Hello Seri

S| This house has the bath running 'along' the joists, a crack
S| has developed in the back wall that the bath runs
S| against. Could the weight of the bath have caused this
S| crack? Should the bath be running 'across' the joists?

Not neccessarily. Unless the floor is especially weak, then you can
plonk the bath any old way round. Crack might be due to many things, a
bath that is empty and virtually weightless for 99% of its time isn't
going to be the most likely culprit.

S| This house was purchased from Wayne and Waynetta slob, they
S| purchased it from Waynes DIY bodger father.
S| This house needs rewiring.
S| This house needs new ceilings.
S| This house needs a new boiler.
S| This house needs some new radiators.
S| This house needs new windows.

Learn, and learn to enjoy, DIY and take solace that you're not the
first and won't be the last to get caught like this.
