Effective Waterproofing Methods for Contemporary Shower Rooms

As living standards continue to rise, more households are opting to separate wet and dry areas in their bathrooms. However, many people report that even after renovations, water still seeps out from the shower area, or wall surfaces begin to peel after a few years. Despite the use of waterproofing measures during construction, the issue often lies in whether the waterproofing was done correctly.

So how can one ensure proper waterproofing in the shower room? Is the waterproof coating you’re using truly effective? Let’s explore some key tips to make your bathroom more resilient to moisture damage.

1. Use of Waterproof Coatings

When it comes to waterproof coatings, polyurethane is generally considered one of the most reliable options on the market. Avoid using low-cost alternatives that might compromise quality. If a bathroom begins to leak later, repairs can be costly and inconvenient.

The application process is just as critical as the product itself. Apply waterproof coatings during dry weather for optimal performance. Before starting, apply a primer and ensure the surface is smooth and even—any imperfections should be corrected in advance. Apply the waterproof coating in multiple layers, making sure to cover all corners and edges thoroughly. Apart from the floor, the lower section of the walls should also be treated, usually up to 30 cm in height, to prevent vertical moisture seepage.

2. Installing Water Retaining Strips

In addition to coatings, installing water barriers such as retaining strips can help keep water within the designated shower space. This is especially useful in larger bathrooms. These strips can be paired with glass panels or shower curtains depending on the design.

There are generally two types: plastic and stone. Plastic retaining strips typically work best when combined with glass enclosures, while stone types can be used with both glass and curtains. It's recommended to install the strip about 5 to 7 cm above the floor. After installation, always test to ensure it effectively blocks water. Take care when stepping into the shower area to avoid tripping on the strip.

3. Separate Shower Enclosure Considerations

If your bathroom features a fully enclosed shower unit, there are additional steps to ensure waterproofing. During installation, inspect the glass joints and base for any signs of leaks. It’s also advisable to block the floor drain temporarily and fill the area with a small amount of water for three hours to test for leakage. If any issues arise, they should be reported and addressed immediately to prevent long-term damage.

In conclusion, proper waterproofing involves more than just applying a coat of sealant. It requires attention to materials, installation techniques, and post-installation inspections. By following these tips, you can greatly improve the durability and hygiene of your shower room.
