We had a sunroom built and the walls were double sided with a foam core the
inside and outside walls were the same there was no wood in the structure to
speak of. Just the panels and aluminum connectors. We put in a surface
mount fan powered electric heater and it kept the room warm enough in the
winter.

Since they had to run a subpanel for the electric heater having 240V for the
heater was no big deal

I live in Colorado your climate will be different. We found in the winter
we had to open windows as the hot tub got the room too warm. I would just
use out door furniture in the room.

We had a sliding glass door put in for the hot tub I would look to see how
large the hot tub you want is and then you can get a sliding glass door that
would fit it.

Only thing to make sure of is that you put in GFI breaker for the hot tub.
My tub had built in GFI but it was only for 1 leg so it did not meet code!

My wife and I would like to have a sun- room as a place to relax and
'get away from the world' (no telephone, TV, ect.).

My concerns about having a hot-tub within the sunroom are;
1) How would moisture effect the walls, flooring and structure? How to
overcome this
2) Do they make glass doors large enough to fit a 4-person (8x8') tub
through? (in case we need to remove it)
3) Any other unforeseen problems that I need to think about?

We would like to have a sunroom instead of a deck to keep out bugs and
outside noise. The room will face northeast and be 16x16 foot with
about a 30 to 32 inch
crawlspace. It will have aux. heat and AC with either casement or
sliding windows.

All input appreciated!
