Toilets are made of . Porcelain doesn't handle sudden, intense heat well. If the chemical reaction creates a hot spot in your toilet bowl or trap way, the porcelain can develop microscopic cracks. You might not see them at first, but over time, those cracks grow. Eventually, you’re looking at a hairline leak, a pool of water on your floor, or a toilet that literally splits in half. 3.
