How Much Does A Concrete Bathtub Cost I Would Like To Replace My Regular Bathtub With A Whirlpool Tub.?

I would like to replace my regular bathtub with a whirlpool tub.? - how much does a concrete bathtub cost

I get the bucket of the same size or can I learn more? I would have preferred a larger bath. My current tub is 60 "x 36", but I would by a 60 "x 42". My house is built on a concrete slab and I can not change if the drainage.

Are there any companies that whirlpools production to flight, put to be where I specify the correct target?
