For any on or above grade room, solid wood is a perfect candidate. You’ll be able to choose the particular species of wood, the finish, and the stain color. Even more choices are available here if you have your floors finished on site, instead of purchasing prefinished wood.
Your choices in those areas will depend upon several things, including the level of traffic in the rooms you’re looking to have floored. Be sure to discuss this with your flooring professional.
Solid wood is an excellent choice if you’re looking for a long lifespan. It can be refinished several times, depending upon the thickness of the wood, and with each refinishing, your floor will be brought back to a like new look all over again.
