Floor drains – technical differences and functions explained


Floor drains – technical differences and functions explained


A well-functioning floor drain is essential for a safe and durable wet room. Whether you are renovating the bathroom, building new, or simply replacing an older drain, there are many technical details to consider. Choice of material, design, capacity, and installation method all play a role in both functionality and aesthetics.
In this article, we go through the most important considerations you should make before choosing a floor drain and provide an overview of different types, features, and manufacturers on the market.
The article presents a wide range of floor drains – from classic point drains to modern linear drains. The aim is to provide an informative overview of features, materials, and design options so you can more easily find the solution that suits your project. The product information is based on publicly available descriptions from manufacturers and retailers and is summarised to provide a neutral and practical basis for comparison.
Factors to consider when buying floor drains
When choosing a floor drain, it is important to consider technical requirements, aesthetics, and maintenance. Here are some of the most important factors to keep in mind.
1. Drain type and placement
The placement and type of drain depend on the layout of the room and the slope of the floor. Point drains are typically placed centrally in the shower area, while linear drains are often installed along the wall for a more minimalist look. Make sure the floor slope directs water efficiently towards the drain regardless of type.
2. Material and durability
Floor drains are most often made of stainless steel, plastic, or composite. Stainless steel is popular for its strength and resistance to corrosion, while plastic drains are lighter and often cheaper. Choose a material that suits both the load and the desired design expression.
3. Water trap and odour protection
An effective water trap prevents odours from the sewage system. Many modern drains have removable water traps, making cleaning easier. In rarely used rooms, a dry or membrane water trap can be an advantage as it does not dry out.
4. Cleaning and maintenance
A drain that is easy to clean extends its lifespan and reduces the risk of clogging. Look for models with removable grates and access to the water trap without tools. Some designs have integrated hair strainers, simplifying daily maintenance.
5. Design and surface
Drains come in many designs – from discreet grates to tile-in solutions where the drain becomes almost invisible. Consider how the drain complements the floor tiles and the style of the room. In modern bathrooms, linear drains with hidden edges are particularly popular.

Different types of floor drains
There are several types of floor drains, each with its own advantages depending on the area of use and design preferences.
1. Point drains
Point drains are the classic solution where water is directed towards a central point. They are easy to install and work well in smaller shower areas. Point drains come in many shapes – round, square, and triangular – and can be adapted to different tile sizes.
2. Linear drains
Linear drains, also called channel drains, provide a modern look and make it easier to create an even slope in the floor. They are typically placed along the wall or by the shower area and come in many lengths and designs. Linear drains are ideal for large tiles and minimalist bathrooms.
3. Corner drains
Corner drains make efficient use of space and are suitable for small bathrooms. They provide a discreet look and can be a practical solution where the floor layout makes a central drain difficult.
4. Special drains

Frequently asked questions
How do I choose the right floor drain?
Start by assessing the size of the room, the slope of the floor, and the type of tiles. Then choose a drain type that suits both function and aesthetics. Linear drains are suitable for large tiles, while point drains work well in smaller areas.
Can I install a floor drain myself?
Installing a floor drain requires precision and knowledge of wet room regulations. It is recommended to have the work carried out by an authorised plumber to ensure proper sealing and slope.
How do I avoid odours from the drain?
Make sure the water trap always contains water and clean the drain regularly. If the drain is rarely used, a membrane water trap can prevent drying out and thus odours.
How often should I clean my floor drain?
It depends on usage, but as a rule of thumb, you should clean the drain at least once a month. Remove hair and soap residue and rinse with hot water to keep the flow optimal.
What does the drain’s capacity mean?
The capacity indicates how much water the drain can handle per second. In shower areas with a high water volume, such as rain showers, you should choose a drain with high capacity to avoid flooding.
