Today was all about the subfloor. The first layer was 2'x2' particle board pre-glued with a plastic-rubber-compound moulded tile that creates airflow for warmth and a smooth surface. That's what went in today. Tongue-in-groove format meant cutting incredibly complex angles to fit around angled walls, toilets, door frames and casing. Hard on my small brain, but fun to figure it out. Got it done but not without an extra trip to Calgary to pick up more tiles and lots of sawing, sawing, sawing.
