Are bathtub sizes the rough in size or the tub interior size

bathtub

I am looking at installing a tub and the sizes are not clear what they are.

For example, the "Amiga" bath gives dimensions 72.0″ L x 36.0″ W x 21.0″ H. Is the 6 feet the size of the rough in, or is it somthing else?

In other words if the studs of the wall are 6 feet apart will the bath fit in there?

All tubs come with "rough in" size specifications which indicate necessary framing/opening dimensions for your unit specs. They can often be found online.

Interestingly, yours says:

Dimensions provided on rough-in diagrams are nominal. Measure your actual unit upon receipt and build according to the actual dimensions.
