Coway Just Made Water the Cheapest Line in Its Rental Book. The Water Cooler Market Should Take Notes

The question I keep putting to operators is simple. What else could you sell to the customer you already visit every month? Coway answered it this week by cutting the price of its water purifiers to help sell beds.

On 31 August the Korean rental company launched a promotion running to 27 October. Any new BEREX rental costs 10,000 won a month for up to 15 months. That is under seven euros. BEREX means beds, mattresses and massage chairs. Alongside it, several home products get 50% off rental for up to 18 months. The list includes two Icon water purifiers, a bidet, a food waste disposer and an induction hob. The water purifier is now a discounted line inside a household subscription. It is no longer the product that subscription is built around.

The number behind the discount

Coway reported its second quarter on 7 August. Revenue rose 14.6% to 1.4422 trillion won. Net rental account additions at home jumped 51.6% year on year to 242,000 in a single quarter. The company credits new categories: wall-mounted air conditioners, food waste disposers and home medical devices.

A water business added a quarter of a million accounts in three months. The growth came from products that are not water. Overseas revenue rose 24.2% to 587.5 billion won, with Malaysia at 434.5 billion won and Thailand up 53.9%. This is not a small experiment in one market.

What Coway is really renting

Coway does not sell a water purifier. It sells a monthly billing relationship, a service visit and a person who turns up. The Cody service network is the asset. That person is in the home every few months. Adding a second product to the same account then costs almost nothing.

The machine is the excuse for the relationship. The relationship is the business. European water dispense operators have the same asset and use one line of it. We build our 31-market database from direct operator interviews and local data partnerships. It shows a typical account carrying one machine and one product line. The route runs, the engineer visits, the invoice goes out, and nothing else moves down that pipe.

Bottled operators have the strongest hand here

Bottled water dispense, or BWD, gets written off as the old model. On this test it is the best placed. A bottled operator sees the customer every two weeks. There is a vehicle, a driver, a delivery note and two minutes of conversation. No plumbed machine gives you a monthly face-to-face contact with the account.

That contact already carries more than water in some markets. Cups, coffee, sanitisation, filters. Western European bottled placements grew 3.4% in 2025. Spain passed a million units on a thirteenth straight year of growth. The delivery round is a distribution channel that a mains-fed rival has to build from scratch.

The part that costs money

Buying accounts this way is not free. Coway's revenue rose 14.6% in the quarter while operating profit rose 4.3%. Cheap entry pricing pulls margin out of year one. It parks the return in years two and three. That only works if the account stays.

So the model rests on retention. The discount is only the door. An operator with high cancellation rates who copies the entry price will buy churn at a loss. An operator with a stable book can lead with a low price. The annuity behind it is real. Your churn rate decides whether this play is smart or reckless. Most operators do not know theirs by cohort.

What this means for POU

Point of use, or POU, means a mains-fed cooler plumbed into the water supply. The install cost is recovered over a long contract. That makes the POU account the most expensive one to win. An account that expensive should be carrying more than one product line.

Coffee is the obvious neighbour and plenty of operators already run it. Beyond that sits sanitisation, filter changes for third-party equipment, air treatment and consumables. None of that needs a new customer. It needs a second item on an invoice the customer already pays.

Where this goes

Watch what happens to Coway's margin over the next two quarters. If operating profit recovers while the account base holds, the multi-category route is proven. Others will copy it. Korean and Malaysian operators are already several years ahead of Europe on this.

For a European operator the first move is a number, before any new product. Work out revenue per account, split by how many lines that account carries. Most operators can tell you their unit count and cannot tell you their revenue per customer. That gap is where the next five years of growth in this market will be won or lost.
