Drain too high - Tile Advice

[john3055]

Hi,
New member and rookie homeowner from Australia here. I am in the middle of my first bathroom build at home, and have an issue with the drain height.
where i am at :
I hired a contractor to come and level the floor prior to waterproofing, he sloped all the falls to the center drain which worked well. I installed the puddle flange and recessed it in to make it flush with the surface (think this is where i went wrong, think it should have been recessed below the floor).
the surface has now been waterproofed and read to tile. problem is that the drain (tile insert style) sits up so high that the thinset would need to be about 13-15mm dry thickness for the drain to sit level to the tile. I intended on just using a thick layer of thinset to make up the difference but it is going beyond the specifications of the product (Davco smp evo), and my skill level. I have already cut all the tiles around the drain ready to be laid so makes it hard to find a slimmer drain.



Looking for some advice ....

my options at this stage appear to be,
1, raise the shower floor again to accommodate (not ideal as i would have to raise the entire floor not just the shower area)
2. cut the drain down and try get another drain to fit into the housing
3. find an adhesive the would suit for this application

any help would be great hope that explanation helps cheers john

Only options I can see would be to take the drain to a metal fabricator and see if it can be cut down, have seen those types before they are excessively high. Or could the drain be set into the floor? If a channel was cut out first and water proofed, then the drain could be dropped in on adhesive flush with the tile. Will mean cutting down the waste pipe as well. Hope it goes well
