The Bath of Leo VI was a palace bath attributed to Emperor Leo VI, described in detail by Leo Choirosphaktes in an ekphrasis. The building featured a long entrance hall and a main chamber with a hot pool in an octagonal niche (octaconch), topped by at least one dome and an apse. The exterior may have been decorated with gilded stonework and statues, possibly reused (spolia). It likely incorporated remnants of the Theodosian-era imperial oikos of Marina, suggesting its location at the northeastern edge of the Great Palace, where it was supplied by the Hadrian Waterway.
Scholars like Magdalino identify this bath with the "Bath of the Oikonomion" mentioned in the Patria, while Mango argues it was a restoration of an earlier 5th-century private bath for the House of Marina. Choirosphaktes’ ekphrasis, commissioned by Constantine VII Porphyrogenitos, provides a vivid literary account of the bath’s grandeur. Today, its exact location and remains are uncertain.
