Indoor Pool Design Considerations

Pool tied to building. Often architects specifying indoor pools will place the pool hard up against one wall with the wall of the building running into the pool. While aesthetically pleasing this opens up a can of worms with regards to the integrity of the pool structure. Settling of the foundations or movement in the building can result in water loss from the pool shell due to the stress involved. It is also impossible to access any services located behind this wall, for example pool lights, return inlets etc. The recommended method in this instance is to locate the pool 350mm from the building that is enough for a coping

Most domestic pools are of the ‘freeboard’ design. That is to say that the water level is approximately 150mm below the level of the pool deck or 50-100mm in the case of a compass design line. Surface water draw-off is via a number of surface water skimmers (quantity dependent on overall volume of pool) set into the pool wall at finished water level.
