It doesnt matter how far away from the bath they are , steam will be the issue , and yes if you start to get shorts ( arcs ) across the speaker terminals due to moisture it will damage the amp.
Believe it or not, if you put wired speakers into a bathroom you might have to tell the council and get them checked to make sure they are safe. They are covered by Part P of the building regulations, and if you put them too close to the bath/shower you might be commiting a criminal offence!
Yep, bathrooms are considered a 'special location' when it comes to wiring things up. Because you are immersed in water it is very much easier to get a nasty electric shock and special regulations apply. Even from the extra low voltages found in speaker cables, the building regulations apply if youfix the cables.No way???
The technical term is 'fishing' Sounds like you have a stud wall.how the hell can you get the wire up from in the gap between to 2 walls when you get in the loft.

As you can see from that picture, it's possible for you to be able to start at the top of the wall and lower your cable down, then 'fish' for it at the bottom of the wall where your hole is. Using a metal tape measure to capture the cable and pull it through is a good trick. Problem is, if the wall was built properly in the first place, you will have horizontal 'noggins' between the vertical timbers to add strength, and getting past those might be difficult. However, a fair few builders don't do things properly and there is a very good chance they bodged it and there are no noggins in there so you might have a free run. Only real way to find out is to drill a hole from the top through the headplate and see what's down there, making sure of course you measure up first. Twice.
Something like this is invaluable if you are running cable around, every home should have one
Cable Rod Tool Box Kit though you get longer and cheaper ones on Ebay.
Of course if making holes in the ceiling has been ruled out then it doesn't matter anyway, but don't let a hollow wall get in the way of your aspirations...
These are an alternative...
