Leaking Showers

Find the Cause Before Choosing the Fix

A water stain on the ceiling, a soft spot in the floor or damp drywall next to the shower is stressful — and it's tempting to reach for a quick fix. But a leaking shower doesn't always mean the entire shower has to be replaced, and a patch won't help if it doesn't address the real cause.

That's why Keystone starts by evaluating the shower to help identify the likely source of the leak. Once we understand what's happening, we'll explain your options and recommend an approach that solves the problem properly.

If the issue calls for specialized plumbing work, we coordinate the appropriate licensed specialty trades as part of the project.

Diagnosing the Leak

Where Shower Leaks Come From

Shower leaks generally come from one of three places. Each one calls for a different solution, so we look at the symptoms and the existing construction before recommending any work.

Water supply plumbing
Leaks in the supply lines or valve that feed the shower.
Drain plumbing
Problems with the drain assembly or drain piping beneath the shower.
Failed waterproofing
A shower pan or waterproofing system that is no longer keeping water where it belongs.

Our general recommendation

When the Shower Pan Needs to Be Replaced

When a shower pan's waterproofing has failed, Keystone generally recommends replacing and properly rebuilding the affected pan rather than attempting an unreliable temporary patch. Water that gets past failed waterproofing can keep damaging the structure underneath, even when the tile looks fine.

In many cases the shower pan and the affected lower portions of the shower can be rebuilt while other areas are preserved — whether that's appropriate depends on the existing waterproofing system, the tile and the overall shower construction.

When a More Limited Repair May Be Possible

Occasionally, a targeted repair is possible. It depends on the existing drain assembly, the drainage conditions, whether matching tile is available and how the shower was built.

Not every shower pan can be repaired, so we evaluate the existing conditions first and give you an honest recommendation about which approach makes sense for your shower.

Built to Keep Water Where It Belongs

Why Proper Waterproofing Matters

Tile and grout alone are not a waterproofing system. A properly constructed tiled shower relies on waterproofing beneath the finished surfaces to manage water and protect the surrounding structure.

When we rebuild a shower pan, we install compatible waterproofing membranes and drain components designed to work together, following the manufacturer's installation requirements — with careful attention to the pan, seams, corners and other areas where water intrusion can occur.

Every new shower pan we build undergoes a 24-hour flood test before tile installation, to verify the waterproofing is holding water properly.

Questions

Leaking Shower FAQ

How do I know why my shower is leaking?

Shower leaks can originate from several areas, including water supply lines, drain plumbing, or the shower's waterproofing system. At Keystone, we evaluate the problem to help identify the likely source before recommending repairs or replacement. Finding the cause is the first step toward a lasting solution.

Can a leaking shower pan be repaired, or does it need to be replaced?

It depends on what's causing the leak. If the shower pan's waterproofing system has failed, replacing and properly rebuilding the affected pan is generally the most reliable solution. Certain drainage problems may allow for a more limited repair, but we evaluate the existing conditions before recommending an approach.

Do I need to replace my entire shower if the shower pan is leaking?

Usually, no. When a shower pan is leaking, replacing the entire shower is not always necessary. In many cases, Keystone can rebuild the shower pan and affected lower portions of the shower while preserving the remaining areas.

Whether a partial rebuild is appropriate depends on how the existing shower was constructed, the waterproofing system, and the condition of the surrounding tile and materials.

We'll evaluate your shower, explain the findings, and recommend the appropriate repair or replacement before work begins.

Why is proper shower waterproofing so important?

Tile and grout alone are not a waterproofing system. A properly constructed tiled shower relies on waterproofing beneath the finished surfaces to manage water and protect the surrounding structure. When rebuilding a shower pan, Keystone uses compatible waterproofing materials, follows manufacturer requirements, and performs a 24-hour flood test on the completed new pan before tiling.

Can Keystone evaluate my leaking shower and provide an estimate?

Yes. We offer free initial in-home assessments for leaking showers. We'll discuss the symptoms, inspect accessible areas, and recommend appropriate next steps. If further testing or investigation is needed, we'll explain that before proceeding.
