12 Solid Stone Bathtub Designs

12 solid stone bathtubs carved from a single block of marble, granite or basalt - every shape in our catalogue, with real weights, materials and finishes for planning your bathroom. A stone bathtub isn't a fixture you order from a brochure and forget about until delivery - it's a 300-800 kg carved object that has to be planned into the room, the floor structure and the plumbing before a single block is cut. Here's the full range we carve, so you can see what's actually possible before you start sketching a bathroom around one.

What "solid stone" actually means here

Every tub below is hollowed from a single block, not cast, moulded or veneered - the same carving process behind our Stone Articles furniture and basins. That's why weight matters so much: most run 300-800 kg, and the two marble tubs lower down this list are lighter only because a smaller block is used. Floor loading, access route and plumbing rough-in all need to be confirmed with your contractor before production starts, not after the tub arrives on site.

The twelve shapes

01. Oval Bathtub

A clean, symmetrical oval profile carved from a single block, with an evenly polished interior and a choice of honed or polished exterior - the most versatile shape in the range and our usual starting recommendation. Marble, granite, basalt or sandstone; estimated weight 300-800 kg.

02. Round Bathtub

Turned from a solid cylindrical block into a true circular soaking profile, deep enough for full immersion, with a polished interior and honed exterior. Suits a symmetrical bathroom layout where the tub can be approached from more than one side.

03. The Gondola Bathtub

Named for its silhouette - a long, low tub with softly upturned ends like a boat hull, giving generous interior length for full reclining. One of the better choices where the bathroom is long rather than square.

04. Still Water Bathtub

The most restrained tub in the collection - flat honed faces, a wide flat rim and no applied carving, designed to disappear into a minimal bathroom rather than announce itself. The one to specify when the room should stay quiet.

05. The Void Bathtub

Pairs a plain, unbroken exterior with a deep, dramatically hollowed bowl - the emphasis entirely on interior volume rather than surface carving. A good option where the tub is seen mostly from above or from the doorway.

06. Wave Bathtub

Carries a rippling, water-like texture across its outer face, carved in shallow relief so the tub reads as movement even when empty. Interior left smooth and polished - the exterior carving is the whole point here, so give it room to be seen.

07. Fluted Bathtub

Fine, evenly spaced vertical grooves run around the full exterior, referencing the fluted columns used elsewhere in our furniture range - see the same language in our consoles and side tables. Interior left smooth and polished.

08. Sculpted Bathtub

Departs from the oval or rectangular tub entirely - the rim and base are carved to a freeform silhouette that reads as sculpture as much as fixture, with the interior hollowed and polished for comfort. For a bathroom that's meant to feel like a gallery.

09. Volcanic Bathtub

Left with a natural, textured exterior finish that shows the stone's own volcanic origin, softened only where the body meets the water line. Carved in basalt or granite - the most raw-looking finish in the range, intentionally.

10. Basalt Bathtub

Carved from a single block of dense black basalt, hollowed to a deep soaking profile and finished with a honed exterior. The heaviest tub we make, up to 800 kg - confirm floor loading early if this is the one you want.

11. Verde Majesty Bathtub

Carved from a single block of green marble, hollowed and polished to a shell-like interior with a natural, veined exterior. Every block is different, so every tub is genuinely one of a kind - estimated weight 300-400 kg, lighter than the basalt and granite tubs above.

12. Verde Antico Bathtub

Carved from a dense, dark green marble with heavy natural veining, giving a more dramatic and antique character than Verde Majesty. Also available in set sizes rather than custom-only, if you want to confirm dimensions before the design stage.

Planning around the weight

The single detail that changes every other decision here is weight. A 300-800 kg tub needs a structural floor, a confirmed access route from the entrance to the bathroom - stairwells and doorway widths matter more than people expect - and plumbing set against the specific tub's drawing rather than a generic template. We go through the same planning logic for basins in choosing a stone basin for your bathroom, and it applies here at a larger scale. Material also affects long-term care: marble is the most porous of the options and benefits from sealing near constant water contact, while granite and basalt are denser and more forgiving day to day - the same logic we cover in sandstone vs limestone for cladding applies across stone types generally.

If you're planning a bathroom around one of these, send us the room dimensions and access route and we'll confirm which shapes are realistic before you commit to a layout.
