Samples
I had ordered the samples from Outwater a few years ago. They sent a whole ring of 20+ 6" samples.
Warning: I tried the brushed metal/silver moulding (couldn't help but get fancy) but there is a plastic sheet on top of the silver plastic which starts to wrinkle after a while in the corners. The pure plastic (such as Red or Wood Grain) does not have that problem. BTW, you may want to try to order less than the minimum length. They worked with me, and I got just what I needed.
