Suntub is the second studio album by Danish musician ML Buch, released on 27 October 2023 through 15 Love.

Philip Sherburne of Pitchfork stated that Suntub "focuses on more abstract and corporeal themes" than Buch's debut album Skinned (2020), and replaces that album's "overtly electronic elements" with "sparkling guitars, frictionless rock drumming, and vocal melodies rendered with airbrushed clarity".

Sherburne concluded that "Outwardly, Suntub is so glossy that it suggests a kind of normcore, a pastiche of gentle alt-rock.

ranked the album the ninth best album of 2023, with the publication's Kaelen Bell describing it as "pastoral art rock imbued with heaving, sticky humanity, a place where past and present collide constantly to create entirely new forms" as well as having a "MIDI-warped landscape, an alien environment sketched in silvery riffs and dewy electronics".

[5] Gorilla vs. Bear ranked it the second best album of 2023, calling it "the most soothing and unsettlingly beautiful record of the year" that "envelops the listener in an otherworldly cocoon by tapping into some uncanny, unshakeable deja-vu" and "feels very real, like a gleaming, half-remembered soft-rock mirage you keep hearing in your warmest, fuzziest dreams".
