Joe, thank you for your very prompt reply, and I really appreciate that your initial reply was a video.
To answer your questions from the video:
1)The height difference between the plank with pad underneath and the bathroom tile: Hall bathroom-3/16″, Master Bathroom-1/4″ (I also included pictures if that’s helpful for us)
2) I included several pics of the area at the top of the stairs. There is a closet/pantry in that area that’s probably not very clear on the drawing.
3) I included several pics of the plank locking system. If those work great, if you need a pic from a closer distance or different angle, I’ll certainly send more.
4) I included a few product pictures of all the materials I’m using including the underlayment product and the transition kits that I purchased at the same time I purchased the flooring. If you have any insight or thoughts on these product choices, that would be great! (as long as it’s not that they’re terrible, and I need to take them back. I think I’m well past the return dates on them haha. Although you can certainly tell me if they’re terrible. That would be good to know I guess!)
5) Your other questions: The flooring is going to be installed on a wooden/plywood subfloor. After considering your advice, especially the bit about waves possibly developing in the hallway from moisture intrusion, I want to install the flooring in an East-West Direction. I think I would like to start the flooring in the living room, as it seems like doing it there would require the least amount of working backwards.
Thank you so much for your time and help!
