When planning a kitchen renovation, one of the first measurements you need to lock down is the vertical space you have to work with. The standard height for Wren kitchen units follows the industry norm for base cabinets, which is designed to accommodate average human ergonomics and standard countertop thickness. Understanding this specific dimension is crucial for ensuring your workflow is comfortable and your layout meets building regulations.
The Standard Base Cabinet Height
The core answer to "what height are Wren kitchen units" lies in the base cabinets, which house the drawers and doors below your countertop. The universally accepted standard for this height is 900mm. This specific measurement provides the ideal balance for food preparation, allowing most adults to work without excessive bending or stretching. Wren’s range is built upon this foundational dimension to ensure compatibility with standard worktops and appliances.
Why 900mm is the Industry Standard
The prevalence of the 900mm base unit is not arbitrary; it is the result of decades of ergonomic research. This height typically aligns with the average elbow height of a person standing upright, which is critical for comfortable cooking. When you add the standard 40mm to 60mm thick worktop slab to the 900mm cabinet height, you land at the common countertop height of 970mm. Wren kitchen units adhere to this formula to deliver a seamless and functional result.

The Role of Worktops and Splashbacks
To fully understand the total vertical space your Wren units will occupy, you must consider the worktop and splashback. The worktop sits directly on the 900mm base cabinet, usually adding another 40mm to 60mm to the overall height. The splashback, which is the vertical panel at the back of the countertop, typically finishes at 600mm or 900mm high, depending on your design choice. This means the combined height from the floor to the bottom of your splashback can be 1500mm or extend fully to the worktop height.
Tall Units and High Installations
While 900mm is the standard for floor-standing bases, Wren kitchen units can be supplied in taller configurations for specific needs. If you are installing against a wall or unit that starts higher off the floor, you might use a 1200mm high cabinet. This is common for pantries or larder units where extra storage height is beneficial without the ergonomic drawbacks of using them for daily food prep. Remember that the countertop will still usually finish at 970mm, so a 1200mm unit would sit above the working surface unless it is a tall storage zone.
Planning for Appliances and Integration
The height of your Wren units must also account for integrating appliances like dishwashers, ovens, and fridges. Built-in dishwashers and ovens are generally designed to fit within an 600mm to 900mm high space, often aligning perfectly with the base cabinet height. When designing your layout, ensure that the cabinetry surrounding these appliances matches the 900mm standard to maintain a cohesive and level appearance throughout your kitchen.

Custom Solutions for Unique Spaces
Not every kitchen is standard, and Wren offers the flexibility to accommodate unusual ceiling heights or design visions. If you have a sloping roof or a specific aesthetic in mind, the base unit height can be adjusted. However, it is vital to maintain the 900mm work triangle for the main run to preserve functionality. Any significant deviation should be discussed with a designer to ensure the structural integrity and usability of the final installation are not compromised.
