Is a 1/4" slope over an 8' length hallway too much for floating LVP ~ the floor is completely flat but it slopes towards the back door. The LVP seams will run across the hallway, not lengthwise.

Flooring only cares about flatness.

People care if the slope can be felt. Your slope is about 1/32 of an inch over a foot. Doubt if you can even tell without good measurement.

The work to fix it is not worth it, unless doing it for a perfectionist.

Flooring does care(not like) any dips/hills/ridges on the floor. Those do need to be fixed first.

  • The floor is flat, with no dips, hills or ridges, so it sounds like we're okay.

Slope means nothing to flooring until you get so steep that it threatens to tear it loose from the subfloor. This isn't a structural concern whatsoever. Most people won't even detect that much.


That slope shouldn't matter for LVP. Even for a floating floor, that isn't anywhere near drastic enough to cause the finished floor to move or slide.

edit: I initially read the slope as 1/4" per foot rather than over the entire distance. I'd actually consider that close enough to a flat floor in residential construction.

  • Yeah, unless you're setting up for a silicone chip fab plant, I think most people would call 1/4" over 8' both "flat" and "level".
