Cirenne BT-139A is an OIXDESIGN made-to-order architectural round freestanding soaking bathtub presented in Portoro Black Marble. The disciplined circular soaking vessel is extended by an integrated external side ledge / wing for a strong sculptural, directional silhouette.
Cirenne combines round geometry with an asymmetric side feature that gives the tub a furniture-like architectural profile. Portoro Black Marble varies naturally in deep black background, pale-to-gold mineral veining, direction and contrast. Available stone can be reviewed before fabrication.
The supplied drawing indicates approximately 1600 mm overall diameter, 650 mm overall height, an approximately 125 mm rim and a centered drain. Final body and side-ledge geometry, drain interface, overflow configuration, wall thickness, tolerances, verified weight and water capacity are confirmed on the approved project shop drawing.
Diameter, height, basin proportions, rim treatment, side-ledged detail, finish and drain coordination may be reviewed for feasibility. Structural loading, waterproofing, access, lifting route and plumbing rough-in should be coordinated before fabrication.
The finished bathtub is protected and secured in a reinforced export crate for heavy-freight transport. Indoor placement, crane service, rigging, final positioning, plumbing and installation are excluded unless specifically quoted.
Use a pH-neutral marble-safe cleaner with a soft cloth or non-abrasive sponge. Avoid acids, harsh descalers and abrasive pads. Sealing guidance should match the approved stone and finish.
OIXDESIGN supports stone review, custom sizing, finish coordination, shop drawings, production planning, reinforced export packing and destination logistics.
Reference dimensions are for preliminary coordination. Final fabrication is based on the approved project shop drawing.
