How to change the pit distance of the toilet at home is 600

There's no way, or you pretend to squat, you have to have a platform to change it.

Otherwise, you can complain, this is a mistake in design and construction.

You can only use a positioner, and that won't change much, so try it yourself.

There are toilets with a 580 hole pitch on the market.

The toilet drain is 40 cm away from the wall, which means that the toilet is installed vertically on the wall, if the parallel wall installation needs to be at least 50 cm, so you can change the installation direction of the toilet (of course, it will affect the layout of the entire bathroom), since the original design determined 60 cm from the wall, there must be a designer's consideration, you can go to the developer to see the bathroom layout of the model room, or look at the original design of the bathroom layout. It's really not good, I'd rather install the toilet farther away from the wall than use the toilet shifter, we have used the toilet shifter in the actual construction, and almost all of them have been clogged within two years, making people's heads big. So I advise you not to use a shifter.

There is a shifter at the wrong distance from the toilet pit, and you have to buy it in the building materials supermarket

Depending on the developer's specific ideas, if you can't solve this problem well, you have the right to ask the developer to renovate and renovate.
