From its bowl-shaped exhibition hall to the bronze figures - immortalised in mid-squat - outside, everything about a new theme park in South Korea points towards the smallest room in the house.
The Toilet Culture Park in the city of Suwon is reputed to be the first in the world devoted to what happens when we answer the call of nature.
Quirkier exhibits include WC signs from around the world and toilet-themed works of art.
The museum was previously the home of Sim Jae-duck, the former mayor of Suwon and the inspiration for the facility, where visitors are invited to use his original toilet, complete with a full-length glass door that clouds up when it's occupied.
South Koreans regard Sim, who died in 2009, and not Britain's Thomas Crapper, as the real Mr Toilet.
And for good reason: Sim was reportedly born in his grandmother's loo, and turned his obsession with toilets into a successful campaign in the 1980s to dramatically improve South Korea's public conveniences.
