At 180mm high, this is the largest Bullnose MDF size in this group and it makes a very different statement from a standard narrow trim. It’s particularly worth a look when you’re after tall skirting in a bigger room, hallway or interior with higher walls. The design itself hasn’t been made complicated to compensate for the size. You still get a straightforward rounded bullnose edge and an 18mm-thick board. That keeps the profile clean while letting the height do most of the visual work. Measure the room carefully before ordering, especially around doorways, cabinets and built-ins. With a 180mm board, those little clearances suddenly matter.
