Semi-Inground Pools: The Ultimate DIY Guide for Your Backyard Oasis 2026

Semi-inground pools have always been a quality "plus" for relaxation in your outdoor spaces. The dream of owning a pool is not an unattainable fantasy, but the costs involved deserve careful consideration. Beyond the installation expenses, semi-inground pools require ongoing management costs: water consumption, electricity, products to combat algae and bacteria, and heating. These costs can run between €6 and €18 per day depending on the size. However, if you only use your semi-inground pool during the summer season, you can deduct heating from your operating expenses. For the best quotes, avoid late spring and aim for September-October, when the "low season" makes contractors and manufacturers more willing to negotiate prices to secure the job.

To limit water consumption, you need a recirculation system that not only recovers water but also provides filtration and purification—essential for hygiene and aesthetics, to prevent grayish buildup on the edges at the waterline. Explore our home improvement collection for tools and supplies to keep your pool area in top shape.

Prefabricated Semi-Inground Pools

Prefabricated semi-inground pools are the most popular solution for getting a real pool. Once you've excavated the site and poured a concrete base, you have several options. The simplest and most economical is to lower a preformed shell, usually made of fiberglass or acrylic, level it, and backfill evenly around it. The alternative is steel modules that you assemble and line with a long-lasting PVC liner—an interesting compromise between a prefab shell and a reinforced concrete pool. In both cases, costs are significantly lower than building a custom pool, and you can be swimming in just a few days.
