How high should the toilet triangle be over there

When decorating the house, the pipes, the inlet pipe of the toilet, and the triangle valve are generally reserved at the bottom left of the toilet. Because most of the toilet manufacturers now design the toilet inlet valve on the left hand side facing the toilet. Of course, the space location of each room is different, and the plumber can also reserve the triangle valve on the right side of the toilet, which does not affect the installation and use of the toilet, but if it is reserved on the right, it may be necessary to use a longer water pipe, and that's it.

This is not a leak from the triangle valve, but the rubber mat of the hose behind the angle valve is broken, and the leather mat needs to be replaced to fix it.

Yes, all toilets are the same on the water supply fittings. Like the angle valve of the water inlet, the link waterline between the angle valve and the toilet bowl is the same, the diameter is DN15mm, and it is commonly called 4 points of valve and 4 points of pipe. Recommendations: >>>More

Generally, the toilet will give an angle valve + hose + flange ring. At least that's what I bought at home.

It is still a suspended inclined roof, but the slope should be smaller, using a combination of sauna board and gypsum board, similar ones have been done before, send a picture to show you.
