Cork probably wouldn't be durable enough for free weights or crossfit

Study floor and cover with the big rubber mats used for horse stalls.

Sorry but Steve Grimes is incorrect. And Ms. Shively is suggesting a rubber product that is foul smelling and is not ranked for 'indoor' use.

Cork floating floor can be used. It is relatively cheap ($4 - $12/sf...depending on what you buy and the quality you choose to work with). As a cork flooring expert, I've helped put in floating cork (click together) AND glue-down cork tiles in home gyms AND professional gyms.

Cork can handle whatever you throw at it...it just depends on WHAT you want to throw at it. If you are doing power lifting with free weights (300+ pound clean and jerk???) then you want to work with 8mm glue down tiles = biggest baddest meanest most expensive cork floor on the market. Something like that will offer 150 YEARS of service...and counting.

If you want an elliptical trainer and a tread mill and a weight training station then work with a decent quality cork floating floor. That's all you need. The durability of the finish rides with the MANUFACTURER. Like every thing, not all cork floors are created equal. The big names have some big finishes with MASSIVE price tags. Those could be over kill for you...or it could be EXACTLY what you need.

Let us know a bit MORE about what you want in your gym, how big the floor space and if you want NOISE control as well. I'll keep an eye out for this thread to see if I can help narrow down your choices.

@SJ McCarthy, came across this thread. Looking at a new build home gym approx 140 sq ft. Will do Peloton, Treadmill, weights, and high impact activities like burpees, etc. What are the recommended brands?

Hi, did you end up using cork flooring for the gym? How did it turn out? Looking to do the same.

I had a professional gym company come in and install indoor rubber flooring in our home gym. I don’t throw weights down, but I’m not being careful with dumbbells either. I like it a lot. You just need to damp mop it (or swifter) every once in a while to clean. (This was right after the install so it’s sandy from the installers’ shoes, we wear indoor sneakers in here so it never gets like this). No smell either.
