Planning the sink area: What really matters for the sink and faucet

The sink area is a central workstation in the kitchen. Careful selection of the sink and faucet is crucial for functional and ergonomic workflows. This guide provides a technical overview of available materials, designs, and technologies as a basis for decision-making.

1. Bowl configuration: shape and size

The choice of bowl configuration should be based on individual usage habits.

• Single bowl: This option is suitable for households that primarily use a dishwasher. Large single bowls allow for easy cleaning of bulky dishes such as baking trays or roasters.
• Double bowl: Two usually equally sized basins allow parallel work processes, such as washing in one basin and food preparation in the other. This configuration takes up more space on the countertop.
• 1.5 bowl sink: Combines a main basin with a smaller auxiliary basin. The additional basin is practical for draining liquids or washing food without blocking the main basin.
• Butler sink: A solid basin, often made of ceramic, with a visible front apron. It is a key design element in country-style kitchens. The large volume and forward position can improve ergonomics. It requires specific installation planning and often a reinforced base cabinet.

2. Material choice: Properties of the kitchen sink compared

Each material has specific technical properties.

• Stainless steel: Robust, heat-resistant, and hygienic due to a pore-free surface. Prone to scratches that develop a patina over time. Material thickness and integrated soundproofing mats are quality features.
• Granite composite material: Consists of about 80% quartz sand and 20% acrylic resin. The result is a very hard and scratch-resistant surface available in a wide range of colors. Visible lime deposits can form with dark colors and lime-containing water.
• Ceramic: An extremely hard, sealed glaze is created through a firing process. Ceramic is cut-resistant, scratch-resistant, and heat-resistant. However, the material is brittle, so hard impacts can cause chipping.
• Mineral composite: Allows seamless, joint-free installation into a countertop made of the same material. The material is pore-free and can be repaired by specialists. However, heat and scratch resistance are lower than with ceramic or granite.

3. Types of Sink Installation

The type of installation affects the appearance and cleaning comfort.

• Drop-in sink: The sink is inserted from above. The resting rim can make cleaning more difficult.
• Undermount sink: The basin is attached from below to a waterproof countertop (e.g. stone). This offers high cleaning comfort as dirt can be wiped directly into the basin.
• Flush-mounted sink: An exact milling in the countertop creates an absolutely level transition. This is the most complex and costly installation type.

4. Kitchen faucets: functions and technologies

• High pressure vs. low pressure: The choice is a technical necessity. A high-pressure faucet is needed with central hot water supply. A low-pressure faucet is mandatory when using an under-sink boiler.
• Important functions: A high spout makes filling large pots easier. Modern single-lever mixers use durable ceramic cartridges for precise control.
• Pull-out hose spray: Extends the range of action and makes cleaning the basin easier.
• System faucets: There are systems with additional functions such as dispensing 100 °C hot water, filtered water, or chilled and carbonated water.
• Sensor faucets: Enable touchless operation and increase hygiene.
• Pre-window faucets: For sinks in front of windows, there are foldable, retractable, or removable models to allow the window to be opened.

5. The sink center: accessories and functionality

Accessories can expand the sink into a functional work area. Many systems offer an integrated step in the basin rim. This allows the use of sliding cutting boards, hanging functional bowls, or drip grids on different levels.

Conclusion and key questions for your planning

Careful planning of the sink area is a long-term investment in user comfort. The following questions can help with the decision:

1. What are my dishwashing habits? (Primarily hand washing or dishwasher?) This influences the choice between single, double, or 1.5 basins.
2. How important is the maintenance effort? (e.g. with hard, lime-containing water?) This is a criterion for material and color selection.
3. What material is my countertop made of? This determines the possible installation types (undermount and flush-mounted require waterproof panels).
4. Which additional faucet functions provide real added value for my daily life? (e.g. boiling water, filter function).
5. Is the sink area located in front of a window? If yes, a special pre-window faucet is necessary.
