Buying guides from the factory floor

Colour on ceramic is glaze chemistry, not paint. Why a swatch cannot promise a batch, and what to fix in writing before a coloured order.

Water absorption is the number that decides what a body is called. How it is measured, why firing sets it, and the one figure we publish.

A wall-hung pan is held by the frame, not the wall. What the frame rating means, who confirms it, and what to check before tiling starts.

The plate is chosen last and decides the most: cut-out size, fixing centres and who supplies it. What to settle before the wall is closed.

A concealed cistern moves the tank behind the wall and the responsibility onto somebody else. Who supplies the frame, the plate and the warranty.

Width, depth, height and rough-in decide four different things. Which number to check first, and which ones the installer has to work around.
