Cover It Completely
Opt for a super large rug that stretches from wall to wall to cover up the concrete floors entirely. Keep it in the same color range as the concrete floor so it blends in and further disguises it.
As seen in this Wabi Sabi-esque space designed by Arent & Pyke, it’s just as effective and stylish, but it won’t be as much as an overhaul as replacing the floors would be. And it can even make a room-sized rug pop even more.
