It has come off a few times after very hot baths with a lot of steam, and I ended up placing it somewhere to put the soap in. However, while it was attached, it held the weight of large soaps.

It would also be helpful if it was closed from the bottom so that water doesn't drip if, for example, you place it above the faucet
