Not sure on tile how well these would stick however on glass 1010

I actual had to move them around a few times and it was hell trying to get them unstuck

I could put a lot of force down on them without them even bowing slightly so im gonna say they would support bottles just fine on glass surfaces

I did put a small amount of water on the suction area and then pushed them on that removed all the air from behind the suction cups so that might help

I can imagine that unless your wall or tub surround is a smooth shiny surface then they may not stick that well to it

I say that because i gave one of these away to someone who tried it on their bathtub wall but it didnt stick because it was a matte finish cheap plastic tub surround that was not smooth
