The Risks of DIY Leaking Shower RepairsÂ
Can You Repair a Leaking Shower Yourself?
Many homeowners enjoy tackling DIY projects around the house. Painting a room or replacing a tap washer can be rewarding, but repairing a leaking shower is very different.
​
What appears to be a simple grout problem is often a symptom of something else. It's also important to remember that in most cases, the leak originates within the shower itself—not the entire bathroom. While a leaking shower should never be ignored, it doesn't necessarily mean your whole bathroom requires major repairs or renovation. Attempting the wrong repair may not only fail to stop the leak but could make the damage worse.
​
Before reaching for a grout float or a tube of silicone, here are a few things worth knowing.
Not Every Leaking Shower Is Caused by Damaged Grout
Cracked or missing grout is often the first thing people notice, but it isn't always the reason water is escaping. A leaking shower may also be caused by:
​
-
Failed silicone joints
-
Movement within the shower structure
-
Loose or hollow tiles
-
Cracked tiles
-
Failed waterproofing
​
Replacing grout without identifying the actual cause may only disguise the problem while water continues to cause damage behind the tiles.
​
Take a look at the bathroom below. At first glance, the shower appears to be in reasonable condition. There are very few obvious signs of a major problem. However, after carefully removing a small section of tiles, significant water damage and rotting timber framing were discovered behind the wall.
​
This is a good reminder that what you can see on the surface isn't always what's happening underneath.
Epoxy Grout Is Not Like Regular Grout
One of the most common DIY mistakes is using epoxy grout without understanding how differently it behaves compared with traditional cement grout.
​
Epoxy grout:
​
-
Has a limited working time once mixed.
-
Bonds extremely well and becomes very difficult to remove once it begins to cure.
-
Requires the correct cleaning process while it is setting.
-
Can permanently leave a haze or residue on tiles if not cleaned correctly.
​
Although epoxy grout is an excellent product when installed properly, mistakes can be difficult—and sometimes impossible—to correct without significant additional work.

Simply Adding More Grout Rarely Solves the Problem
It can be tempting to fill visible cracks with fresh grout, but applying new grout over old or deteriorated grout rarely provides a long-term solution.
​
For new grout to bond correctly, the existing grout usually needs to be removed to an appropriate depth. Simply covering damaged grout often leaves the underlying issue unresolved and may trap moisture beneath the surface.
Silicone Is Just as Important
Silicone is one of the most important waterproofing components of a shower, yet it's often overlooked during DIY repairs.
​
Applying new silicone over old silicone is a common mistake. Existing silicone should always be completely removed before new silicone is installed. Any remaining residue can prevent proper adhesion, allowing water to penetrate the joint and shortening the life of the new seal.
DIY Repairs Can End Up Costing More
Many people attempt a DIY repair hoping to save money. Unfortunately, when the repair isn't successful, it often creates additional work before the shower can be repaired properly.
​
Incorrectly applied epoxy grout, damaged tiles or poorly installed silicone may all need to be removed before the correct repair can begin, increasing both the time and cost involved.
When Professional Repair Makes Sense
If a shower continues to leak, the cause is unclear, or previous DIY repairs haven't solved the problem, it may be time to consider professional repair.
​
Many leaking showers can be repaired without removing all the tiles, but every shower is different. The right repair depends on where the water is getting through, the condition of the grout and silicone, and whether there are other underlying issues.
