Has anyone tried this?

[Dandy's mom]

Now that I somehow have ten ducks, I’m looking into different pool options. My personal favorite is an antique claw foot bathtub. I’d have to put it up, on stone or maybe a wood platform, and build stairs. Other than that, do your duck minds see any issues? Did they used to paint the exterior with weird toxic and/or lead paint? Is rust dangerous? Anything else? I’m very attached to the idea of watching my ducks bathe in an actual tub.

Well, My duck lives indoors, HATES outside and swims in my 5 million year old metal tub regularly. According to the vet, she needs enough room to dive to keep certain muscles strong. Never heard of this, not buying a full sized pool or digging a pond. Iv'e had ducks for 15 years, and most spend st least some time indoors. All have bathed in my tub. In fact all but Dandy have brooded in my tub too. I pick her up and put her in since there's no room for steps in the bathroom, but I have to close the curtain or she jumps out because she hates water, go figure. (hasn't hurt herself jumping out and lands fairly gracefully) I say go for it. We turned an old tub into a flower bed and it turned out cute.
