This is the ONLY gold colored door on Amazon in this size.

10mm Glass, Anti-fog,  Stainless track, Sealed bearing 

For the water control I like Delta. Should you ever need parts the $5 more in cost is worth it.

For rain shower heads over 6" wide be prepared to add more supply lines to feed it. 3/4" isn't enough.

Smart valves and controllers are insane.

LED Niches are by far the best bang for your buck. They can be expensive, but not if you have me on your team.
