To level or not to level?

[Wsl1]

Certified newbie here. I am midway through a bathroom remodel. Ive attached a pic of progress. Older home, 2nd floor bath with plywood subfloor. I noticed floor is sloped with high at window and low at hallway door. It is pretty flat though. Floor was 2 layers of vinyl before. I am ready to put in porcelain tile. I bought Hardie 1/4" and thinset. The slope is about 1.5" over 10 feet. Im nervous about trying to level it out with Henry 555 as i do t want a huge jump from hall to bathroom. Any suggestions? To be honest we didnt notice this while living in the house before i tore everything out. Thanks a ton.

If its flat who cares if its level?

Yeah, you can level yourself into a corner for sure. We mostly do flat, level is extra and then that may be an issue with doors and such.

If you see signs that the floor is sinking (gaps under wall, base molding pulling away from floor, drywall cracks, etc) then the core problem should be addressed. It'll only get worse over time. Otherwise, it's flat so go for it.

Looks like the picture is vertical LOL but I agree with the pros, if it's flat... proceed
