I need some guidance. We have been in our home almost 3 years. We bought it as a spec home in a custom community. We of course have already had our 1 year walk through where the builder fixed the things we pointed out (or didn't). Now in my daughters bath there are a couple things going on that are of concern. First the tub is a porcelein tub. The finish is wearing/peeling off in areas. Instead of the glossy white finish there are large areas of dull white where it looks like the porcelein finish has worn off. The second is on the tiled wall surrounding the tub. This wall has 12x12 porcelein tiles with a decorative border. The decorative border has a tile pattern done in browns and blacks. These are tiles shaped in triangles. A couple weeks back when cleaning her shower in one area of this border I noticed what looked like dried blood. I tried to clean it off with out the stain budging one bit. I walked away from it and didn't give it anymore thought until this past weekend when cleaning it I noticed the stain looked a little bit bigger. This time I used a bleach based cleaning solution on it and still it did not come off. Now I am wondering if it is rust. If it is rust why would it be appearing in the center of the shower wall from behind porcelein tiles three years after the home was built. If it is a nail pop coming through and rusting I would imagine this means there is a leak and the green board wasn't installed properly. In any case I think a tub should last more than three years unless it is defective and whatever is up with the wall is concern too. I am hesitant to call the builder because I don't think they will do anything about it (this economy has really put a huge dent in their business from what I have heard) but I do know that the one year "warranty" is really by mouth only. By law I have heard it is 10 years. Before I give anyone a call I need to get some ideas on what this is and how to handle it. Thanks!
