I've had the pelasure of using Robert Hall's darkroom sink. It is beautiful, and very functional. I just want him to make me one.

I have made an 8' and a 16' sink, stained with mahogony and coated with fiberglass resin. I use a little fiberglass in the joints to help it hold up. It has been in use for several months and my previous sink has lasted several years with no problems at all. links to images of old and new sinks... http://roberthall.com/dr/ and http://roberthall.com/newdr/pages/DSCF0224.htm Best of luck! -- Robert Hall www.RobertHall.com
