Office Water DispenserWith so many options, how do you buy smart, save your company money and avoid a poor investment? This guide walks through the office water dispenser types, compares initial cost, maintenance cost and three-year total cost, and helps you choose the machine that best fits your office.
1. Types of office water dispenser
Bottled-water dispensers
- Use large water bottles that need regular replacement.
- Pros: simple to set up, no plumbing required.
- Cons: bottles need regular changing, and storage space for them.
Countertop dispensers (with a refill tank)
- Description: a compact unit that sits on the counter and is refilled by hand.
- Pros: space-saving, suits small offices, no plumbing required.
- Cons: limited capacity, may need frequent refilling.
Direct-piped to the water supply
Under-sink filter with a dispenser or dedicated tap
- Description: installed under the sink, with a dedicated filtered-water tap.
- Pros: saves counter space, provides a continuous filtered supply, installs out of sight.
- Cons: needs professional installation; water quality depends on the filter's performance.
Table-Top Water Dispenser
- Description: a compact unit that sits on the counter, plumbed directly into the building's water supply.
- Pros: space-saving, suits small offices, no manual refilling.
- Cons: limited capacity, needs professional installation.
Floor Standing Water Dispenser
- Description: a larger unit that stands on the floor, plumbed directly into the building's water supply.
- Pros: unlimited supply, environmentally friendlier, cost-effective long term, large capacity.
- Cons: needs professional installation; water quality depends on the supply system.
Water boiler (supplementary)
- Description: a stainless-steel unit that provides extra hot water, usually alongside the main dispenser.
- Pros: durable, continuous hot-water supply, energy-efficient.
- Cons: utilitarian design, not much to look at.
2. Office size and capacity
Office size
- Small offices: countertop or slimline freestanding dispensers.
- Medium and large offices: higher-capacity freestanding dispensers.
- An under-sink filter plus dispenser combination can be added as an extra configuration
- Bottled-water dispensers: allow storage space for the bottles
Water tank volume
Hot-water demand: make sure the dispenser's hot tank is large enough for the number of staff who take hot drinks.
A water boiler is more often used to provide extra hot water
3. Dispenser features
Water temperature options
- Hot: for tea, coffee and other hot drinks.
- Ambient: room-temperature water for general use.
- Cold: chilled water for refreshment.
Filtration System
- Basic filtration (PP or carbon filters): removes common contaminants and improves taste, but does not remove viruses or bacteria.
- UF ultrafiltration: higher filtration efficiency, removing bacteria and larger particles.
- RO reverse osmosis: the highest level of purification, removing dissolved solids and specific contaminants such as nitrates and heavy metals. Note that RO systems need a drain for waste water. A carbon filter is usually added to refine the RO water's taste.
- Distilled water: removes minerals and contaminants by distillation for the purest water.
- Mineralised water: adds essential minerals after filtration for taste and health benefits, though it may not be the best choice for every use case.

Safety considerations
- Fully boiled water: make sure the dispenser can serve fully boiled hot water as well as cold and ambient.
- Overheat protection: keeps the machine from overheating.
- Hot-water safety lock: keeps hot water safe to dispense.
- Leak protection: prevents damage from leaks.
- Dry-burn protection: stops the machine burning out when empty.
- Earth-leakage protection: keeps the electrics safe.
Electronic panel vs non-electronic controls
- Electronic panel: can include touch-free dispensing; convenient, but may need more maintenance.
- Non-electronic controls: usually more durable, with less to maintain.
Certification
- SGS testing: confirms the dispenser meets stringent health and safety standards.
- NSF certification: indicates compliance with international health and safety standards.
4. Cost considerations
Initial cost vs long-term investment
- Bottled-water dispensers: low initial cost, but the ongoing bottle replacement cost runs high.
- Bottle-free dispensers: higher initial cost, but lower long-term maintenance and supply costs.
Maintenance cost
- One-stop warranty service: look for service that covers on-site filter changes, repairs and maintenance. This is usually more comprehensive for bottle-free dispensers than for bottled ones.
- Scaled to headcount: more users may mean more frequent maintenance and cartridge changes.
Price plans: monthly rental vs purchase
- Monthly rental: flexibility and a lower upfront cost, easier on cash flow. Suits businesses that prefer not to make a large initial investment.
- Purchase: higher upfront cost but better long-term economics. Suits businesses happy to own the equipment and avoid ongoing rental fees.
5. Brand reputation, reviews and customer feedback
- Existing customers: favour brands with a strong customer base and positive feedback.
- Years established: choose brands with a long record of reliability and experience.
6. Other considerations
Sustainability
Your company's own brand reputation: cutting plastic waste aligns the office with corporate sustainability goals.
Appearance and atmosphere
Office look and feel: weigh the office's aesthetics when choosing a dispenser. A modern, well-designed unit complements most interiors and adds a touch of polish to the workplace.
Price analysis
Finally, price remains a major factor. The analysis below runs the numbers for different office sizes, assuming each person drinks 6 cups a day (about 1.5 litres) over a 5-day week, and compares initial cost, ongoing maintenance and three-year total cost across dispenser types.
Example: 15-person office
