You're Using More Water on Vacation Than You Think — And Some Places Are Running Out

Let's start with a number that might surprise you: the average American uses somewhere between 80 and 100 gallons of water at home per day. Now consider that tourists — staying in hotels, taking longer showers because they're relaxed and unhurried, filling pools, ordering water-intensive meals — typically use two to three times that amount.

In a place with abundant freshwater, that's a statistic. In a place that's running dry, it's a crisis.

And a lot of the places Americans love to travel are, quietly and urgently, running dry.

The Geography of Thirst

The American Southwest is the most obvious example. Arizona, Nevada, New Mexico, and Southern California are all contending with a multi-decade megadrought that climate scientists say is the worst the region has experienced in at least 1,200 years. Lake Mead — the reservoir that supplies water to Las Vegas, Phoenix, and tens of millions of people across the region — hit its lowest recorded level in 2022. It's partially recovered since, but remains dramatically below historical norms.

Las Vegas draws roughly 42 million visitors a year. Those visitors use water. The hotels, casinos, pools, and golf courses they patronize use staggering amounts of water. Nevada has made genuine progress on water recycling — indoor water from the Strip is treated and returned to Lake Mead at a higher rate than almost anywhere else in the country — but the underlying math of a desert city built around tourism and entertainment remains precarious.

The problem isn't unique to the desert. Popular coastal destinations face different but equally serious water challenges. Many Caribbean islands have limited freshwater aquifers that are increasingly threatened by saltwater intrusion as sea levels rise. Parts of coastal Florida are already dealing with this. Hawaii's groundwater systems, which took thousands of years to fill, are being drawn down faster than rainfall can replenish them on some islands.

"Tourism is the economy here," says a water resource manager on a small Caribbean island who spoke with us on background. "But tourism also puts more pressure on our water supply than anything else. We're trying to balance those two realities and it gets harder every year."

How Accommodation Type Changes Everything

Here's where your choices as a traveler actually matter in a measurable way.

Large resort hotels are significant water consumers — not just for guest rooms, but for pools, landscaping, laundry, and food service. A 2019 study published in the Journal of Sustainable Tourism found that resort guests in water-stressed Mediterranean destinations used an average of 440 liters of water per day. That's more than 116 gallons — well above the tourist average, and more than four times what a local resident uses.

Smaller, locally-owned accommodations — including homestays and boutique eco-lodges — tend to use water more like residents do, because in many cases they are residents. They're not maintaining Olympic-sized pools. They're not running industrial laundry operations. They're living in their homes and extending that living to their guests.

"I treat my water the same way whether I have guests or not," says Elena, who hosts travelers in her off-grid adobe home outside Santa Fe. "I have a rainwater collection system and a greywater recycling setup for the garden. My guests learn about it when they arrive, and most of them find it genuinely interesting — it becomes part of the experience."

That kind of embedded water consciousness is hard to replicate at scale. It's one of the things that makes genuine homestays different from hotel experiences dressed up with rustic furniture.

The Shower Conversation Nobody Wants to Have

Okay, let's talk about showers.

Vacation showers are longer than home showers. This is a documented phenomenon and also just... obviously true if you think about it. You're not rushing to get to work. The water pressure might be better than at home. You're unwinding. A standard showerhead flows at about 2 gallons per minute, so the difference between a 7-minute shower and a 15-minute shower is 16 gallons. Multiply that across every guest, every day, at every property in a water-stressed destination, and it adds up fast.

This isn't about shame. It's about awareness. And awareness is the first step toward behavior that actually helps.

Some eco-conscious homestays have found creative ways to make this tangible without being preachy about it. Flow restrictors on showerheads that reduce output to 1.5 gallons per minute. Small cards in the bathroom that explain the local water situation in plain language. Hosts who mention it casually during check-in: "Hey, we're in a drought year, so we appreciate guests keeping showers short — here's what we do."

Guests, when given context rather than just a rule, tend to respond well. People are more willing to change behavior when they understand why it matters.

What to Look for When You're Booking

If water responsibility is something you want to factor into your travel decisions — and in drought-prone destinations, it should be — here's what to look for when you're evaluating accommodations.

Low-flow fixtures. Showerheads, faucets, and toilets that meet WaterSense standards (an EPA certification program) use significantly less water without meaningful sacrifice in performance. Ask hosts directly, or look for it mentioned in the listing.

Greywater and rainwater systems. Properties that recycle water from sinks and showers for garden use, or that collect rainwater for non-drinking uses, are operating with a fundamentally different water footprint. This is more common in eco-conscious homestays than in conventional hotels.

Drought-tolerant landscaping. A property surrounded by native plants that don't need irrigation is making a very different choice than one with a lush green lawn in the middle of a desert. It sounds like a small thing. It isn't.

Transparent communication. Hosts who mention water conservation in their listing — who explain their local context and invite guests into their practices — are signaling a genuine commitment rather than a greenwashed talking point.

No private pool. This one is blunt, but a private pool in a water-stressed destination is a significant luxury with a significant cost. Shared pools, or properties without pools entirely, have a meaningfully smaller water footprint.

The Bigger Picture

Water scarcity is one of the defining environmental challenges of the next several decades, and travel is one of the industries most tangled up in it. The destinations people love most — warm, sunny, visually spectacular, often coastal or desert — tend to be exactly the places where freshwater is most precious and most pressured.

None of this means you shouldn't travel. It means you should travel with your eyes open, with some curiosity about the systems that support your comfort, and with a willingness to make choices that don't extract more than they give.

A shorter shower in a drought-stricken destination won't save a lake. But a traveler who chooses a water-conscious homestay, takes shorter showers, and asks their host about local water challenges is doing something a little more important than conserving water. They're treating the place they're visiting as a real place — one that has to keep existing after they leave.
