Floor drains – how they work, and what you need to know


Floor drains – how they work, and what you need to know


Floor drains are an essential part of any wet room, industrial area or commercial building where efficient drainage is necessary. A properly installed floor drain prevents water damage, ensures hygiene and contributes to a long lifespan for the flooring. However, there are many types and solutions – from classic round drains to modern linear drains and specially designed models for industrial environments. In this article, we go through how floor drains work, what you should consider when choosing a model, and which types and manufacturers dominate the market.
The article presents a wide range of floor drains representing different materials, designs and areas of application. The purpose is to provide an overview of the most relevant features and functions so that you can more easily assess which solution best suits your project. The information about the products is based on publicly available descriptions from manufacturers and retailers and is summarised to provide a clear and informative overview.
Factors to consider when buying floor drains
When choosing a floor drain, it is important to take into account both function, capacity and maintenance. Here are some of the most important factors you should consider.
1. Material and durability
Floor drains are typically made of stainless steel, plastic or cast iron. Stainless steel is popular in commercial buildings and industrial environments due to its corrosion resistance and hygienic surface. Plastic drains are lighter and often cheaper but are best suited for less demanding areas.
2. Capacity and drainage performance
The drain’s capacity must match the amount of water expected to flow through the system. In wet rooms with high loads – such as large kitchens, production areas or changing rooms – it is important to choose a drain with high flow and an efficient water trap.
3. Design and placement
The design affects both functionality and aesthetics. Round drains are classic and easy to install, while linear drains provide a more modern look and can be discreetly integrated along the wall. The placement should be carefully planned in relation to the floor slope so that water is effectively directed towards the drain.
4. Cleaning and maintenance
A floor drain must be easy to clean to avoid odours and bacterial growth. Many modern models have removable grates and water traps that make cleaning quick and simple. In commercial environments, it may be advantageous to choose models with self-cleaning functions or removable components.
5. Tightness and installation
Proper installation is crucial to avoid leaks and moisture damage. Ensure that the floor drain is compatible with the floor membrane and complies with current building regulations. Professional installation is recommended, especially in wet rooms and commercial buildings.

Different types of floor drains
There are many types of floor drains that vary in shape, function and area of application. The choice depends on where the drain will be used and what requirements are placed on capacity and design.
1. Point drains
Point drains are the classic solution where water is directed towards a central point. They are easy to install and suitable for bathrooms, basements and smaller wet rooms. Point drains come in many sizes and materials and can be fitted with different grates for a customised look.
2. Linear drains
Linear drains, also called drainage channels, are long and narrow and are typically placed along the wall or in the middle of the floor. They provide a modern appearance and make it easier to create an even slope in the floor. Linear drains are popular in both private bathrooms and larger commercial buildings.
3. Industrial channels and special drains
In production halls, large kitchens and laboratories, larger drainage systems with high capacity and resistance to chemicals and heat are often used. These can be equipped with sand traps, odour barriers and removable grates for easy cleaning.
4. Design drains
Design drains combine functionality with aesthetics. They are available in many shapes and finishes – from brushed steel to tile-insert grates – and can be integrated almost invisibly into the floor. This type is often chosen in modern buildings where details matter.

Frequently asked questions
How does a floor drain work?
A floor drain directs water away from the floor surface and into the drainage system. The water trap prevents odours from the sewer from rising up, while the grate and filter collect larger particles and dirt.
How often should a floor drain be cleaned?
It depends on usage, but as a rule of thumb, the drain should be cleaned at least once a month. In commercial environments with heavy use, weekly cleaning may be necessary to avoid blockages and odours.
Can you install a floor drain yourself?
In smaller projects, the work can be done yourself, but in wet rooms and commercial buildings, installation often needs to be carried out by an authorised plumber to ensure tightness and compliance with building regulations.
What should you do if the floor drain smells?
Odours are typically caused by a dried-out water trap or a build-up of dirt. Pour water into the drain to restore the water trap and clean the drain thoroughly. If problems persist, the installation should be checked.
Which floor drain is best suited for commercial buildings?
In commercial buildings, stainless steel drains with high capacity and easy access for cleaning are recommended. Linear drains or industrial channels are often the most effective solutions in larger rooms with high water consumption.
