Why Do Frameless Shower Doors Leak?

People love to add frameless shower doors in their bathrooms because of their sleek design and customizable structure. Moreover, the smooth edges and uniform surface make their cleaning easy.

Why Do Frameless Shower Doors Leak? Frameless shower doors leak because of small holes in hinges, absence of backup curtains, incorrect installation, poor application of caulk, damaged seals or gaskets, poor inclination of the shower curb, broken glass doors, poor meeting of panels, bad hardware, and damaged sweeps.

Water leakage is a common problem in these types of stylish doors because of installation issues and damaged hardware that comes with them for their installation.

Causes Solutions
Small holes in hinges Replace corroded hardware with a new one
Absence of backup curtains Add water-resistant backup curtains
Poor application of caulk Reapply high-quality caulking material
Damaged seal or gaskets Reseal the glass panels
Issue with shower curb inclination Rise the shower pan to direct water flow into drains
Broken glass door Use cement sealant
Poor joining of glass panels Add door seals to fill gaps at joining points
Damaged sweeps Add new sweeps

Small holes in hinges

The glass panels of the frameless doors are held together with hinges to maintain their structural stability.

These do not contain the sturdier frame to hold them in their place and prevent their breaking and shattering.

The glass surfaces are drilled with a drilling machine to make holes to adjust hinges. However, the point of the hinges is not secured or sealed correctly to make them watertight.

You can see the water leakages through these opened holes of hinges. In addition, incorrect installation of hinges can also increase water seeping.

Hinges can also wear out over time because of rust attacks and limescale build-up on their surface. You can resolve the problem by replacing the hardware and installing new ones.

Check the size of the preexisting hardware and select the new one with the same material and size.

Absence of backup curtains

Many people do not add backup curtains inside the frameless shower doors because these can affect their aesthetic appearance and make them look bad.

In addition, people install these types because of their transparent and airy appearance.

The primary purpose of the curtains is to keep the water and splashes away from the glass surface and prevent the hinges.

The curtains reduce the risk of wear and tear on hinges and corrosion attacks by limiting water exposure.

You can resolve the issue by installing the backup curtains inside them to reduce the risk of leakages through panels and hinges.

In addition, I prefer to use water-resistant vinyl curtains because of their durable and waterproof fabric.

Poor application of caulk

The caulk is the silicone sealant to secure the floor and walls properly. The silicone caulks lose strength and adhesiveness due to consistent exposure to water and humidity.

Professionals often do not apply silicone caulking perfectly, and you can see seeping water from their edges. The water seeping from the edges can damage the wall and cause the paint to scrape off.

The issue comes from using low-quality caulking material that cannot properly seal the edges and corners. As a result, the water enters into the tiles of the surrounding areas and makes them loose.

Properly recaulk the edges to seal them properly and reduce water escaping.

In addition, it is necessary to use good quality caulking material that can last longer and provide greater strength to the thicker frame.

Damaged seal or gaskets

You can see water dripping in the surrounding shower areas because of the poor sealing of the glass panels. The frameless door glass panels are sealed with gaskets or plastic strips to prevent water leaking.

The seals become loose over time, coming off from the glass surface and leaving spaces between them. Moisture can easily come out from these gaps, affecting the surrounding floors and allowing molds to grow on them.

Seals can also lose their flexibility and adhesiveness from steam and warm water exposure.

However, you can seal the gaps by installing the new door seals and using a high-quality sealant for their better adherence to the glass surface.

Issue with shower curb inclination

People often do not hire a mechanic or expert for the installation of frameless shower doors.

These become leaky because of poor inclination of the shower curb. Sometimes these are straight and allow the water to flow on the surrounding floors and damage the tiles.

The issue also comes due to their misalignment and poor installation. The misalignment and incorrect attachment leave a gap between the glass panels.

It is necessary to inline the curbs or pan vertically to redirect the water flow in the shower drains. It is better to call a mechanic because their installation is tricky and needs knowledge and skills.

Broken glass door

People often complain about the water seeping from the bottom of the shower doors, but these are properly aligned, and all of their side panels are stable.

Moreover, the seeps are adequately aligned but cannot control water outflow in the surrounding areas.

The leakage comes due to broken parts on their lower side. The glass can break easily because it cannot withstand stress and temperature changes.

In addition, these can also break during their installation and manufacturing. The broken parts leave a small gap on the lower side which is difficult to inspect.

Inspecting the glass surface from every side when purchasing the new one is necessary to identify any cracked or broken parts.

You can use cement sealants to fill these gaps and then balance the surface by sanding it with sandpaper.

Poor joining of glass panels

These doors contain different glass panels connected using hinges. Therefore, the leakage at these meeting points is easy to inspect and visible.

You can see water dripping on the floor from the middle of the panels when you take a bath in the shower. The issue comes due to the poor sealing of these connecting points.

The small spaces where two panels meet each other cause water to escape. You can resolve the issue by filling the gaps using door seals.

The door seals can fasten them completely and fill the spaces between them. In addition, the installation of seals makes them waterproof, and water cannot escape through them.

Damaged sweeps

The door sweep is the polycarbonate and vinyl material strip present on the bottom side. The primary function of this strip is to keep the water and soap scum inside and prevent the rest of the bathroom floor.

The risks of leakage increase because of poor installation of sweeps and their wear and tear. You can see water seeping from the lower side of the doors because of the damaged sweeps.

Moreover, the issue also comes due to the misalignment of these structures. These cannot control the flow of water, and it ruins the other area of the floors.

These sweeps are not present on the bottom side, and you can see water directly coming into surrounding areas because of the absence of a barrier and poor sealing.

You can add the sweeps if these are not already present. Select their color, size, and durable material while purchasing new ones.
