Spray booth from shower stall for glazing pottery.

This is a super-cheap but highly functional spray booth I built. I started with a 28" wide fiberglass shower stall (I bought it at Home Depot). First photo shows the whole thing. I cut the top 18" or so off the shower stall, then mounted a cheap stove exhaust fan at the top, toward the back of the stall. The exhaust fan has two light bulbs in it and is normally narrower toward the front. It is actually installed backwards at the top of the shower stall, mounted by screws through the fiberglass into the sheet metal of the exhaust fan housing. Click on the center picture for a high-resolution version and you can even see the sheet screws near the top and back of the stall, as well as the flexible exhaust tubing.

On the top of the stall is a Harbor Freight $99 HVLP spray compressor (I love it!).

Toward the front of the top of the stall I put a board and mounted a cheap under-the-counter fluorescent light. This plus the bulbs from the exhaust fan give good light while spraying.

I have the exhaust fan and light plugged into a wall socket that is controlled by a wall switch just to the right of the booth. The HVLP compressor is in a second plug, on a separate switch. I also have a small turntable made from an old record player that will rotate at 16 rpm for consistent spraying coverage (not shown).

The bottom of the stall (last photo) has a standard shower drain that goes about 2" below the base. Jammed up into this is a hose size-reducer from a shop vac (also Home Depot). Under that is a five-gallon bucket for runoff.

The whole thing is mounted on legs from a cheap office chair.
