Toilet too high - lower it or leave it as is?

Good morning,

I was convinced by my plumber and my general contractor that the toilets would be installed higher than "normal." But it sounded like this higher installation has actually become normal by now. However, the screed layer guy made a mess in the upstairs bathroom. Somehow it is lower than planned. But this was only noticed relatively late. Now we already live in the house and quickly found out that the toilet on the ground floor is fine. (Still weird if you are not used to the height from the old rented apartment.) But upstairs the toilet is definitely too high. My wife can hardly get her feet on the floor.

Now my general contractor said there is a so-called "Pfuscherset" with which you can actually set the toilet higher. He immediately called his regular plumber and he confirmed this and even said it is better than the other way around. Because it is less prone to clogging. I didn't understand that at all but okay. Then I called my plumber, who I specially contracted for the heating-sanitary trade, and told him about it. At first, he acted as if I was talking nonsense. But he wanted to inquire. He has now called two manufacturers (Grohe and another one) but they apparently said that is not possible. Now he wanted to ask Villeroy and Boch. The toilet and the concealed cistern are also from that brand. That was a week ago. Unfortunately, he is a bit unreliable.

Is there anyone here who knows about this or has had a similar problem? Does it work with this Pfuscherset? Or are there other possibly better solutions?

Let it lower

There are such botch sets and they are suitable for compensating a "height offset." I mean, up to 25mm is doable. Whether it is suitable for your situation can only be determined on site, but basically it should be suitable for that. I believe it is mostly used to get higher, but it should also be usable the other way around. The only possible problem could be with the holes for the threaded rods, depending on where the toilet is mounted and how much space there is.

So the problems insofar as you might see them afterwards. The mounts are not always that far from the upper edge, but you just have to take a look at it. Otherwise, the botch set should be just the right thing.

If your toilet is too high, lowering it is not possible without major effort. The only thing that helps would be a pedestal. Or indeed, once everything is removed (tiles, etc.) and the concealed cistern frame is installed lower.

Yes, that's the plan. Only how is the question.

Why do you think it doesn't work as described by ?

I would like to "revise" my answer a bit; on the one hand, there is the already mentioned problem (possibly the threaded rods won't fit and you can see them). On the other hand, look at the adapter piece for the drain; it shifts upwards, so you would have an edge in the drain.

That might work, but it is really makeshift! So I think for raising it, the makeshift set is quite okay, but for lowering it, it is really makeshift with several disadvantages.
