Why should there be louvers in the lower part of the kitchen and bathroom door, in order to meet the ventilation of the kitchen and bathroom, because the kitchen and bathroom space is small and humid, because the design adopts natural ventilation, so the lower part of the kitchen and bathroom door should be set with louvers, which is the reason.

The kitchen and bathroom are places with more water, which are more humid, and the shutter door plays a role in ventilation. Some can also be designed as lattice doors, depending on personal preference.

Kitchens and bathrooms are generally humid, and it is best to have air circulation, so this is also the reason for the need for louvers.

Because the kitchen and bathroom have water and are damp, they need to be ventilated frequently, so they are set up with louver shapes.

Air circulation, the bathroom should be at normal pressure or negative pressure to prevent odor from dissipating, and no shutters need the door to be 30 gaps from the ground.
