While digging details on A Loo with the View (the Book), I stumbled upon Loo with a View (the company).
Couple Ric and Lyn Kinghorn founded the company in 1996 and maybe because of their location on the Sunshine Coast of Australia (in Queensland) created a line of Toilet Seats that draw all their inspiration from the sea.
I would rather go for the Shell Clear Set (picture above) than the Barbed Wire Clear Seat (pictured below).
This one reminds me more of military training than anything else.
Any of their designs will definitely get the conversation going amongst your guests.
