Creating a fire-powered shower

A neighbor of mine was looking into building a wood-heated shower. Therefore, we need to bend a copper pipe into shape.

It would be quite a long spiral. How would we go about creating this kind of thing in the makerspace? Is this the right place to bend copper into a spiral and into a big loop?

I have seen the device we used to bend the sculpture - would that work on copper pipe? We can have a look, I think…

Let’ see how much we need, too. The picture above is a shower of 50-60cm in diameter and 1m of height to hold the fire in the middle.
