[floor drain method]
Note: The following laying method is for the conventional square floor drain, and the score is personal subjective opinion, which is for reference only.

①Diagonal

The floor drain is placed in the middle of the floor tiles, cut into four pieces along the diagonal line, and the grooves are formed according to a certain inclination when paving.

②Edge interrupt type

The floor drain is located on the side of the wall, and the floor tiles near the wall are straight strips, which can be cut off, and the middle position is reserved for the floor drain.

③Dislocation type

It is suitable for square floor drains, and the floor tiles are dislocated to leave the floor drain position to ensure the integrity of the floor tiles.

④Cross type
The floor drain is located in the center of the cross line of the floor tile, and the four corners are aligned with the edge of the tile and extend to the surrounding direction. Suitable for square floor drains with natural slope.

⑤Brick-in-brick type
The method is complicated, but commonly used. With the floor drain as the center, a box is drawn on the edge of the floor drain, and a diagonal line is made from this place, and the slope is made when tiling.

⑥Unqualified

Many bricklayers steal work and do it more casually, resulting in poor water flow, which is very unsightly. No matter the slope, the water will not flow completely to the location of the floor drain.

⑦ Seriously unqualified

Dig a hole directly on the floor tile to install the floor drain, the same tile is on the same level, there is no way to form a groove to introduce water flow, and it cannot achieve a good drainage effect.
