Thanks everyone! These are all great suggestions!

Kohler Archer It's acrylic; decent price.

It's not heavy and it's deep enough to take a real bath, but easy enough to step in to shower. We like it.

We found a Kohler cast iron tub for $375 at home depot - Kohler villager.

Kohler Mendota. Excellent tub.

I got the toto soaking tub- enameled cast iron. List for $2608 but I got it for 1/2 of that at supply.com. So far so good. I've been using it for over a year.

We just purchased this Jacuzzi soaker tub that is wonderful. The ordering and delivery process from faucetdirect.com was great too.

We got a kohler for about $600 that is nice.

We're replacing a tub. All the reviews on basic tubs (and even higher end ones) have me worried. Anyone have a recommendation for a good one?
