What is the optimal size of the distance from the top surface of the floor tile to the center of the

The distance between the center of the toilet outlet refers to the distance between the center of the sewage outlet and the wall that should correspond to the toilet after installation. At present, the size provided on the market is generally CM and other specifications, and now some products are designed with 2 holes at the bottom, one of which is available (if necessary, the cover can be removed, and then the other one can be sealed).

My personal opinion: when decorating, you can first go to the bathroom to measure the distance from the center of the sewage outlet to the wall, and don't rush to buy it back. There are a lot of people and things during the decoration, and it is easy to be destroyed.

It's best to wait until the painter is finished before buying it back and installing it. In order to facilitate the temporary use of the decorators, you can go to the market to buy the cheapest toilet first, and if possible, simply ask for one to put on. If the size of the toilet you like is different from the distance between the bathroom at home, you can ask the plumber to make appropriate modifications to the sewage pipe first, but there is no way to do it after the tiles are done.
