The problem is that when tightening the waste fittings the two skins of

Make hole in outer skin bigger so the waste fitting only needs to

clamp on the inner skin. You might be able to get away with just a
couple of slots opposite each other to slip the fixing nut through
then drop the waste in.

certainly lateral...

If you fill the gap and you get a leak between the waste and inner
skin but not between the waste and outer sking the gap between the
skins will fill up with bath water... That'll be really ripe after a
few months years...

eh?? so waste water will abandon the easiest, gravity driven, low pressure way out (of down the waste pipe) & force it's way, against air pressure, into the void between two skins of the bath? yeah right! ha ha ha;)


I think you'd have a job ensuring a perfect seal all the way round
between the skins.

the compression of the waste will shurely lend a hand?
