Which materials make the best soaker tub?

[Annanvy]

I am looking for a reasonably priced standard size (60" x 30") bath tub that would enable me to have an occasional soak. I would like a tub with a water depth of 10â€-15â€. My biggest problem is determining which materials would retain the most i.e. cast iron, americast, bootzcast, or acrylic.
I am hoping to purchase something that is readily available so that we could install it by Monday (Columbus Day). That being said I have looked into the following, but I haven't gotten a chance to looked at everything out there. So, please help. Thank you.

Of those, the Kohler Archer and Devonshire would be nice.
If you really want to soak. If you're just going to shower, then the others would be fine.

That is a good tub, but I think the old or new slipper type clawfoots types really give comfort and back support. Especially look for length, so you are not forced to keep dumping water on your knees that are scrunched up.

About materials, Cast iron seems aesthetically better suited to john deere bulldozer engines than to a place to lay your naked body. I think those autopsy tables are cast iron or SS.

I would look for the americast so called, or for acrylic or all its variations, then finally copper.

The romans preferred marble, but the ones I see could rather give you a month in Tuscany with brekfast in bed for the cost.

Slipper in acrylic, thats my vote.

Thanks for the input. I also forgot to mention that I am 5' tall and my significant other is 5'10". So, comfortability should be considered.
