FAQ

Direct answers

Why does bathroom waterproofing matter?

Because Melbourne bathrooms fail years later at wastes, upturns, and penetrations — not at the tap. A pretty tile on a skipped membrane is a second demolition with interest.

What tile choices work in wet areas?

Porcelain floors with a slip rating you can live with, a size that can still take a fall, and grout you can maintain. Large slabs look calm and show lippage. Ask the tiler how they will form the fall, not only which colour they like.
