16mtr, 600 by 600 porcelain kitchen floor on ply ? advice please !

[2020Tiling]

Hi ! iam after some advice on this one thanks. Ive got a Porcelain floor to tile in 2 weeks time, the tiles are 600 by 600 mat black slate effect with a hint of a silver speck when the light hits it. Anyway the floor is solid after been over boarded with 18mm ply on top of solid floor boards after nogins have been fitted etc, the floor has no deflection. ply has the correct expansion gap etc. The problem i have is thers an old chimney stack that has been replaced leaving a concrete slab where the cooker is and this sticks out around 12 inches from the plyths , so the ply has just been butted up to the concrete and is slightly higher than the ply floor? also the floor isnt 100% flat /level in places. just after your views on how the best way to prep this would be ? theres no ufh. I was thinking slc on the dips in the floor then ditra , but unsure how to tackle the old chimney slab ? what do you guys recon ?

I'd ditra first then level, this floor has to be bang on as 600x600 can be a nightmare unless the floor is totally flat, as for the concrete, it depends how much higher it is, will the height be lost once levelled??

I prefer Hardie or similar rather than ply but in this instance I'd level first then Ditra. Ditra should be directly under the tiles to benefit from its uncoupling properties.

I too would level then Ditra not sure if schluter recommend levelling compound over ditra but I may be wrong as things do change from time to time
