Welcome, Chris.

I trust by "timber strands" you're referring to your floor joists (a geographic location in your User Profile would help here)?

Have you evaluated the joist to determine their suitability for a ceramic tile installation?

The quarter-inch plywood needs to be removed before installing the Ditra. The nominal 3/4" OSB meets Schluter's requirements for subflooring, but you'll need to select a thinset mortar whose manufacturer will accept bonding to that material.

My opinion; worth price charged.
