Tile Trim Bender

Hi everyone,
Merry Christmas and a happy new year to come

Have a little problem to solve on a platform for a bath to sit on that I have to tile.
One of the corners of the rectangular platform is rounded off and I need to trim round this and along the straight edges. I am well aware that you can get formable tile trims to go round curves but it seems that bending this by hand is a little tricky?

So wondering if any of you guys and/or gals have any experience of this and some tips or can someone point me in the right direction to hire the bending tool that I have found out you can get. I am based in Hampshire.

I know I can buy the tile trim bender but £288 to bend one tile trim seems a tad excessive

Thanks in Advance

Could you get a plastic trim to curve adequately by making incisions in the hidden part to allow for movement with no buckling?

nope. plastic is no good plus plastic trims are pretty pants when it comes to a good finish much prefer metal

Only thing I could think of is to put it inside a piece of copper and bend that if you have a way of doing that.

Yeah plastic does suck but it's malleable so that's why I suggested it. Maybe give someone like Genesis or Homelux a ring and see if they have any suggestions?
