Choosing the right behind-the-mirror system
01 September 2026
DUDLEY INDUSTRIES has produced advice on the key considerations when choosing between bespoke and integrated behind-the-mirror dispensing systems for modern washrooms.

Behind-the-mirror dispensing systems are becoming an increasingly popular option for modern washrooms, helping designers create clean, uncluttered spaces without compromising access to essential hand hygiene facilities.
By housing soap, paper towels and hand-drying equipment within a cabinet behind the mirror, these systems make effective use of the often-underused space above the basin. But with different approaches available, choosing the right system requires more consideration than simply deciding whether concealed dispensing is suitable.
The key questions are how the washroom is being constructed, whether the cabinetry is bespoke or supplied as part of the system, and how the installation will be serviced once the washroom is operational.
Two options illustrate the different approaches particularly well: Classic Behind the Mirror and Modulo Slimline Behind the Mirror.
Bespoke flexibility
Classic Behind the Mirror is designed around individual dispenser units that are incorporated into bespoke cabinetry.
This approach gives washroom contractors and design teams greater freedom over the cabinet itself. The cabinetry can be designed and constructed specifically for the dimensions, layout and aesthetic requirements of the project, with the dispensing units then integrated into the finished installation.
The range includes individual brushed stainless-steel units, including touchless soap dispensers and a pull-down paper towel dispenser.
For projects where bespoke cabinetry is already part of the wider washroom fit-out, this can provide considerable flexibility. Rather than adapting the washroom to accommodate a standard cabinet, the cabinetry can be designed around the space, with the dispensing equipment incorporated into the overall design.
Technical drawings and design support can also help contractors plan the installation and ensure that the cabinet and dispensers work together effectively.
An integrated alternative
Modulo Slimline takes a different approach, providing a ready-made cabinet that can be configured with compatible dispensing equipment.
Available in 600mm and 1200mm widths and with a depth of 230mm, the cabinets are designed to provide a coordinated behind-the-mirror solution without the need to construct the cabinet from scratch.
Multiple cabinets can be installed side by side, making the system suitable for longer runs above banks of basins. Where the available space does not correspond exactly with the cabinet dimensions, mirrored filler cabinets can be used to close gaps and create a more continuous appearance.
Installation is also designed around a straightforward process. Once the wall bracket is fixed, the cabinet can be hung in place and the selected dispensers positioned within it.
The internal configuration provides flexibility over dispenser positioning, allowing the system to be adapted to the requirements of the washroom.
Servicing needs to be considered
While appearance and installation are important, servicing should not be overlooked.
A behind-the-mirror system needs to provide convenient access to consumables and equipment for cleaning and facilities teams. If replenishment is difficult, even a well-designed installation can become inefficient to operate.
The two systems take different approaches.
With Classic Behind the Mirror, consumables can be replenished from below. Depending on the dispenser, pull-down mechanisms or a spring-loaded paper dispenser door allow supplies to be accessed without opening the main cabinetry.
Modulo Slimline provides access by opening the mirrored door. This gives direct access to the dispensing equipment and also provides additional internal storage space.
Both approaches are intended to keep the dispensing equipment concealed while allowing routine servicing to be carried out efficiently.
The preferred option will ultimately depend on the way the cabinet is installed and how the facilities team expects to access and maintain the equipment.
What about multiple basins?
For larger washrooms, the ability to create a continuous dispensing installation can be an important consideration.
Modulo Slimline allows multiple cabinets to be mounted together, providing a practical solution for washrooms with several basins arranged in a row.
The modular approach can help create a consistent visual appearance while providing dispensing facilities at the required points along the basin run.
Classic, by contrast, offers greater freedom where the cabinetry itself is being designed and built specifically for the project. This can be advantageous where the basin arrangement, wall dimensions or architectural design calls for a non-standard solution.
Choosing according to the project
Ultimately, there is no universal answer when it comes to selecting a behind-the-mirror system.
Classic Behind the Mirror is likely to be the better fit where bespoke cabinetry is central to the project and the design team requires flexibility over cabinet dimensions, construction and layout.
Modulo Slimline is more suited to projects where a ready-made cabinet and dispensing system are required as an integrated solution, particularly where multiple cabinets are needed to serve a longer run of basins.
The choice should also take account of the people who will be responsible for maintaining the washroom. Considering how dispensers will be replenished, how easily equipment can be accessed and where consumables will be stored can help prevent servicing issues further down the line.
Looking beyond aesthetics
Concealed dispensing can undoubtedly contribute to a more streamlined washroom design, but aesthetics should not be the only consideration.
The most effective solution is one that combines the desired appearance with practical installation, reliable dispensing and straightforward maintenance.
For specifiers and contractors, that means considering the entire lifecycle of the installation – from how the cabinetry is constructed and the dispensers positioned, through to how the facilities team will service the system day after day.
Whether the project calls for the flexibility of bespoke cabinetry or the convenience of an integrated cabinet solution, the fundamental objective remains the same: to provide accessible hand hygiene facilities while making efficient use of the space above the basin.
Choosing the system at the design stage, with installation and servicing requirements considered alongside aesthetics, can help ensure that the finished washroom performs as well as it looks.
