What would be a better choice for a shower floor in a new bathroom? From what I can gather the price of materials for both is about the same. The torazzo material seems a lot more substantial. Another shower in the house has a torazzo floor which has performed well 40 plus years. The cultured marble also appears subtantial and represents the new technology. But it looks as if it could be scuffed or scratched. Any comments? Thanks.Robert C. Lang
