Our boon tub has a hook on it. We hang that on the towel bar that's in the shower.

We hang our primo with one of those lanyard things for keys from a towel bar that is in the tub.

We have a towel bar in the tub, so I use a shower curtain ring and hang the tub from the bar (the tub has a small hole in the top). I still bang into it when I'm shaving my legs, though. So looking forward to not needing it anymore...

I'm sure there is some sort of suction cup hook at Container Store that you can buy. But we just stored ours under the crib. Worked perfectly and was out of sight.

We have the Ikea baby bathtub and there's a hole at one end which we use to hang the baby bathtub against the wall where there happens to be a towel hanger. I'm sure some sort of S shaped hook would work just as well as the carabiner we use, we just happened to have one on hand.

Can you store the bathtub in another room? That's what we do

Command hook?

Any suggestions for a hook that will successfully hang an infant tub in the bathroom on the shower wall? Our bathroom is so small as it is and this thing is a major obstacle. We don't have a bathtub, just a standing shower, so we have to use the tub, unfortunately.
