The Air Head Standard used to be referred to as the ‘household’ and the Air Head Compact was the ‘marine’. The names were changed to reflect a shift in the customer base.
The only difference is the overall depth of the toilet seat and lid – on the Air Head Standard, you’ll find a full-sized toilet seat, and in order to accommodate this, the hinges protrude beyond the rear of the toilet. With the Air Head Compact, the seat is shallower (front to back) and the hinges are inset into the body. This means the Air Head Compact model can be fitted about 3cm closer to the wall – ideal if your space is really tight.
