Before starting to tile the shower area of my wet room, I needed to know how much slope was required for the water to drain properly. So, I searched on the Internet and found that the right slope was between 1.5% and 3%. What????? What does that mean in practical terms??? As I had no idea, I had to work it out another way. My wet room is finished and I am pleased to say that my system works well. So, I would like to share it with you in the hope that you will find useful for your own project!
You need the following: at least 50 cm of plastic (dirt-free) gutter, a level, some shims and a container of water.
Place your section of gutter on a flat surface and pour a small amount of water inside. Put a shim on one side of the gutter and keep adding more shims until the gutter is tilted enough for the water to run freely out of the gutter. Now, take your level, place it inside the gutter and see where exactly the bubble is located on the level. Then, you know for sure what slope you need on your tiles for the water to run into the drain. Make sure you remember that position when you tile your shower floor!
