Introduction: Why proper installation matters more than the drain itselfYou can buy the most expensive, high-quality stainless steel shower drain, but if installed incorrectly, all its advantages will be nullified. Leaks, unpleasant odors, standing water, cracked tiles-these are just a few of the problems caused by unqualified installation. As a manufacturer, we want our products to serve reliably for a long time. That is why we have created this comprehensive guide, based on our 15 years of experience and analysis of thousands of installations. This manual is intended for installers, foremen, and private craftsmen who strive to do their job well and avoid rework. We will not only show you how to correctly install a Penetrade drain but also break down the 7 most common and costly mistakes. 1.

Step-by-step installation guide for Penetrade linear drain We have broken the process down into 8 simple, clear steps. Step 1: Positioning and marking Determine where the drain will be placed (against a wall or at the shower entrance). Using a level and tape measure, mark its exact position on the floor. Step 2: Connection to the sewer system Connect the drain body to the sewer pipe (standard diameter 50 mm). Ensure the connection is sealed. The Penetrade drain siphon rotates 360 degrees , greatly simplifying this step. Step 3: Installing the drain body and rough screed Set the drain body perfectly level using the adjustable feet. Pour the rough screed, creating a main slope (1.5-2%) toward the drain. The screed surface should be 2-3 cm below the drain flange.

Apply the first layer of coating waterproofing to the screed and walls (to a height of 20-30 cm). Tape all corners and joints, including the drain flange, with special waterproofing tape. Apply a second layer of waterproofing. Allow to dry completely (24 hours). Step 5: Finish screed Pour the finish screed over the waterproofing, bringing it level with the drain flange. Maintain the slope toward the drain. Step 6: Laying tiles Start laying tiles from the drain toward the walls. Apply tile adhesive and lay the tiles, leaving a 1-2 mm gap between the tile and the drain grate. Step 7: Grouting joints After the adhesive has dried (24-48 hours), grout the joints. For wet areas, we recommend epoxy grout as the most durable and water-resistant option. Step 8: Installing the grate and testing Fit the decorative grate. Gently pour water and ensure it drains completely without forming puddles. [Video: Insert link to installation tutorial on YouTube/VK] 3.
