Now that we're nearing the end of work on the inside of the house, it's
time to start considering the outside. The biggest change there will be
a deck across the back of the house. I'd really like to have a hot tub
sunk into the deck.

Neighbours of ours have a hot tub on their back patio (I think it is
fibreglass with a wood surround).

We were quite taken with the idea until we discovered that it is filled then
chemicals are added to stop the water going manky - so you are tubbing in a
chemical stew (much like a swimming pool).

They love it, and use it most days winter and summer, but we were a little
put off, liking the thought of fresh water each time.

I realise that a hot tub hold several times the amount of water that a
normal bath holds, and also that most times the location is not chosen for
suitability for drainage or filling directly from the hot&cold, but has
anyone seen or built a hot tub which is plumbed in more like a normal bath?

I guess you could run H&C in insulated pipes, and have a 'sump with a pump'
if you are in the wrong gravitational direction from your main drainage, but
this would make life somewhat more complicated.
