That's according to a new report in the Washington Post, which says that Guggenheim curator Nancy Spector wrote in an email to the White House, "We are sorry not to be able to accommodate your original request, but remain hopeful that this special offer may be of interest".
The fully functional "America" toilet made from 18-karat gold was exhibited at the Guggenheim previous year.
Italian artist Maurizio Cattelan created the piece, entitled "America".
When President Donald Trump's White House emailed the Guggenheim Museum in New York City in September and asked to borrow Vincent Van Gogh's 1888 painting "Landscape with Snow", the curator from the famed institution had a counteroffer: A fully functional 18-karat gold toilet.
"It is, of course, extremely valuable and somewhat fragile, but we would provide all the instructions for its installation and care", she said in the email, The Post reported.
A spokeswoman for the museum confirmed to the Post that Spector sent the email to the White House, but did not comment further on the offer to the Trumps.

The White House did not respond to inquiries about the matter.
Cattelan began contemplating the idea for "America" before Trump became a serious candidate for president, according to the New York Times, but the participatory sculpture pretty much screams Trump, given his affinity for gold plate, including in bathroom fixtures.
"It's a very delicate subject", Cattelan told the Washington Post, when asked about his offer to the Trumps. And Spector has also spoken out against Trump, writing the day after the election on social media,"This must be the first day of our revolution to take back our beloved country from hatred, racism and intolerance".
"What's the point of our life?" he said. In February 2014, the Whitney Museum in NY loaned Obama two Edward Hoppers, which hung in the Oval Office.
"Everything seems absurd until we die and then it makes sense", he added.
A functioning gold plated toilet would have been the ideal artistic loan for the Trump White House.
But in a blog post a year ago about the exhibit, Spector made clear she viewed the piece as anti-Trump.
