ELI5: Why are most or even all toilets made of ceramic material?

Is their any benefit or its just a common style?

Mainly it is a better material for sanitation and durability versus the cost of production and ease of manufacture.

The alternative of say stainless steel like airplanes or prisons use would be overkill for but make sense when you don't want the weight of ceramic or don't want easily broken parts.

Plastics could work but using ones that don't scratch if cleaned would drive up the costs too.

Glass would be costly to mold and not provide a benefit versus ceramic.

Then possibly a artificial stone like solid surface countertops and sinks might work, but molding the shapes of the bend so it flushes and fills might be more expensive too and not provide a benefit either.

Having a material that doesn't rust or corrode and is easy to clean works pretty well in a bathroom.
