Where to start

Before you start peering under the tub or poking around for water damage, look for these telltale signs of a leak:

  • Unexplained Water Puddles: If you find water pooling around the base of your tub after a bath or shower, it’s time to investigate.
  • Ceiling Stains or Damage: Water stains, sagging drywall, or peeling paint on the ceiling below your bathroom are classic signs of a leak.
  • Mold and Mildew Growth: Excess moisture creates the perfect breeding ground for mold; this is especially common under the tub or behind walls.
  • Rising Water Bills: A sudden spike in your water bill could indicate a hidden leak somewhere in your plumbing system.
  • Cracks in Grout or Caulk: Even small cracks in the grout or caulk around your tub can allow water to seep through.

Pinpointing the source of the leak

Once you suspect a leak, the next step is to locate its source. Here’s how:

  • TEST THE DRAIN: The drain is one of the most common culprits of bathtub leaks. Plug the drain and fill the tub with water (just a few inches will do). Mark the water level with a piece of tape or a marker. Wait 30 minutes and check the water level. If it’s dropped, the leak may be in the drain or the tub itself.
  • CHECK THE OVERFLOW DRAIN: The overflow drain is the circular opening on the tub’s side. It can leak if its gasket is worn out. To test this, fill the tub until the water reaches the overflow drain. Keep an eye on the area beneath the tub or check for water dripping below.
  • INSPECT FAUCET AND SHOWERHEAD: Leaky faucet handles or a dripping showerhead can sometimes appear as a bathtub leak. Look for water dripping even when the faucet is turned off. Water pooling around the faucet handles.
  • EXAMINE GROUT AND CAULK: Cracked or deteriorating grout and caulk can allow water to seep into the walls or floor. Visually inspect and even run your finger along the edges of the tub to check for gaps or loose seals.

Tips for managing bathtub leaks

While repairs are best left to a professional, here are some steps you can take to minimize damage and prepare for the plumber’s visit:

  • Shut Off the Water
  • Clean and Dry the Area
  • Use Temporary Seals (Waterproof tape or silicone sealant)
  • Avoid Using the Tub
