Improve comfort, bathroom renovation difficulties are broken

Bathroom design plays a crucial role in both the comfort of your home and the consistency of your overall interior style. However, common issues like floor level differences, water leakage risks, and hard-to-clean corners often cause frustration for homeowners. Have these problems been resolved? Can you use individual materials in the bathroom just like in other areas? Read expert insights to find out.

Challenging Topics

Based on questions from online users, we have compiled some of the most common challenges and key projects encountered during bathroom renovations. Experts have provided targeted solutions to address these issues effectively.

Water Pipeline Considerations

When it comes to the water system in the bathroom, the initial layout is usually designed by professionals, but the final decision rests with the homeowner. Cui Tao, an engineering manager at the Beijing branch of Current Decoration, emphasizes that homeowners should think ahead. For example, while most people still use traditional toilets, the future may bring more smart toilet options. “Smart toilets require proper electrical outlets and water supply lines to be pre-installed,” he explains. If these are not planned in advance, retrofitting later can be very difficult and costly. Even if some homeowners believe they won’t renovate again soon, Cui Tao points out that the frequency of renovations is increasing. Planning ahead not only saves time but also reduces long-term expenses. Therefore, he recommends that homeowners consider potential future changes when planning their bathroom renovation.

Waterproofing Tips

Waterproofing is one of the top priorities in bathroom renovation. According to construction standards, the waterproof coating on walls should reach 1.8 meters high near the shower area, while other walls should be coated 25–30 cm above the ground. “Waterproofing acts like a plastic bag that keeps moisture inside,” says Cui Tao. Once a leak occurs, repairs can be time-consuming and expensive, requiring tile removal and reapplication of waterproof coatings. He advises that since waterproof coatings are relatively inexpensive, it's better to apply them as much as possible during construction to provide better protection in the long run.

Some homeowners want to apply waterproof coatings on the ceiling to prevent leaks from neighboring bathrooms, but Cui Tao warns that this method isn't reliable. “Even though there are water-repellent coatings on the back, it’s not a permanent solution.” He doesn’t recommend it.

Another important part of solving the “water problem” is the threshold stone. Cui Tao suggests that if the bathroom door leads into the hallway, it’s better to install floor tiles instead of a threshold stone. This prevents moisture from returning to the floor, which could cause warping. If the area outside the door is part of the bedroom or living room, experts recommend raising the bathroom floor slightly to reduce water damage risk.

Structural Challenges

Many older homes face structural issues in the bathroom, such as uneven floors, outdated cast iron pipes, and limited space. These problems are often due to the building’s original structure and are difficult to change. “If the property allows, the floor level difference can be adjusted,” Cui Tao says. However, old cast iron pipes are prone to clogging and leaks, especially if connected via black rubber hoses. Unless damaged, owners can request property management to replace the entire pipeline system.

Another common issue in small bathrooms is the lack of space for essential fixtures. Ni Jian, a designer at Light Boat Decoration Dongzhu Shangpin, advises that the first step is to plan the functional layout—how to arrange the toilet, sink, and shower area. If the space cannot be expanded, the direction of the toilet installation becomes crucial. Most toilets can be repositioned to optimize space. In small bathrooms, using glass or mirrors can create a sense of openness. For narrow, elongated bathrooms, horizontal tiling or vertical wall patterns can visually widen the space.

Material Choices

Want to personalize your bathroom? Experts agree that unique materials can be used, but they must be selected carefully for the bathroom environment.

Waterproof Gypsum Board Ceiling

While aluminum ceilings are commonly used for their moisture resistance, some homeowners prefer waterproof gypsum board for its aesthetic appeal. It offers smooth surfaces and can be shaped into complex designs. However, Ni Jian warns that if there’s a problem with the internal pipes, removing the ceiling for repairs can be destructive. This material is best suited for larger bathrooms.

Sauna Board

Originally used in saunas, sauna boards are durable and resistant to heat. They can be painted for waterproofing and offer a natural wood feel. However, they are prone to cracking in dry conditions, so regular maintenance is needed.

Waterproof Wallpaper

Waterproof wallpaper is a good option for adding personality to the bathroom. It works best in large spaces where moisture levels are lower. It should be placed in the "dry area" to avoid dampness and peeling.

Waterproof Coating

Instead of tiles, some choose to paint the ceiling and walls with waterproof coatings. While colorful and customizable, once stained, cleaning can be challenging. Unlike tiles, coatings have a shorter lifespan and may need to be repainted more frequently.

Tile Cutting for Personalization

Even with traditional tiles, you can achieve a unique look by cutting them into different sizes. This technique maintains a cohesive look while creating visual interest. Cut tiles can be used at the waistline or behind the toilet to define the shower area. This method is ideal for all-body bricks and should be done in the factory to avoid dust and damage.
