The toilet features a wide ramp sloping from the roof level to the ground.
In the video, a man demonstrated how he could not slide down.
But MBPP Building Department chief architect Rizuwan Salleh said the slide was built for children.
“It might not be suitable for adults, especially those on the heftier side.
“It is just a fun activity for children to enjoy when going to the public toilet,” he said at a press conference in Komtar on Wednesday.
Rizuwan said the Miami Beach public toilet, which costs RM1mil, had been open to the public since January 2016.
“It has a baby room, a separate toilet for the disabled, separate surau for men and women, lockers, shower rooms and a bicycle dock with benches.
“The slide was just added for children to have some fun.
“We don’t know the man’s motives in the video, but calling Chief Minister Lim Guan Eng crazy is a serious matter,” Rizuwan said.
He pointed out that Lim did not have a hand in the design of the slide.
After getting stuck on the slide, the man in the video blurted the remark about Lim.
ZZM Architects founder Mei Chee Seong, who designed the building, said he tried the slide and could use it smoothly.
“If the slide was not functioning well, we would have received complaints by now.
“We are open to constructive criticisms.
“The entrance to the slide was narrowed to stop big-sized people from using it,” he said.
