There are three main reasons for the shower spacing of 15cm
1. Easy to use
Generally speaking, the water pipes used in households use plastic pipes with stable performance, low cost and long life. Maintain a safe distance of 15cm between showers to avoid affecting daily use.
2. Conducive to maintenance
Plastic water pipes are easy to expand in high temperature environments, so it is generally not possible to put hot and cold water pipes together. Otherwise, the two water pipes will affect each other and will be in a state of expansion for a long time, and even the surface of the tiles will crack.
3. Easy to install
The distance between the cold and hot water ports of the mixing valve on the market is generally 15cm. Since many showers and faucets are connected by the mixing valve, the pipe spacing is required when placing the hot and cold water pipes, that is, it is controlled at 15cm, and the error cannot exceed 5mm. Otherwise it will affect the installation.
