Floor drains – focus on function, outlet and dimensions


Floor drains – focus on function, outlet and dimensions


A well-functioning floor drain is a crucial part of any wet room solution – both in commercial buildings and private homes. It ensures efficient water drainage, prevents moisture damage, and contributes to a healthy indoor climate. The choice of floor drain depends on several factors such as drain type, dimension, material, and design. In this article, you will get an overview of the most important considerations to make, as well as a presentation of different types and manufacturers on the market.
The article presents a wide range of floor drains, spanning from classic grate drains to modern linear drains in stainless steel. The aim is to provide an informative overview of features, outlet types, and dimensions, so you can more easily assess which solution best suits your project. The product information is based on publicly available descriptions from manufacturers and retailers and is summarised to provide a clear and neutral overview.
Factors to consider when buying floor drains
When choosing a floor drain, it is important to consider both function, installation, and maintenance. Here are some of the most important factors.
1. Drain type and outlet direction
Floor drains are available with vertical or horizontal outlets. The choice depends on the drainage installation under the floor. Vertical outlets are typically used in new builds, while horizontal outlets are often chosen for renovations where the drainpipe lies closer to the floor surface.
2. Dimensions and capacity
The drain’s dimension must match the expected amount of water. In wet rooms with high loads, such as commercial kitchens or changing rooms, you should choose drains with greater capacity. Standard dimensions typically range from 50 to 110 mm, but special solutions exist for industrial purposes.
3. Materials and surfaces
The choice of material affects both durability and aesthetics. Stainless steel is popular for its corrosion resistance and ease of cleaning, while plastic drains are often chosen for their affordability and flexibility. In design-oriented environments, drains with tile inserts can provide a discreet appearance.
4. Cleaning and maintenance
A good drainage system should be easy to clean. Many modern models have removable grates and water traps, making it easy to remove hair and dirt. Also consider models with odour traps, which prevent unpleasant smells from the sewer.
5. Sealing and wet room protection
Proper sealing around the drain is crucial to avoid moisture damage. Ensure that the drain is approved for wet rooms and compatible with the chosen membrane solution. Many manufacturers offer complete systems where floor drains and sealing collars fit together.

Different types of floor drains
Floor drains come in many variants, each with its own advantages depending on the area of use and design requirements.
1. Point drains
Point drains are the classic solution, where water is directed towards a central point in the floor. They are suitable for smaller wet rooms and come in many sizes and materials. This type requires a slope towards the centre of the floor.
2. Linear drains
Linear drains, also called channel drains, are typically placed along the wall or in the middle of the shower area. They provide a modern look and make it easier to create a single-direction slope in the floor. Linear drains are available in both stainless steel and tile insert designs.
3. Corner drains
Corner drains are a discreet solution where the drain is placed in a corner of the room. They are often used in bathrooms where aesthetics and space utilisation are in focus. This type requires precise installation to ensure proper water drainage.
4. Industrial floor drains

Frequently asked questions
Which type of floor drain is best suited for a bathroom?
For standard bathrooms, point drains or linear drains are often chosen. Linear drains provide a modern look and make it easier to create a slope in one direction, while point drains are a classic and flexible solution.
How can you avoid odours from the floor drain?
Odours typically occur if the water trap dries out or becomes blocked. Ensure regular cleaning and choose a drain with an integrated odour trap. In rooms that are rarely used, you can pour a little water into the drain at regular intervals.
Can you install a floor drain yourself?
Installing a floor drain requires precision and knowledge of wet room sealing. It is recommended to have the work carried out by an authorised plumber to ensure proper sealing and compliance with building regulations.
How do you maintain a floor drain?
Clean the grate and water trap regularly to avoid blockages. Remove hair and dirt, and rinse with hot water. Do not use aggressive chemicals, as they can damage the material or seals.
What does the drain’s capacity mean?
The drain’s capacity indicates how much water it can carry away per second. In shower areas with high water volumes, such as with rain showers, you should choose a drain with higher capacity to avoid flooding.
