How to make a round corner?

[esseven]

In the picture, you can see what I mean. It's a thin gypsum wall that ends with a curve. How do I make the curve itself? I'm having trouble wording the question, but you'll probably understand if you look at the picture.

Also, how do I make the curve of the edge strip after the floor? Could it be a plastic strip?

I don't know about curved plaster, but with the strip you could do what boat builders do and steam it until it becomes soft?

 

[esseven]

Ok, yes maybe that's how they did it, but the rule behind must also be curved, maybe a cut-out piece.. well, if the curved wall itself is made of plaster I don't know, but the straight wall is. I guess it's some kind of plastic material, I don't know. If anyone knows how to do it, I'd be grateful. Material?

There are MDF boards that are grooved on the back. They can be bent into all sorts of shapes.

Gypsum boards can be bent. see link:

Can also be a masonitskiva.

There are steel stud tracks from Europrofil designed for building round walls. The plasterboard is just wet and bend. The same applies to the baseboard.

Ah, darn. I'm eager to make a convex round corner in my new bathroom but the radius should be no more than about 15-30cm. Just a bit unsure how though.

There is a wet room board that is bendable, for example here:

Well, that's great! That could actually work.

It says:

30 mm can be bent to an external diameter of 520 mm.
50 mm can be bent to an external diameter of 1060 mm.

That is, I interpret it as the smallest radius I can get is 520/2 = 260mm. It's perhaps a bit larger than I initially thought, but not entirely off.
