Second renovation, now the kitchen sink is at the kitchen door, and the drain pipe is also under the

Personally, I think that the drain pipe between the kitchen is still not a sewer pipe in the bathroom, and the smell of the bathroom is easy to string into the kitchen.

Your sink drain is right in the cupboard, and it's not too difficult, and the kitchen is that big, even if the water pipe is as far away as it goes, and you can put the drain pipe in the back of the cabinet and close to the wall, so it doesn't take up too much space, you think about it.

There are several scenarios for this:

1. Penetrate the wall to the bathroom, bury the sewer pipe, and then connect it with the shower floor drain in a three-way connection, which may increase the height of the bathroom floor.

2. Penetrate the wall to the bathroom, and the sewer pipe is directly inserted into the bathroom shower floor drain, so that the sewer pipe is exposed outside, which affects the use of no aesthetics.

Based on the above, it is recommended to go inside the cupboard.

Do a good job of renovating the sewer pipe in advance before the cabinet design, and then let the cabinet designer handle it when doing the cabinet design.

Theoretically, the head and tail of the sewer pipe can be connected together, if it is not long enough, two or more can be connected together, it is recommended to use stainless steel sewer pipe, which is more durable. There is also a good anti-odor system.

If the drain pipe runs through the wall to the bathroom and shower, a floor drain will also damage the floor. The water pipe has to be buried under the bathroom tiles and connected to the floor drain now.
