Haven't checked what the Hot Tub crowd are doing. I intend to insert a fiberglass tub into cob. Plenty of older tubs available for free since motors and jets fail. I will glass over those things since I just want hot water without the undertow.

This is why I tell people NOT to build cob benches as demonstration projects. I've turned down several offers to build them and ALWAYS discourage others on this.
Cob benches get forgotten once they're built. Roofs are often neglected or not built at all. People plop their stuff down and break off a corner, or carve their initials into the plaster.
Without constant maintenance, a cob bench demo project can, in a very short time look like a demonstration of what NOT to do.
Unless you, the builder, live close to the site and WILL repair the thing, don't build it in the first place!
