A Complete Guide to Floor Drains: 3-Bedroom, 2-Hall, 2-Bathroom Homes Explained

As we all know, floor drains are essential items that must be installed during home renovation, playing a significant role in drainage within the home. So, how many floor drains are needed for a three-bedroom, two-living room, and two-bathroom layout?

How many floor drains are needed for a three-bedroom, two-living room, and two-bathroom layout?

You will need three floor drains. Typically, the bathrooms require two floor drains—one in the wet area and one in the dry area, which is the space between the sink and the toilet. However, it is advisable not to exceed three drains, as managing waterproofing at multiple drain outlets can be challenging. Additionally, installing too many drains can complicate tile laying. Therefore, it is better to opt for odor-proof floor drains. Another applicable location for a floor drain is the balcony, which can address multiple drainage needs. The diameter of the floor drain opening should be controlled between 6-8mm, so it's crucial to pay attention to the dimensions when purchasing.

What type of floor drain is suitable for the bathroom?

1. Spring-type sealed floor drain

Spring-type floor drains are categorized into upper-spring and lower-spring types. The upper-spring type involves pressing the cover plate; when pressed, the plate rises, and pressing again resets it. The lower-spring type utilizes a spring to stretch the sealing gasket at the bottom of the sealing core to achieve a seal. However, springs are often made of boron steel, which can corrode over time and gradually lose elasticity.

2. Magnet-type self-sealing floor drain

Magnetic floor drains feature two magnetic sealed joints. The floor drain switch operates based on gravity and magnetism. With a smooth interior wall, it is less prone to clogging and allows for direct drainage, although magnetism can still attract various impurities.

3. Triple-proof floor drain

Triple-proof floor drains are becoming increasingly popular as odor-proof floor drains in home renovations. They can withstand the hydraulic and pneumatic pressure from the sewage system, featuring little balls that provide odor elimination, insect prevention, and overflow protection. However, when purchasing floor drains, it is recommended to choose branded products, as these typically boast superior quality and longer service life.
