<< Anyone know of a nontoxic concrete paint that I can use to coat the bath part? >> You are better to use an acid wash that is permanent otherwise the paint will chip and look awful in even one season. Acid wash changes the look and feel and color but isn't toxic as I recall. If I remember correctly you are located in LA. try Bramante/Crescent City Sculpture in Kenner (800 864-9031). Vincent Guidroz is one of God's gifted young artists. I know they can advise you. Vincent studied in Italy and his "David" is better than any reproduction I have ever seen. Email addy: Bramante@bellsouth.net. The father Tyrus is on vacation right now so talk to Vincent. Mary-Anne
