Public Swimming Pool - asian part (Istanbul)

Hello,

I am looking for a public swimming pool on the asian part (Atasehir, Ümraniye etc).

I now that the swimming pools of Belediye require a lot of tests. I just want to go swimming from time time. For that I am looking for a pool (closed) which does not require me to present any health certificate. I just want to pay my fee and swim maybe one hour.

Any help
thanks a lot
