The roll flies off and the piece that holds the roll keeps loosening up and falling off.

Try reversing the direction of the holder. If the piece that loosens up is threaded and not a piece that you need to remove to replace the roll, then get some LockTite thread locker. You can easily find it in auto supply stores.

We have Ginger's Motiv line tp holders and towel bars in our bathrooms. We used Sine in the MB (mine) and guest bathroom, and Frame in the hall bathroom (DH's). No problem with any of them. Easy to remove the empty tp tube and pop a new roll on the holder, but no tp rolls flying off while unrolling.

We have a slipon one from Lowe's in both bathrooms. No problems at all. I have seen some public restrooms where it's installed so it's pointing upward - no chance of the roll flying off, but we have it so the open end is away from the person using the facilities (pull toward you to tear the tissue).

I can definitely see how reversing them would help. Do you like the look that way?

The wall ends not too far from where this is, so depending on the dimensions we may or may not be able to do it. It would definitely be easier to slip a roll on and really nice not to have to pick it up off the floor.

We pointed our upwards in two bathrooms and like it very much.

i bought one from kohler that points upward, it has a ledge at the base to hold the TP, love it.

I was just looking at one that was like that. It sure would be easy to drop a roll on there.

Zookeeper93 and Meris - do yours loosen up?

Ginger calls this a spare roll holder. Does anyone use this as a regular holder or know if it could've be? This is from the London Terrace collection but one in the Chelsea line too.

I also like this from .the Columnar line - it looks like it would be solid.

I used Restoration Hardware for all of mine. Spring loaded and excellent quality. Mine are 13 years old -- 0 issues ever.

I don't care for the open ones as I find the rolls tend to go flying off. Ginger also is a good brand.

Just last week I installed a Brizo open toilet paper holder. It looks great and I have no trouble with the roll falling off. It is installed horizontally, the usual way.

I finally get fed up with the wiggly TP holder I got at Pottery Barn. It's just a bad design having one attachment point holding a horizontal roll with constant pulling and tearing. I found this one at Rejuvenation. It costs almost twice as much as the PB holder but it's very stable with two screws. It's also got much more heft and coordinates well with the other PB items in my bathroom. Yes, it was made in China, but it makes the PB one seem flimsy in comparison.
