Plastic vs Aluminum Custom Water Bottles: Which Is Right?
Last Updated: March 18, 2026
Plastic vs Aluminum Custom Water Bottles: The Key Difference
Plastic (PET) custom water bottles cost $0.26-$0.50 per bottle and are the standard for high-volume orders. Aluminum custom water bottles cost $0.40-$0.75 per bottle and deliver a premium look with stronger sustainability credentials. Both are available from the same suppliers with the same custom labeling options.
The right choice depends on your budget, your brand positioning, and how the bottles will be used. This guide compares every factor so you can decide.

When Plastic Is the Right Choice
Plastic is the right choice for most custom water orders. It is cheaper, lighter, available in more sizes, and is what people expect when they pick up a bottle of water.
- High-volume events: Trade shows, large conferences, festivals. When you need 1,000+ bottles, the $0.15-$0.20 per bottle savings adds up fast.
- Daily office supply: Break rooms, reception areas, conference rooms. Functional hydration where premium feel is not the priority.
- Weddings on a budget: At $0.26/bottle, plastic custom water is one of the cheapest personalization options at any wedding.
- Small bottle needs: 8oz bottles for welcome bags, waiting rooms, and quick-serve situations. Aluminum is not available in 8oz.
- Price-sensitive buyers: When per-bottle cost is the primary decision factor.
When Aluminum Is the Right Choice
Aluminum is the right choice when the bottle itself is part of the brand message. The metal body, the resealable cap, and the full-wrap label create a product that feels intentional and premium.
- Executive and client-facing events: Board meetings, investor presentations, client dinners. The bottle on the table signals attention to detail.
- Eco-conscious brands: Companies with sustainability messaging. Aluminum’s infinite recyclability reinforces the brand story.
- Luxury hospitality: Premium hotel suites, high-end spas, VIP areas. Aluminum matches the aesthetic.
- Outdoor events with resealable need: Golf tournaments, outdoor galas, sporting events. The metal screw cap keeps water fresh for hours.
- Brand differentiation: When every other company at the event has plastic water, aluminum stands out.
Cost Comparison at Scale
| Order Size | Plastic at $0.26 | Aluminum at $0.45 | Difference |
|---|---|---|---|
| 24 cases (576 bottles) | $150 | $259 | $109 |
| 50 cases (1,200 bottles) | $312 | $540 | $228 |
| 100 cases (2,400 bottles) | $624 | $1,080 | $456 |
| 500 cases (12,000 bottles) | $3,120 | $5,400 | $2,280 |
For a 100-case order, the aluminum premium is $456. For a company spending $50,000 on an event, that is less than 1% of the budget for a noticeable upgrade in brand presentation.
Can You Use Both?
Yes, and many companies do. A common approach:
- Aluminum for executive settings, client meetings, and VIP areas
- Plastic for general distribution, trade shows, and high-volume events

“About 30% of our corporate clients order both. Aluminum for the boardroom, plastic for the break room. Same brand, different impression.” — Danielle, CEO of CustomWater.com
Frequently Asked Questions
Is aluminum really better for the environment than plastic?
Aluminum is infinitely recyclable and has a higher recycling rate (50% vs 29% for PET plastic in the US). However, aluminum production has a higher initial carbon footprint. The net environmental benefit depends on recycling behavior. For brand perception, aluminum is the stronger sustainability signal.
Can I get aluminum bottles in sizes other than 16oz?
Currently, CustomWater.com offers aluminum in 16oz only. Plastic is available in 8oz, 12oz, and 16.9oz. If you need a smaller bottle, plastic is the only option.
Do aluminum bottles cost more to ship?
Yes, slightly. Aluminum bottles are heavier than plastic, which increases freight cost per case. CustomWater.com’s 10-facility network helps offset this by shipping from the closest plant.
Which looks better on a table?
Aluminum. The metal body, full-wrap label, and resealable cap create a more polished presentation than plastic. For formal settings (boardrooms, galas, hotel lobbies), aluminum is the clear winner.
