Hi Eric, my boyfriend has one of those stone tile showers that are HUGE. Well, the drain is clogged; I was cleaning it and a chunk of stuff feel into the the pipe. We have tried everything to unclog this drain. We have used a snake, drano, liquid fire, baking soda and vinegar, and coat hanger. It is still clogged and you can't use the shower because of all of the water that stands. Is there anything else we can try or should we just break down and call a plumber?
