Does the toilet brush holder have a drain hole or vent?

Some toilet brush holders have drainage holes or ventilation openings, while others do not.
A toilet brush holder with drainage holes can allow residual water droplets on the brush head to be discharged in a timely manner, avoiding the growth of bacteria and odor caused by accumulated water. Drainage holes are usually designed at the bottom or side to effectively drain water to the appropriate location and keep the interior of the brush holder dry.
Toilet brush holders with ventilation openings can promote air circulation, accelerate the drying speed of brush heads, and reduce the possibility of bacterial growth. Ventilation openings are generally distributed around or on the sides of the brush holder, allowing air to freely enter and exit, keeping the air inside the brush holder fresh.
However, there are also some toilet brush holders without drainage holes and ventilation openings. These brush holders may be designed with a focus on aesthetics or simplicity, but during use, it may be necessary to pay more attention to keeping the brush heads dry and clean to prevent the growth of bacteria and the production of odors.
When choosing a toilet brush holder, you can decide whether a style with drainage or ventilation holes is needed based on your own needs and preferences. If hygiene and dryness are important, then choosing a toilet brush holder with drainage and ventilation holes would be more suitable.
