The bathroom is an important part of home design that cannot be overlooked, and its design and construction quality directly relate to the overall quality of family life. What should you do if the bathroom drain is too high?
How to Remedy a High Bathroom Drain
1. Effects of a High Drain Grate
The drain is an essential drainage facility in the bathroom, and it should generally be slightly lower than the floor by about 1-2 cm. When the drain is higher than the floor, surrounding water cannot flow into it, leading to water accumulation and potentially causing slipping accidents. Additionally, the issue of drain height may affect the release of odors in the bathroom, preventing foul air from being discharged promptly and compromising the bathroom's environment.
2. In-Situ Concrete Modification Method
The first remedy is to use the in-situ concrete modification method. This method is mainly suitable for situations where tiles have already been laid, and the drain height makes it impossible for water to drain. The specific operation involves breaking the tiles around the drain, followed by pouring new concrete to level the drain with the floor or make it slightly lower than the floor. Then, new tiles can be laid for aesthetics, matching the overall decoration style. This method requires professional contractors and can significantly resolve the drain issue, although it may impact the existing floor decoration to some extent.
3. Drain Height Spacer Method
If the floor is tiled and the height difference between the floor and the drain is minimal, you may consider using drain height spacers for adjustment. This method is simple, quick, and economical, and it will not damage the existing tiles. You only need to install a spacer on the original drain and then install the drain cover, reducing the height difference between the floor and the drain. The specific operating steps need to be selected and installed according to the drain's model and height difference, typically requiring skilled technicians.
4. Drain Relocation Method
If the original drain location is unreasonable or the height difference is too large, you might consider the drain relocation method. This method involves first removing the existing drain and then installing a new drain in a more suitable location. This not only resolves the height issue but also optimizes the bathroom's drainage system. Generally, this method has a complex construction process, requires professionals, and may incur higher costs.
In summary:the remedies for a high bathroom drain include the in-situ concrete modification, the drain height spacer, and the drain relocation methods. Each method has its characteristics, and the best approach should be selected based on the actual situation. As the saying goes, the skill lies in not saying much; I hope these suggestions can help you successfully resolve the issue and bring convenience to your home life.
