Stairs are the perfect way to get from one level of your house to another. They can be made out of many different materials, but solid wood treads with marble tile risers is a classic look that never gets old. When you choose wood, you have the option of choosing either unfinished or finished for your stairs. Unfinished means it will need to be sanded and stained before use. Finished means they come fully assembled and ready for use right away without any further work needed on them! The best part about using wood stair treads is that they are extremely durable so there`s no chance of them breaking down anytime soon!
