I have almost always seen toilet paper rolls presented on a telescoping plastic piece when available for use. A few times I have seen them presented on a much simpler solution: a simple rod with an upward curve on one end to keep it from falling off. Typically this is presented as a "rustic"-looking design choice, but it actually seems preferable in every way to the telescoping plastic piece:
- Faster to replace the roll
- Sturdier (no moving parts)
- Does not require touching a plastic piece that has probably been touched by dirty hands.
Why is the telescoping plastic piece ever preferred?
Option 2, except normally it isn't hinged, so the roll is held slightly from the wall Santeri Viinamäki [CC BY-SA 4.0 (http://creativecommons.org/licenses/by-sa/4.0)], via Wikimedia Commons
