Wallpaper - Undersea World

Our Undersea World wallpaper, created by Anastasia Geraseva, brings a dreamy maritime fantasy to life with a quiet, poetic character. A majestic blue whale glides through cool steel blue water, carrying a rocky island and a blue and white striped lighthouse on its back. Golden beams radiate from the lantern room into a starlit sky filled with soaring white birds, while delicate sea currents, schools of swimming fish, and a sunken sailing ship rest in the calm depths below. Produced as made-to-measure, PVC-free wall murals with a subtle physical paper structure, our design provides an enchanting focal point that sparks the imagination.

In the room

We love how this mural wallpaper creates a tranquil story across a room without feeling visually overwhelming. The composition centres the main narrative of the whale and lighthouse high in the upper half, leaving the flowing underwater currents and sunken ship across the lower portion. This makes it particularly well suited to a nursery, child's bedroom, or playroom, where lower furniture like cots, toddler beds, low toy chests, or reading benches will not conceal the central scene.

In a bedroom or vacation home, we would give this design an uninterrupted feature wall where the sweeping horizontal movement of the sea and the graceful arc of the whale have room to expand. The muted steel blue background gives the mural an enveloping presence that sits comfortably in both smaller, cosy spaces and larger bedrooms with generous natural daylight.

Styling it

To complement the whimsical yet calm mood of this design, we suggest pairing it with simple, relaxed furnishings that let the mural remain the primary visual element. Light natural wood tones, such as pale ash or light birch, work beautifully against the cool ocean palette, bringing gentle warmth into the room without competing with the illustration.

For textiles, soft off-white cottons, washed chambray, and muted denim blues echo the oceanic theme while maintaining a contemporary, uncluttered aesthetic. Keep decorative items understated; simple woven storage baskets, matte ceramic touches, and subtle warm ambient lamps will highlight the golden lighthouse glow when the daylight fades.

Colour combinations

The palette of our wallpaper is anchored by muted steel blue, slate, and deep navy tones, balanced by crisp white line work, soft sandy beige, and delicate touches of lantern gold.

When choosing paint colours for adjacent walls, skirting, or built-in joinery, consider soft off-whites, gentle chalky greys, or muted marine blues that pick up on the deep water tones. If you want to introduce a touch of warmth into the scheme, soft sandy neutrals or subtle ochre accents in cushions and rugs connect naturally with the rocky island and glowing lighthouse beam.
