At the big box stores, the tubs are displayed up on the walls. If you go to a high-end bath store, they have the tubs on display on the floor. You should always ask the salesperson before hopping in! When you say "around", it is not clear which city you live in? There are many other things to consider. What material do you want the tub to be made from? Cast iron, or acrylic/fiberglass? Also, you have not mentioned whether the space can accommodate a free standing tub, or whether the tub will rest in an alcove surrounded by three walls? Will you have a separate shower? It's best to give as much info as possible to elicit the best response.

There is a large variety of fiberglass tubs on the market. I have no idea which one may be better than another.
Also, different stores carry different models - and store specials can change daily.

If you are looking for a heavy {read 600lb.} cast iron soaker tub, then I can personally vouch for this model. But then that is merely my opinion, and you may not like it at all.

Good luck with your search!

I've been doing a similar hunt for over a year. I looked at real Japanese hinoki ofuros... very expensive and high maintenance. I looked at all the available freestanding tubs, as I don't want a drop-in. For me, the standouts are the Blu Bathworks line. http://www.blubathworks.com/products/categories/freestanding-bathtubs/
I saw the 6' rectangular one in almost every New York showroom I visited this Summer.
What I like about them is that key distance from the upper overflow to the bottom of the tub... the soaking distance.

There could be, kabodi - what you are decribing is a kitchen and bath showroom! Let your "fingers do the walking", and see what you find. :)

We have plenty of space in the bathroom. The plans call for a 72x42 drop in. It is a centerpiece of the bathroom. Acrylic would be lighter. I have fallen in love with the carved granite free standing tubs but they weigh a ton, literally. I live between DC and Richmond but the home is being built outside of San Antonio.

I purchased a brand new one on eBay with free shipping and the faucet was included we love it!!!

Ps we paid under 2,000. We purchased the double sided soaker extra deep.
