Should bathroom doormats be placed inside or outside the door?

It is recommended to place the bathroom doormat outside the door.

1. ‌Avoid moisture and bacteria breeding‌
The bathroom environment is humid, and the floor mat is easily damp when placed inside the door for a long time, becoming a hotbed for bacteria and mold, and even producing odor. Especially in bathrooms without dry and wet separation, the floor mat is more difficult to dry after absorbing water, and its functionality is lost.

2. ‌Anti-slip and safety‌
A damp floor mat may increase the risk of slipping, especially if the common nylon or polyester materials have poor anti-slip properties. If it must be placed inside the door, it is recommended to choose a rubber anti-slip floor mat, but be aware of its insufficient water absorption.

3. ‌Functional retention‌
The core function of the floor mat is to absorb moisture and dust from the soles of shoes. If placed inside the door, long-term moisture will cause it to be unable to absorb water effectively; if placed outside the door, it can remain dry and is more conducive to cleaning the soles.

4. ‌Space and convenience‌
‌Outside the door‌: It does not take up bathroom space to avoid getting stuck in the door gap when opening the door.
‌Inside the door‌: Although it can reduce dust in the living room, it needs to be cleaned frequently and is easy to get dirty.

5. ‌Material and maintenance recommendations‌
If you choose to place it outside the door, give priority to diatomaceous earth mats or easy-to-clean materials, and replace or disinfect them regularly (recommended every 2-3 months).

In summary, ‌Placing it outside the door is more scientific‌, taking into account hygiene, safety, and practicality.
