I was going to write something along the lines of :

but no point being repetitive.

Not only are the constituent materials high in embodied energy, they are  
configured in a way that makes re-use or recycling pretty much impossible  
once the service life of the ferrocementi construction comes to an end,  
violating yet another of the primary tenets of greenbuilding.

Just thinking out loud for a moment...

If concrete was being contemplated as a material choice for the hot tub  
vessel, what if one were to re-use the pre-cast concrete staves that are  
used to build stave silos (and biogas digesters in Third World countries) ?

Closed-down farming operations are (sadly) an ever-growing resource and  
the structures (including the silos) usually have to be demolished.

And once the hot tub has outlived its usefulness, the silo staves could be  
dismantled and re-used elsewhere.
