What Is the Bestway Steel Pro MAX?
The Bestway Steel Pro MAX is Bestway’s large-family pool line, available in 14ft through 22ft round. It sits above the Power Steel in Bestway’s lineup in terms of size range — the Power Steel tops at 18ft, while the Steel Pro MAX extends to 22ft — and is specifically positioned as a family pool with enough surface area for multiple children to swim without congestion.
The liner construction is the same TriTech three-layer system as the Power Steel, earning a 3/5 Liner-Durability Score. The frame uses the same bolt-connector system. The key differentiator vs. the Power Steel is the extended size range and the 52-inch depth option available at the larger sizes — making it a more credible adult swimming pool than the Power Steel’s 48-inch maximum.

Liner Durability: TriTech Performs Well for Active Families
The Steel Pro MAX’s TriTech liner earns a 3/5 Liner-Durability Score — the same as the Bestway Power Steel. What changes at the Steel Pro MAX’s larger sizes is that the liner faces higher water pressure and more total surface area stress. The TriTech construction handles this adequately at 14–18ft. At 20–22ft, buyers who want the strongest liner at this size tier should consider the Intex Ultra XTR instead, where the three-ply construction better handles the increased pressure at very large volumes.
For the target use case — families with multiple children swimming actively — the TriTech liner’s track record is solid. Rough-use durability ratings (based on verified buyer reports from high-use family pools) show the Steel Pro MAX liner handling active family use through two full seasons reliably, with season three showing the first signs of seam stress at the ladder cutout and drain fitting in a minority of pools.
| Rough-use durability: what the 3/5 score means for families Children jumping in and out: TriTech handles this. The three-layer construction absorbs impact stress at the waterline better than single-layer liners. Multiple swimmers daily: adequate. The liner performs well under high-frequency use at correct water chemistry. Teenagers pushing off walls: this is where the 3/5 score shows its ceiling. Repeated lateral force against the liner at frame joints is the most common cause of early failure. The Intex Ultra XTR’s 4/5 liner handles this better. Pets with claws near the pool: all above ground pool liners, including TriTech, are vulnerable to pet claw contact. Keep pets away from the pool area regardless of liner quality. |
Setup Experience: Same System as Power Steel, More Components
The Steel Pro MAX earns a 3/5 Setup-Difficulty Score. The bolt-connector frame system is identical to the Bestway Power Steel. What changes at 18–22ft is the sheer number of components — more uprights, more top rail sections, more T-joints — which extends the setup time without increasing the per-step difficulty. Plan 4–5 hours with two adults for the 18ft, and a full day for the 20–22ft sizes.
The liner installation at 20–22ft is the most physically demanding step: a 22ft liner is heavy and awkward to seat evenly inside the frame. Three adults make this step significantly easier at 20ft and above. Two adults can manage it but expect the liner seating to take 30–45 minutes of effort at these sizes.
| Steel Pro MAX setup tips for large sizes At 20ft and above: recruit three adults if possible. Liner installation with two is manageable but genuinely hard at this size. Frame assembly tip: sort all bolts and connectors by type before starting. The Steel Pro MAX has more component varieties than the Power Steel at large sizes — sorting first prevents mid-assembly confusion. The 22ft liner at 52″ depth holds over 14,000 gallons. Once you start filling, you’re committed — make sure the ground prep is correct before the first drop of water goes in. Pump connection: the Steel Pro MAX at 20–22ft uses a 1.5-inch hose fitting. If upgrading the pump (strongly recommended at these sizes), verify 1.5-inch compatibility before ordering. |

At 15ft: the Power Steel and Steel Pro MAX are similar pools at similar prices — buy whichever is cheaper. At 18ft: the Steel Pro MAX vs. Power Steel difference is minimal (same liner, similar price). The real upgrade question at 18ft is Steel Pro MAX vs. Ultra XTR — the Ultra XTR’s 4/5 liner is worth $120–150 more for buyers planning 3+ seasons. At 20–22ft: the Steel Pro MAX is the only Bestway option, and holds up well vs. the Ultra XTR at equivalent sizes on everything except liner grade.

Who the Bestway Steel Pro MAX Is Right For
Large families with multiple children: The extended size range (up to 22ft) gives genuine swimming room for four to six swimmers simultaneously.
Buyers who want Bestway and need more than 18ft: The Power Steel tops at 18ft. The Steel Pro MAX is the only way to get a Bestway pool at 20–22ft.
Buyers in the 15–18ft range where Power Steel is out of stock: Same liner quality, same frame system — buy whichever is available and cheaper.
Who Should Skip the Bestway Steel Pro MAX
Buyers prioritising liner durability at 18ft+: The Intex Ultra XTR’s 4/5 liner is meaningfully better than TriTech’s 3/5 at this size. Worth the extra $120–150 for 3+ season ownership.
Buyers with yards under 22x22ft: The 18ft Steel Pro MAX needs 22x22ft of flat space. The Power Steel or Prism Frame in smaller sizes are better fits for tighter yards.
Buyers who want an oval option: The Steel Pro MAX is round only. The Bestway Power Steel offers oval at 12x20ft and 12x24ft.
Frequently Asked Questions
What is the difference between Bestway Power Steel and Steel Pro MAX?
The Steel Pro MAX extends Bestway’s range beyond the Power Steel’s 18ft maximum, offering 20ft and 22ft round sizes with 52-inch depth options. Liner construction (TriTech, 3/5 score) and frame system (bolt connectors) are the same between the two lines. At 14–18ft, the two pools are essentially equivalent — buy whichever is cheaper or better stocked.
Is the Bestway Steel Pro MAX good for families?
Yes — it’s Bestway’s strongest family pool option. The TriTech liner handles active child use reliably for two to three seasons, and the size range (up to 22ft) provides genuine swimming room for large families. The main limitation vs. the Intex Ultra XTR is liner grade at 18ft and above.
How long does the Bestway Steel Pro MAX last?
Frame: 5–8 years with annual rust inspection and coating touch-up. Liner: 2–3 seasons with regular family use and correct water chemistry. Replacement liners are available from Bestway and third-party suppliers and are compatible across the Steel Pro MAX and Power Steel lines at equivalent sizes.
What pump do I need for a Bestway Steel Pro MAX 18ft?
The included 1,500 GPH pump is marginal for an 18ft pool at 48–52 inches depth (~7,600–8,300 gallons). Upgrading to a 2,000–2,500 GPH pump improves water clarity and filtration reliability. See our pump sizing guide for specific models compatible with 1.5-inch Bestway fittings.
Is the Bestway Steel Pro MAX the same as the Coleman Power Steel?
No — the Coleman Power Steel and Bestway Power Steel are the same pool (Coleman licenses the brand to Bestway). The Steel Pro MAX is a separate, larger product line within Bestway’s own lineup, not sold under the Coleman brand. Coleman-branded pools in the US typically correspond to the Power Steel and budget lines, not the Steel Pro MAX.
