There are two main areas where a bathtub leak might occur: the faucet drip or the underlying pipes. Additional areas to watch are the grout, body of the tub and the drain. Depending on the nature of the leak, you have different repair options. However, signs of trouble remain constant for both types of leaks. Be on the lookout for curling vinyl flooring or loose tiles, peeling or flaking paint, worn-out wood finishing, water stains on the ceiling, mold on the wall or floor, or general pooling around the base of the tub. Spotting these tell tale signs early might be able to save your bathroom from bigger issues.
