Choosing an office water dispenser is a specification decision, not simply a choice of appliance. The right system needs to suit the number of people using it, the water types required, the available space, the incoming water conditions and the way the system will be maintained. For a wider view of workplace requirements, see Sovereign Water’s commercial water solutions.
Last updated: August 2026. This guide is based on Sovereign Water’s experience specifying and maintaining commercial drinking-water systems for UK offices, hospitality venues and workplaces. Final product availability and site suitability should always be confirmed before specification.
TL;DR
- Choose the system around peak demand, water types, available space and servicing, not just headcount.
- Countertop systems can suit visible shared spaces; under-counter taps can preserve worktop space in kitchens and meeting areas.
- BRITA Top Pro, RoyalFlow BCS Smart Tap, ZIP HydroTap G5 Classic Plus, BRITA Extra C-Tap and ZIP HydroTap Celsius Plus each suit different office requirements.
- A site survey should confirm water, power, drainage, CO2 and cupboard-space requirements before a system is selected.

Quick comparison: which type of system suits your office?
| Option | Best suited to | Water types to consider | Installation approach |
|---|---|---|---|
| BRITA Top Pro | Offices needing a countertop dispenser | Chilled, ambient and sparkling configurations | Countertop with supporting equipment below or nearby |
| RoyalFlow BCS Smart Tap | Offices wanting an integrated tap solution | Boiling, chilled, sparkling and ambient configurations | Under-counter system with a dedicated tap |
| ZIP HydroTap G5 Classic Plus | Offices prioritising instant boiling and chilled water | Boiling, chilled and sparkling configurations | Under-bench system with a single tap |
| BRITA Extra C-Tap | Refurbishments where a clear countertop matters | Chilled, sparkling, ambient and hot configurations | Under-counter system with integrated dispense tap |
| ZIP HydroTap Celsius Plus | Sites focused on hot drinks and chilled water | Boiling and chilled configurations | Under-bench system with a single tap |
The table is a starting point, not a substitute for a site survey. Final selection depends on expected peak demand, available services, water treatment requirements and the space around the intended location.
What to assess before choosing
Start with peak demand, not headcount alone
A system that seems adequate for a team of 30 can still struggle if most people use it in the same ten-minute morning window. Consider how many floors, kitchens and meeting areas need water, whether visitors use the same point, and whether hot drinks create a separate demand for boiling water.
For a smaller office, one well-specified dispense point may be enough. Larger workplaces may need higher output, multiple points of dispense or a combination of a kitchen system and a separate meeting-room unit. The right answer comes from the pattern of use rather than a single staff-number rule.
Choose the water types that matter
Chilled and ambient water covers many office needs. Sparkling water can be valuable in client-facing spaces and hospitality settings. Instant boiling water may reduce reliance on kettles in busy staff kitchens. The more functions combined into one system, the more important it is to confirm that the installation space and servicing plan are suitable.
Check the installation conditions early
Mains-fed systems normally need a cold-water connection and electrical supply. Some configurations may also need drainage, ventilation, CO2 storage or sufficient under-counter space. A survey before final specification avoids choosing a system that cannot be installed neatly in the intended location.
Treat filtration and servicing as part of the choice
The system is only as reliable as its maintenance. Filter changes, sanitisation, CO2 management where relevant and system-specific servicing should be planned around the equipment, local water and level of use. A planned maintenance programme helps keep the installed system practical for the facilities team after installation, not only on day one.
Five office water-system options to compare
1. BRITA Top Pro: a flexible countertop dispenser
BRITA Top Pro is a countertop dispenser range for offices that want a visible, accessible drinking-water point. It can suit staff kitchens, shared workspaces, reception areas and hospitality settings where chilled water, ambient water or sparkling water are part of the requirement.
A countertop unit can be a straightforward route where there is suitable surface space and the office wants a familiar dispenser format. It is worth checking the intended location carefully: the system still needs the necessary water, power and supporting equipment arrangement.
For teams comparing countertop equipment, the key questions are output at busy periods, the number of water types needed, surface space and how the surrounding area will be kept clear and easy to use.
2. RoyalFlow BCS Smart Tap: an integrated office tap
RoyalFlow BCS Smart Tap is Sovereign Water’s own integrated drinking-water tap range. It is suited to offices looking for a tap-led solution rather than a standalone countertop dispenser, particularly where the fit-out calls for a clean and coordinated kitchen or breakout area.
The configuration should reflect the intended water types and the expected demand. In a smaller office, the priority may be chilled and ambient water. In a larger or more amenity-led workplace, boiling and sparkling options may be relevant too.
An under-counter tap system works best when it is planned into the kitchen layout early. Cupboard space, service access, water and power all need to be considered alongside the visible tap finish.
3. ZIP HydroTap G5 Classic Plus: boiling and chilled water at one point
ZIP HydroTap G5 Classic Plus is an under-bench system for workplaces that want instant boiling water alongside chilled drinking water. It can be a strong fit for staff kitchens, meeting areas and office hospitality spaces where hot drinks are used throughout the day.
Its value is in consolidation: one tap can serve water for drinking and hot drinks without relying on a separate kettle at the same point. Whether this is the right choice depends on daily usage, the need for sparkling water, the available under-bench space and the servicing requirements.
For an office that uses hot drinks heavily, assess not only the number of users but also how concentrated that demand is. A busy morning or meeting schedule can affect the right specification.
4. BRITA Extra C-Tap: a clear-countertop option
BRITA Extra C-Tap is an integrated under-counter system for workplaces where preserving worktop space is important. The visible element is the dispense tap, with supporting equipment located below the counter.
This format can suit office refurbishment projects, boardroom pantries and kitchens where the design brief calls for fewer visible appliances. It is also useful where a countertop dispenser would interrupt the layout or compete with other equipment.
Before selecting an under-counter system, confirm the cupboard dimensions, access for future servicing, pipework route and the final position of the tap. These practical details matter as much as the visible design.
5. ZIP HydroTap Celsius Plus: focused on hot drinks and chilled water
ZIP HydroTap Celsius Plus is for offices where instant boiling water and chilled drinking water are the priority, without necessarily requiring sparkling water. It can suit sites where staff-kitchen use is high and a simple, integrated water point is preferred.
The right configuration depends on the office’s use pattern. A system supporting a small team with occasional hot-drink demand is a different proposition from one serving a large floor at peak times. A survey can establish the services and output required for the intended location.
Mains-fed systems compared with bottled coolers
For many permanent office locations, a mains-fed system can reduce the storage and delivery handling associated with bottled water. It connects to the site water supply and can provide a fixed drinking-water point where people work. For a deeper comparison of the operational trade-offs, read Sovereign Water’s mains-fed versus bottled water cooler guide.
Bottled coolers can still be appropriate for temporary locations, sites with limited plumbing access or spaces where a mains connection is not practical. The decision should account for the lease length, access to services, expected use and the treatment required for the incoming water.
A useful comparison looks beyond the initial equipment choice. Consider space, installation work, routine servicing, consumables and how the system will be managed across the life of the workplace.
A practical specification checklist
Before requesting a final recommendation, prepare:
- approximate staff numbers and peak-use periods
- the rooms or floors that need access to drinking water
- required water types: chilled, ambient, sparkling and/or boiling
- photos or drawings of the proposed location
- known water, power, drainage and cupboard-space constraints
- any hospitality, client-facing or accessibility requirements
- the preferred servicing arrangement and who will manage access
This makes the initial discussion more useful and helps identify whether one system or multiple dispense points are appropriate.
