Due to questions from readers I'm aware many people in the USA and UK have a different idea of what is or isn't in a bathroom, and bed sizes. Here in Australia we have a number of arrangements for a bathroom, and different sized beds.
The link above has a good list of the various bed sizes. What's important is here in Australia we have King single which is 42 inches by 80 inches which I often mention.
A bathroom may contain a bath, a shower, a basin sink in a bench, a toilet, and space to dress - or any combination of them. Also, a bath may or may not have a shower over it. The simple rule is if any one of the above is shown as having its own room, then it's not in the bathroom. Thus the bathroom in Survivor: Moving On has a bath (in this case with a shower over it), a basin sink area, and space to dress. We also have a thing called a four way bathroom where there's a sort of central basin sink area with three doors off it to have the bath, toilet, and shower each in their own little area to allow privacy and multiple users. A three way bathroom is the same but no separate shower.
An en-suite is a cut down version with a sink, toilet, and shower or bath with a shower over it.
I hope this helps you to understand the plans I include as a memory aid.
