Which brand of toilet pit distance is 30 cm

Instead of aligning the back, just align the toilet drain hole with the drain pipe. My personal experience is to use the tile as the basic plane, and raise the sewage pipe two centimeters above the tile surface, so that the two centimeters just go deep into the toilet drain to form a perfect butt.

Now the toilet (toilet) is generally reserved for two holes, one hole is 30 cm away from the center, one is 40 cm from the center, and one of them is blocked when you use it, if your toilet drain center distance is 60 cm, then there is 20 cm behind the toilet from the wall. Unless the demand is large and you can find a manufacturer to customize, the market may be difficult to buy a 60 cm toilet.

It doesn't have to be that big, I guess you're talking about the size from the back wall, but it doesn't matter, there are some very avant-garde designs with such products, you just need to provide the size range and then supervise the installation quality of the bottom flange to basically ensure that there will be no leakage.

Use as big as you need, the good toilet has three pit openings, and the bad one has two.

The national standard for toilet drainage is 400 mm, and the tolerance is 0-30mm, that is, the minimum pit distance is allowed to be installed in the toilet bowl with a minimum pit distance of 370mm. >>>More
