Stone resin undermount ramp sink, 48.8 x 16.1 x 5.3 in, matte or glossy white.

The Badeloft undermount ramp sink UB-04-XL is an extra-large ramp sink in white. Our largest ramp sink is over 4 feet in length and more than 16 inches wide, making this an ideal choice for commercial restrooms and master bathrooms. Ramp sinks are popular choices for contemporary and minimalist spaces. Their seamless edges blend into the countertop with modern elegance, and their lack of cracks and creases ensure easy cleaning. Badeloft is the sole provider of undermount ramp sinks in the USA.

Badeloft sinks are made of a durable stone resin. This blend of natural marble and limestone is cool to the touch and an excellent insulator. Damage resistant and non-porous, stone sinks last decades with little to no maintenance required. This ramp sink comes in your choice of a hand-buffed finish in matte or glossy white. It includes two invisible drain slots and hardware for installation.

05Why it lasts

Details that matter.

Badeloft details portrait 2026 | UB-04-XL | 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.

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.
