CCTV cameras captured staff in her office removing equipment that had been installed when she took office eight years ago.
In a statement posted on social media, Lima said the bathroom renovations were paid for with her own money and were therefore not an asset owned by the council.
Lima said she followed the advice of the legal department, which said all personally installed resources should be removed.
She told Brazilian media G1 that the hydraulics in the building were “sensitive”.
She added that other fixtures she purchased for the office — such as the glass partition and industrial-style fixtures — will remain in place for her predecessor.
Lima held the position of adviser to the New Party until January 1.
In the 2024 elections, the 41-year-old woman ceded her position to Adrilia Jorge of the Labor Party of Brazil.
During his inauguration on Monday, Jorge quipped at G1 that his team will “use the common pot” until the situation is resolved.
“I visited the office and thought the architecture was brilliant. But it took everything,” he said.
“They even took out the toilet and sink. She didn’t say (that she would take them out). And that’s something she wouldn’t say, nor would I ask.”
The new president of the House of Representatives, Ricardo Teixeira, said that “appropriate measures” would be taken.
