Vinyl flooring comes in a variety of thicknesses. You will find a selection of thicknesses from 2mm to 5mm vinyl plank flooring. All vinyl plank flooring is a great alternative for areas that are water prone, as vinyl plank flooring is waterproof. If you are looking for flooring to brighten up an area with minimal traffic, vinyl plank flooring with a thickness of 2mm will work great. For areas that have more traffic and lots of activity, you will want a thickness of at least 4mm. Make note of any appliances and doorways, as this may determine the amount of space you have to work with. Vinyl planks are easy to install and no glue is needed. Vinyl planks in any thickness make for a fantastic DIY weekend project.
