Luxury Principal Bathroom with Green Onyx-Effect Porcelain and Dark Walnut Veneer

We paired the luxurious sheen of green onyx-effect porcelain slabs with warm walnut panels and a monolithic white Corian basin. A slim black-framed corner shower, a backlit mirror, a vertically fluted lacquered drawer and concealed niche lighting bring layered spa ambience and sculptural residential elegance to the principal bathroom.

We aimed to create a restorative hotel-suite bathroom in a compact space by balancing the strong dramatic character of onyx with rich walnut. Full-height concealed walnut storage and a monolithic floating basin reduce clutter, while sculptural light layers and clear shower glass create timeless luxury.

Design Decisions That Transform the Space

This bathroom blends the dramatic elegance of natural stone with richly textured timber. Glossy green onyx-patterned porcelain slabs in emerald/aqua tones meet deep walnut panels and a monolithic white Corian/solid-surface basin. A slim black-framed corner shower, a vertically fluted lacquered drawer, a rectangular backlit mirror and concealed light lines turn the compact bathroom into a sculptural, restful residential spa.

Material and Colour Balance

Large-format glossy green onyx-veined porcelain tiles / slabs cover the floor and main walls, adding depth and mineral sheen.

Warm dark natural walnut veneer on the shower rear panel and full-height storage above the toilet balances the cool green reflections.

A seamless, matt, non-porous one-piece white Corian / solid-surface floating top includes an integrated basin.

An off-white / cream vertically fluted lacquered drawer front adds crafted texture, with an open towel compartment on the left.

A vertical rectangular mirror with a slim black metal frame has even warm 3000K LED backlighting.

A cylindrical black-bodied tube pendant with smoked/amber glass hangs to the mirror’s left.

Concealed warm linear LEDs illuminate the walnut shower niche and the niche beneath the timber cabinet above the toilet.

A deck-mounted twin-control polished chrome / stainless-steel basin tap is paired with chrome and metallic-grey shower, bidet-spray and flush-plate details.

A clear-glass corner shower enclosure has matt-black aluminium profiles.

A minimalist white rimless wall-hung toilet and an organically shaped chocolate-brown shaggy bath mat complete the room.

Technical and Architectural Design

Wet and Dry Balance: The corner shower contains splashes while clear glass preserves the visual continuity of the green onyx texture.

Recessed Shower and Storage Compartments: A shampoo niche within the walnut shower panel and timber cabinets above the cistern provide discreet storage in the compact space.

Floating Vanity Lightness: The wall-mounted monolithic basin, open towel compartment and fluted drawer leave the floor visible and make the room feel larger.

Integrated Falls and Linear Drainage: A concealed linear drain provides an unobtrusive drainage solution within the onyx-effect porcelain shower floor.
