The answer to 'bathtub leaking water' is that a bathtub leak can have several common causes, including worn or damaged caulking, issues with the drain, and problems with the tub itself. Symptoms may include water pooling around the tub, dripping sounds, or water damage on the ceiling or floor below.
To troubleshoot a bathtub leak, first check the caulking around the tub and the drain. If the caulking is cracked or missing, it will need to be re-caulked. If the drain is the issue, you may be able to tighten or replace the drain stopper. However, if the tub itself is cracked or damaged, you'll likely need to call a professional plumber to assess the problem and determine if the tub needs to be repaired or replaced.
