Thanks for your interest! Since the shower is curbless, the shower floor was built with a slope toward a drain within the shower space. The entire floor of the bathroom has a waterproof membrane underneath, in case water seeps out of the shower, as extra protection.

Thank you very much. I am hoping I can get my builder to try something like this.

He does a great job on the zero entry, this would add so much to that.

Thanks again
