Get an extra-long hose and extra-comfortable tip!
Just screw this onto your shower pipe or sink, and you'll be ready to clean up in comfort. The hose is a full two meters long, 7 inches longer than a standard 6 foot hose. That gives you plenty of room to maneuver. The tip is smooth and flexible pvc for more comfortable insertion. All you need is a shower diverter valve to turn it into a more permanent solution.
A little bit of lube on the tip will make the whole procedure more comfortable.
