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. Preparation: Tools and materialsBefore starting, make sure you have everything you need.

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°, 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. Top 7 installation mistakes and how to avoid them Dmitry Frolov, Technical Specialist at Penetrade:“In 10 years, I’ve seen it all. 90% of all drain problems are not product defects but installation errors. Study this list, and you will save yourself and your client a lot of time and money.”
| Mistake | Consequences | How to Avoid |
|---|---|---|
| 1. Incorrect or insufficient slope (<1.5%) | Standing water, puddles, mold growth | Use a level at every stage. Check the slope before pouring the screed. |
| 2. Poor waterproofing (especially around the flange) | Leaks to neighbors below. The most costly mistake. | Use high-quality mastic and tape. Seal the flange in an “envelope” style. |
| 3. No gap between tile and drain | Tile cracks due to pressure from thermal expansion | Leave a 1–2 mm technical gap and fill it with flexible sealant. |
| 4. Incorrect sewer connection | Leaks in the screed, unpleasant odors | Use sealing gaskets. Check tightness before pouring. |
| 5. Concrete poured over drain feet | Impossible to adjust or dismantle later | Feet are for initial positioning only. The main load is carried by the body embedded in the screed. |
| 6. Forgetting to remove protective film from the grate | Film adheres to metal and is extremely hard to remove after renovation | Remove the film immediately after grouting. |
| 7. Wrong choice of tile adhesive or grout | Adhesive peels off from moisture; cement grout washes out and blackens | Only use compounds designed for wet areas and swimming pools. |
