美国采购需求：家禽养殖场、钢结构仓库、集装箱房屋、洗手站、移动厕所

I'm looking to source single toilet and sink units for a project. Ideally, these should be high-quality, durable, and suitable for a variety of environments, such as residential and commercial spaces. Could you provide detailed specifications, including materials, dimensions, and any available design options? Additionally, I'd like to know your pricing structure and any minimum order quantities you may have. Please send me your catalog or any available information at your earliest convenience. Thank you!
