ᐅ Toilet height too high – should it be lowered or left as is?

Good morning,

I was convinced by my plumber and builder to have the toilets installed higher than the “standard” height. However, it seemed like this higher installation is now actually quite common.

Now, the screed layer in the upstairs bathroom was done incorrectly. Somehow, it ended up lower than planned. This only became apparent relatively late. We are already living in the house and quickly noticed that the toilet on the ground floor is fine (although it still feels odd since we’re not used to the height from our old rental apartment). But upstairs, the toilet is definitely too high. My wife can barely place her feet on the floor.

My builder mentioned there is a so-called “patch set” that can be used to raise the toilet even higher. He immediately called his regular plumber, who confirmed this and even said it’s better this way because it’s less prone to clogging. I didn’t quite understand this, but okay.

I then called the plumber I hired specifically for heating and sanitary work and explained the situation. At first, he acted like I was talking nonsense but said he would look into it. He contacted two manufacturers (Grohe and another one), but they said it wasn’t possible. He still wanted to check with Villeroy & Boch since my toilet and wall-hung frame are from that brand.

That was a week ago. Unfortunately, he’s somewhat unreliable.

Is there anyone here familiar with this or who has experienced a similar problem? Is this “patch set” actually a thing? Or are there other, possibly better solutions?

What height are we actually talking about? Is your wife just particularly short so that her feet don’t reach the floor, or can it really be imagined, somewhat exaggerated, that the toilet seat is about 90cm (35 inches) high?…

I would have it measured first before giving any advice here.
By the way, the cause is the screed, right?! What does the screed installer say about it?

Okay. As I said, the contractor said that it would be better for the drainage. That made me skeptical because, in my view, it’s actually the other way around. Raising it is better for drainage, but lowering it is not.

Regarding the height, I’ll measure it precisely later. No, my wife isn’t particularly short. Don’t hold me to it, but I think she’s about 1.73 meters (5 ft 8 in). I’m 1.81 meters (5 ft 11 in), and even for me, it’s somewhat uncomfortable.

Yes, the screed installer isn’t really helping us with this either. As I mentioned, we already live here. He can’t just pour another batch of screed on top.

Why is it only the toilet where the height is incorrect? If I imagine that there is too little screed, shouldn’t everything be too high?

Well, it doesn’t really stand out elsewhere. Whether the shower fitting is 3cm (1 inch) higher or not doesn’t really matter.
And the large vanity cabinet holding the two washbasins was installed only after the tiling was done. So, the measurements were taken from the finished floor.

@Mycraft Why do you think this can’t be done as described by @cschiko?

Because your concern is about a WC that is too high. These "installation kits," however, are designed precisely to raise the height of toilets.

It goes without saying that a higher toilet outlet is better for drainage. This is because the water (and other waste) gains greater velocity, resulting in better overall flow.
