$1.75 is the minimum and good for a 3 minutes enough for a quick rinse. Even though I am pretty quick it usually takes $5.
They have updated it to 3 and a half minutes. It was plenty of time for me to soap off and condition my hair. The showers start as soon as the coins are in, so be undressed and ready and 3.5 minutes should be good. Water gets hot pretty quick.
