Stainless Steel Bottom Grid Built for the QT-812 and QU-812
The Karran GR-6021 is a stainless steel bottom grid sized and shaped specifically for the QT-812 and QU-812 single-bowl sinks, sitting flush on the bowl floor to lift dishes off the surface and let water drain freely beneath.
Key Features
• Exact-fit design matches the bowl dimensions of the QT-812 and QU-812 sinks for a stable, rattle-free fit.
• Stainless steel construction holds up to daily wet-environment use without corroding or staining the bowl surface.
• Elevated grid profile keeps dishes, cookware, and utensils off the bowl floor so water drains freely beneath.
• Surface protection reduces direct contact between hard items and the quartz composite bowl bottom.
• Sold separately as a standalone accessory, compatible with both the top mount QT-812 and the undermount QU-812.
Where This Grid Earns Its Place
A large single-bowl sink like the QT-812 or QU-812 sees a lot of traffic — roasting pans, stock pots, sheet pans, and daily dishware all land in the same basin. Without a grid on the floor, that traffic means sustained contact between hard objects and the quartz composite surface. The GR-6021 breaks that contact cycle, giving every item a stable resting place while water moves below rather than pooling around whatever is sitting there. For shops running the QU-812 undermount or the QT-812 top mount in a high-use installation, this grid is a practical addition to a working sink, not just a finishing touch.
Material and Construction
Stainless steel is the right wire material for a permanently wet environment. It does not transfer rust or staining onto a quartz composite bowl, and it holds its shape under the weight of heavier cookware without flexing or deforming. The grid's wire pattern is open enough to let water fall through rather than pool on the grid itself, which keeps both the grid and the bowl floor cleaner between washes. The finish coordinates naturally with the stainless fixtures most kitchens or shop areas already have in place.
Who Orders This Grid
Cabinet shops and kitchen installers specifying a complete QT-812 or QU-812 installation often add the GR-6021 at the time of the sink order so the grid is on hand for delivery day. Homeowners and designers finishing a quartz countertop project find it an easy way to protect a significant investment in the sink. Because it fits both the top mount and undermount versions of the 812 bowl, the same part number works regardless of which mounting method the countertop and installation called for.
Frequently Asked Questions
Does the GR-6021 fit both the QT-812 and the QU-812?
Yes. Karran publishes this grid as compatible with both the top mount QT-812 and the undermount QU-812. The bowl dimensions are the same across both mounting styles, so one grid number covers both.
Is this grid included when I order the QT-812 or QU-812 sink?
No. The GR-6021 is a separately sold accessory and does not ship in the box with either sink model. It is ordered on its own.
Will the grid scratch the quartz composite bowl?
Stainless steel wire grids are a standard pairing with quartz composite sinks. The grid elevates items off the surface rather than resting flat against it, which is exactly what limits surface wear. If your sink came with rubber feet on the grid or you want extra caution, check whether bumpers are included with this model before ordering.
Can I use this grid in a different Karran sink of similar size?
Karran publishes fits-lists by model. The GR-6021 is specified for the QT-812 and QU-812. Using it in a different model is not something the manufacturer documents, and bowl dimensions and shape vary enough across models that fit is not guaranteed.
A Grid That Works as Hard as the Sink Does
The GR-6021 adds a layer of everyday protection to a sink that is already built to take heavy use, keeping the bowl floor in better shape for longer without changing how the sink works or looks.
