Installing 12mm laminate over Oriented strand board

[highup]

Just looked at the images of the hallway. Looks flat, just slopes towards one side. That's less of an issue. I see doorways on the left side. Where does the opening on the right side go? More hallway or into a room?

Hallway is about 25 ft by 4 ft
The slope is very gentle, the opening on right goes to the staircase landing and then to the bedroom in the pics

I don't think that slope is much of a problem as long as everything is flat. Just be sure like you did before to sand any of the high spots in the OSB.

Thanks for your support, I managed to install the floor on the first bedroom,

I'll post more pictures once is cleaned up. My next challenge is going to be the hallway ,this is NOT level at all, there is a slope of about 1/4 inch that runs across all the subfloor in that area.

My guess is that I'll need a T reducer, given that the hallway and the bedrooms floor height is different right?

Yes but slopes can be within industry standard of flatness. There are pitch standards too.

Had a job 20+ years ago with Pergo. Enclosed front porch that sloped 2 inches in 6 or so feet. I don't recall if I checked for an industry standard for that, it just seemed wrong. I told em to pick out a different material. (indoor/outdoor carpet) I don't know what pitch is considered acceptable, but looked more like a slip/hazard issue than something that wouldn't actually work.

Thanks guys, Im just about to install the first transition between the laminate and bathroom tile floor, however the reducer does not match the height of the floor, tile in the bathroom is about 1/2 HIGHER than my laminate.

can you please look at the pics and share your thoughts ?

The first photo would be the best choice, but there is a different trim edge called a threshold molding. It has a square edge with a rounded or radiused top edge instead of that tapered edge you now have. Butting the threshold trim close to the tile would allow you to use grout caulking to make a nice finished edge.
The one you have is designed to go from the wood height down to the original surface.
