Small Propellor Hire Boats Is It Required For A Airplane To Have A Bathroom?

Is it required for a airplane to have a bathroom? - small propellor hire boats

I remember a few years ago, my family and I had a short flight (maybe about 30 minutes) on a very small commercial aircraft ... Propeller that works .. the open cockpit! I do not know bathrooms are on this plan. Now that I Crohn's disease, who are constantly concerned about the location of the bathroom. I'm flying this weekend, possibly in a plane without a bathroom? Thanks
