INTEX Ultra XTR 18 Ft Round Pool
The 18 ft x 52 in Ultra XTR round pool is designed for sizable outdoor spaces and family use. It includes a 6,981-gallon capacity and a heavy-duty 3-ply liner. The rust-resistant galvanized steel frame with UV-protected joints makes this model durable in sun and weather. Best for households that want a traditional round pool with solid water capacity and a long-lasting liner. A potential limitation is that the larger size requires ample yard space and proper level ground to ensure stability and safety.
INTEX Ultra XTR 24 Ft x 12 Ft Rectangular Pool (Sand Filter)
The 24 ft x 12 ft x 52 in rectangular Ultra XTR pool expands water space with a broad footprint suitable for open-water swimming and pool games. The frame is galvanized steel with inner and outer powder coating to resist rust, and it typically includes a 2100 GPH sand filter pump. Best for buyers who want a long, straight pool edge for lane swims or a more expansive interior. A caveat is that a rectangular design may require more precise leveling and anchoring in windy yards.
INTEX Ultra XTR 24 Ft x 12 Ft Rectangular (Saltwater System)
This 24 ft by 12 ft Ultra XTR rectangle pool uses a sand pump system, offering a different filtration approach compared with standard cartridge pumps. It maintains the same rust-resistant frame and 2-year warranty components. Best for buyers who want a robust filtration setup and quick maintenance cycles. Limitations may include higher upfront costs and the need for proper space planning for plumbing access around the pool.

Its ClickConnect joints simplify assembly and disassembly, making this model a strong pick for buyers who want a straightforward setup and reliable seasonal storage. Choose this if you value easy connections and durable steel framing; avoid if you need a saltwater system, as this model emphasizes standard filtration.
Bestway Steel Pro MAX 18′ Round Pool
The Bestway Steel Pro MAX features a robust steel frame and a 48-inch depth—slightly shallower than the 52-inch models, but often easier to handle and set up. It uses a quick-click connector system for fast assembly, making it ideal for first-time pool owners or those who want a simple teardown for winter storage. Best for buyers who prioritise ease of setup; avoid if you need maximum water capacity or a full 52-inch depth.

Buying Guide: 18 x 24 Above Ground Pool Purchases
What to consider when choosing an 18 x 24 above ground pool?
- Shape and space: Round pools fit smaller yards with more clearance around the sides; rectangular pools maximize swimming length and play space but require precise layout.
- Frame material and durability: Galvanized steel frames resist rust; aluminum frames are lighter but may not be as common in large round pools.
- Depth and capacity: Deeper pools offer more immersion and water volume; ensure the ground is level and able to support the weight when full.
- Filtration: Sand pumps, cartridge pumps, and saltwater systems each have maintenance considerations. Choose a system that aligns with your cleaning routine.
- Setup and storage: Look for quick-connect joints and tool-free assembly if you prefer an easy setup. Consider winter storage options for off-season use.
- Ground prep: A level surface with a stable base reduces liner wear and extends pool life. A ground cloth or tarp adds protection.
