To think you supervise small children swimming, even in the showers

[EWLT]

and that this is a fuss over nothing?

I swim at a small privately owned pool, where there re also swimming lessons.

They have had a lot of trouble regulating the shower temperature which has been luke warm for a few weeks. This week it was hot. Personally I like a hot shower, especially after swimming, so it was an improvement for me, but at the hot end of what I'd consider Ok, even for me IYSWIM.

The young children were coming out very pink. Parents have been making a huge fuss about how "dangerous" it is and how unwell the children felt afterwards.

I absolutely understand that it needs mentioning to the owners so they can continue to work on a solution, but dangerous? And wouldn't you be supervising young children (infant age) in the showers, so if it was too hot and likely to make them feel ill, you'd take them out?

Who are all these children that would go in a shower too hot for them? Mine would get straight out

YANBU but then I'm the sort of parent who lets her DC run around barefoot indoors and out. Some of my mates chase their DC with slippers all year round as if their feet might fall off otherwise.

One hot shower won't damage them...and if it were SCALDING any child would simply run out immediately it touched them!
