Roman tub

I have a question about roman tubs. How hard is it to put one in on a pier and beam house (first floor). I have such a small bathroom and the only tub I can find is a 54" that will fit but it is very shallow so I was playing with the idea of putting a roman tub in so I can make it deeper. I have set tile but not in a tub or shower. Any ideas or help would be greatly appreciated!

what about the Kohler Greek tub? That is very deep.

I checked that tub out and it would work but at almost $1000.00 Would it be more cost effective to buy that one or build one? My budget only allows $400.00, excluding the fixtures and plumbing costs.

That is tough indeed. I decided to rework my plan for lack of tub options.
