The Intex 58983 Metal Frame pool can be set up in just a few minutes, but the success of the installation hinges on what happens before the first tube is assembled. Poorly prepared ground, sinking legs, wrinkled liner: classic mistakes can lead to structural deformation within the first few weeks. This article measures the gap between a hasty installation and a methodical one, supported by technical data.
Dimensions and technical constraints of the Intex 58983 Metal Frame pool
Before choosing the location in your garden, you need to compare the dimensions of the pool with the actual constraints of the terrain. The 58983 model belongs to Intex’s rectangular Metal Frame Junior range, which comes in several sizes.

| Model (pool dimensions) | Height | Estimated ground footprint |
|---|---|---|
| 220 x 150 cm | 60 cm | Approximately 280 x 210 cm with legs |
| 260 x 160 cm | 65 cm | Approximately 320 x 220 cm with legs |
| 300 x 200 cm | 65 cm | Approximately 360 x 260 cm with legs |
| 300 x 200 cm | 75 cm | Approximately 360 x 260 cm with legs |
The actual footprint always exceeds the dimensions of the liner. The U-shaped legs extend on each side, and a circulation margin must be added. Allowing at least 50 cm of free space around the pool facilitates maintenance and the connection of the filter.
This guide for the Intex 58983 metal frame pool also details the specifics of the rectangular tubular frame and its points of caution depending on the configuration of your terrain.

Ground preparation: what makes the difference between a stable pool and a deformed frame
Competitors all mention the need for a flat terrain. The real question concerns the degree of tolerance and the measurable consequences of a level defect.
Flatness tolerance and pressure on the walls
A sloped ground, even slightly, causes an uneven distribution of the water mass. The additional pressure on the lower wall deforms the metal frame and asymmetrically stresses the liner. In a rectangular pool, this stress primarily affects the longer side, where the exposed liner surface is the widest.
Checking the level takes only a few minutes with a bubble level placed on a rigid board. The check should be done diagonally, not just along the length.
Plates under the U-shaped legs: a precaution that has become standard
Recent recommendations for rectangular Intex pools of similar sizes suggest placing a sturdy plate under each U-shaped leg, even on grass. This evolution aims to limit the gradual sinking into the ground, a problem frequently reported by after-sales services for several seasons.
Suitable supports include marine plywood, steel plates, or simply sufficiently wide concrete pavers. A leg sinking a few centimeters creates a cumulative imbalance: the frame works, the tube connections wear out, and the liner may tear at the seams.
- Marine plywood: moisture-resistant, stable surface, easy to reposition at the end of the season
- Concrete pavers: inexpensive, very stable, but should be checked for level as their thickness varies
- Steel or aluminum plates: distribute the load over a large surface, suitable for soft soils
Assembly of the rectangular tubular frame: mistakes that can be costly
The assembly of a rectangular Metal Frame follows a precise sequence. Unfolding the liner in the sun for about twenty minutes before assembly makes it more flexible and limits residual wrinkles. This detail, often overlooked, changes the quality of the final result.
Order of assembly and tension of the liner
The horizontal tubes connect to the T-pieces, then the U-shaped legs lock everything in place. The liner must be properly threaded onto the top tubes before raising the structure. Trying to reposition the liner after the frame is assembled creates wrinkles that are impossible to correct once water is added.
Filling the pool with a few centimeters of water before finalizing the positioning allows the weight of the water to stretch the bottom. Adjusting the wrinkles at this stage is still feasible. Beyond ten centimeters, the mass of water makes any correction very difficult.
Connecting the filtration system
The cartridge filter connects to the two valves of the pool (suction and return). The Intex manual recommends positioning the pump at a minimum distance from the pool to ensure sufficient flow and avoid pressure losses. On recent models, the pumps have splash protection, but they should never be placed below the water level or exposed to direct runoff.

Maintenance of the liner and water to extend the lifespan of the pool
A properly installed Metal Frame pool can last several seasons if the liner and water quality are regularly monitored.
- Check the water pH at least once a week with test strips, and adjust if necessary
- Clean the filtration cartridge every few days during the high season, replace it when the flow visibly decreases
- Cover the pool with a suitable tarp when not in use, to limit debris and slow algae growth
- Check the condition of the U-shaped legs and tubes after each episode of strong wind
A ground mat under the liner protects against punctures caused by stones, roots, or dry grass blades. This mat is cut to the dimensions of the pool and is placed before deploying the liner, directly on the prepared ground.
Storing at the end of the season deserves as much care as installation. Completely drying the liner before folding it prevents mold and unpleasant odors that weaken the material. Storing everything in a dry place, protected from frost, preserves the flexibility of the PVC for the following season.
The installation of an Intex 58983 Metal Frame pool in a garden relies on three technical points that condition everything else: the flatness of the ground checked diagonally, the placement of plates under each U-shaped leg, and the positioning of the liner before raising the frame. Neglecting any of these three points generates problems visible from the first week of filling.
