Freestanding enclosed double skin bath

[DiYdiot]

All pipework ready to go... ...only one problem - how do I plumb the thing in.
As the bath is completely enclosed with pipework to presumably route between the the inner bath skin and the outer skin how do I make connections?
I can fix taps to bath first but then can not make plumbing connection or make plumbing connection first to 'lose' taps but then can not fix taps to bath.
Similar problem with waste!
Any help would be a help.
Thanks

1) Fit taps to bath
2) Fit tap conns to lengths of pipe long enough to allow supply pipework to be attached under the outer skin when bath is in situ
3) Screw tap cons and tails to taps
4) Place bath in situ
5) Connect tails to supply pipework
