re: Free standing soaker tubs

I’ve got an acrylic soaker tub from Kohler...I think it’s the tea for two model. Extra wide rather than extra long, and not freestanding, but like the previous poster said, it holds the heat really well. One thing to note: if you end up with an extra long soaking tub, you may need a hot water heater upgrade. I ended up with two 50 gallon WHs plumbed in series to ensure I could actually fill up that big ol tub without running out of hot water....or so someone could immediately take a hot shower just after I filled the tub.
