The one in the shower, you mean? Well, I haven't actually figured out what the rules say about this. In practice, it's risk-free to keep the old drain, but likely you should replace it if you want to do it by the book. I guess as soon as a waterproofing membrane is applied, the drain it connects to should be of a newer model. I'll call the Byggkeramikrådet for another matter tomorrow, and I'll take the opportunity to ask them about this too.
You're welcome. However, one can hardly blame ignorance if one makes a mistake and gets injured because of it. The same applies to the law; not knowing that something is prohibited is not an excuse.
I will report what they said when I get home tomorrow evening.

But, what can really happen? I understand if there are wooden beams, for example, that it can have unpleasant consequences if the waterproofing doesn't work. But when it's pure concrete? If concrete couldn't withstand water, there are many houses and roads that wouldn't be in good condition...
Since the only organic material I have in the basement is the sill in a partition wall, which is 6-7 meters away from the shower, it should be completely risk-free. The rest is concrete, woodlice, a little bit of blue concrete.
Back to the original question: Will it look odd if I break the tiles to keep the slope somewhat intact? Or should I aim for an insert of completely different tiles, like 10x10 locally where the slope is?

Any other suggestions on how to get around the problem? I was planning to lay those small mosaic tiles in the shower corner, so that's fine. But it's the washing machine drain that's causing problems. Additionally, the slope goes outward in the room, so it becomes very visible, no matter what I do...

I have now talked to the building ceramic council. They are adamant that as soon as you have a waterproof layer applied to a certain surface, it should be done according to all the rules. New drain, all seals as they should be, and so on. He refused to say whether he agreed with me that it would be risk-free to keep the old drain in a case like yours, which I understand. You simply have to choose whether you want to deviate from the rules. I wouldn't have done it, but I do work with this.
Thank you for your response jon_h! Of course, he can't say anything other than what he is paid to say. Over a cup of coffee, perhaps his real opinion would be different...
Then I like BKR's rules regarding floor drains and plastic mats, where they don't specify a method but a product, Aqua Tät. I wonder how many hundred percent more expensive that product became when the rule was released...
