Shower enclosures

What slopes under the shower? What should the correct slope be?

When planning a shower in the bathroom – especially a walk-in one – we usually focus on choosing the tiles, the drain or the enclosure. Yet one of the most important elements of the whole construction is a correctly made shower floor slope. It's precisely this that determines whether water will drain efficiently to the outlet or start pooling on the floor, forming puddles and causing damp.
