Getting bathroom subfloor level - laser level

[branimal]

Any recommendations on tools / lasers to get a subfloor level?

Or do you guys just go with a 48" level?

Whats an acceptable tolerance of slope across say 48"?

Thanks

What kind of flooring material is going in the bathroom? How is it out of level now, slope to the walls, high and low points, etc?

When I lay tile I run a 4' level over the floor and see how bad it is, and use that as a gauge to know where to start for the high point and work it out as best I can. If it is really bad I get floor leveling Ardex and go to town filling in the low points to match the high points unless I need to lower the highs to match the low points.

Flat is usually more important than level, within reason

I use a 6' level but they can be a little pricey if you don't have one.. A cheaper way is a straight 2x4 on edge with a smaller level on top..
As far as whats acceptable, everybodys has a different theory on that, but a lot depends on your finished floor material..

Laying down cement board then tile.

checked my wooden subfloor for level using a 48" level.

Here's a diagram of how off the floors are. So +3/4" means the point 48" from the center is higher than the center by 3/4"

How bad is this and how would you go about getting it more level?

Seems like the middle point is low.

I don't want to raise the floor to the high of +3/4".

The non measured areas have rotted subfloor which I am replacing.

Finished floor material is ceramic or porcelain tile.
