Something to bathe baby in

So we have a baby tub we have used to bathe our daughter in. It’s the kind that you put in the sink. Well lately she’s been getting very wild in the tub and pretty much covering the entire kitchen with water. She loves splashing! So we were thinking about getting her something else, the only problem is, is that we don’t have a tub, we have a walk in shower. Does anyone know of anything we can get that would work in the shower? Everything I have researched is all for a tub.
