Contoured door grips: kitchen design and ergonomics with Sinua

Kitchens are increasingly going handleless. But which opening systems should you choose? Must they be flat, 30° or “L”-shaped recessed handle profiles, which look modern but can feel a little cold and may be difficult to grip with wet or greasy hands? A contoured door grip is the design-led answer. Arredo3 presents Sinua.

Contoured door grips in the kitchen

Handleless kitchens offer opening systems such as the classic flat recessed handle profile, the 30-degree angled version or the “L”-shaped option. Extremely minimalist and perfect for a clean-lined design, they may be less ergonomic for those who love cooking and use their kitchen intensively. Going back to handles is not the answer for those who dislike them. There is room for other possibilities, which Arredo3 explores with Sinua.

Sinua creates more room to grip, making opening easier and more secure without disrupting the minimalist look. It combines a recessed handle profile with a recess machined into the door. This creates a wave-shaped contour with a sculptural, distinctive character.

Sinua for a kitchen with integrated door grips

1. Il design 

The Sinua door grip features clean yet sinuous lines, thanks to a contoured door edge that gives the panel's profile an almost soft curve. It is paired with a recessed handle profile to maintain a clean-lined, handleless design and is exclusive to Time, Arredo3's collection of modern, colourful lacquered kitchens.

2. Ergonomics

The shaped edge of the door with the Sinua grip, combined with the recessed handle profile, makes the unit easy and comfortable to use. There is plenty of room to insert your fingers to open it and a generous surface to grip. The contoured recess also protects the edge from mechanical wear.

3. Variants

The Sinua contoured grip can be used both horizontally and vertically. It can therefore run along the top edge of fronts on base units and all their modules, including corner units, deep drawers and drawers, or along the right- or left-hand side of tall unit doors, starting from the top or bottom. It is then paired with a recessed handle profile, available in a colour that matches the door finish or contrasts with it to create a bold decorative effect.

A kitchen with integrated door grips enhances the sophistication of minimalist layouts with the appeal of recessed handle profiles, while offering the practical ergonomics of handles.

Preguntas y respuestas sobre el uñero perfilado

What is a contoured door grip, and how does it differ from a simple straight recessed handle profile? 

A contoured door grip is machined directly into the thickness of the panel so the cabinet can be opened without external handles. Unlike a traditional straight recessed handle system, which consists of an “L”-shaped recess in the cabinet carcass hidden behind the front panel, a contoured door grip makes its shape clearly visible. This is the case with Sinua by Arredo3, which has a sinuous, wave-like contour. This shape combines a larger, ergonomic contact surface for the fingers with a distinctive visual feature that enhances the kitchen front. In general, a contoured door grip is one of the different types of opening systems used for kitchen doors.

What is the difference between a recessed handle profile and a door grip?

A recessed handle system consists of a recess in the carcass: at the top for base units, at the bottom for wall units and at the side for tall units. The surface is then lined with a metal profile, which can be chosen to match or contrast with the rest of the kitchen. The corresponding front panel, on the other hand, can remain as it is, because the recess extends above it, leaving the space needed to insert your fingers and open the unit. Alternatively, the panel can be machined, usually both to provide a better grip and to give the piece a more refined appearance. To visualise these differences, see the Arredo3 guide to opening systems.
The door grip, by contrast, takes machining of the front panel a step further: to make the grip even more ergonomic and easier to pull towards you, the front panel itself is also recessed, while the untouched section becomes the perfect grip.
In short, some opening systems use a recessed handle profile on its own, while others combine it with a door grip.

The Sinua contoured kitchen door grip shapes the front panel's profile to soften it, creating clean yet sinuous lines that are practical and comfortable to grip and open.

How do a door grip and a recessed handle system work together?

First of all, the two need to be used together. The recess machined into the door has a natural shape for inserting your fingers, but only the recessed handle profile in the cabinet carcass provides the space they need to reach it. The contoured shape offers an additional grip for pulling the door towards you, making opening easier and smoother than with a classic recessed handle profile.

What practical advantages does the Sinua contoured grip offer over push-pull opening?

Unlike push-pull mechanisms, which are subject to mechanical wear and a build-up of dirt from fingers constantly pressing on the front, the Sinua contoured grip provides direct, quick and immediate mechanical opening of heavy doors and drawers. The absence of built-in moving parts and the smooth shape of the recess also make the surface easy to clean hygienically. Above all, they keep the front edge cleaner: it is not touched and is therefore protected from repeated impacts.

Does the Sinua contoured grip reduce the usable space inside base units and drawers?

No, because the opening system uses the gap created by the standard recessed handle profile, keeping the cabinet's capacity intact. Sinua's machining only affects the thickness at the top of the door, with no profiles protruding either inwards or outwards. As a result, the storage capacity of drawers, deep drawers and compartments in general remains 100% unchanged.

The must-have element: the lightness of glass

The Sinua door grip, with its contoured panel edge, was designed as a feature exclusive to the Time collection of modern, colourful lacquered kitchens. It brings a new sense of movement to a minimalist, clean-lined style through an elegant, understated detail. It introduces a modern decorative feature into the collection's clean lines, adding a sinuous refinement that echoes the trend for soft, welcoming shapes. It complements related solutions such as Arco end panels, whose gentle curves replace the smooth, straight lines of the original design.
