Hello all-
Looking at a house, slab on grade construction. Tile in bathrooms is cracked along a line indicating some settlement, but there is no measurable deflection. Is tile on top of tile an OK fix, or is it recommended to tear up the tile and seal any cracks in slab prior to re-tiling? The house is on top of a hill, so don't think water seepage thru slab should be a big concern?

Oh I know the best way to do it would be to tear up and use a crack isolation membrane, was just wondering if tiling over is an acceptable practice.

It is an acceptable practice as long as there are no known issues with the existing tile assy.

If you choose to go tile over tile, then you need to be aware of the finished height of any other material (carpet, laminate, wood,) that meets the tile under the door. If the finished height is lower than the finished height of tile over tile than you will need to fabricate some sort of ramp tapered or feathered out a ways back from the door, so that where they meet under the door is the same height so as to not have a tripping hazard/bad look. Or figure out some sort of transition material such as a thin piece of wood trim to go over the top of the transition. Also most likely you will need to cut some height off of the bottom of the door if it swings over the tile.
