Baseless: The most minimal of the bunch is actually a baseless condition where a piece of Z-metal separates the drywall from the floor leaving a ¾” reveal –or shadow line as we like to call it. The application is only used in certain situations, typically industrial or commercial applications where there isn’t a lot of foot traffic. Used correctly, it can give that sparse Chelsea gallery look that puts focus on the things and people in the room rather than the room itself.
Flush Base: the 3-1/2” or 5-1/2” tall base trim is recessed so that it’s flush with the wall. While it takes a bit more work and care to install, the look is clean and unencumbered. It’s a museum quality finish that can be achieved cost-effectively.
1×1 Base: the low profile section covers the gap between the drywall and the floor and also provides a bumper for shoes, vacuum cleaners, etc. At hardwood applications we tend to match the base with the hardwood (in this case maple), at carpet applications we’ll paint the base trim something close to the carpet. The end goal is to achieve a subtle profile that doesn’t draw your attention to the base.
