Thanks for bringing up this topic!
We have a tub that got chipped by contractor #2 while doing the tile. We've bought a kit but haven't tackled the project yet. Meanwhile we have this cool 4' square tub that we moved to the basement... it was already peeling some, but now (having moved it down two flights of stairs) most of the bottom has peeled off and generally the whole tub looks pretty awful.
I know five years ago it was $300 to do a clawfoot tub in Maryland, and I think it was worth it. I talked with one company at a home show at the state fairgrounds about it. Through asking around, I got the impression that $300 was the standard rate, and that not many people want to fuss with it.
