The kitchen and bathroom are slotted to the floor or the wall

Kitchen: The line pipe can go underground, because the line pipe is 16, and the water pipe is better slotted.

Bathroom: The line pipe is best slotted on the wall, the light line above can be covered with a suspended ceiling, the water pipe can go underground, if there is no crossing, there is no need to groove in the ground, and the water pipe should also minimize crossing. The waterproofing of the bathroom should be done well.

If the back of the bathroom is a bedroom, it is best to do waterproof treatment on both sides of the bedroom and bathroom walls.

It is better to walk on the ground

Because the ground is sufficiently insulated and waterproof compared to the wall, and the wall of the frame structure of the house can be changed, it will be very troublesome to change it later if you take the wall

In some places, the water goes to the top, and the electricity goes to the ground.

Our hydropower is on the ground, and in some places the water is on the top, look, in fact, as long as it is done, it is the same as walking, hydropower is the main event, we must do a good job, otherwise it will be troublesome in the later stage.

Take a look at the connection I sent, which is dedicated to hydropower transformation.

Open a vertical groove in the wall, the water pipe is not grooved on the ground, and the floor tiles can be pressed directly back to the wall, and the bathroom wires go to the top or the wall does not go to the ground.

Slotting will definitely destroy the waterproofing, it's the same everywhere, but the waterproofing has to be redone again, and it will be troublesome to leak downstairs.
