Why is there no floor drain in the bathroom of a house in North America?

Because bathtubs are used in North America, there is no need for floor drains. I don't think there's any need to leak in the dry area, and there's an extra smell of it. Unless you like to clean with water! Usually there are water droplets, water splashes, just mop it with a mop Anyway, there will never be a water flow, and there is no water to enter the floor drain!

There is no floor drain is generally an independent room, because the foreign population is not so dense as ours, so there are not so many buildings, people's bath water can be directly discharged into the ground, do not have to cross the sewer like us, there is no floor drain in the bathroom in the United States, this is because the American bathroom uses a structure for the absorption of bricks, which is very different from our country, so the housing prices abroad are very high, but the purchase is affordable, enough for that price, is because there are a lot of small things to do very well, very popular.

Because it doesn't need to. Americans have a habit of walking barefoot around on the ground, so there should be no water on the floor of the toilet bathroom. There is a shower curtain to block the water from splashing out when you take a bath, and there is a carpet or bath towel to absorb the water on your feet after washing.

Why do you need floor drains? Floor drains increase the cost of construction (one more pipe) and are not hygienic. We are accustomed to leaking because we used to squat on the toilet and need to mop the floor and rinse it frequently+ our shower is generally not in the bathtub, so it is bound to splash.

People in North America, as far as I observe, there is no floor drain because it is not needed, the wooden floor of my bathroom, against the wall is the bathtub, the side of the bathtub is the shower curtain, the shower curtain has two layers, the inner layer is plastic sheet, put on the bathtub inside the test, the outer layer is cloth, put on the outside of the bathtub, the water can not splash out when bathing, the floor is kept dry for a long time, and there is no need for floor drain at all.

The product will penetrate into the base layer and make the base layer waterproof. The product is recommended to be constructed in a dry place, the drier the base surface, the deeper the product can penetrate, if the base surface is full of moisture, high density, the material can not penetrate well. Regarding the principle of waterproof plugging, the source of water leakage is not blocked, and the water will only continue to penetrate into the wall, which will exist inside the wall for a long time, and will leak out from other parts of the wall when the water reaches a certain level.

The problem cannot be solved, and only by spraying waterproofing agent on the outside of the roof or exterior wall so that the water cannot penetrate into the wall and flow away can the problem be completely solved.

Many houses in Japan also use the "falling plate" type of same-floor drainage, and there are some such real estate projects in Nanjing, such as the Chengkai Home on Shimenkan Street. This type of drainage on the same floor can use floor drains. The reason why many toilets in foreign countries do not use floor drains is that the drainage method is different from that in China, and floor drains cannot be set up.

It is not "intentionally not to install floor drains", nor is it related to "prevention of infectious diseases such as SARS".
