My builder uses Houzz Pro to plan the timeline and give detailed estimates and daily updates with photos of progress, and provide invoices at pre-agreed key points in the build. This made the whole experience much more efficient and stress-free.
Sorry I didn't notice your question earlier! The floor is 24"x24" slate tile from Ann Sacks. But it's not even shown in the photo & don't know if its available anymore.
