It was released on 21 June 2019 and was co-produced by Hot Chip, Philippe Zdar, and Rodaidh McDonald, marking the first time the group worked with outside producers.

Preliminary songwriting for A Bath Full of Ecstasy was undertaken by Hot Chip members Alexis Taylor and Joe Goddard, and first traces back to work they did for pop singer Katy Perry.

[4] When the members of Hot Chip re-convened to record A Bath Full of Ecstasy, they decided to work with outside producers for the first time and to allow them to have a say in the songwriting.

[4] After meeting with several producers, the band chose to work with Philippe Zdar of French musical duo Cassius, as well as Rodaidh McDonald.

He recommended to the group where to add bridges, choruses, and hooks, how many bars they should last, and he considered how the songs should be edited differently for radio or streaming services.

[4] Zdar, on the other hand, was more interested in fostering a collaborative atmosphere in the studio amongst the band members and capturing the moments of "fun improvisation".

[3] Taylor said Zdar had a knack for spotting the vocal melodies and hooks in songs, and his mixes emphasised them while also giving "more space in the music".

[7] Goddard called him "bold and passionate" and praised his skills at "working with bass, making records feel really full and alive".

Martin said that if decision of the track listing has been left entirely to the band members, the album would have comprised 10–12 songs, but they received advice from the record label and producers to keep it more concise.

A deluxe edition was released on two vinyl records, with a pressing on transparent orange and turquoise discs, a black and white sleeve, and autographs of the band members.

"[14] Damien Morris of The Observer said the album saw "the band's gift for melody and grasp of pop's dynamics tweaked into transcendent shapes" by Zdar and McDonald.

[17] Pitchfork's Jonah Bromwich said, "it's compulsively listenable, oddly moving, and stranger than it first appears, as the band gets existential on the dance floor."

"[13] Stephen Worthy of Mojo commended Hot Chip for their choice of producers and said the band "remain ruthlessly consistent and relentlessly reliable".
