Where can I find the square shower curtain rod seen on page 120 of Inside the Not So Big House?
The architect of that house, Gail Wong, ordered the rod from American Drapery in Seattle, WA. It is a rod similar to those found in hospitals, and can be built into the drywall. There are several manufacturers of this type of rod, so you can find it by googling “hospital curtain rod”, “ceiling track”, or “cubicle track”. One manufacturer is Kirsch. They call it “Architract Series 9046”.
