I am trying to motivate myself for a bathroom overhaul. We have blue tub, sinks, and toilet from the 60's. Given the sheer weight of the tub I would rather leave it and refinish the thing but I have zero experience with the kits that are available so I don't know how good they are. Anybody use one to refinish a cast iron tub? New tubs aren't that expensive, but trying to haul a 400 pound beast out of the house does not sound like a good time. I have read a TON of reviews on every kind of tub from acrylic to steel and everything else and they are all over the map. I would like a one piece tub shower combo but there's no way to get it into the bathroom.
