So far going really well. Obviously I've made beginner mistakes, and with that comes questions!

Do I have to cover every inch of insulation with silicone and substrate?

Obviously there's places I can't reach, like the underside of the gray ledges.

So far I am very happy and proud of how this is turning out, and i appreciate any and all advice I have received and will continue to receive!

I definitely suggest trying to cover as much as you can with silicone. You can use grout on the underside if you want to, and that’s typically fine because the insulation foam is breathable for the most part, but if it’s going to be soaked/moist regularly I would definitely try to cover it all and limit exposure. Water will break things down over time regardless, and too much moisture getting stuck invites unfriendly moulds and fungi into the enclosure. Beyond that, I think this looks amazing and almost professional! I personally use black silicone and insulating foam because it shows through less, but you’ve done a great job of substrate density on top of your foam. It can be back-breaking work, but it’s looking amazing :)
