Anyone know were to purchase a wide shallow training pot?

I've looked around without any luck. Anyone know where I can get a wide shallow training pot? Something about two inches deep, twenty (or more) inches long and fifteen or more inches wide?

Something like this. Nigel Saunders finger for scale.



I suppose I could fashion/make one, or get a ceramic one instead of a plastic one.

Right under my nose. Well four hours north of me, but according to their FB (they posted in 2023) that they sell to a place 15 mins away from me. Many thanks.
