SOLID HARDWOOD FLOORS
As the name implies, solid hardwood flooring is one solid piece of wood sawn from a log.
The standard thickness is ¾", but there are also options 5/16" and ½" thick. Older homes often have even thicker boards—pre-1850 houses can have floors as thick as 11/8".
Hardwood floors are recommended for almost all the rooms of a house—living rooms, dining rooms, bedrooms, and hallways. They are often featured in kitchens, but be aware that moisture can cause warping over time. Use mats or throw rugs in areas where water might drip, such as by the sink, to maintain the floors.
Solid wood floors usually aren’t recommended for bathrooms because the high moisture level makes it hard to keep them in good condition, but with proper care, they can work here.
It’s best not to use hardwood floors in basements—the culprit, again, is moisture.
