Consequences of Having No Drains in Bathroom Dry Areas

When renovating a bathroom, many homeowners opt for wet and dry separation, often installing floor drains in the wet area. However, opinions vary on whether a floor drain is necessary in the dry area. Below, I will briefly introduce the potential consequences of not installing a floor drain in the dry area of the bathroom.

Consequences of Having No Drains in Bathroom Dry Areas

1. Without a floor drain in the dry area, the bathroom may become quite humid, and the floor will not dry as quickly. After implementing wet and dry separation, the washbasin and toilet usually have designated drainage outlets, so there typically won't be much water in the dry area. Therefore, not installing a floor drain in the dry area may not have a significant impact.

2. If you decide not to install a floor drain in the dry area but still want good drainage capability, you can make the slope of the dry area slightly higher than that of the wet area during the bathroom renovation. You can also create a drainage hole in the water barrier at the dry-wet boundary, ensuring that the barrier is not too close to the floor drain. Additionally, construct a water guide channel around the floor drain to facilitate smoother drainage.

3. When renovating the bathroom, it's essential to ensure proper waterproofing. It’s crucial to follow construction requirements for waterproofing, such as applying waterproof coatings twice, and ensuring that the waterproof coating on the shower area walls reaches a height of 1.8 meters. Pay special attention to waterproofing at the junctions of walls and pipes, as these areas are typically weaker.

4. During bathroom renovations, the floor drain should be installed at the lowest point in the bathroom, with an appropriate slope for drainage. Choose a floor drain that prevents odors from the pipes from entering the room. Furthermore, ensure that the walls and floor are non-slip by using slip-resistant tiles. If the bathroom is small, you might opt for light-colored tiles to brighten the space.

In summary：I have briefly outlined the consequences of not having a floor drain in the dry area of the bathroom. I hope this article helps you gain a better understanding of the topic. If possible, it’s advisable to install a floor drain in the dry area to prevent water accumulation.
