Wet room

Joe:
Since it will be a very large space (larger than my whole studio)
might I suggest you check out http://www.farmtek.com


This online farm supply store can sell you 4X8 sheets of
something called "Gel-coat" (sp?), which is a fiberglass coated
sheet material commonly used to cover the walls and ceilings of barns,
animal stalls, etc. Easily joined together with "H" strips,
much as one would join wall panels in a home (seal with
any good grade silicone caulk for waterproofing.) Hose it
off, or pressure wash it. Comes in white and grey, I believe.
We often recommend it to our clients who own bars, for use
in the bathrooms.
Works extremely well in wet environments, and relatively
inexpensive.

You will want to plan for plastic shelving, so that mildew and/or
rot is not a problem. And be sure to include a supply of water
such as a small utility sink, for those times when adding
moisture in the form of a mist from a sprayer is desired.
Any "garden variety" humidifier, connected to a water supply is a
good choice, since you can set the percentage of moisture
you want in the atmosphere of the room. Plenty of lighting too
which may have to be waterproof outdoor style fixtures, unless
you're planning on growing mushrooms as well as pots g

I have no connection to the company I mentioned,
other than being just a (satisfied) customer.

Best Regards,

Wayne Seidl
