Hello, you could try instead of removing the paint add a liner. You could try kijji or craigs list for used pond or pool liners. Or because the tub is small try off cuts at a pond store. You would need to get creative to tuck or fix the liner to the tub, but it may be cheaper then trying to re epoxy and this way you would know there wouldn't be chemicals leaching into the water. Just a thought good luck.

One of the Florida gal's (Kara) lined her in ground pond with a used billboard - at least that is what I recall her calling it. Road advertising sign. Somebody(ies) re-market them as pond liners when their air life is complete. That might be an affordable option.

I got my liner at the Habitat store. Unopened. I might have been lucky.

As for affixing it to the rim of the tub - Monster glue!

Be sure to post pictures!!!!! I would love to see your project in-progress -- and definitely the finished product! It sounds really fun!

Why not just wire brush t until the paint stops flaking off?
