The distance from the center of the toilet drain pipe to the wall is 40 5 cm, and the distance from

The distance between the sewage center of the toilet bowl is generally 300mm, 400mm, 500mm, and 580mm. You can also install a 400mm toilet in this case, if you install a 300mm toilet there will be a gap in the back, but it is best to ask the salesperson or the installation master to give guidance.

Basically, after pasting the bricks, the hole spacing is about 22, then when you buy the toilet, you can choose the hole spacing in 20-25cm, if it really doesn't work, you have to ask the mud master to install a hole spacing shifter, but this will affect the flushing effect, so you should think clearly.

From the appearance, the work is good, clean and neat, and the pipe fittings are also standard, there is no problem.

If you want a PVC100 pipe below, you can use a siphon toilet, as long as the tiled pipe below has a slope, it will not be blocked, and if you choose a straight flush toilet, you need to do a P bend under it.

You should be asking about the hole spacing (gross distance), right? There is no fixed standard in our country at present, and it is mainly influenced by other countries. The United States is 305, because the American standard entered China earlier, so China has the most this standard; The Soviet Union was 401 (for the reason of inch conversion), and many engineers in China learned from the Soviet Union in the early years, so the old engineers (design institutes) also followed this standard; The European standard is generally 200-230, but in the past 30 years, Europe has generally used wall drainage, so this standard is rare in China; The wall row is divided into two kinds, one is the ordinary toilet wall row, the required size is to complete the ground to the center of the sewage pipe 180, and the other is the wall-mounted type (now the mainstream way in Europe) Its size is 230
