Combination Units

Streamline your commercial washroom with modern combination units designed to save space, reduce clutter and deliver a premium user experience. At John Barnes Group, you can buy combination units online for a wide range of projects across Brisbane, Queensland, New South Wales and Australia-wide. From sleek paper towel and waste units to compact multi-function systems, our range helps you create washrooms that look contemporary, perform reliably and are easy to maintain day after day.

What Are Combination Units and Where Are They Used?

Combination units are multi-function washroom fixtures that combine frequently used elements into a single, compact fitting. Instead of installing separate paper towel dispensers, hand dryers, waste bins or soap dispensers, a combination unit integrates two or more of these into one streamlined design. The result is a cleaner, less cluttered wall surface, better traffic flow and a more modern overall look.

These architectural washroom accessories are ideal for high-traffic amenities where presentation and durability are equally important. You’ll see combination units in:

• Commercial office buildings and fitouts
• Shopping centres and retail developments
• Hotels, hospitality venues and restaurants
• Schools, universities and childcare facilities
• Health, aged care and medical facilities
• Public amenities, transport hubs and recreation centres

Whether you’re working on a premium lobby bathroom or a robust back-of-house staff facility, the right combination unit helps tie your washroom design together alongside your architectural door hardware, front door entry sets and internal door fittings.

Key Benefits of Commercial Combination Units

Space-Saving and Accessible

In busy amenities, every millimetre counts. Combination units reduce the number of individual fixtures on the wall, freeing up valuable space and making it easier for users to move through the washroom. In narrow corridors and compact cubicles, this can make a noticeable difference to comfort and usability.

Clean, Contemporary Aesthetics

A modern washroom should feel calm, uncluttered and easy to navigate. Combination units deliver a neat, integrated look that suits contemporary and premium commercial interiors. Clean lines, minimal joins and a consistent finish help your amenities match the quality of your front door, internal door and external entry hardware throughout the building.

Reduced Maintenance and Vandal Resistance

Fewer separate fittings mean fewer surfaces to damage, clean or replace. Many combination units are designed with commercial use in mind, with robust stainless steel construction, secure access panels and simple internal components that make servicing more efficient. For facility managers across Brisbane, Queensland and New South Wales, this can translate into lower long-term maintenance demands.

Improved Hygiene and User Flow

By grouping drying and waste disposal in one place, combination units help keep traffic flowing in a logical direction and minimise water dripping across the floor. Users dry their hands and dispose of paper towels in the same location, which helps maintain cleanliness and reduces trip hazards caused by excess water in circulation areas.

Combination Units for Different Project Types

Commercial and Public Amenities

For commercial and public projects, performance, durability and compliance are non-negotiable. Our range of combination units is tailored to high-traffic environments where fixtures need to withstand constant use. Paired with trusted architectural door hardware from brands like Dormakaba and Lockwood, these units help create secure, reliable and professional facilities that reflect well on your organisation.

Premium and Design-Led Spaces

In premium office towers, boutique hotels or high-end hospitality venues, the washroom is an extension of your brand. Contemporary combination units with clean profiles and quality finishes complement modern, architectural door hardware and statement front door sets. Coordinate your combination units with matte black, stainless steel or warm brass tones found in Barben and Zanda hardware throughout the project to achieve a cohesive, design-led result.

Education, Health and Aged Care

In schools, universities, hospitals and aged care facilities, functionality and hygiene are key. Combination units suited to these environments help simplify cleaning routines and reduce the risk of fixtures being knocked, damaged or misused. Combined with accessible grab rails, compliant hardware and secure door systems, you can create safe, user-friendly amenities that are easy to supervise and maintain.

Finishes and Styles to Match Your Hardware

Matte Black, Stainless Steel and Brass-Inspired Schemes

Today’s washrooms often mirror the finishes used on front door and internal door hardware throughout the building. While many commercial combination units are supplied in durable satin stainless steel for maximum longevity, they sit comfortably alongside popular colour palettes such as matte black, brushed nickel and brass-inspired tones used in Barben, Dormakaba, Lockwood and Zanda ranges.

If you’re designing a modern, monochrome scheme, stainless steel combination units pair seamlessly with matte black levers, pulls and bathroom accessories. For more classic or premium interiors, the clean metallic finish contrasts elegantly with warm brass door furniture and decorative handles, keeping your washrooms looking refined and considered without compromising on performance.

Surface-Mounted and Recessed Options

Depending on your wall construction, project budget and desired aesthetic, you may choose either surface-mounted or recessed combination units. Surface-mounted units are ideal for retrofits and upgrades, allowing you to buy combination units online and install them with minimal disruption. Recessed options, where suitable, provide a slimline, built-in look that is especially popular in high-end commercial bathrooms and space-conscious projects.

Frequently Asked Questions

What is a combination unit in a commercial bathroom?

A combination unit is a multi-function washroom fixture that integrates two or more common bathroom functions into one fitting, such as a paper towel dispenser with an integrated waste bin, or a unit that combines hand drying, waste disposal and sometimes soap dispensing. This helps save space, create a cleaner aesthetic and simplify maintenance in busy commercial amenities.

Where are combination units most commonly installed?

Combination units are commonly installed in commercial and public washrooms, including office buildings, shopping centres, hospitality venues, schools, universities, hospitals, recreation centres and transport hubs. They are ideal wherever you need durable, low-maintenance fixtures that can handle high traffic while still looking modern and professional.

Can I use combination units in residential bathrooms?

Combination units are primarily designed for commercial and public applications, but they can be used in larger residential or mixed-use projects where a more commercial-style amenity is required, such as apartment building common areas or shared facilities. For typical residential bathrooms, individual towel rails, hooks and smaller accessories are more common, often paired with architectural door hardware from brands like Barben, Dormakaba, Lockwood and Zanda.

How do I choose between surface-mounted and recessed combination units?

The choice depends on your wall construction, available space and desired look. Surface-mounted units are easier to retrofit and are ideal for upgrades where you don’t want to modify existing walls. Recessed units provide a streamlined, built-in appearance but require suitable wall cavities and more planning during construction. If you’re unsure, speak with your builder, installer or the John Barnes Group team for guidance based on your specific project.

What finishes work best with my existing door hardware?

Most commercial combination units are supplied in satin stainless steel, which coordinates well with a wide variety of door hardware finishes. Stainless steel pairs seamlessly with matte black levers and pulls for a modern, contemporary look, and contrasts elegantly with brass or bronze-inspired hardware for a more premium feel. If your project uses brands like Barben, Dormakaba, Lockwood or Zanda, stainless steel combination units generally integrate smoothly with their popular finish ranges.

Are combination units easy to maintain and service?

Yes. Combination units are designed for high-traffic environments, with robust construction and straightforward internal mechanisms. Regular checks to refill paper towels or soap, empty waste containers and clean exposed surfaces are typically all that’s required. Because you’re dealing with one integrated unit instead of multiple separate fittings, overall maintenance can be simpler and more efficient for facility managers.

Can I buy combination units online for projects outside Brisbane or New South Wales?

Absolutely. While John Barnes Group has a strong presence in Brisbane, Queensland and New South Wales, our online store supports customers Australia-wide. You can buy combination units online from anywhere in the country, and our team can assist with product selection, coordination with your architectural door hardware and delivery to your project location.

Do combination units work with both paper towels and hand dryers?

Some combination units are designed exclusively for paper towel dispensing and waste collection, while others integrate additional features, such as hand dryers. When you’re selecting products, review the unit description to ensure it includes the functionality you need. If you’re designing a premium or high-traffic washroom, a combination of paper towel and dryer options may offer the best balance of speed, user preference and hygiene.

How do combination units fit into an overall hardware schedule?

Combination units are usually specified alongside other bathroom hardware and architectural door hardware within a project’s overall schedule. They sit within the washroom section of your documentation, coordinated with door hardware sets, electronic access control, grab rails, mirrors and other fittings. Working with the John Barnes Group team helps ensure your combination units align with the rest of your hardware in terms of finish, function and quality.
