How much water does one hotel guest use per night?

Measured at the property boundary, a city hotel typically uses 200-450 litres per occupied room night and a resort 450-1,200 litres. Only about 40-60% of that is used inside the room; the rest is laundry, kitchen, pools, irrigation and losses.

Why is the range so wide?

Climate, pools, irrigated grounds, on-site laundry and food-and-beverage intensity move the figure far more than guest behaviour does. That is why Aquiterum reports a low, likely and high band rather than a single number, and grades how much of your figure came from your own meters.

How does this compare to the Hotel Water Measurement Initiative?

The bands are aligned to the HWMI boundary - water entering the property, normalised per occupied room - so a property already reporting HWMI can compare like for like.

How do I find my own figure?

Divide annual metered consumption in cubic metres by occupied room nights, then multiply by 1,000 to get litres per occupied room night. A free Aquiterum Water Snapshot does this and splits the total across guestrooms, kitchen, laundry, pool, irrigation and unaccounted-for water.

Benchmark

How much water does a hotel room use?

A hotel typically uses 200 to 1,500 litres of water per occupied room night, measured at the property boundary. City hotels sit at the bottom of that range, all-inclusive resorts at the top. The difference is driven by pools, irrigated grounds, on-site laundry and food service - not by guests.

Litres per occupied room night, by property type

These are the bands Aquiterum applies when a property has no meter data of its own. They are aligned to the HWMI boundary so they compare like for like with industry reporting.

Breakdown

Where the water actually goes

The room is rarely the biggest consumer. In a resort, guestrooms account for roughly 40% of demand; the remainder is split between kitchen and food service, laundry, pool top-up and filter backwash, landscape irrigation, cooling systems and unaccounted-for water - the leakage and metering gap that almost every property carries.

That last category matters most. Unaccounted-for water is invisible on an invoice, and it is usually the cheapest volume on the property to recover, because reducing it needs no new plant.

Method

Working out your own figure

Take twelve months of metered supply in cubic metres, divide by occupied room nights over the same period, and multiply by 1,000. That gives litres per occupied room night at the property boundary - the figure you can compare against the bands above.

If your number sits above the high band for your property type, the gap is the interesting part: it is either an unmetered end use, a leak, or an irrigation and pool load that is larger than it looks. A Water Snapshot splits the total and grades how much of the split rests on your data rather than ours.
