Germany:

I checked the rules.

Although there are a ton of regulations, surprisingly none seem to reference the height, size, etc. of a toilet (seat). That's surprising, if you consider the minimum spacing of the toilet to the wall, door,... is given (see page 10 - 15).

But there is this "catch-all rule"

(10) Durch Einrichtungsgegenstände oder bauliche Einrichtungen in Sanitärräumen dürfen Sicherheit und Gesundheit der Beschäftigten (z. B. durch Schnitt- oder Stoßkanten oder durch die Möglichkeit zur Ansammlung von Krankheitserregern) nicht gefährdet werden. [Page 5]

This basically translates to "Furnishings and physical structure may not endanger safety and health of the employees". The examples given are referencing e.g. sharp edges or possible accumulations of pathogens, but in the end I think that intentionally inducing strains is not very ergonomic and could be considered a health hazard.
