Well, the bath has migrated to the bathroom! What a surprise. A pleasant surprise, though. Dave was just removing his tools after setting the bath in place.
And there's even plumbing to take the water away. The dark gray area under the bath is actually some bricks, then covered in cement (rendered?) to stabilise things. And there are screws on the (soon to be covered) rim of the bath into the wall studs to also hold it in place. There's nothing worse than a rocking bathtub.
And the view from the outside shows water in the bath. I'm guessing that this is to add weight to the bath so that it settles properly onto the base.
Nothing too special about this - it's the now-insulated refrigerant lines running from the garage to near the porch, where they are sealed. If heating or cooling (and I would guess that heating is more likely) is required, than an earth loop system can be installed.
