The AirBNB Customer Services representitive my complaint was escalated to has written to me below
-----------------------------------------------------------------------------------------------
Bathroom classifications:
0.5 bath = a bathroom that only includes a toilet OR a shower
1 bath = a bathroom that includes a toilet, and shower OR bath tub
Bathroom (which is shown as bath on the listing's page) does not necessarily need to have a bath tub. One full bathroom just needs to have a toilet and a facility where people can take a bath (so, this could be either a shower or a bath tub).
We are aware that this has caused a lot of confusion with both Airbnb guests and hosts, as we are a global marketplace which caters to all types of people (international or local). However, we appreciate you doing a good job in setting proper expectations to your guests by adding information about the bathroom set up on your listing's description.
This would likely serve as your weapon in rare situations of guest's inaccuracy complaints.

Note the americanism " One full bathroom just needs to have a toilet and a facility where people can take a bath " They use the word "bath" for washing, something almost unique to their culture, and something they need to address for their international marketplace as others have also noted now.
I didn't realise though as a relatively new host - 13 months - that 0.5 bathroom used to have a different meaning.
At least they finally acknowledged this to me - after a few email exchanges.
I do have the text in my listing "Note: Studio 21 has a shower not a bath" - but people often don't read the listing details, and they obviously don't look at all the pictures as we have about 4 showing the details of the bathroom... hopefully in time they will fix this.
- I had never heard of a 3/4 bathroom before today........ It would be nice if there was a full line of icons to tick in setup - like shower. bath, toilet, kitchen/kitchenette, that ran in a line across the page, or even just the word Bathroom followed by whichever icons were applicable.
But hey, apart from one guest who was a horse's you know, we have had great guests all through, and are safely in the 4.9 bracket and running over 90% occupancy, so can't complain. The GOOD thing about the AirBNB software is that it is easy to use, the calendar works well, they have addedd that "reservations" menu option so you get all the bookings in chronological order. So things are getting better over time.
