I'm looking to make a bird bath with a saucer 14-18 in. wide. All the store-bought ones I've seen are either too small and shallow, or, large but very overpriced. Also I'll probably mount it to a 90 degree plant-hanging bracket placed on a fence post, with the arm underneath the saucer.
I've read 2 in. depth of water is advised, with either rocks with sloping sides in it, or, a saucer with sloping sides that are shallower at the edges and deeper in the center.
I've seen plastic 18 in. saucers that are 2 in. deep, but read that plastic edges get very hot in summer sun, while ceramic doesn't get as hot.
I've seen ceramic saucers that are 14 in., but once a little wider they become much more expensive. I'm also not sure how to mount the bottom of the saucer to the plant-hanging bracket, unless I mount a plywood base under the ceramic saucer.
If you also know a good quality and good value commercial bird bath, appreciate that too!
