Your question sounds like it fits better under "Building Materials & Construction Techniques". What you have on the walls before the actual bathroom construction probably doesn't make much difference.
But presumably, you then build the bathroom in the same way as if you had concrete walls. The blocks should be a good idea from a tile perspective at least, to get a good wall that can withstand the weight.

I have plastered isoleca behind the tiles in my bathrooms. Very easy to work with, just build up, plaster, and then the wall is ready to start waterproofing and setting tiles, etc.
It also feels good that there's nothing in the wall that can mold. It's just stone and that yellow foam in the middle.

I am also considering using Leca Isoblock, but I want to use them to build a load-bearing (will have roof trusses against the wall + a glulam beam) exterior wall. Any comments regarding Leca Isoblock as a load-bearing exterior wall?
How difficult is it to build/work with these blocks? Is it completely impossible to build by myself (I haven't built before)?

They build entire houses with isoblocks, so it's clear that they can be used in load-bearing walls. Whether or not it will be difficult, I can't say because I don't know you. My sister wouldn't manage it, but she can hardly change a lightbulb either 
As mentioned, I have isoleca on the lower floor and then a whole upper floor on it. Isoleca takes load directly from above well but is not particularly good at lateral load. So don't dig it down but feel free to place something on top.
Then make sure that both shells on the side of the sandwich construction take the same load. I placed a sill on top.

To distribute the load, beam blocks are used, which are insulated and cast in. When looking at an entire house, the load from the floor structure is generally taken in the inner shell and the roof trusses in the outer.
If you are going to plaster, use Leca's own plaster mesh, otherwise there will be issues with the warranty. Also, read carefully about the reinforcement requirements; it's not just about stacking blocks.
And don't just read up, but have someone who knows it go through it for you. Unreinforced Leca is hopeless even over relatively short spans. Ask for help, and by help, I don't mean the guy at the building supply store, but a structural engineer.mycke_nu said:
