One of the most important decisions you need to make is which thickness do you want for your rubber floor. There’s more to it than this, but the typical rule of thumb is: the thicker the rubber, the more it will protect your subfloor. Ultra-thin rubber can hold up to bodyweight exercises, light dumbbells, and high-traffic areas. Medium thicknesses are great for commercial gyms, CrossFit, powerlifting, and Olympic lifting. Ultra-thick rubber tiles are typically used for playgrounds where you need premium shock absorbency and safety ratings. Here’s a quick breakdown of our most popular thicknesses: 8mm – Most popular for home gyms. 1/ 4” - Made for basic home gyms and exercise rooms. 3/8” – Most popular for commercial gyms and CrossFit. 1/2” – Ultra-thick commercial gym / CrossFit flooring. 3/4” Ultra-thick commercial gym / CrossFit flooring. 1” – Ultra-thick gym tiles that you can install over plush carpet or residential playground tiles.
