Hi

I'm planning on a back illuminated onyx or glass tile backsplash. My initial thoughts are to place the glass tile on either glass or plexiglass and illuminate it with either led lighting or a flourescent tube ( we'll have access to change the bulb). Not sure whether plexiglass will pass code as it's a new construction.

If I use onyx I don't need to mount it on anything but not all onyx is translucent in the colours we like plus it's much more expensive than glass tile.

If anyone's done this before would like their ideas, many thanks
