Custom Marble Bathrooms and Basins
Studio IB Milano designs and produces custom marble bathrooms, bathtubs and basins, carved by specialist Italian artisans and shaped around a single room, a single client and a single piece of stone.
A room built from one material
Marble bathrooms designed as a single volume.
A custom marble bathroom rarely begins with a catalogue. It begins with the room itself — its proportions, its light, the way a client moves through it — and with a decision about which stone will carry that atmosphere. From Milan, Studio IB Milano designs bathrooms, bathtubs and washbasins where floor, walls and fittings are considered together rather than assembled from separate parts.
We work on private residences internationally, often producing a single sculptural piece, such as a carved basin or a solid stone bathtub, for a specific bathroom, alongside full renovations where the entire room is conceived as one continuous material gesture.
The offer
Our marble bathroom services.
From a single custom marble basin to a complete bathing room, each commission is developed around the space and stone in question.
Custom Marble Basins
Freestanding or wall-mounted washbasins carved by hand from a single block of marble or natural stone.
Full Bathroom Design
Complete bathrooms where floor, walls, vanity and fittings are designed together in a coherent material language.
Material & Stone Selection
Guidance through marble, travertine and natural stone, matched to the light and scale of your specific bathroom.
Book-Matching & Veining
Careful selection and cutting of slabs so veining aligns across walls, floors and fitted stone surfaces.
Fittings & Detailing
Coordination of brass and chrome fittings, shelving and lighting to complement the stone rather than compete with it.
Materials
Choosing the right stone for a wet, intimate room.
A marble bathtub or basin is judged as closely as any piece of sculpture, and it is also lived with daily, so material choice has to satisfy both. We consider veining, porosity and finish together with the practical realities of a bathroom, selecting stones such as travertine, Calacatta and Carrara marble according to the character and use of the room.
Every luxury marble interior in a bathroom setting is finished by hand, honed or polished to a level that suits both the light of the room and the way the surface will be touched and used over time.

Made in Italy
Italian craftsmanship, international commissions.
Every marble bathtub in Italy that leaves our studio is carved and finished by specialist artisans working with techniques refined over generations, using tools and judgment that no machine can fully replicate on a material as variable as natural stone.
While the carving happens in Italy, our bathrooms are installed in private residences around the world. We coordinate design, production, shipping and installation as a single service, so a client abroad receives the same attention as one in Milan.
Questions
Frequently asked questions.
Can you design a single custom marble basin, or only a full bathroom renovation?
Both. Many commissions are for one sculptural piece, such as a freestanding basin, set into an existing bathroom, while others involve designing the entire room from floor to fittings.
How long does a custom marble bathtub take to produce?
It depends on the design, the stone and whether book-matching is required, so we discuss realistic timelines during the consultation once the brief is clear.
Which stones do you recommend for a bathroom?
It depends on the room's light, ventilation and how it will be used. We typically discuss options such as travertine, Carrara and Calacatta marble, weighing their veining and finish against the practical realities of a wet room.
Do you handle installation, or only design and carving?
We coordinate the full journey, including careful delivery and on-site installation, working alongside plumbers and other trades where needed.
Can you match veining across the bathtub, basin and walls?
Yes, book-matching and careful slab selection are part of our process when a client wants the stone to read as one continuous surface across the room.
Do you take on bathroom projects outside Italy?
Yes. While our craftsmanship is Italian, we regularly design and deliver custom marble bathrooms for private clients internationally.
