Quick answers
How is a built-in wall niche made inside the shower, and at what stage of the bathroom renovation is it built?
A built-in shower niche is formed at the bricklaying and plastering stage before tiling begins, waterproofed along with the shower walls, and lined with matching tiles so bottles sit neatly inside the wall.
A built-in wall niche inside the shower is the neatest way to hold shampoo and soap without wire caddies that rust or hang off the glass. Because it is recessed into the masonry, it has to be planned before the tiles go on.

Right after the old tiles are stripped and the new pipework is laid, the recess is formed in brickwork at a convenient height on the shower wall.

The niche is then plastered, waterproofed along with the rest of the shower enclosure, and tiled inside with a slight forward slope on the bottom shelf so water drains right off.
