How small are crew cabins onboard cruise ships?

I often gets asked, how small are crew cabins onboard cruise ships?

Take a look at the photos below:

This was my cabin in Norwegian Sun.

As you can see, thats it. :) that white door is the entrance/exit door, the one that has a blue siding is a cabinet, the one beside it is the bathroom door. You have a small table and a tiny bed. If you are anywhere taller than 6 feet, good luck with you are your feet will be dangling at the end.

my bathroom

The shower area is separated by a shower curtain, hot/cold water is always available. the sink is standard size and the toilet works on a vacuum system. Do not throw anything in the toilet except for number 1 & 2, otherwise get ready to have a clogged toilet.

Here's a photo of my cabin onboard norwegian epic. It's bigger than the ones from n. sun. This one has a port hole. (window). The bathroom though is even smaller, at least the living area here is alot bigger though.
