Does the home improvement industry standard stipulate that the bathroom wall should not be opened with horizontal slots?

The transverse slot can be made in the load-bearing wall and shear wall below 0.5m..

According to the national regulations, the grooving depth on the concrete wall should be below 10CM and the width should be below 10cm. According to this rule, no one can change the dark line!

So it's generally like this: you can walk on the ground, you can walk on the top, you really don't walk on the wall, you can walk vertically and horizontally.

Because the indoor floor should be tiled or installed, the conduit can be buried below. The bathroom and kitchen have ceilings, so you can walk on them.

The reason why transverse slotting is not allowed is this: transverse slotting will destroy the ability of the wall to resist horizontal internal stress. In other words, shear walls will be abolished. ~ Oh ~ Let's just say ~ The wall of the house is like an apple. It's hard to break, but it can be cut with a knife or a nail ~ in one go!
