When hoteliers talk about sustainability, the conversation often circles around the same gestures: towel reuse cards, recycling bins, or swapping out mini toiletries for refillable dispensers.
All well-intentioned, but none of them REALLY shift the numbers on a hotel’s utility bills or environmental footprint.
Meanwhile, the real resource drain continues largely unnoticed: water use in guest showers.
For most hotels, showers are invisible on the balance sheet, but on average, hotel guests use around 340 litres of water per day, with showers responsible for the lion’s share. Heating that water is one of the biggest drains on a hotel’s energy bills. Multiply that by hundreds of rooms, year-round occupancy, and rising utility costs, and you’re looking at tens of thousands of pounds in unnecessary spending every year.
The kind of hidden cost your CFO would notice straight away!
The challenge is only getting bigger
By 2030, global freshwater demand will outpace supply by 40%. Water stress is predicted to put $70 trillion of global GDP at risk, and England alone faces a daily shortfall of 5 billion litres by 2055.
For hotels, that translates into rising bills, tougher regulations, and guests demanding visible sustainability action. Research from Booking.com’s 2025 Sustainable Travel Report shows that 93% of travellers want to travel more sustainably, and many are willing to pay more for certified eco-friendly stays.
The good news? Cutting waste doesn’t mean cutting comfort, it means unlocking five-figure annual savings while strengthening your ESG credentials.
Why showers are overlooked
There’s a reason hotels have been slow to act. Early attempts at water-saving showerheads created poor guest experiences, and the reputational risk of complaints outweighed the potential savings. The industry defaulted to “business as usual.”
At the same time, water consumption often gets bundled into broader utility bills, making it harder for operators to see the specific cost of showers. Out of sight, out of mind.
Today though, technology has caught up and that trade off between savings and comfort is no longer necessary. Many modern showerheads like our Gjosa GS3 Jet-Fusion, deliver a powerful, comfortable shower while using just 4.5 litres 2.0 bar pressure per minute, around a third of the water of a conventional showerhead.
That means up to 65% savings on both water and the energy needed to heat it. And crucially, guests can’t tell the difference.
The sustainability ROI hotels can’t afford to ignore
Sustainability in hospitality has often been seen as a cost centre, something done for optics, guest messaging, or compliance. But water-efficient technology changes that equation. For the first time, hoteliers can deliver meaningful sustainability outcomes with a clear and measurable financial return.
This is the sustainability ROI hotels can’t afford to ignore.
The business case: Water-efficient tech your CFO will love
For hoteliers, the numbers are compelling:
- Utility savings: tens of thousands of pounds annually.
- Quick payback: months, not years.
- Operational benefits: less strain on boilers and pipework, reduced limescale build-up.
- Future-proofing: with ESG reporting requirements on the horizon for 2026, water and energy efficiency will no longer be optional.
At the Best Western Plus in South London, Econovate showerheads were installed across the property. The result? Projected five-figure annual savings, improved EBITDA, and guest satisfaction scores unchanged.
More than just a sustainability gesture
Water efficiency isn’t a token “eco-upgrade”. It’s a financial and operational strategy that directly strengthens margins while delivering measurable environmental benefits.
For hotels, that makes showers one of the smartest investments you can make today. Water-efficient tech your CFO will love, and your guests won’t know the difference!
Showers that pay for themselves. The sustainability ROI no hotel can afford to ignore.
