Your center might give you some extra supplies for your catheter (like tegaderms) if you ask. It is a pain and my tegaderm always starts peeling up at the bottom.Like StaceyandJoe said, I've learned to love baths and I wash my (long) hair in the sink. Tried leaning back in the tub and sticking it under the running faucet, but I always managed to get the catheter wet when I did that.
