A reliable sink unit is one of the foundations of an efficient professional kitchen. Whether you are washing cookware, rinsing utensils or organising a dedicated pot-wash area, the right unit needs to combine generous washing space with a robust, easy-to-maintain construction.

At expondo, you can choose from professional sink units by Royal Catering designed for restaurants, cafés, takeaways, pizzerias, canteens and other catering environments. The range includes compact single-basin models, larger kitchen sink units with one or two basins, and a three-compartment commercial sink for workflows that require several separate washing stages.

With sizes ranging from compact 60 x 60 cm models to units up to 180 cm wide, there are options for both space-conscious kitchens and larger washing areas. The assortment also includes different depths, basin dimensions and working layouts, making it easier to select a commercial sink unit that fits the available space and the volume of washing carried out each day.

Why choose a stainless steel sink unit?

Stainless steel is particularly well suited to busy catering environments. A stainless steel sink unit provides a durable working surface that is resistant to corrosion, simple to clean and suitable for repeated contact with water throughout the working day.

The smooth construction also makes everyday maintenance straightforward. Splashes, food residue and cleaning products can be removed easily, helping staff keep the wash area clean between tasks. Its neutral silver finish coordinates naturally with other professional catering furniture, so a stainless steel kitchen sink unit can be integrated into both new kitchen installations and existing workspaces.

Royal Catering sink units in the expondo range are designed as freestanding pieces of catering furniture rather than domestic inset sinks. This makes them particularly practical wherever you need a complete washing station without building the basin into a conventional kitchen worktop.

Single, double or three-compartment sink unit?

The number of basins is one of the most important considerations when choosing a sink.

A single sink unit is a practical solution for smaller catering businesses, secondary washing stations and kitchens where available floor space is limited. Compact 60 x 60 cm and 70 x 70 cm models are available alongside wider single-basin units measuring 100, 120, 140 or 160 cm across. A larger worktop gives you additional space around the basin for handling cookware or placing items before and after washing.

For higher washing volumes, a stainless steel double sink unit allows different stages of the cleaning process to take place side by side. One basin can, for example, be used for washing while the second is kept available for rinsing. expondo offers double-basin designs in several footprints, including 140, 160 and 180 cm-wide configurations, so you can match the capacity of your washing station to the available kitchen space.

The range also includes a compact three-compartment commercial sink measuring 100 x 50 cm. Its three 35 x 25 x 25 cm basins provide separate areas that can support multi-stage washing and rinsing routines while keeping the overall footprint relatively compact.

Choose the right size for your commercial sink unit

Overall dimensions matter, but they should not be the only measurement you check. Before ordering a commercial kitchen sink unit, consider the size and depth of the basin as well as the external dimensions of the complete unit.

If you routinely wash large pans, stockpots, trays or grill components, a larger or deeper bowl can make daily work considerably easier. For example, selected Royal Catering models feature basins around 40 to 50 cm wide and approximately 25 to 30 cm deep. Other models prioritise extra worktop or draining space alongside the bowl.

Measure the planned installation area carefully and leave sufficient room for staff to work comfortably around the sink. You should also check the position of existing water connections and drainage and compare them with the technical details of the individual product.

A compact freestanding sink unit can work well in smaller prep rooms, cafés and mobile or restricted catering spaces, while wider 140 to 180 cm models are better suited to demanding pot-wash areas and busy restaurant kitchens.

Practical features for efficient everyday washing

A professional sink needs to do more than simply hold water. Details that seem small can make a significant difference when the equipment is used repeatedly throughout the day.

Selected Royal Catering sink units include a raised rear upstand or splash guard. This helps protect the wall behind the unit from water splashes and makes the surrounding washing area easier to maintain. Depending on the model, the rear edge is approximately 10 to 12 cm high.

Height-adjustable feet are another useful feature found across the range. They help stabilise the free standing kitchen sink unit when the kitchen floor is not perfectly level, while adjustment varies according to the individual model.

Some sink units also provide a lower shelf for storing frequently used items underneath the washing area. On double-basin models, an integrated draining area provides a convenient place for cleaned crockery or equipment before it is returned to service.

Always check the individual product specification to see exactly what is supplied. Fittings and tap configurations vary between models, and taps are not included with every unit.

Create a coordinated professional kitchen

A sink works best when it forms part of a well-planned workflow. Position the washing area so that dirty equipment can arrive without crossing clean preparation zones and so that washed items can be drained, dried and returned to storage efficiently.

If you need enclosed storage beneath your washing area rather than an open-frame sink, explore expondo's sink cabinets. They provide an alternative solution when you want to combine washing facilities with enclosed under-counter space.

For food preparation, plating and equipment organisation, matching stainless steel tables make it easier to create a consistent professional workspace alongside your sink unit.

You can also complete a catering setup with suitable commercial refrigeration for storing chilled and frozen ingredients. Combining washing, preparation and refrigeration equipment according to the flow of your kitchen can reduce unnecessary movement and make daily service more efficient.

Who are stainless steel sink units suitable for?

These industrial sink unit and commercial kitchen designs are primarily intended for professional environments where durability and straightforward cleaning are important. Typical applications include restaurant kitchens, cafés, pubs, takeaways, bakeries, pizzerias, catering businesses, canteens and food-production areas.

They can also be useful outside traditional hospitality settings. Selected sink units are suitable for laboratories, workshops and other professional facilities that require a durable freestanding washing station.

For food businesses, remember that one general-purpose sink may not cover every hygiene requirement. Plan your washing facilities according to how food, equipment and hands need to be washed in your particular premises, and check the applicable requirements when fitting out a new professional kitchen.

What should you check before buying a sink unit?

Start with the space available in the room. Compare the width, depth and total height of the sink with your planned installation point, remembering to allow access for plumbing and enough working space for staff.

Next, consider washing volume. A small operation may only need one generously sized bowl, whereas a busy restaurant may benefit from two basins so washing and rinsing can take place independently. A three-compartment unit can provide further separation when your working process involves multiple washing stages.

Basin dimensions are just as important as the external size. Think about the largest items that will regularly go into the sink. Deep pots and bulky cookware require different capacity from cups, plates or small preparation tools.

You should also compare features such as a rear splash guard, draining area, lower storage shelf, adjustable feet and the fittings supplied with the unit. Checking these details before purchase helps you choose a commercial sink unit that suits your workflow rather than simply selecting by width alone.

Why buy sink units from expondo?

The expondo range gives professional buyers several configurations to choose from rather than limiting the category to one standard design. Royal Catering sink units are available with one, two or three basins and in numerous widths and depths, allowing businesses to select equipment according to kitchen size and washing volume.

Many models combine the basin with features such as adjustable feet, rear splash protection, draining space or a lower shelf. Detailed product pages provide technical dimensions and basin measurements so you can compare models before ordering.

Selected products are also available with quantity-based discounts, which can be useful when furnishing several washing stations or fitting out more than one location. The category displays free delivery and expondo's lowest-price guarantee on eligible products, while technical manuals and spare-parts information are available for supported models.

Whether you need a compact sink unit, a larger commercial kitchen sink unit, a stainless steel double sink unit or a spacious professional washing station, compare the dimensions, basin arrangement and features of the Royal Catering models available at expondo to find the right fit for your kitchen.
