For our latest lookbook, we've collected eight bathrooms with decorative sunken baths that create a relaxing atmosphere.

Sunken baths are bathtubs that have been sunk into the bathroom floor, decks or patios. They can help to save space in the bathroom and to create a luxurious spa-like feeling.

In this lookbook, we've gathered inspirational sunken bathtubs in homes from South Korea to Ukraine, including a peaceful sunken bath on a wood patio and a bath clad in green tiles.

This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks featuring offbeat bakeries, minimalist Tokyo apartments and interiors with natural materials and timeless accents.
