The actual pan is not leveled, our concrete flooring was leveled, the pan looked like it had been tampered with, the legs were all different sizes and the pan rocked all over the place. My plumber fiddled with the item for 5 hours. At the end he added shims and loaded it with spray foam. We are hoping for the best outcome. As my renos are in the midst, I could not wait to receive a replacement like Wayfair offered. 
Also Wayfair offered a returned label, nice but the item is huge and I have no way of transporting it to a Fedex Location... all in all not the greatest experience
