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.
