Hot shower in the hoophouse

I have a large hoophouse that I would like to install a shower in so im not showering outside in the cold. Any thoughts on this? should I be worried about condensation etc.. thanks

Humidity (up to a point) is usually a good thing in a greenhouse.

I did this for years and years when I had a plastic greenhouse, and it was a delight to shower out there among the plants in the warmth of the afternoon.  I think the plants enjoyed it too.
    Even better than a hot shower in the greenhouse is a hot tub!  A friend of mine has this, and fires it up on the coldest nights with a woodstove.  The added benefit is he leaves the hot water in the tub overnight to help heat the greenhouse.
