I grew up in a construction family and have a degree in architectural design and construction management.So I'm sure it is easier for me to do these things. I didn't put marble in this bathroom, it's the kids bathroom. But I did change out the sink and toilet. I went to a pedestal sink because I like the clean lines and the fact that kids can't hide junk under them. I really hate clutter and mess. I did see the new toilet that is getting ready to hit the market. Mamma wants! I will say I don't know anybody who has had a truly positive experience with Thomas. They can be hot and cold, but they are always pushy. They called us and came by our house because they were in neighborhood. We finally had to tell them who our family was and please do not knock on our door anymore.
