Arriving at neww BKK domestic to a bridge gate B2.
Walkng towards baggage claim
1 Toilet (men) with 2 'seat' boxes and 2 urinals in main cross area of pier A/B intersection
1 Toilet (men) with 4 'seat' boxes and 4 urinals in the main bagage retreival hall.
That's all for hundreds of passengers getting of domestic flights where there is mostky no time to visit the facilities in the plane due to the short flight time resulting in very very long queues at toilets upon arrival.

Departure is OK as each gate holding area has its own facilities
