What Causes Shower Leaking Through Ceiling?

Have you noticed shower leaking through ceiling? This kind of plumbing problem needs to be addressed to immediately.

Even if you are dealing with just a small damp spot, you need to investigate the matter. Preventing water damage to your home is vital for several reasons.

There are multiple symptoms indicating the same problem. You could have water dripping from the ceiling or water leaking when shower is on.  The ceiling may be damp without water drops pouring. Or you can just notice a dry water stain that has been there for months. In any of these cases, you can’t ignore what is going on.

Shower leaking through ceiling and how to fix it?


The core of the problem is simple: due to gravity, water will flow to the lowest point it can find. But when it comes to shower leaking through ceiling, there can be different scenarios leading to this problem:

  • Broken water pipe

In this case, the water dripping on the first floor comes from a pipe and not from the drain. The leak occurs when someone turns the shower on. You usually notice moisture and leaks soon after someone starts taking a shower. The damp spots can also be seen on the wall where the pipe is located.

  • Damaged shower tiles

We choose tiles for decorative purposes, but they are also needed to waterproof the shower area. Water can seep under the tiles if they are cracked or the grout lines are damaged. The water stain appears after someone has taken a shower and slowly expands as water continues to soak the ceiling.

  • Dripping faucets

A dripping faucet can be faultier than you expect and also leak inside the wall. In some cases, you need help from a licensed plumber to avoid water damage. If you are lucky, it’s just a gasket that you can replace yourself, without professional assistance.[1]

Dripping faucets also bring another negative consequence: higher water bills. Even if it’s just a drip, those water drops accumulate and can significantly increase your water consumption.

  • Imperfect joints

Are you the messy type of person when taking a shower? Spraying the entire bathroom while cleaning yourself is not a good idea. For instance, the joint where the shower and the flooring meet can be cracked, and water will seep into it. From there, it will be infiltrating into the floor and slowly causing water leaking through ceiling.

  • Clogged drains

One of the issues that come with clogged drains is that water can overflow and leak through the ceiling below. The drain can get clogged with hair, soap, and other debris.

Negative effects of water leaks


Many people ignore shower leaks if the damage is minimal. This is a bad idea, for the following reasons:

  • Water damage

Water damage builds up in time and can even cause a ceiling to collapse! It may sound like a crazy scenario, but such events do occur. This can happen when water damage is extensive and left untreated for years. You should be careful when buying houses with active water damage.[2]

Before that, you will have the unsightly view of water stains on your ceiling. Furthermore, if water drips to the floor, it will also damage your floor tiles, especially if they are wooden.

Water damage can decrease the value of your property and cause you to lose thousands of dollars. Relying on your home insurance to recover your financial loss? Read that policy carefully. Most times, the insurer will possibly not compensate you the full amount. When the damage happened gradually, insurance companies consider you have neglected your home and consciously allowed damage to occur. And we can’t blame them for thinking this way.

  • Costly renovations

Calculating the exact shower leaking through ceiling cost is difficult. What we can say for sure is that your wallet or bank account will suffer from it.

Just like with any kind of damage, prevention is better than cure. Eliminating the cause of water leaks in time is cheaper than allowing it to cause damage. All that water damage can lead to expensive renovations. You will need to repair more than one area: the shower floor, the ceiling, paintwork, possibly the tiles on the first floor, and so on.

Such renovations also come with extensive disruptions. A complete replacement project can involve removing the shower tray or enclosure and that can be a huge mess!

  • Development of mold

Fungi spores are everywhere and just wait for the right conditions to create mold. Even a tiny water leak can cause mold. Moisture and a warm climate in your home represent the perfect breeding ground for mold.  Fixing mold damage can cost you thousands of dollars, not to mention the impact it can have on your health.

How to avoid shower leaking through ceiling?


Ideally you should be able to avoid shower leaking through ceiling. Any kind of water damage comes with repair costs and you want to avoid that. Here is some simple advice to keep your shower floor and ceiling underneath completely dry:

  • Use shower curtains

Avoid water puddles on your bathroom floor by using shower curtains. Remember to keep the curtains inside the bathtub when taking a shower.

  • Check the condition of your shower area

Areas to look at include rubber seals, gaps between shower tray and floor, tile condition, and grout lines. Even if they are built with care and attention, these spots can deteriorate in time. They will eventually become places for water to seep into.

Your shower may have a removable access panel, located in the room behind the shower wall. Inspect it every once in a while, and see if everything is OK in there.

  • Maintain your plumbing systems

Given that shower leaks can also occur from broken or loose pipes, don’t neglect your plumbing either. Have a regular professional checkup and make sure there are no leaks from your faucets or pipes.

Methods for fixing a leaking shower


Has water damage already occurred and now you have a true waterfall in your living room or kitchen? The quicker you act, the better.

The first step of solving this problem is turning the main water line off. Even if it is unpleasant and causes inconveniences, this is necessary in order to prevent further leaks. Get a bucket as you may deal with some more water dripping from the ceiling. Next, consider the following solutions:

  • Diagnose the plumbing problem

If the problem is from your plumbing, you are dealing with one of the following two possibilities. If the damp spot alternately dries and reappears, the problem is probably in the drain line. If you are dealing with a constant wet spot, the problem comes from a pressurized water supply line.

  • Access the leaking spot

Cut out an access hole in the ceiling. Don’t worry about ruining your ceiling, as the place is already damaged from water. Cut into the ceiling drywall until your find the leaking connection and follow the drainpipe upwards. If you are lucky, the drainpipe connection is directly above and the damage to your ceiling will be minimal.

  • Fix the water supply leaks

This can be solved by tightening fittings, most times. However, there are also cases when you may have to replace an entire pipe or sections of it. Make sure you replace the pipe with the same type, configuration, and dimension. Most drainpipes are made from white PVC or black ABS. To be sure, you can take some of the old fittings to the hardware store for comparison.  Make sure you also purchase special glue and primer that is needed to attach new fittings.

  • Repair the shower floor

If you are not able to find any damaged pipe, the leak is most likely caused by cracks in the floor. Let the ceiling opening untouched and don’t use the shower until everything is completely dry. Remove any parts or areas that are damaged from water and replace them.

Fix the shower floor first and test it. Only close and repair the ceiling hole when you are 100% sure there is no water leaking anymore. This repair may be costly, but it’s necessary.[3]

The Verdict

Don’t give up on your upstairs shower just because you are dealing with shower leaking through ceiling. Having a functional bathroom on the second floor is great and can make your home more comfortable.

When you are dealing with leaks, the important thing is to take action in time to avoid extensive water damage. The sooner you fix the problem, the less money it will cost and less work will be needed.

Don’t be afraid to take the matter in your hands. The worst thing that can happen is not being able to solve the problem alone. You can always get help from a plumber or construction worker, depending on what the cause of the problem is.
