"Have a shower" vs "Take a shower" [closed]

According to take-a-shower-bath-or-have-a-shower-bath, there are already many answers there, but it's still not clear for me.

I still wonder that

Have a shower and Take a shower, are they the same or not?

Which one to use?

To use Have a shower or Take a shower, it's dependent on context? or maybe is dependent on English dialect?

Solution 1:

According to Oald it is "to have a shower/to take a shower" in BrE. "to take a shower" is especially used in AmE.
