Sea Wave Granite Stone Bathtubs — Block-Hollowed Freestanding Units

Polished Sea Wave granite bathtubs, freestanding oval and round soaking units from 1500–1800mm, are hollowed from single blocks for hotel bathroom and master-suite layouts.

Sea Wave is a Chinese white granite with a bright light ground crossed by fine flowing gray veining — movement that reads softly across the long curved face of a stone bathtub without turning busy. As a dense siliceous igneous rock rated 6–7 on the Mohs scale, it carries standing water and daily wet use without the sealing regime and soft touch that marbled alternatives demand. Buyers most often plan the bath as part of a wider stone package, so the same production lot continues into carved Sea Wave granite wash basins and, for the rooms beyond, into Sea Wave granite pavers and steps.

Each freestanding tub starts as a solid block selected against the project lot, then hollowed on CNC and finished by hand until the interior, rim and exterior read as one continuous piece. Oval units around 1700×800mm are the standard choice for guest suites; round units near 1500mm diameter suit square rooms, and oversized lengths follow the drawing. The drain is drilled to the fittings list, with overflow positions set before production.

The bright white face with flowing gray lines keeps the freestanding oval form looking quiet rather than heavy, which is why designers specify it as the focal piece in neutral interiors. Glossy interiors shed water marks and wipe clean; a matte exterior is available on request for muted schemes, and no unit leaves the floor until it has been dry-fit with the specified waste and tap positions.

A bathing unit lives with standing water, soap films and bath oils, so the material has to be test-backed rather than just decorative. Sea Wave granite is batch tested for absorption, density and flexural strength. The very low absorption means a granite bathtub carries water continuously without staining or wicking, and the glossy interior rinses clean after a plain wipe-down.

Honed exteriors perform identically under test — the finish changes the look, not the physics. Routine care is mild soap and water, with an optional impregnator every few years; no special cleaners or annual sealing are required, and chips are virtually unheard-of in normal residential and hospitality use. If you are comparing bath materials during specification, our natural stone care guidance sets out the certificates and tolerances worth checking with any supplier.

Units leave our Shuitou factory through a controlled route: blocks are selected against the project lot, hollowed on CNC and by hand, finished inside and out, then dry-fit with the specified drain position before crating. Every piece rides in its own foamed cradle inside a fumigated wooden crate, with rim rails, corner protectors and padded bullnose edges so the ocean voyage from Xiamen ends with zero chipped arrises.

Orders scale from one sample unit for client approval through full hotel-floor container loads, with trial pallets flowing straight into repeat batches without re-approving the stone. Drawings are quoted within 48 hours, shapes can be confirmed with 3D samples before production, and minimum order is 100m² of stone per project with an 18–25 day production lead time plus 25–35 days of ocean freight from Xiamen.

For wellness suites and hero rooms, the same process scales up: oversized oval and round units are laid out from full blocks, with lengths and interior depths set from the architect’s drawing rather than a catalogue. These pieces are matched across the order so veining flows consistently between rooms, and each large granite bathtub is crated on its own pallet for the container.

Large pieces need floor load and access checked on site — a filled unit weighs well over a tonne, so we share finished dimensions and weight with the installer early. The same batch then continues into the room itself: Sea Wave thresholds, vanity tops and floor tiles keep the bathroom reading as one material from the door to the water, with every piece cut from matched blocks.

Developers furnishing full villas or show flats commonly source the complete wet-room package from one factory — the stone bathtub plus the Sea Wave granite wash basins for the same suite — which keeps veining, finish and documentation on one batch and one shipping schedule.
