Arthur Premium Stainless Undermount/Drop-in Bathroom Lavatory Basin

Signature Features:

Heavy Duty Dual-Wall 18 Gauge Type 304 Stainless Steel Construction

Unlike thin single-wall stainless sinks, the Oasis Arthur is built with dual-wall (double-layer) 18 gauge Type 304 stainless steel for superior rigidity, strength, and long-term durability. Designed specifically for high-use commercial bathrooms, this sink stands up to constant abuse in gas stations, airports, restaurants, schools, medical clinics, and public facilities where lesser sinks simply fail.

2. True Integrated Overflow Channel

Most stainless lavatory sinks skip the overflow entirely — the Arthur does not. Its fully integrated overflow channel improves drainage safety, helps prevent flooding, and makes intentional drain blocking far more difficult. It also allows compatibility with standard pop-up drains included with most lavatory faucets, giving installers and maintenance crews more flexibility without specialty parts.

3. Damage, Crack & Vandal Resistant Design

Porcelain sinks look great… right up until someone drops a bottle, climbs on the countertop, or decides the sink should become a skateboard ramp. The Arthur stainless lavatory sink will not crack, shatter, or create emergency maintenance calls caused by broken ceramic basins. This durable commercial sink is designed for decades of dependable service with minimal replacement concerns.

4. Antibacterial Brushed Satin Easy-to-Clean Surface

The non-porous brushed satin stainless finish resists staining, scratching, bacteria buildup, and everyday grime while cleaning easily with virtually any commercial cleaner. Ideal for commercial, medical, hospitality, and high-traffic restrooms where appearance, sanitation, and fast maintenance matter every day.

5. Fully Universal Mount Installation

The Arthur offers true installation flexibility with both undermount and drop-in mounting capability. Install undermount for a smooth architectural appearance, or use as a drop-in sink with slim rim design that allows water and debris to be wiped directly into the basin. This versatility makes it an excellent choice for new construction, renovations, and replacement of damaged ceramic lavatory sinks.

The Commercial Sink Built for Real-World Abuse

When it comes to high-use commercial bathrooms, the Oasis Arthur Medium Stainless Lavatory Sink is built to handle the chaos that destroys ordinary sinks. Designed specifically for gas stations, fast food restaurants, airports, medical clinics, schools, city parks, and heavy-traffic commercial restrooms, this sink combines heavy-duty durability, easy maintenance, and versatile installation flexibility in one professional-grade package.

Constructed from dual-wall (double-layer) 18 gauge Type 304 stainless steel, the Arthur delivers exceptional strength while maintaining a clean, modern brushed satin finish that resists staining, scratching, bacteria buildup, and everyday wear. Unlike porcelain lavatory sinks that can crack, shatter, or create costly maintenance emergencies, this vandal-resistant stainless sink is designed for decades of reliable service — even when customers, kids, shopping carts, and “creative” restroom users put it to the test.

And yes — it includes a true integrated overflow channel, something surprisingly rare in stainless commercial vanity sinks. That means compatibility with standard pop-up drains included with most lavatory faucets, while also helping prevent accidental overflows and making drain blocking far more difficult.

Because maintenance crews already have enough surprises waiting for them every Monday morning.

Designed for Commercial Real World Applications

In busy public bathrooms, things happen fast. Customers drop bottles into sinks. Kids climb countertops. Drains get plugged. Porcelain cracks. Maintenance budgets disappear.

The Oasis Arthur was engineered specifically to survive these environments while still looking clean and professional year after year. The medium-size basin often allows the sink to replace damaged ceramic lavatory sinks without major countertop modifications, making it an excellent retrofit option for renovation projects and maintenance departments.

For maximum commercial code compliance, pair with our sloped top grid lavatory drain with overflow (Model GDBNWO) for the ultimate commercial restroom setup.

Timeless Oval Design with Everyday Practicality

The Arthur sink celebrates the timeless appeal of the classic oval lavatory sink with softly rounded walls that naturally guide water toward the drain for effortless cleaning and reduced splashing. Its smooth flowing curves create a refined appearance that works equally well in modern commercial projects, healthcare facilities, hospitality spaces, and upscale residential applications.

Built for real-world use, the non-porous brushed satin stainless surface maintains its appearance with minimal upkeep while resisting stains, scratches, corrosion, and daily abuse.

ADA & Commercial Compliance

Designed to meet ADA requirements for commercial applications when installed according to proper guidelines. A dedicated ADA version with a shallower basin depth is also available for floating vanities and installations requiring additional clearance or commercial code inspection compliance.

Installation Recommendation

For an installation that could probably survive the apocalypse, we strongly recommend installing with sink mounting clips or one of our poly-hybrid sink adhesives. This creates an exceptionally secure bond between sink and countertop while helping prevent movement or detachment over time.
