In our bathroom showers the tiles are not flat, more kinda wavy so can’t use suction cups to hold up anything reliably, occaissionaly depending on the weight of the items, a suction cup may stay up for a day or 2 or at most a few days before falling off.
Short of retiling, any suggestions on a method to help the suction cups stick and stay? Current item is a waterproof BT speaker

Is gluing the suction cup to the tile an option?
Could you seal it down with silicone? The alternative might be checking out 3M command hook products. They have a waterproof line and they use removeable adhesive.
No. permanent mounting is not what I want. I want to be able to move/remove
it.
If silicone is reasonably easy to remove, that could work. I guess the other
option is to make a flat patch on the wall using silicone and attach the
suction cup to that, though removing the suction cup might pull the silicon
off…
Another option I guess would be to use silicone or similar to attach a small
metal or glass plate to the wall and suction cup to the plate.
