Kohler Villager, cast iron so will be heavier, but durable.

You can't beat cast iron for durability and low-maintenance. Heavier (make sure your floor joists can support the weight), and might cost more, but well worth it IMO.

FWIW, we have Toto 1525's. Love 'em.

I'm not sure our floor can support a cast iron tub. The kids bath is on the second floor of the house and the framing is all done.

We can put the cast iron in the basement bath, though.

Any recs for a second floor bath (where it's too late to reinforce)? Thanks!

Well I don't know if typical building needs re-enforcement for a cast iron tub. I had a cast iron tub for 70 or 80 years on 2x8 joist that were 21" on center. The typical joist spacing I believe is 16" on center. Check with your builder or contractor for what they think. It used to be that cast iron was all that was available in houses. All second floor, old old houses, had cast iron tubs.

Good idea, enduring. I'll ask our contractor today. We have a fair amount of support framing in the house b/c we're downslope on an earthquake fault !

Our contractor said a cast iron tub on the 2nd floor is no problem.

Thanks everyone! Two tubs down, one more to go :)
