I have been taking a shower with my catheter since February. Here is how it works. I wash off with Body Wash at the sink. Then, I use two small hand fills of water to wet my hair and use a small amount of shampoo, rubbing it thru my hair. Next, I take a heavy and CLEAN towel, folded it into fours, so there are four layers between the water and the catheter. Now, I am ready for the shower. I turn on the water and I gently step into the shower tub, be careful in case the tub is a little wet, making sure the catheter is covered. I can rinse my entire body except for the catheter. You can rinse your neck and head, just make sure the catheter is covered with the clean towel, rinse slowly. Do not worry if the tape off of the catheter gets wet, it will not cause an infection. Now, when you are done, use a mask and gloves to change the catheter, DO NOT change your catheter without gloves, mask, and clean hands. When in the shower, move the bottom part of the catheter that is flexible and rinse, making sure the bottom part does not get wet. Water=GERMS. When you come out of the shower, have a clean, handy towel to wipe off your hair, so the water does not get into the catheter. When done drying the hair, remove the heavy towel away from the catheter, making sure there is not a threat of water going into the catheter. When cleaning with water with the neck, head, and hair, press hard on the towel where the main part of the catheter happens to be, so the water has nowhere to go except away from the catheter.
