An Undermount Vanity Bowl Built for Clean, Countertop-Flush Installations
The Durasein DLA360A is an oval, single-bowl acrylic undermount lavatory designed for bathroom vanities where a seamless, wipe-clean countertop edge matters. Its 100% acrylic construction is non-porous and stain-resistant, and the integral overflow keeps rising water in check without a separate add-on component. A solid choice for homeowners, designers, and fabricators working in solid surface vanity tops.
Key Features
• 100% acrylic, non-porous construction resists stains and supports easy daily cleaning without harsh chemicals.
• Integral overflow is built into the bowl, routing rising water to the drain before the basin spills.
• Undermount installation positions the bowl beneath the vanity top for a clean, rimless surface around the basin.
• Single oval bowl delivers an uninterrupted basin suited to compact and standard vanity installations alike.
• Arctic White finish (DM1001) offers a crisp, neutral tone that coordinates across a wide range of vanity top colors and faucet finishes.
• No added crystalline silica in the material, per Durasein's published silicosis bulletin (Zero Silica formulation).
Where This Bowl Fits in the Workflow
This sink is a natural fit for solid surface vanity fabrication. Because the bowl bonds to the underside of the deck, the countertop surface runs uninterrupted from back to front with no exposed rim collecting water or debris. The 1-3/4 inch drain opening accepts a standard lavatory pop-up drain — select the with-overflow version to match the bowl's integral overflow. The faucet mounts through the vanity top rather than through the bowl itself, so hole count and placement stay in the fabricator's or installer's control.
The integral overflow is built into the bowl body, which means no separate overflow kit to source or install. For projects where the drain assembly is being specified fresh, note that the drain assembly does not ship with this sink and must be ordered separately.
Material and Durability
Durasein describes the bowl as 100% acrylic — a non-porous, stain-resistant material that does not harbor mold or mildew in normal bathroom conditions. The surface can be renewed: minor scratches and surface marks respond to a Scotch-Brite pad and a non-abrasive cleanser, making this a practical choice in vanities that see regular use. Arctic White (DM1001) is a clean, true white that holds its appearance well in bathroom environments. Avoid abrasive scouring pads and prolonged exposure to extreme heat, consistent with Durasein's published care guidance for this material family.
Who Reaches for This Sink
Solid surface fabricators will find the DLA360A straightforward to bond into a Durasein or compatible solid surface top using standard seam-adhesive methods. Designers specifying a renovation get a clean oval shape in a neutral white that works across contemporary and traditional vanity styles. Contractors installing in new-construction bathrooms appreciate the integral overflow and the absence of deck holes, which simplify rough-in planning. Homeowners replacing an existing undermount bowl in a compatible cutout will want to verify their cutout dimensions against the nominal published measurements before ordering.
This sink is ADA compliant when installed in accordance with ADA guidelines, as stated by the manufacturer.
Frequently Asked Questions
Does a drain assembly ship with this sink?
No. The drain assembly is sold separately. Because this bowl has an integral overflow, you will need a pop-up drain specifically made for sinks with overflow — verify that before ordering the drain.
Where do the faucet holes go?
This bowl has no faucet holes. The faucet mounts through the vanity top above the sink, which gives you flexibility in hole placement and faucet style without the bowl dictating the layout.
Are the listed dimensions the exact finished size?
Durasein publishes nominal dimensions. The published 16-1/16 inch by 12-3/16 inch by 7-1/16 inch figures identify the size class; have the actual sink on hand before making your countertop cutout.
Can this bowl be bonded into a solid surface countertop?
Yes. A solid surface bowl bonds to a solid surface top with seam adhesive using a hard-seam method. For dissimilar countertop materials, silicone and mechanical fasteners are the standard approach — follow the fabricator's mounting guidelines for the specific top material.
What does "Zero Silica" mean for this product?
Durasein states there is no added crystalline silica in their solid surface material. The filler is alumina trihydrate bound in an acrylic polymer matrix. This is a material composition fact, not a health-outcome guarantee — the manufacturer's bulletin uses the phrase "Zero Silica" to describe the formulation.
