Floating floor replacement - Tile Advice

[Dan]

You'll be retiling that a lot sooner if you ply it and tile it. Send the "tiler" to the forum for some training

No matter what the substrate, ply is not a suitable material to tile on to!
A professional tiler who is up to date with latest practises would know this.

I'm not happy tiling into ply and I've made it clear I'm happy to pay to have the floor ripped out and replaced with Marmox at my cost! I want a job that is done correctly and 100% not to fail through inadequate substrate

Is the solution I proposed a sound one? I've seen this recommended in a few threads as a replacement for the Floating Floor.

rip out and replace with insulation board is the way I go.
and at that point I normally recommend fitting wet ufh to clients which doesn't add to much to the cost.
