This guide outlines typical scuba tank refill cost ranges in the United States. Buyers pay mainly for the refill itself, tank size, and service location. The main drivers are cylinder type (air vs. nitrox), fill density, and any digital or premium services.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Refill | $6 | $12-$18 | $25 | Standard air; nitrox may be higher |
| Tank Size (80–100 cu ft) | $0 | $0 | $0 | Included in refill price; no extra charge in many shops |
| Premium Fill (Nitrox) | $8 | $15-$25 | $30 | Depends on mix and certification requirements |
| Service Fee | $0 | $2-$5 | $10 | Some shops charge for handling or equipment checks |
| Hydro Test/Inspection | $0 | $0-$10 | $25 | Only if cylinder due for inspection |
Overview Of Costs
Typical cost range for a standard air fill on a common 80–100 cubic foot cylinder is about $6 to $18, with average around $12–$15 at most shops. When adding a nitrox fill, expect $15–$25 on average, with higher-end centers offering premium mixes with stricter certification. Assumptions: region, cylinder size, and mix type affect pricing.
Cost Breakdown
| Components | Low | Average | High | Assumptions |
|---|---|---|---|---|
| Materials | $6 | $12-$18 | $25 | Air or nitrox mix; cylinder integrity |
| Labor | $0 | $2-$5 | $10 | Staff time for handling and verification |
| Equipment | $0 | $0-$0 | $0 | Common refilling equipment covered by shop |
| Permits | $0 | $0-$0 | $0 | Not typically charged for standard refills |
| Delivery/Disposal | $0 | $0-$0 | $0 | In-store service default |
| Warranty / Safety Checks | $0 | $0-$2 | $5 | Basic visual inspection included |
| Taxes | $0 | $0-$2 | $3 | Depends on state tax rules |
What Drives Price
Fill type and tank size dominate cost. Air fills are cheaper and quicker; nitrox or trimix fills require additional certifications and handling. Cylinder condition and the number of fills per session can also shift pricing. Regional labor rates and shop demand create variability across markets, including peak season spikes.
Ways To Save
Shop around regional centers—some dive shops offer loyalty discounts or bulk-fill packages. Consider combining fills with gear rental or maintenance services to lock in a bundled rate. If not diving often, keep a current cylinder profile to minimize processing time per refill and reduce per-fill labor costs.
Regional Price Differences
Prices vary by market. In coastal tourist zones, expect higher base rates for nitrox and premium fills due to demand. Suburban shops may offer mid-range pricing, while rural centers often price more aggressively to attract local divers.
Real-World Pricing Examples
Assumptions: 80–100 cu ft cylinder, air fill or 32% nitrox, standard shop hours.
- Basic Scenario — Air fill only, 80 cu ft, casual diver: 1 fill, 6–8 minutes, total ~$8-$12; per-fill value around $0.10-$0.15 per cubic foot.
- Mid-Range Scenario — Air fill or standard nitrox, 100 cu ft, regular diver: 1 fill, ~10 minutes, total ~$14-$22; nitrox add-on impacts per-hour cost.
- Premium Scenario — Nitrox 32%, 100 cu ft, certification check, peak-season shop, multi-cylinder batch: total ~$28-$40; per-cubic-foot cost higher with specialized mix.
Additional & Hidden Costs
Hidden fees may include processing surcharges, certification verification, and equipment sanitization. Some shops charge for late returns or cylinder exchange, and hydro inspections add cost only if due. Understanding the regional price baseline helps avoid unexpected charges.
