How to remodel the toilet drain into two

This is really difficult, because the sewer pipe layout of the toilet in your bathroom is generally at the top of the downstairs bathroom, if you want to change it can only be carried out opposite your bathroom, so that the floor of the bathroom will be raised, and the bathroom will be higher if there is floor heating, and there is also the problem of waterproof layer, if it is not done well, it is likely to leak the problem, so it is not recommended that you change.

If you want to change in your own home, you can build a platform to raise the bathroom floor, if you are a new house downstairs and can't hold back, you can directly connect the sewer pipe of 110 with rhinestones on the floor slab, and your bathroom does not need to be heightened, but the waterproof must be done well after drilling the hole, or you will be in trouble in the future.

Converted into two in the same room. I've never heard of it.

It's not the same room. It is necessary to base on the situation. It's not like you just want to change it.

The toilet in our house is the same, and later a friend taught me a way, which is to press the flush button a few more times, press a dozen or twenty times, and he will not flow.
