Shower Grates

The new way that is described in the latest Australian Standard governing this is to first have the bathroom fully waterproofed by an approved water-proofing contractor and then install your grate tray on top of the membrane over your plumbed drain. Bedding is then built up around the grate tray and the tiled surface is installed right up to the tray edge.

Insert the tip of the screwdriver through an opening in the cover and lift up. For a snap in cover, spray lubricant along the edges of it as well. Let it settle down into the threads. Insert the needle-nose pliers into the openings of the drain cover, firmly grip the pliers, twist it towards the left, and pull it out.

Pour a measure of baking powder down the drain. After waiting a while, pour down an equal amount of vinegar. Watch for hissing as the two substances will react, and (hopefully) break down the rest of whatever is down there. Now let the tap run again to flush it all away.
