WHERE THE WATER PIPES JOINTS ARE MADE.
In a bathroom we never put the joints of the water pipes, neither on the walls nor under the floor. If we did, we could save a few meters of pipe, but a joint can cause problems with water leaks over time. That leak would cost to locate and repair. In addition, the damage that the breakdown would cause would be important since floor tiles or wall coverings would have to be replaced.
When we project the reform of a bathroom in Banus Builder we place the joints and bifurcations on the ceiling. And we send whole tubes without joints to bathroom faucets. We use a type of tube and connection system that causes very few problems, but in the event of a leak it would be very easy to locate and repair through the false ceiling.
