You are looking for bestway hydrium 18 x 52 alternatives that match specific performance criteria. The original Bestway Hydrium 18' x 52" Steel Wall Pool Set offers a semi-permanent steel frame and a 7,192-gallon capacity. It includes a sand filter pump and uses a FastLatch assembly system for quick setup. This model suits buyers who need durable galvanized steel supports and a complete filtration kit in a mid-size footprint.
However, you might prefer different dimensions, a different brand, or a larger water volume. Some buyers need a rectangular shape for smaller yards, while others want maximum capacity for large families.

This list includes options with similar steel frames, sand filtration systems, and 52-inch heights. You will find larger rectangular pools and compact steel frame sets that provide comparable durability and filtration features.
Comparing Top Alternative Pool Sets
Bestway APX 365 31'4" x 16' Framed Pool
The Bestway APX 365 31'4" x 16' offers significantly more surface area than the 18-foot Hydrium. Its 31'4" length and 16' width provide a larger footprint for swimming. Both models share the 52-inch height and gray color scheme. This alternative uses a sand filter pump, matching the original filtration method. You gain substantial volume for larger families or gatherings. The trade-off is the increased space required in your yard. This option suits buyers who need maximum capacity and do not mind a larger installation footprint.
Evajoy 32ft x 16ft Rectangular Frame Pool
The Evajoy 32ft x 16ft Rectangular Frame Pool provides a massive 32-foot length compared to the Hydrium's 18 feet. It maintains the same 52-inch height and includes a sand filter pump. The blue color offers a distinct visual difference from the Hydrium's dark gray. This model is designed for large rectangular yards. You get a wider swimming area and similar durable construction. The main difference is the shape and size. This alternative is ideal for those who prioritize extensive swimming space over the compact, semi-permanent design of the original 18-foot model.
WaterThat 21ft Steel Frame Pool Kit
The WaterThat 21ft Steel Frame Pool Kit is slightly larger than the Hydrium, measuring 21 feet across. It shares the 52-inch height and includes a sand filter pump. The ashland color provides a neutral aesthetic. This option offers a complete DIY setup similar to the original. You gain a bit more swimming area while maintaining a manageable footprint. The trade-off is a different brand ecosystem and potentially different assembly hardware. This alternative fits buyers who want a steel frame with sand filtration but prefer a slightly larger diameter than the 18-foot Hydrium.
Intex Ultra XTR 32x16 ft
The Intex Ultra XTR 32x16 ft is a rectangular pool with a 32-foot length, far exceeding the Hydrium's 18-foot diameter. It shares the 52-inch height and uses a sand filter pump. The model number 26373EH identifies this specific large-scale unit. You gain a vast rectangular swimming area suitable for laps or large groups. The trade-off is the significant space requirement and different structural design. This alternative is best for buyers who need maximum water capacity and have ample yard space, rather than those seeking the compact, circular shape of the Hydrium.
Bestway APX 365 20' x 52" Pool Set
The Bestway APX 365 20' x 52" Pool Set is only 2 feet wider than the Hydrium. It shares the same 52-inch height and gray color. This model also includes a sand filter pump. You gain a modest increase in diameter and capacity. The trade-off is minimal, as it is part of the same brand family. This alternative is ideal for buyers who want the familiar Bestway build quality but need slightly more swimming space. It fits those who find the 18-foot model too small but do not want a massive rectangular pool.
Bestway Power Steel 24' x 12' x 52" Frame Pool
The Bestway Power Steel 24' x 12' x 52" Frame Pool offers a rectangular shape with a 24-foot length. It shares the 52-inch height and gray color. This model includes a sand filter pump and provides 7,937 gallons of capacity. You gain a longer swimming lane and a different footprint shape. The trade-off is the narrower 12-foot width compared to the Hydrium's 18-foot diameter. This alternative suits buyers who prioritize volume and linear swimming space over a circular, wide-area design. It is a robust option for larger yards.
