Cob: Free standing shower

[Bob]

Dear Cheryl, et al,

The simplest way to bend copper or conduit tubing is to fill it with sand
first, This prevents  it from collapsing when bending.  Then just bend it
around a 50 gallon drum.  It will spring back to a larger diameter, which
is just you will want.  There is no point in soldering the ends together.
Just stick something in  both ends, even a whittled down piece of wood that
could be wedged in.  Better yet, with a pipe bender you could bend the ends
the other way so they would connect to a bracket attached to the wall.
