absolutely not haha, the verb 'bathe' can mean both, but 'take a bath' can only mean 'wash yourself'. It could possibly work to say 'take a bath!' as a joke when throwing somebody into the sea. But as a suggestion or command, it can only mean 'you smell, please wash yourself'

No. That means clean yourself. You could say, 'Have a swim' or 'Go for a swim.'

Hi, You would be better off saying “go for a dip” or “go for a swim”. “Take a bath” doesn’t have any other meaning than actually getting into a bath. You could make someone think that they smell bad!

No. To take a bath would only refer to getting into the bathtub in a bathroom. 🤗

“Take a bath” isn’t really used in that context, but you could say “take a dip”.
