Top 6 best water coolers for small offices 2026

Which water cooler is best for a small office?

Without a water connection: the SPA® Fountain compact. It is the only unit without a mains connection that has a price on the site (€18.50 a month or €490 to buy, excluding VAT), with no minimum term and three months' notice. The countertop model is 64 cm high, 31 cm wide and 53 cm deep and needs a 220-volt socket, with a 1.5-metre cable. Delivery, installation, technical support and collection when you cancel are included.

What ends up in the glass: SPA Reine, natural mineral water, chilled to 9 degrees. Nothing else. According to the product page, the SPA® Fountain works only with 10-litre SPA Reine packs, so no sparkling water, no hot water and no 5-litre pack.

With a tap within reach, the choice shifts. A mains-fed unit spends next to nothing per litre on water, and Culligan, BRITA and Aqualex add sparkling or hot water. None of the three publishes a price, though, and PHIL, which does, ties you in for at least five years.

How much water does a small office use per month?

Less than the brochures suggest. We work with 0.75 litres per person per working day at the unit. The EFSA advice (2 litres a day for women, 2.5 litres for men) covers a whole day, at home and on the road included, not what you draw from a unit at the office. The 0.75 litres is our assumption.

With 21 working days: 5 people use 79 litres a month, 8 people 126 litres, 15 people 236 litres. In 10-litre packs that is 8, 13 and 24. Bobex works with a capacity of 0.5 to 1 litre per user per hour; every unit on this list clears that easily. According to its technical sheet, BRITA's Top Compact countertop model chills 22 litres an hour, enough for 5 to 25 users.

Check the first month. Anyone working from home on Tuesday and Friday does not drink from the office unit on those days.

What does a water cooler cost per month for five, eight or fifteen people?

Back to the litre, with the prices we read on 26 October 2026.

SPA® Fountain compact with 10-litre SPA Reine packs (rent €18.50, pack €11.95 from three or €13.49 each at Bruneau, all excluding VAT): 5 people €114 to €126 a month, 8 people €174 to €194, 15 people €305 to €342. Per litre €1.29 to €1.61. Bruneau does list that pack reference as out of stock; the pack in stock shows no price.

PHIL on the mains (rent €50 to €65 excluding VAT, maintenance and filter included, plus the mains water): 5 people €50 to €66 a month, 8 people €51 to €66, 15 people €51 to €67. The rent stays the same, so the bigger the team, the cheaper the litre: €0.83 for five people against €0.28 for fifteen.

A bottle cooler with large bottles, at Bobex's indicative prices (rent around €15 a month for about ten users, water €0.60 to €0.90 per litre, VAT not stated): 5 people €62 to €86, 8 people €91 to €128, 15 people €157 to €228. Those are averages from a quotation platform, not a Culligan price.

Tap water and carafes only: 126 litres cost €0.67 to €1.19 a month at De Watergroep, including 6 percent VAT and the sanitation charges, without the fixed charge. If you do not need chilled water, there is nothing to rent.

Which contract suits an SME?

A short one. In this ranking the contract weighs the most, together with set-up, because a small company moves, grows or shrinks faster than a head office.

In the small print, as stated on the pages:

- SPA® Fountain: no minimum term, cancel at any time with three months' notice, the first two months free. - Culligan bottle coolers: no obligation, stop at any time. For its mains-fed units Culligan speaks of flexible contracts, with no length given. - PHIL: rental and maintenance contracts of at least 60 months, then renewed yearly, and a deposit of three months' rent. Renting is for businesses only. - Aquablu: a contract of 24 to 60, with no unit on the page, most likely months. - BRITA and Aqualex: no term on the page, just a quotation.

At PHIL that means €3,000 to €3,900 of rent over five years, plus a €150 to €195 deposit. At SPA Fountain, stopping costs at most three months of rent, €55.50.

Do you need a water connection?

For four of the six units, yes. PHIL needs a free 3/4-inch outdoor tap and a 230-volt, 16-amp socket; under-counter cooling also needs 200 cm² of natural ventilation. Aqualex connects chilled and sparkling water to the mains. Aquablu connects the unit straight to the mains. BRITA's Top Compact is a mains-fed unit, as a countertop or freestanding model.

Without a connection, two kinds remain. A Culligan bottle cooler works with 11-litre or 19-litre bottles and a plug in the socket. A SPA® Fountain works with 10-litre packs. The difference is in lifting and stacking: a 19-litre bottle weighs almost twice as much as a pack, and 13 packs a month need a spot in a cupboard or storeroom.

Is a cooler with packs better than tap water?

No. It is more expensive and it is a different water. In Flanders, 99.56 percent of drinking water analyses met the standards in 2024, and a carafe of tap water costs eight people under €1.20 a month. You buy or rent a cooler for chilled water at your desk, for a fixed composition if you choose mineral water, or for sparkling water from the tap. Not because the water from the tap falls short.
