Premium T-304 Stainless Steel
Allora USA sinks use premium T-304 stainless steel in a range of thick gauges (22–16G) for enhanced strength, corrosion resistance, and a quality look and feel that stands up to daily use.

Advanced Soundproofing
Soundproofing technology features thick rubber pads to absorb noise and reduce vibration, while an anti-condensation coating prevents moisture build-up, protecting cabinets below.

Durable PVD Finish
The PVD color finish bonds securely to the steel, offering superior resistance to scratches, chips, and corrosion. The sandblasted matte texture resists water spots and fingerprints, making upkeep easy.

Integrated Waterway Channel
The integrated waterway channel directs water straight to the drain, even when full, preventing standing water and improving drainage.

The Perfect Depth
Our deep sinks are spacious enough to accommodate large pots and pans, but won't interfere with conventional plumbing underneath the sink.

TECHNICAL SPECIFICATIONS
At Allora USA, we provide a variety of 3D design files and resources tailored to streamline your specification journey.

FREQUENTLY ASKED QUESTIONS
An undermount kitchen sink offers a sleek, modern look and allows for seamless countertop integration, making it easier to clean and maintain. Unlike top mount sinks, undermount sinks do not have a rim, which helps create more counter space and a contemporary kitchen aesthetic. They are a popular choice for granite, quartz, and solid surface countertops, enhancing both style and functionality in modern kitchen remodels.
The best materials for undermount sinks include stainless steel, granite composite, and fireclay. Stainless steel undermount sinks are durable, rust-resistant, and easy to clean, making them a top choice for high-traffic kitchens. Granite composite undermount sinks provide a scratch-resistant, heat-resistant surface, while fireclay undermount sinks offer a timeless, farmhouse-style aesthetic with excellent durability.
Undermount sinks work best with solid surface countertops such as granite, quartz, and marble, which provide the necessary support for a secure installation. They are not recommended for laminate countertops unless additional reinforcement is used. If you're planning a kitchen remodel, consult a professional to ensure your countertop material is compatible with an undermount sink installation.
To maintain your undermount kitchen sink, regularly clean it with a mild detergent and soft cloth to prevent stains and buildup. For stainless steel sinks, use a baking soda paste or a vinegar rinse to remove water spots and maintain shine. For granite composite and fireclay sinks, avoid abrasive cleaners and instead use a non-acidic cleaner to preserve the finish. Keeping the sink edges and mounting area clean will prevent mold and ensure long-lasting durability.
