Bestway Hydrium™ 7.32m × 3.66m × 1.32m Oval Steel Wall Above Ground Pool Set — Model 561CW is Bestway’s flagship large-format oval above ground pool — a 24′ × 12′ × 52″ premium Hydrium Steel Wall pool set that delivers genuine semi-permanent above ground pool quality and performance at a scale and structural specification that places it in a category of its own among above ground swimming pool options. At 27,090 litres at 90% fill, the 561CW provides one of the largest above ground swimming experiences available — a full-sized oval pool with reinforced 16 cm wide steel sidewalls, UV-protective coating, high-strength PVC bowl construction, and a complete sand filter system that requires no seasonal dismantling. The oval shape at 7.32 metres long and 3.66 metres wide delivers maximum swimming length for genuine lap swimming, structured water sport, and simultaneous multi-swimmer use across the full 1.15-metre usable water depth.

The Hydrium Steel Wall construction is a fundamentally different pool platform from framed-liner above ground pools — the pool walls are formed from wide-format reinforced steel panels (16 cm wide along the edge) that create rigid structural sidewalls capable of maintaining pool shape and integrity without seasonal disassembly. A special UV coating on the steel wall panels protects against solar UV exposure, preventing surface degradation and colour fade that compromises both structural integrity and visual quality over multi-season outdoor use. The pool bowl is fabricated from high-strength PVC seated inside the steel wall frame — a construction method that distributes water pressure load across the steel wall structure rather than concentrating it entirely on the liner material as standard framed PVC pools do. The included sand filter pump circulates 5,678 litres per hour through a 25 kg sand tank with 38 mm corrugated hose connections — providing commercial-quality sand filtration sized appropriately for a 27,090-litre pool that requires serious ongoing filtration capacity to maintain water clarity. The ChemConnect™ chemical dispenser integrates into the pool’s water circulation to maintain stable, evenly distributed chlorine levels automatically. The included surface skimmer continuously removes floating debris at the waterline before it sinks to the pool floor, maintaining a clean water surface passively between cleaning sessions. The full set arrives palletised — boxed, protected, and delivered on a pallet — reflecting the scale and value of this premium pool system.

Key Features
- Hydrium™ Reinforced Steel Sidewall Construction — 16 cm Wide UV-Coated Steel Panels: The 561CW’s defining structural characteristic is its Hydrium Steel Wall construction — a pool wall system built from wide-format (16 cm) reinforced steel panels rather than the flexible PVC liner walls used in standard above ground pools. These rigid steel sidewalls create a structurally self-supporting pool perimeter that maintains its shape independently of the water pressure inside, unlike framed-liner pools where the liner is the primary structural containment element. The special UV coating on all steel wall panels protects against solar UV radiation — preventing the surface oxidation, colour fade, and material embrittlement that untreated steel experiences with prolonged outdoor sun exposure. The combination of reinforced steel construction and UV protection means the 561CW is engineered for years of outdoor installation without the structural degradation that limits the usable lifespan of standard above ground pools
- High-Strength PVC Bowl — Seated Within Steel Wall Structure: The pool’s water containment is provided by a high-strength PVC bowl that is seated inside the steel wall frame — a construction approach where the steel walls bear the structural load of containing the 27,090-litre water volume, while the PVC bowl provides the watertight inner surface. This load distribution across the steel structure, rather than concentrating water pressure entirely on the liner, is a fundamentally more durable containment engineering approach than standard framed PVC pools where the liner material alone resists the full outward water pressure
- No Seasonal Dismantling Required — True Semi-Permanent Installation: The 561CW’s super-sturdy Hydrium Steel Wall construction is robust enough to remain installed throughout the year without seasonal disassembly — unlike frame-and-liner above ground pools that are typically disassembled in autumn and reassembled in spring. The pool can be left standing across seasons with the steel walls maintaining their structural integrity through winter conditions. If relocation or storage is needed, the pool can be disassembled and reassembled without specialist tools, but for most owners the 561CW will remain in position as a permanent backyard feature
- Sand Filter Pump — 5,678 L/h with 25 kg Sand Tank and 38 mm Hoses: The 561CW’s filtration is provided by a dedicated sand filter pump — a fundamentally superior filtration technology compared to cartridge filter systems for a pool of this volume. The 25 kg sand tank traps fine particulate matter down to approximately 20–40 microns, self-regenerates through a backwash cycle that cleans the sand media in-place without cartridge replacement, and maintains filtration effectiveness across a full swimming season with minimal maintenance. At 5,678 L/h, the pump provides the flow rate required to cycle and filter a 27,090-litre pool effectively. The 38 mm corrugated hoses provide large-bore flow connections that minimise pressure loss between the pool and pump
- ChemConnect™ Dispenser — Automatic Stable Chlorine Distribution: The ChemConnect dispenser connects to the pool’s water circulation system and continuously releases a stable, measured level of chlorine that is evenly distributed throughout the entire 27,090-litre pool volume as water circulates — not concentrated near a manual tablet drop point. At this pool volume, manual chlorine dosing produces significant uneven chemical distribution between dosing events. The ChemConnect dispenser maintains consistent sanitisation across the entire pool simultaneously, preventing localised under-treatment in areas far from the chemical source
- Integrated Surface Skimmer — Continuous Waterline Debris Removal: The included skimmer is connected to the pool’s water circulation system and continuously draws surface water through a debris-collection basket at the waterline, removing floating leaves, insects, sunscreen residue, and other surface contaminants before they sink to the pool floor. A pool of 7.32m × 3.66m has a very large water surface area that accumulates debris rapidly — the skimmer provides continuous passive surface cleaning that significantly reduces the frequency of manual net cleaning required to maintain a visually clean pool
- Oval Shape — Maximum Swimming Length, Oval Space Efficiency: At 7.32 metres long, the 561CW provides genuine lap swimming distance — the oval shape preserves the full 7.32-metre swim length across the pool’s entire width, unlike rectangular pools where parallel walls create maximum length but the oval’s gentle curves at each end allow a wider mid-pool swimming zone than a purely rectangular design. The oval footprint also provides better garden integration than a rectangular pool of equivalent length — the curved ends reduce the visual and physical impact in garden spaces where a fully rectangular structure would feel more imposing
- 1.15m Usable Water Depth — Full Adult Submersion: The 561CW’s 1.15-metre water depth provides genuine full adult submersion capability — swimmers can stand shoulder-deep, perform underwater swimming strokes, and experience a pool depth that makes the 561CW feel like a full-scale swimming facility rather than a wading pool. This depth is particularly significant for the 561CW’s size — at 7.32 × 3.66 metres, the combination of maximum swim length and true adult depth creates a complete swimming experience that standard 42″ or 48″ above ground pools cannot match
- Ground Cloth — Pool Base Protection: The included ground cloth is laid beneath the pool bowl before installation to protect the PVC bowl’s underside from puncture, abrasion, and ground moisture penetration. At 7.32 × 3.66 metres, the pool base surface area is extensive — the ground cloth protects this entire surface from below, extending the bowl’s service life and preventing ground-level damage that would be difficult and disruptive to repair with the pool fully installed
- Safety Ladder — 1.32m Secure Pool Access: The included 132 cm safety ladder provides stable, controlled entry and exit access at the 1.32-metre wall height — a height that requires a proper ladder for safe access, particularly for children. The ladder’s safety design supports family use across all ages for a pool that, at this size and depth, demands reliable and controlled pool access rather than improvised entry methods
- Palletised Delivery — Protected, Professional Handling for a Major Purchase: The 561CW arrives on a pallet — a delivery format that reflects the scale and value of this premium pool system. Palletised delivery protects all components from freight damage during transit and ensures every item in the complete set — pool bowl, steel wall panels, sand filter pump, corrugated hoses, skimmer, ChemConnect dispenser, pool cover, ground cloth, safety ladder, drain valve adapter, and repair kit — arrives intact and undamaged, ready for installation

User Benefits
- A Pool You Install Once — and Leave Standing: The Hydrium Steel Wall construction eliminates the annual disassembly-and-reassembly cycle that above ground pool ownership typically involves — the 561CW is installed once, stays in position, and is ready to use every swimming season without the significant time investment of full seasonal setup and takedown. For families who want a permanent backyard pool without the cost and construction complexity of an in-ground installation, the 561CW represents a uniquely practical solution
- 27,090 Litres of Full-Scale Swimming Space: At 7.32 metres long, 3.66 metres wide, and 1.15 metres of usable depth, the 561CW provides a swimming environment that accommodates lap swimming, water sports, children’s pool games, and multiple simultaneous adult swimmers in a single pool — a volume and footprint that no standard above ground pool can approach. The full adult depth means everyone in the family gets genuine immersive swimming, not just partial-body wading at the edge
- Sand Filtration — Better Water, Less Maintenance Cost: Sand filter technology provides substantially better long-term filtration economics than cartridge systems for a pool this size — no ongoing cartridge replacement purchases, no filter maintenance beyond periodic backwashing that takes minutes and requires no consumable parts. Sand media lasts for several years before needing replacement, making the 561CW’s filtration running costs significantly lower than an equivalent cartridge-pump pool at this volume
- The Surface Stays Clean Automatically — Even Between Sessions: The integrated skimmer collects floating debris continuously as the pump runs — leaves, insects, pollen, and surface contaminants are removed passively before they decompose and affect water quality or sink to create manual cleaning requirements. For a pool of 7.32 × 3.66 metres with a very large surface exposure, the skimmer’s continuous passive cleaning significantly reduces the manual net-cleaning frequency needed to maintain a visually pristine pool surface
- Chemical Balance Managed Automatically: The ChemConnect dispenser maintains the correct chlorine level evenly across 27,090 litres continuously — eliminating the need for daily manual chemical dosing and the uneven chemical distribution that manual dosing produces in a pool of this volume. Consistent, even chlorine levels across the entire pool mean fewer algae problems, less shock treatment, and reduced overall chemical spending across the season
- The Complete System — Delivered to Your Door: Every component required to install, fill, filter, clean, and maintain the 561CW arrives in a single palletised delivery — pool bowl, steel walls, sand filter pump, hoses, skimmer, ChemConnect dispenser, pool cover, ground cloth, safety ladder, drain valve adapter, and repair kit. There is no secondary equipment list to source separately, no missing components to order before installation can begin, and no compatibility research needed. The 561CW is a complete, operational above ground pool system in one purchase
- Steel Walls That Last the Outdoor Season — With UV Protection: The UV coating on the Hydrium steel wall panels addresses the primary weathering failure mode of outdoor steel — UV-driven surface oxidation that leads to rust initiation and eventual structural compromise. Protected steel wall panels maintain their coating integrity, surface finish, and structural strength across full outdoor seasons including the intense sun exposure of summer months, significantly extending the pool’s effective structural lifespan compared to uncoated steel
