In due course, I will be laying tiles on the concrete floor in the laundry room in the basement. Right now, I'm renovating the sauna...
At the floor drain by the washing machine, I have a slope towards the floor drain of about 1 m in length and 80 cm in width. The level difference is about 5 cm down to the drain. My wife naturally wants large tiles, I would guess 30x60. But I see the problem with the slope and laying such tiles. Is it possible to do???
Then I read somewhere on the forum that if the floor drain is earlier than 1990, it has to be replaced. Is that correct?

It is impossible without breaking the tiles into smaller parts. It always looks like a makeshift solution in my eyes, as if the tiles were not chosen according to the circumstances. And indeed they were not.
Yep, that's correct. The floor drain should be replaced to ensure the connection to the waterproofing is approved.

No, that's naturally true. But on a concrete slab, does the waterproofing layer have any real significance? If it does, then I understand the logic of replacing the drain to ensure it's sealed all the way. But if the waterproofing layer doesn't have any significance, is it then so important to replace the drain?
We ended up a bit off-topic, but what applies to waterproofing membranes on a concrete slab? The laundry room is a combined laundry/shower/sauna with two floor drains. One by the shower and one by the washing machine. I will lay approximately 25 m2 of tiles in total. Where do I apply the waterproofing membranes? Is it enough around the floor drains? What about the walls against the shower? One wall is built of hollow blocks and the other two consist of lightweight concrete (blå...). Do these also need waterproofing membranes?
The entire room, all walls and floors, should have a moisture barrier (the sauna is a separate room, so the walls there do not need a moisture barrier). This is assuming it's not a concrete slab with direct ground contact, as is often the case in, for example, basements. In that case, you normally only install a moisture barrier where water exposure occurs.
It is a basement slab. So, there needs to be a waterproof membrane nearest to the drains + walls in the shower (but I wonder how much waterproof membrane there is behind the tiles that are there today, from 1973...). It seems logical, considering that all other floors in the basement have internal Platon to allow it to breathe. If you start waterproofing too much, the moisture will creep somewhere else, right?
Yes, exactly. But is the drainage working as it should?
And by the way, you can safely skip waterproofing and replacing the floor drain if water spraying is not going to occur around the floor drain in the laundry room section. I missed that it was a basement when I read your first post, sorry about that. The posts I wrote earlier do not apply to basements. My bad.
