What Is an Infinity Pool?
An infinity pool (also known as a vanishing edge pool) is a luxury design where one or more edges of the pool appear invisible, with water flowing over the edge into a hidden catch basin and then being pumped back. This creates a stunning visual illusion that makes the pool appear to extend into infinity.
Infinity pool prices start from 80,000 SAR and reach 250,000 SAR or more depending on the size, design, and number of vanishing edges.

Infinity Pool Requirements
An infinity pool requires a suitable site with an elevation difference to achieve the desired visual effect. Key requirements include:
Infinity Pool Prices
| Design | Approx. Price (SAR) | Timeline |
|---|---|---|
| Small Infinity (single edge) | 80,000 - 120,000 | 60-75 days |
| Medium Infinity (single edge) | 120,000 - 180,000 | 70-85 days |
| Large Infinity or double edge | 180,000 - 250,000+ | 80-100 days |
How an infinity pool actually works
The idea is simple; the execution is not. One wall — the weir wall — is built a few millimetres below the water line, so water sheets over it in a thin film and falls into a hidden catch basin below. A second pump returns it to the pool, continuously.
That gives three real differences from any ordinary pool:
This is why an infinity pool costs more and takes longer than a standard build. The difference is not decorative: it is an additional structural wall, a basin, a pump, and precise survey work.
What changes in the Saudi climate
Most published guidance on infinity pools assumes a temperate climate. Here the arithmetic shifts, and the cause is the same thin film that creates the view:
| Factor | Effect on an infinity pool |
|---|---|
| Summer heat and dry air | Water moving as a thin film meets far more air than a still surface, so evaporation rises. Daily loss is higher than a standard pool of the same size. |
| Wind | Strong wind pushes part of the sheet past the catch basin. Orient the edge away from the prevailing wind, or reduce flow on windy days. |
| Hard water | Constantly topping up the loss keeps introducing fresh minerals. They concentrate and deposit along the weir edge as a visible white line — the most common complaint on infinity pools here. |
| Warmer water | The stabiliser protecting chlorine from sunlight breaks down faster as water temperature rises, and moving water heats faster than still water. Chemistry needs checking more often in summer. |
| Catch basin capacity | Size it with margin for evaporation and loss, not to the minimum. An undersized basin means constant refilling and a pump at risk of running dry. |
None of this is a reason to avoid the design — infinity pools work very well in the Kingdom. These are the details that decide whether it still looks the way it did in its first week three years later.
