HI, I am redoing my old bathroom and have no clue about this stuff! Thanks to reading the toilet board here, I made my first purchase for the remodel....a TOTO toilet! Now I must move on to a tub. I just need a regular 5', 30" tub, but am confused whether to get cast iron, acrylic, "americast", etc. HELP! I only want to spend around $300, if possible. I see Kohler has a Villager that is cast iron and in my price range, but I don't care for the "v" design on the outside of it. Is there any other manufacturer that has a cast iron in this price range? Or is there a better choice? Thanks for any info.
