Just finished our master ensuite reno in North York and want to share the tile work details since this was where we had the most contractor education.

The Kerdi membrane was non-negotiable for us. Previous owner had used durock + RedGard in the main bath — it failed at the corners within 8 years. Kerdi bonded system has no such weak points.

Large format tile on shower walls: the seams between tiles are nearly invisible. Worth the premium labour cost in my view.
