It is part of your shower head where you can use it to target spraying off your legs/arms, etc. to keep your back and wound/dressing from getting wet. I used my bench and hand sprayer to do a better than “sponge bath.” I was told I could not shower for 2 weeks and felt gross so I found a way to get clean in the shower without a shower. 😉 I kneeled over my tub and laid my upper body on my bench for support while using the hand sprayer to wash my hair. I used a back brush to help me wash my legs because you aren’t supposed to bend or twist/reach for some time after surgery.
