The ROI of Aquariums: Do They Really Pay Off?

Alexander Jiro Nomiya Krause

Aquariums are beautiful, calming, and often the focal point of a space. But in today’s competitive business environment, aesthetics alone don’t cut it. Decision-makers want results — and they’re asking:

Does installing an aquarium make financial sense?

The answer is becoming increasingly clear: Yes. When used strategically, aquariums can deliver measurable returns on investment through improved customer experiences, increased dwell time, and enhanced brand perception.

Let’s break it down.

The Science Behind the Benefit

Scientific research has shown that aquariums do more than just look good — they can have a profound effect on human psychology and behavior.

  • Cracknell et al. (2015) found that even a few minutes of exposure to an aquarium led to measurable reductions in anxiety, heart rate, and blood pressure.
  • Lam et al. (2001) demonstrated that visually stimulating environments (like aquariums) increase dwell time, a key metric in retail and service spaces that’s strongly linked to impulse buying and add-on purchases.
  • A meta-analysis revealed that aquariums can boost foot traffic by 11%, resulting in monthly sales increases exceeding $11,000 in mid-sized retail locations (Perdikaki et al., 2012; Kang, 2016).

The ROI Formula — Based on Real Business Data

Here’s a simplified model for a small to mid-sized business in an urban market like San Francisco:

  • Monthly revenue: $100,000
  • Foot traffic increase: 11%
  • Estimated sales lift: +$11,000/month
  • Average profit margin: 3.5%
  • Added monthly profit: $385

Even after accounting for routine maintenance (often included in service packages), the return remains consistently positive.

Annual Impact:

$4,620 in additional profit — all from a single design element.

Beyond Retail: Other Sectors Seeing Results

Healthcare Clinics

Aquariums help reduce patient anxiety, which can lead to fewer cancellations and less reliance on sedatives. Some clinics report 20–30% improvements in appointment retention and satisfaction scores.

Hospitality & Waiting Areas

First impressions count. Environments featuring aquariums are consistently rated as more professional and relaxing, influencing everything from online reviews to return visits and referrals.

Salons & Wellness Spaces

A calming, upscale ambiance paired with product displays can yield $500 to $2,000/month in extra revenue through increased sales of shampoos, candles, and other add-ons.

Intangible ROI That Impacts Your Bottom Line

Not all value shows up on a spreadsheet — but it still matters.

  • Enhanced brand perception
  • Higher-quality reviews and social media mentions
  • Reduced perceived wait times
  • Improved customer loyalty and retention

These all contribute to increased lifetime customer value, making your space not just more profitable, but more memorable.

Final Verdict: Aquariums Deliver

The data and the neuroscience agree: aquariums aren’t just decorative — they’re strategic business tools. They elevate customer experience, increase spending, and strengthen brand loyalty.

Whether you manage a retail store, dental clinic, hotel lobby, or wellness spa, an aquarium delivers tangible financial returns and a lasting impression.
