Many people tend to use the floor drains in the balcony and the bathroom interchangeably during the purchasing process. However, in fact, the design focuses of these two are different and they cannot be randomly swapped.
The bathroom is in a humid environment for a long time, and its core requirements are to prevent odors, mosquitoes, and backflow. Bathroom floor drains have an appropriate drainage flow rate and are equipped with anti-odor structures such as deep water seals and silicone cores; the panel gaps are fine, preventing hair and debris from entering the pipes and avoiding pipe blockages.
The floor drain in the balcony aims for quick drainage as its primary goal. The instantaneous water volume in the balcony is large, and most prefer large drainage holes and large diameters for design, resulting in faster drainage speed. Most floor drains in the balcony have simple anti-odor structures, and some outdoor balcony styles even do not have built-in anti-odor cores.
The bathroom must use bathroom-specific floor drains with reliable anti-odor devices; closed balconies can be paired with simple anti-odor floor drains; outdoor balconies should prefer large-flow models. Try not to install balcony floor drains in the bathroom , as the lack of long-term anti-odor function can easily cause unpleasant odors.
