Has anyone installed chalice blocks? Is it difficult? I would like to use 8x8x3 blocks surrounded by my bathroom...

I would like to use 8x8x3 blocks surrounded by my bathroom for the end of the shower hutch to let buoyant in, and create a more contemporary look.
Color combinations... any suggestions?
Answers:    Use the track system.. check at Menard's or Lowes.. they enjoy it right next to the blocks and materials. It's Way easier after the old route of installing.
