I am interested in exploring options for a large-capacity spa unit with a capacity of around 1000 liters. Could you provide detailed specifications regarding the features, design, and available configurations? Additionally, I'd appreciate information on the materials used, energy efficiency ratings, and any customization options you may offer to better tailor the product to my needs. Furthermore, please include pricing details, lead times for production and delivery, as well as any warranty or after-sales support available. Understanding the potential for bulk purchasing or any discounts for larger orders would also be beneficial. Looking forward to your prompt response so we can discuss this further!
