There is nothing more seemingly innocuous than a house leak. You’ve seen it, you’ve heard, and you’ve mostly felt it. You may have noticed it downstairs when someone is upstairs in the shower. There could be wet spots or water stains on the ceiling directly under your bathroom. 

For something seemingly small and mildly annoying, it’s surprising how much damage leaks can cause. From structural damage to your home to possible health risks to your family, a water leak is both expensive and dangerous if you don’t take care of it promptly. And so, the first step to solving the problem is to find the leak.

How to Determine the Source of the Leak

Before anything, find out where the leak is. It may seem easy, but it can be pretty tough to pinpoint the problem. 

But here are five places you can start:

  • Water Pipes – If you can find the pipes, try to see if there are broken or loose pipes. If you notice any damage or dripping water, you can assume you’ve found your leak.


  • Bathroom Tiles – Check your bathroom tiles. While they can be decorative, their primary function is to stop shower water from getting into the walls, under the floor, and other areas of the house. Loose and damaged tiling, old substrate (the surface the tile adheres to), and worn-out grout can cause water to leak into the rooms below your bathroom.


  • Shower Faucet – If your shower faucet continues to drip even after you turn it off, this can also be the source of your leak. It can seep into walls and cost you hundreds of gallons of water. Among other things, damaged O-rings, washers, or gaskets can cause a faulty shower faucet.


  • Drain – A clogged drain tends to overflow and cause leaks through the ceiling. Check for any hair, soap, and other debris that could be blocking the drain.


  • Leaking Drain Gasket – Over time, the rubber gasket under the shower drain can dry out, crack, and leak.


  • Drain Gasket – The rubber gasket under the drain does not last forever. Over time it can dry out, crack, and eventually lead to a leak. 

While these are just a few possible places you can check to find the source of your leak, it’s a good start. It’s not an easy task and will take some trial and error, but it will be worth it. You might find other signs of water damage in your search that mean your water fixtures require an upgrade.

How Plumbers Fix a Leaky Shower

If you happen to succeed in finding the source of your leak, you may have what it takes to repair some of them if it’s simple enough. 

Before starting on any repairs, make sure to turn off the water supply at the main shut-off valve. When that’s taken care of, you can begin with some repairs. If you find that the leak is near the faucet or in the walls, simply tightening the supply connector joints can solve the problem. Be careful not to over-tighten, or it can warp the rubber fittings and make things worse.

When it’s Time To Call the Pros

It will be best to call in a professional for the following repairs than risk doing it yourself. 

If the water has damaged the substrate behind your shower, you may need new substrate and or tiles. If you find holes in your grout, even a small one, this may need addressing. And for drain problems, if it’s a simple blockage, a plumber can run a snake through the drain to fix it.
