   I am not sure what the question is.

   If you are talking about gas you still need a fuel and source of combustion air if you put it in an interior space.

   If you are talking about electric you just need large wires and space to put it and access for repair/replacement.

   What I am thinking of is mounting the Bosch PowerStar AE125 in the small bath, on the wall above the toilet.

   It is electric.

   The specs say it will handle the HW requirements for one shower maximum, which is the max we need.

   Is this done with these?

   Can be, that's a very european install, in some ways.

   Just do not forget you'll want hot water for the sink & washer, too.  (Don't ask me how I know.)

   The "magic" is in sizing by "fixture units."  And it sounds like you have a whopping 4. 

   Which likely means you can use one of the smaller units.  Which is good in gas or electric, as those services are what are usually large with the on-demand units.

   I am never installed one nor even seen the electric version.But I don't know why not.But they still require a safety relief valve so you need a place for that to discharge. And I really don't know the specs on those.See if you can download the installation info and see if there are any clearance specs and what is needed for the safety.But you should be able to make a "backless cabient" that would hang over it and hide it.

   As CapnMac mentioned, the heater-over-the-toilet is a typical European setup. I lived in Belgium for a couple years and grew to love these on-demand water heaters: very efficient, quiet, and an endless supply of hot water. Mind you, they can take North Americans by surprise. I remember when a friend of mine visited from the US. A few minutes after he entered the bathroom for the first time, I hear him shouting at me:"Hey, how do you flush this toilet? There's no lever!"A moment later, "What's this box on the wall over the toilet? Is that how you flush?"Clicking sounds as he presses a few of the water heater's buttons.A sigh of defeat, then "If I put a quarter in this thing, will it dispense perfume and condoms?"Pretty funny. Yeah, those foreign toilets can be hard to figure out at first.
