What is the little building called around a pool?

Question

Just want to know what this is called 

Answer 1

I don't think you mean "around" a pool. That suggests a building that follows the shape of the pool and surrounds it, or most of it. I think you mean "near a pool" or "beside a pool" or "at a pool".

But as you haven't told us what this "little building" is FOR, we can only guess.

Answer 2

Cabana, pool house, changing room. Only 3 that I ever heard of.

I don't know there's a specific term in the U.S. Not that common here.

'Pump shed,' isn't for human use. It contains filters and pump for circulating water

Answer 3

A cabana is one thing - a small structure for changing clothes, maybe has a bathroom.

Answer 4

For changing clothes?  A cabana.

Answer 5

Depends on its purpose, but a common term is cabana, at least around here where I live. The equipment shed is not usually called a cabana although it can be, so if you mean the equipment shed, well, then call it that.

Answer 6

When I was growing up, we called them bath houses, but that has taken on new connotations lately. These days, you could call it a changing room, pool house, or pool cabana.
