ᐅ Installing a laundry chute in the shower?

Hello everyone,
we are about to complete the bathroom on the top floor of our new build. The pipes have already been installed going upwards. We have a laundry chute in that room. We would also like to install a shower, which would need to be positioned in a way that the laundry chute is integrated into it. Do you have any ideas on how to make the chute waterproof? Is this even possible?

A drawing would help to better understand the situation.

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 laundry chute but then removed it (due to concerns about noise disturbance from the utility room). I can’t say that I miss it. Whether I carry the laundry basket down or throw the clothes down the chute, I still have to sort them downstairs anyway. 😉

Close it and wear classic laundry. I would not take the risk of moisture.

I like the laundry chute idea, but not in the shower. What does the bathroom layout look like?

What about the shaft? What material is the frame made of? Where is the showerhead located 2 m (6.5 ft) away?
