For homeowners considering an inground pool but constrained by yard space or landscaping plans, the semi inground pool presents an attractive compromise. These structures blend above and below ground aesthetics, offering the presence of a traditional pool with a modified installation process. Understanding the precise semi inground pool dimensions is vital for ensuring the design complements your outdoor area and adheres to local building regulations.
Defining the Semi Inground Pool
The term "semi inground" describes a pool that is partially buried. Unlike a standard inground pool, which is excavated entirely below the surrounding grade, a semi inground model typically sits with the walls rising a significant distance above the ground. This design allows for greater flexibility in placement, making it a popular choice for uneven terrain or areas where full excavation is impractical. The semi inground pool dimensions are largely dictated by the structure of the walls themselves, which are often pre-formed in standard sizes.
Standard Wall Heights and Overall Depth
The most critical dimension to consider is the height of the pool wall. While custom options exist, the industry standard for semi inground pools is a wall height of 48 inches. This means the top of the wall sits 4 feet above the ground at the point of installation. Because the floor of the pool is set into the earth, the total depth of the water far exceeds this wall height. A typical semi inground pool with a 48-inch wall will have an actual swimming depth ranging from 54 to 60 inches, depending on the specific slope of the pool bottom design.
Typical Dimension Breakdown
To visualize the scale of a standard installation, consider the following common specifications for a rectangular model:
| Wall Height | Typical Overall Length | Typical Overall Width | Approximate Water Depth |
|---|---|---|---|
| 48 inches | 15 to 16 feet | 10 to 12 feet | 4.5 to 5 feet |
Round and Oval Variations
Semi inground pools are not limited to rectangular shapes. Circular and oval designs are also common and adhere to similar height principles. A standard round semi inground pool usually features a diameter of 15 or 16 feet, with the same 48-inch wall height. This results in a water depth suitable for adults, generally around 4.5 to 5 feet. Oval models follow the same logic, offering a larger surface area than a round pool of equivalent wall height, with common dimensions of approximately 15 feet by 20 feet.
Factors Influencing Final Dimensions
It is essential to remember that the semi inground pool dimensions can vary based on site-specific conditions. If the pool is installed on a slope, one side of the wall may need to be buried deeper to achieve level coping, effectively changing the shallow and deep ends. Additionally, local building codes may dictate maximum wall heights or require specific safety barriers, which can impact the usable dimensions of the pool. Always consult with a local contractor to assess how the terrain and regulations will affect the final build.
Space Planning and Landscaping
Because the walls are exposed, the semi inground pool acts as a hardscape element in the yard. This requires careful planning regarding the surrounding landscape. You must account for the 4-foot-high barrier when planning fencing for safety or screening with plants. The footprint of the pool—calculated using the length and width dimensions—will determine how much yard space is required. Ensure you leave adequate room for decking, pathways, and maintenance equipment around the perimeter of the walls.
Customization vs. Standardization
While standard dimensions ensure cost-efficiency and availability of parts, some manufacturers offer customization for the semi inground pool dimensions. You might find wall heights of 36 inches for a shallower play pool or 54 inches for a deeper diving experience. However, deviating from standard sizes often increases the lead time and cost of the kit. For most DIY enthusiasts and contractors, sticking with the 48-inch wall height provides the best balance of depth, usability, and straightforward installation.
