1. The low walls or reinforcing ribs around the bathtub should have sufficient support, and the surrounding sand should be compacted;
2. Do not use bricks or other hard objects to support the bottom of the bathtub, so as not to damage the glaze during use;
3. The bottom of the bathtub and the surrounding corners should be in contact with the full force and average force;
4. Pay attention to the tight connection of the overflow pipe and the drain pipe;
5. When attaching tiles, leave a drainage access port. In order to look good, you can use glue to stick the tiles on the access openings, so that they cannot be seen from the outside, and the tiles can be removed during maintenance;
6. Install the water fittings before placing the bathtub, and do a 24-hour closed-water experiment to see if there is water leakage at each joint;
7. When placing the bathtub, pay attention that one end of the drain is slightly lower than the other end. The outer end should be slightly lower than the inner end;
8. The actual size of the bathtub may be incompletely different from the nominal size. When purchasing and installing it, measure it on the spot, and reserve normal tolerances for the installation;
9. It is best to have a slightly inverted s-shape for the sewer pipe to avoid back odor.
