After measuring the width of the bathroom it was at the longest point 200 cm long and that's the longest tension stick they sold in the hardware store which fits exactly as you can see in the pictures, only one slight problem went to the hardware store and bought a shower curtain to 240 by 180 which is way too short need something more like 210/215/220/280.... any length would be perfect I can always cut it to size.
Didn't think that would be my problem that I wouldn't be able to find a shower curtain.
And in the white bathroom it measure at Max 170-180 cm which fits perfect.
If you pay close attention you'll see a tape measurer in the corner which is how high the curtain reaches at 180cm, a tad too short.
