Plan for the counter

A year and a half in - it's fine overall. Deep enough at 9 inches that the sprayer doesn't splash everywhere. Undermount needs a stone counter - our laminate plan had to change, so plan for that. Cost was a little more than I wanted to spend.

Certified and solid

A month in and it still looks great. CSA certified mattered to us - our inspector checked it without questions. Undermount, so I wipe crumbs straight off the counter into the sink - no rim to catch anything. The instructions were clear for a DIY install.

Excellent sink

Two years in and still love it. No faucet included, which I knew going in - we picked our own. We waited for the sink to arrive before cutting, as the listing suggests - good advice, the template was spot on. Not the cheapest, but worth it. Would recommend.

Love the low divider

Just installed it and it looks great. The lowered center divider is the best part - a long baking sheet sits across both sides. The faucet goes in the counter, so we put our faucet where we wanted.

Great value

At this price, I expected less. The faucet goes in the counter, so we put our faucet where we wanted. We measured carefully and the 30 inch width was exactly what our 33 inch cabinet needed. The grey is a great neutral that goes with everything.

Deep enough

Upgraded from a chipped sink. Deep enough at 9 inches that I rarely splash the counter. Love it.

Disappointed
Grant C. · Virginia Beach, VA · Mar 9, 2026 · 7:48 PM
Design 3 · Size 3 · Color 1 · Price 1
A year and a half in and it's not what I hoped. The finish didn't work in our kitchen - not what I pictured. It felt overpriced for a sink this size. Looks ok, but plainer than I hoped. With two bowls in 30 inches each side is on the small side - the griddle doesn't fit flat.

Love the bowl layout

About a year in and still love it. Glad we went with the double bowl layout - I can prep while dishes soak. Instructions were clear.

Sits seamless under our quartz counter. Two strainers included at this price - great value. Love the two bowl setup - I can prep while dishes soak.

Put this in at the cottage. The instructions were easy to follow for a DIY install. The grey is a nice neutral - not too dark, not too light. Great sink.

Frequently asked
Q
Does it work with a garbage disposal?
Frequently asked
A
Yes. It has the standard 3-1/2 in kitchen drain opening that household garbage disposals mount to; the disposal's own flange replaces the basket strainer on that bowl. Each bowl has its own opening, so you can put a disposal under one bowl and keep the strainer on the other.
Warm Bath Tiles team
Q
How deep is the sink?
Frequently asked
A
The sink stands 9 in tall overall (rim to the bottom, outside measurement); inside it measures 28 x 16 in and is 8.5 in deep. The usable depth once installed is the inside depth, plus the thickness of your countertop above the rim on an undermount. Check it against the drain and disposal you plan to use so the trap still fits in the cabinet.
Warm Bath Tiles team
Q
What size is the countertop cut-out?
Frequently asked
A
Use the full-size template in the box - it is the exact cut line. For an undermount the opening follows the inside of the bowl (about 28 x 16 in), so the rim stays hidden under the counter; your fabricator chooses the reveal. Do not cut from the title dimensions.
Warm Bath Tiles team
Q
Does it have an overflow?
Frequently asked
Q
How do I clean it, and will it chip, stain or fade?
Frequently asked
A
Granite composite is a dense mix of natural stone and acrylic resin, so it resists scratches, chips, stains and the heat of everyday pots. The colour runs through the full thickness and is UV-stable, so it does not fade. Clean with warm soapy water and a soft cloth; a paste of baking soda lifts hard-water marks. Avoid abrasive powders, scouring pads and undiluted bleach.
