fixed window allows light and second window on side opens a little for air. sink drains into a barrel outside. tall table used outside for spraying glaze. found the sink in corian countertop on craigslist never realizing it was the exact size of the old doorway. putting it in made a huge difference, now i have to leave a stick for the lizards who find their way inside it so they can climb out. still need a bucket inside for first rinsing but it is really nice to just go a short distance to throw that dirty water on the plants outside. mosquitoes would love me to leave the drain hole open. not gonna happen.
