The healthiest choice for flooring and the longest lasting in solid wood flooring. Carpet is very comfortable, but it traps dirt and dust and is virtually impossible to get completely clean after a period of time. Solid wood floors can be refinished over and over to look and feel brand new, avoiding the need for expensive replacement every 10 to 20 years as would be the case with laminate or carpet. Tile is a good looking choice, but is hard on the body like walking on concrete. However, there is no better choice that tile for bathrooms.
