05Why it lasts

Details that matter.

Badeloft details portrait 2026 | UB-04-L | White | Sink_Glossy_White__Camera_Angle_1.png

Solid stone resin

The same acrylic-and-mineral composite as our tubs. Non-porous, and resistant to stains and scratches.

Badeloft details portrait 2026 | UB-04-L | White | Sink_Glossy_White__Camera_Angle_2.png

Won't chip

A dense, solid surface that shrugs off daily knocks where ceramic would crack.

Quietly absorbent

The thick material dampens sound, softening the rush of water.
