The distance from the center of the toilet outlet in my bathroom to the wall has been tiled is 37cm

You can buy a toilet with a pit spacing of 35 cm, the general imported brand toilet pit spacing specification is 40 cm or cm, and the domestic brand specifications are more complete, you can buy a pit spacing of 35 cm, so that there is no problem when installing the tiles as long as the tiles are thicker. So you can consult a consumer salesperson when you buy.

Choose 300, you can match the hole below, otherwise it is easy to block.

Don't get too close, it's really hard to maintain, and whether you rely on the wall or not has nothing to do with whether the knot is strong or not.

Only 300CM hole spacing can be installed, and there is no 350CM hole spacing. It doesn't matter if it's sticking to the wall or not, it doesn't matter if it's repaired and sturdy and it's close to the wall.

How to measure the distance between the toilet pits.

I had to choose the 300 specification, which is rare in the market for 350 specifications.

This is the most difficult spacing number.

There are two main specifications of the toilet in the current market: one is 400 (note: the actual is 380).

The other is an eye relief of 300 (actually 280). There's also an eye relief of 350, which is just right for your size, but it's rare, which reduces your options.

In this way, if you choose an eye distance of 400, (the measured is 380), it is theoretically 10 different. But if your drain is 100 (which is usually the case), the outer diameter of the toilet drain is about 80 (the specification of the general domestic brand). This way there is a margin of 10, which means that if you are lucky, you can install it (but the flange on the side of the mouth should be the best).

But there are certain risks. (Because there is no margin at all).

If your sanitary space is not too small and there is no obstruction, choose a smaller one, and it is common for there to be a few centimeters of seams in the back.

This is a problem that should be considered when retrofitting hydropower and there may be an opportunity to adjust it.

If it's the center of the pit, it's 35.
