Install laundry chute in shower?

Hello everyone,
we are about to finish our bathroom in the attic of our new building. The pipes have already been laid upwards. We have a laundry chute in that room. We would also like to install a shower, which, however, would have to be positioned so that the laundry chute is integrated there. Do you have any ideas on how to make the chute waterproof? Is that possible?

A drawing would help here to understand the situation more precisely.

Hello, attached is a photo. The laundry chute should be integrated into the shower.

Practically maybe with a rubber seal, but would you really like that? We also initially planned a chute, but then removed it again (because of fear of noise disturbance from the utility room). I can't say that I miss one. Whether I carry the laundry down in the basket or throw it down the chute - I have to sort it downstairs anyway. ;)

Close and wear classic underwear. I would not take the moisture risk.

I think a laundry chute is good. But not in the shower. What does the bathroom plan look like?

What does the shaft look like? What is the frame made of? Where is the shower head located 2 m away?
