A bathroom shower may leak due to various reasons. Here are some common causes:
Damaged or Worn-out Grout and Caulking: Over time, the grout lines and caulking around the shower enclosure can deteriorate, crack, or shrink, leading to water leakage through gaps.
Loose or Faulty Shower Head or Faucet Connections: Poorly connected or faulty shower head and faucet fixtures can result in water seepage. Loose connections, worn-out seals, or damaged cartridges can cause leaks.
Failed Shower Pan or Drain: If the shower pan is not installed correctly or is damaged, it can allow water to seep through. Similarly, a faulty drain or drainpipe can lead to leaks if they are cracked, improperly sealed, or clogged.
Leaky Pipes or Plumbing Connections: Leaks can occur within the plumbing system behind the shower walls, such as leaking supply lines, valves, or pipe fittings. Corrosion, aging pipes, or poor installation can contribute to these leaks.
Improper Waterproofing: In some cases, inadequate waterproofing during construction or renovation can cause shower leaks. Without proper waterproof membranes or moisture barriers, water can penetrate the walls or floors, resulting in leaks.
