Correction for tiling an unlevel floor

JPT1 · 03-27-2012, 11:44 PM

I am planning on installing mosaic marble (floor) and 3x6 subway tile (wall) in a 36 sq ft half bath. At one point this was a back porch and is pitched. I am out of level by 1&1/4 inches across the 64 in room east to west. The subfloor is solid and flat, I was about to fix my hardiboard when I realized how out the floor was. The height is 82 in so I don't have a lot of elevation to work with. I see my options as 1. Make up the difference in the first layer of subway tile, which leaves one side of the room with a first layer of only 1&3/4 on one side and cutting the north wall first layer on an angle to transition from E to W or 2. rip up the subfloor and somehow level it with shims or something.
I welcome input on how noticeable option 1 is, how to implement option 2 or other miracle fixes
Thanks

Pull off the subfloor and sister in some level floor joists---

Or use deck mud and self leveling compound---http://www.diychatroom.com/f80/mud-what-77763/

Thanks, you got me away from the tlle remedy.
I couldnt open the link you sent.
I can't take up the floor for a few reasons. It seems like my best bet is the leveling compound. If I use this can/does one fasten hardiebacker on top or tile on the leveling cement? Are you aware of any depth limitations on leveling compounds, what is the thickest and thinest I could go? Lastly is it ok to use this stuff in a stepwise approach starting at the low end and doing several applications to work up to the high end?
Thanks
John

My computer is FUBAR---sorry---go to the tiling section--that is a 'sticky' at the top--Bud Cline wrote it,well worth reading.

Tile is set right onto the Self leveling compound,no need for a backer--

Add sand to the deep areas ---stretches the product and makes it stronger----

If you use deck mud--pack the deck mud on top of a wet layer of modified thinset---that will aid in bonding the deck mud to the subfloor---
