Construction of Sky Lagoon began in early 2020 and was completed in 2021.[1] The design was inspired by the Icelandic geography and uses grey-blues, deep greens, whites and creams to copy the landscape.[1]

Some elements of Sky Lagoon were inspired by Icelandic nature and heritage, such as the turfhouse, turf walls and plunge pool.[2] Elements of the facility include a cave tunnel entrance to a hot springs soaking pool and a cold plunge.[3]
