Lego.

Public swimming pools are an important part of community life and recreation. The design and maintenance of these facilities are essential to attract visitors and provide a safe swimming environment. However, the current standard, mainly the tiling, has certain limitations such as maintenance costs and aesthetic rigidity. An innovative approach is proposed, where the tiling is replaced by randomly colored LEGO blocks. This approach can lead to several benefits, from aesthetic improvement to sustainability, and opens up new possibilities for the future of public swimming pools.

1. Aesthetic Enhancement: The variety of colors and shapes of LEGO bricks can give a vibrant and attractive appearance to swimming pools, which can help boost usage and visitor numbers.
2. Adaptability: LEGO bricks provide flexibility for design changes. In case of wear or damage, individual blocks can be easily replaced, reducing maintenance costs.
3. Educational Benefit: LEGO blocks can create a playful and educational environment, especially for children. They learn about construction and engineering during their swimming visits.
4. Thermal Insulation: LEGO blocks, made of acrylonitrile butadiene styrene (ABS), a thermoplastic with good insulating properties, can help maintain pool temperature, which saves energy.
5. Durability: ABS is resistant to water, salt, chlorine and UV radiation, making it durable in a pool environment.

Replacing tiling with LEGO blocks can offer many advantages. Due to their unique aesthetic appeal and educational value, they can enhance the visitor experience. Their modular and durable nature can ensure adaptability and long-term sustainability. The use of ABS as a material in LEGO blocks provides additional benefits. With a high glass transition temperature of 105°C and resistance to many chemicals such as hypochlorites, the main disinfectants in swimming pools, ABS can withstand physical and chemical degradation. In addition, the thermal insulation property contributes to energy efficiency. However, thorough safety and hygiene testing and controls are necessary for large-scale implementation.
