Hi Dr. Fred, can you guide me to your article on not sealing marble shower pans?

I would like to forward information to a customer that’s stirring up big problems on a white Thassos shower pan.
She already had the general contractor and the tile contractor tear out the pan and do it again. With the same problem which is patchy, dark and light throughout the pan soon after the water is turned on for the first time.
Thank you!
