Pipes under shower tray

[Fallout]

Hi I am doing a bathroom and without causing mayor destruction to the kitchen below. There is going to be water pipes, under a shower tray on legs so they won't really be accessible at all. Is this acceptable? of cause I'll be using soldered joints on the copper were I need to under the tray.

Why not temporary fit the tray, mark where the legs are and route the pipes at a more accessible position ? Failing this if you are confident in your soldering go for it, loads of pipes this way.

Thanks I'm confident in my soldering and the pipes will be tested before the tray is fitted.
