I am remodeling my master bath and one contractor thinks we "need" to put in a free standing air tub instead of replacing the deck tub. Just wondering if this is a fad or something we should invest in. They are beautiful but is it worth the price tag? will it be a drawback 10/15 years from now when we sell the house. I don't want to replace all the tile and then find out that the free standing tub is only a fad. thanks for your opinion.
