How many floor drains are reasonable in a bathroom?

It is generally recommended to install two floor drains in a bathroom. One floor drain should be installed at the shower area for timely drainage after bathing. The other floor drain should be installed in the dry area, usually located between the toilet and the sink, because the floor next to the toilet is relatively lower. Installing a floor drain here can help prevent water accumulation.

How should the direction of the floor drain be set?

1. The floor drain should be placed further away from the bathroom door. The purpose of a floor drain is to drain water and prevent odors and insects. If it is too close to the entrance, it may not achieve these effects and could even impact the rest of the home.

2. Ensure that the area around the floor drain is spacious. This makes cleaning easier. Many homeowners think that a lower installation is unsightly and attempt to hide it with decorations, placing it in cramped spaces, such as behind the toilet.

What to consider when selecting bathroom floor drains?

There are three common types of floor drains on the market: spring sealed, magnetic sealed, and three-proof floor drains.

The first type can be divided into upper pop-up and lower spring types. The upper pop-up type has a cover that pops up when pressed down, and it resets when pressed again. The lower spring type seals using the stretched spring beneath the sealing pad; however, the springs are often made of boron steel, which can rust easily, affecting their elasticity.

The second type uses the magnetic force of two magnets to create a seal. It opens and closes using gravity and magnetism, and this type features a smooth inner wall that is not easily clogged, ensuring smooth drainage. However, magnets can attract various impurities.

Finally, the third type is the latest anti-odor floor drain. It uses water pressure and air pressure to lift a small ball, achieving anti-odor, anti-insect, and overflow prevention effects.

In summary：the above information provides insights into bathroom floor drains. From the article, we can see that typically three floor drains are installed in a bathroom to ensure effective drainage and not impact other areas. I hope this can help everyone.
