Toddler Deep Squat Potty Design

I want a product called the Totsquat for my son, but it isn't sold in the UK. Therefore I'd like to commission a similar one myself! I'm seeking a design for a toddler potty that facilitates comfortable deep squatting at home. Key Requirements: - A single front handle for stability is essential. - Designed primarily for home use on the floor. - Must support comfortable deep squatting. Ideal Skills & Experience: - Background in product design, especially for children's items. - Experience with ergonomic design principles. - Knowledge of safe and durable materials for toddler products.
