A floor drain—also known as a floor inlet—is a key component of modern drainage systems and is available in a wide range of designs. It ensures the safe drainage of water, protecting buildings against moisture damage, mold growth, and flooding. Whether in a private bathroom, a walk-in shower, a basement, garage, or laundry room, or in commercial and industrial settings, a high-quality floor or bathroom drain guarantees reliable and efficient water drainage over the long term. 

Thanks to modern materials, innovative technology, and attractive designs, today’s floor drains do more than just meet functional requirements; they also enhance the room's aesthetics and hygiene. Elegant floor and shower drains are becoming increasingly important, particularly in accessible bathroom design. 

A floor drain allows you to customize your shower exactly to your liking. Floor drains—often referred to as "point drains"—are compact drainage units typically installed in the center of the shower area. The surrounding tiles are sloped toward this unit. It is also important to select a drain with a drainage capacity that matches the flow rate of the shower fixture. 

What is a floor drain? 

A floor drain is a drainage component installed in the floor to ensure reliable water removal. Its function is to collect surface water—as well as spray, cleaning water, or wastewater—and channel it in a controlled manner into the sewage system. 

A floor drain typically consists of several components:

• Drain body or base unit 
• Odor trap (siphon) 
• Drain grate or designer cover 
• Bonding flange 
• Top section or extension piece for adjusting to the installation height 
• Connection to the waste pipe 
• Optional debris trap or hair strainer 

The integrated odor trap prevents unpleasant odors from the sewer system from entering the interior space.

Areas of application for floor drains

Bathrooms

Especially in modern, floor-level showers, shower and bathroom drains form the foundation for convenient and elegant drainage. They enable barrier-free access and contribute to a minimalist design.

Basements

Large volumes of water can accumulate in basements due to washing machines, heating systems, or heavy rainfall. A basement drain helps to quickly channel away moisture and prevent water damage. In areas at particular risk, a basement drain equipped with a backflow preventer can offer extra protection; this valve stops sewage from backing up from the sewer system into the building.

Laundry rooms

Water leaking from washing machines or dryers can cause significant damage. A floor drain provides an extra layer of safety.

Garages

Rainwater, snow, or meltwater from vehicles ends up on the floor in garages. Floor drains prevent water from pooling.

Boiler rooms

Boiler rooms also benefit from floor drains, which allow any escaping water to be drained away quickly.

Commercial sector

Restaurants, hotels, commercial kitchens, and food processing facilities are subject to strict hygiene standards; floor drains make it easy to clean the floors.

Industry

Production halls, workshops, and warehouses require robust floor drains capable of withstanding heavy loads and handling high drainage volumes.

Floor drain materials

The choice of material affects durability, hygiene, and load-bearing capacity.

Stainless steel

Stainless steel covers are particularly popular.

Advantages:

• rust-proof
• hygienic
• durable
• easy to maintain
• modern design
• high load-bearing capacity

Plastic

Plastic grates are frequently used in residential construction. Many plastic grates are made of high-quality polypropylene (PP). Polypropylene is characterized by its high resistance to moisture, various chemicals, and corrosion. Floor drains made of plastic or polypropylene are lightweight, durable, and suitable for both residential and commercial applications.

Advantages:

• cost-effective
• lightweight
• corrosion-resistant
• easy to install

Cast iron

Cast iron drains are primarily used in commercial and industrial settings.

Advantages:

• extremely robust
• high load-bearing capacity
• durable

Floor drain or shower channel?

Many homeowners wonder whether a classic floor drain or a shower channel is the better choice.

A floor drain is particularly suitable for:

• smaller showers
• basements
• utility rooms
• garages

A shower channel offers advantages for:

• large showers
• modern bathrooms
• barrier-free showers
• exclusive bathroom designs

Both shower channels and many floor drains (or point drains) are available today with tileable covers, allowing for a particularly harmonious bathroom design.

Designer Floor Drains

Designer drains often feature high-quality stainless steel grates or even tileable covers; these not only ensure reliable drainage but also integrate visually and harmoniously into modern bathrooms. A stainless steel grate for floor drains stands out due to its high corrosion resistance, hygienic surface, and long service life.

The Right Drainage Capacity

A floor drain must be capable of handling a sufficient volume of water.

Important factors:

• size of the shower
• rain shower vs. standard showerhead
• water flow rate per minute
• floor slope
• installation depth of the floor drain

If the drainage capacity is too low, water can back up.

Odor Trap

A high-quality odor trap prevents unpleasant odors from the drainage system and ensures that sewer gases do not enter the room. The water seal within the drain acts as a reliable barrier against unpleasant odors. An important technical specification here is the water seal depth; this refers to the height of the water column in the trap and ensures that sewer gases are reliably blocked. Depending on the floor drain design, the water seal depth can vary and should be appropriate for the specific area of ​​application. Modern systems often feature:

• removable traps
• self-cleaning designs
• odor barriers
• easily accessible cleaning units

Floor drains for accessible bathrooms

Barrier-free showers are a standard feature of modern residential construction.

Floor drains enable:

• curb-free showers
• easy cleaning
• greater comfort
• age-appropriate living
• modern design

Cleaning and maintenance

To ensure floor drains function reliably over the long term, they should be cleaned regularly.

Recommended steps:

• remove the grate
• clean the hair strainer
• rinse out the trap
• remove debris
• check the odor trap

Common causes of clogged floor drains

Typical contamination is caused by:

• hair
• Soap residue
• Lime
• Fat
• Sand
• dust
• Dirt
• Regular maintenance significantly extends the service life.

Advantages of high-quality floor drains

A modern floor drain offers numerous advantages:

• reliable drainage
• Protection against water damage
• hygienic cleaning
• durable materials
• modern design
• easy maintenance
• high resilience
• secure odor seal
• versatile uses

Stainless steel floor drains

Stainless steel is the perfect material for floor drains. On the one hand it is easy to care for, on the other hand it impresses with its high robustness and is corrosion and temperature resistant.

Flat installation of floor drains

Floor drains can be installed completely at ground level in the drain area - barrier-free access is welcome. In addition, floor drains are available in many shapes, which in turn provides even greater freedom of design.

Proper sealing of the floor drain permanently protects the building from moisture damage. A secure connection between the floor drain and the sealing system is crucial, especially in wet rooms such as bathrooms and floor-level showers. Sealing flanges or adhesive flanges are often used here, which enable reliable integration into the composite seal.

Floor drains and tiles

Floor drains and tiles belong together – that’s clear. Because a floor drain only comes into its own when surrounded by tiles, and in this case it really makes a difference. There is also the choice between a vertical or horizontal floor drain. Depending on the orientation, the water pipe either runs vertically into the ground or is routed horizontally using a round.

Buying advice: What should you pay attention to?

Several factors play a role when purchasing.

Important criteria:

• material
• Drain performance
• Installation depth: The installation depth should always match the existing floor structure. Floor drains with a shallow installation depth are suitable for renovations or shallow shower areas, while new buildings often have more scope for design.
• Load class (the load class of the floor drain must match the planned area of use)
• Odor trap (siphon) with defined sealing water height
• Cleaning options
• Design & Cover: If you prefer a particularly subtle look, you can choose a tileable floor drain with a tile insert.
• Sealing
• Compliance with standards: High-quality floor drains should comply with the relevant DIN and EN standards and be suitable for the respective area of application.
• Spare parts availability
• Nozzle inclination and drain direction: Depending on the installation situation, attention should be paid to a horizontal or vertical drain nozzle and the appropriate nozzle inclination.
