the toilet facing (L/H side of A/C) the emer exit is the belted one. is or at least used to be an option. the standard toilet is on the R/H side, without a belt.
Then you can choose from either the standard (basically a bucket) and the flushing toilet (like a campapotti, just with a electric pump)
Divided by a curtain, not a door from the cabin (cause of the emer exit)
