33-7/8" Double Bowl Undermount Sink For Seamless Laminate and Solid Surface Kitchens
The Karran E-550 is an 18-gauge stainless steel double bowl kitchen sink built for seamless undermount installation in laminate and solid surface countertops. Part of the Edge 500 series, it delivers a flush, seam-free surface transition that makes cleanup straightforward and gives the counter a continuous, finished look.
Key Features
• Seamless Edge rim bonds flush with laminate and solid surface countertops so no exposed seam or raised edge remains at the sink line.
• Equal double bowl layout divides the 33-7/8 inch sink into two matched basins for a balanced wash-and-rinse or two-task workflow.
• 18-gauge stainless steel construction provides solid, dent-resistant walls across both bowls and the full deck.
• 9-inch bowl depth accommodates tall pots and full sheet pans without straining over a shallow basin.
• Undermount installation keeps the counter wipe-clean to the bowl edge with no rim to trap food or water.
Where This Sink Earns Its Place
The equal bowl configuration makes the E-550 a natural fit for kitchens that rely on a two-station approach: soaking and washing on one side, rinsing or drying rack on the other. The 33-7/8 inch footprint fits a standard 36-inch sink base, so it drops into new builds and kitchen refreshes without cabinet alterations. Because the Edge series is engineered specifically for laminate and solid surface countertops, it is the right call when a cabinet shop or homeowner wants an undermount look in a laminate top without compromising the countertop edge or the install warranty. Solid surface fabricators get the same seamless result with the appropriate adhesive and bevel-bit method.
Construction and the Seamless Rim
What sets the Edge 500 apart from a conventional undermount stainless sink is the rim geometry. A standard undermount drops below the counter and leaves a visible seam between the countertop and the bowl; the Edge rim is engineered to be trimmed and finished flush using Karran's documented fabrication steps, including seam adhesive and bevel-bit routing. The result is a counter surface that flows directly into the bowl. The 18-gauge stainless body delivers a brushed satin appearance across both basins, and the material is resistant to everyday kitchen use. For installations where the countertop finish matters as much as the sink itself, the seamless outcome is the primary reason to choose this series over a dropped-in or conventional undermount alternative.
Right Fit for Cabinet Shops and Kitchen Fabricators
Cabinet shops building laminate kitchens will find the E-550 straightforward to specify: a 36-inch base, standard plumbing rough-in, and Karran's Edge installation method are all that is needed. Fabricators working in solid surface have the same path. Contractors sourcing for a renovation where the homeowner wants an undermount appearance in a laminate countertop will find this sink resolves that common request cleanly. Designers specifying kitchens for multi-family or light commercial applications appreciate the consistent result the Edge method produces across units. The equal bowl split also avoids the handed orientation decision that comes with large/small bowl models, simplifying specification across a job.
Can this sink be installed in granite or quartz stone countertops?
The Edge 500 series is documented for laminate and solid surface countertops using Karran's seamless installation method. For stone countertops such as granite or engineered quartz, a conventional undermount approach is standard and a different Karran series is the right choice. Installing the Edge rim in stone would bypass the seamless process it was designed for.
Does the E-550 include a drain, grid, or mounting clips?
The E-550 ships as a bare sink. Basket strainers, bottom grids, and mounting hardware are sold separately. If you need a bundled pack, check whether a -PK1 version is available, which typically adds stainless basket strainers and a bottom grid to the order.
Where does the faucet mount on this sink?
The E-550 has no faucet deck, so the faucet, soap dispenser, and any other accessories mount through the countertop behind the sink. This is standard for the Edge undermount series and gives the fabricator control over hole placement and spacing.
What is the minimum cabinet size required?
Based on the 33-7/8 inch overall width, a 36-inch sink base cabinet is the standard fit for this model. Confirm the specific cabinet opening and countertop cutout dimensions against the actual sink and Karran's installation documentation before cutting.
A Seamless Result on the Day of Install
The E-550 is the answer when the countertop plan is laminate or solid surface and the result needs to look like the sink belongs there from the start, not like it was dropped in afterward. Two equal bowls, a 9-inch depth, and the Edge series rim give fabricators and contractors the combination they need to deliver a finished kitchen that holds up and looks right.
