Here is a selection of various shower pan tile installations. With any job there are always unique challenges but with shower pan tile installations the preparation is by far the most important aspect of the installation. When installing pebbles, it is important to create a slope to the drain which is significantly steeper so water drains from in between the pebbles themselves. Due to the nature of pebble mosaics, cups and valleys are typical between stones. Pebble shower pans are popular and take a creative approach to install to hide lines between sheets.
