Should the dry-wet separation bathroom cabinet leave a floor drain at the entrance and exit opening?

If there is no dry-wet separation in the bathroom, there is generally no partition drainage. Usually, only 1-2 floor drain is provided to facilitate unified drainage. Floor drains can be located near the shower area and the washing machine area. These two places have the largest displacement. Setting a floor drain here can prevent water accumulation. It is usually set in the bathroom, not at the door, otherwise there will be water at the door.

If the bathroom is equipped with dry-wet separation, it will put the moisture area. At least two floor drains are required. There is a shower room and a bathroom cabinet near the toilet.

Many families will put the washing machine in the bathroom, and there will be a faucet in the mop pool at home, so three floor drains are needed. One is the ground drainage of shower room, the other is the drainage of washing machine, and the other is the drainage of mop pool.
