keeping in mind what finishes are best in regard to the room's traffic. Medium gray tones are excellent for children's spaces used daily since the neutral color aids in hiding dust and flaws. To install the vinyl plank, cut each strip to size with a utility knife, then lay each plank side-by-side, cutting away excess.
