How could I rinse 50x60cm paper using these sinkspri

[bonk]

I need to print some larger prints from 4x5 negatives on 50x60cm paper. It will be RC paper for now but later I also want to try fiber at that size.

My sinks are only 52x50cm and look like in the image below.
How could I handle 50x60cm sheets using those sinks?
I guess it wouldn’t be a problem that the paper is slightly bent while rinsing but I need to find a way do constant add and drain water. I can’t come up with a good idea for that.

Drain pipe with an inner circumference of slightly more than 60 cm and a length slightly more than 50 cm, and some means of keping the pipe rotating in the sink.

I am not sure if I understand it right.
So the drain pipe would somehow stick in the outlet or be connected to it and the drain pipe would stand upward.
There would be no water in the sink but just inside the drain pipe together with the paper which would be rolled inside and the rolled paper would also „stand“ vertically ?
New water would constantly flow from the faucet into the pipe and constantly leave through the outlet?

I don't think I have ever put RC prints in a print washer. I always have washed them in a tray. Even fiberbased prints, after hypo-clear, can be washed in a tray too.

What is that gray thing hanging in the tray? Does it at new water and remove old water?
How do you wash the paper in the tray and for how long?

Maybe I should just get one of these?

DEVILLE Washer - for darkroom trays 30x40 cm and larger: https://www.fotoimpex.com/darkroom/deville-washer-for-darkroom-trays-30x40-cm-and-larger.html

Are they any good. Is it worth it?

I usually wash for 5 min for both RC and fiber base (after a 5 min hypo-clear for the fiber based) The Kodak tray siphon was a common item, I think other companies have copied it. I won't stir-up discussion if fixer goes to the bottom or is diffused throughout the water (PE covered that already).
One thing I did notice, I was looking at some RC paper from 1986 and it had some brown spots. I remember the project and I think if one is washing like 20 prints in a row, it might be a good idea to do a complete exchange of water occasionally. I believe the Kodak tray siphon can be overwhelmed if you run too many prints through in a given time.

No - that size of pipe will fit on its side in the tub.
Use the tub as a big, high sided tray.
The print goes into the pipe, against the pipe's inside, with emulsion facing in, and the pipe goes into the tub, and gets rolled back and forth between the edge and whatever you are using to make sure there is enough water in the tub, until the print has been washed,

That is a Kodak Tray Siphon, and it does.
The water moves around in the tray and washes the print. How long depends on whether the print is RC or fibre based. If RC, about 5 minutes should be fine, if it is clear that there is lots of well recirculated water.
If it is fibre based paper, it varies with the type of fixer, the weight of the paper, and whether a wash-aid is employed. Longer than 5 minutes though.

So that there is no confusion with my post #7 above; 5 minurtes of wash is all that is needed for fiber based paper.

The page actually quotes 2 x 5 minutes (= 10 minutes wash in total) with a 10 minute wash aid in between washes.

But even 10 minutes is still a lot less than some people quote in answers given to this type of question.
