As indicated by the name, baseboard trim is generally installed at the base of the walls inside the home. It is intended to act as a natural transition between the wall and floor, as well as cover the expansion gap joint between the wall and floor. This type of trim is an inexpensive option that is commonly used to finish room renovations in houses and condos. You can invest in decorative baseboard trim, but it usually has an unembellished appearance since it's often covered up by furniture.
