Love the bowl layout

Two bowls are great: wash on one side, rinse on the other. Shows water spots like any stainless, but a quick wipe and it looks new. Would buy again.

Tight fit

Instructions are clear even for a first-timer. The 15mm corner radius is a good middle ground: modern look, and easy to clean. The CSA mark mattered to us - our inspector checked it no problem. One small thing: it took all of our 33 inch cabinet - a tight squeeze, so measure first. Stainless shows hard water spots if you don't wipe it down - normal, but worth knowing.

Fair price

At this price, we were pleasantly surprised. Undermount, so I wipe crumbs right into the bowl - no rim to clean around. 18 gauge is more than enough for our use and keeps the cost down.

Exactly what we needed

Faucet is sold separately, as listed - we picked our own. The 15mm corner radius is a good middle ground: crisp look, but nothing gets stuck in the corners. Undermount, so we sweep crumbs right into the bowl - no rim to catch anything.

Great look

Design 5 · Size 3 · Color 5 · Price 4
Clean modern lines fit our space. The one catch: with two bowls in 30 inches each side is narrow - our roasting pan doesn't fit flat. Not the cheapest, but worth it.

Solid, one complaint

Just installed it - first impressions are mixed. Two strainers included for the price - good value. One small thing: looks fine, just plainer than I hoped. At 10 inches it's really deep - I feel it in my back after a big wash. Overall decent.

Mostly happy

At 30 inches wide it fit our 33 inch base cabinet just right. The finish didn't work in our kitchen - it looked different than I pictured. 18 gauge is lighter than a 16, but no issues so far.

Frequently asked about this product
Q
What size base cabinet do I need for this sink?
Frequently asked
A
Fits a base cabinet at least 33 in wide. The sink itself is 30 in wide, 18 in front to back and 10 in deep - these are outside (rim) measurements, the same ones in the product title.

Q
Is this an undermount or a drop-in (top-mount) sink?
Frequently asked
A
This is an undermount sink, installed from below the countertop; the installation instructions are in the box.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
How many bowls does it have?
Frequently asked
A
Two bowls.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
How many faucet holes does it have?
Frequently asked
A
None on the sink itself. As an undermount sink it has no deck, so the faucet mounts through the countertop behind it - drill the countertop for your faucet (1 hole for a single-handle faucet, more if it has a side spray or soap dispenser).
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
Does it come with the drain / basket strainer?
Frequently asked
A
Yes, the drain assembly (basket strainer) is included in the box - one for each bowl.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
Does a cut-out template come with it?
Frequently asked
A
Yes, the full-size cut-out template is in the box. Wait for the sink to arrive and check the template against the actual sink before cutting the countertop - the cut-out is the one thing that cannot be undone.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
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
Was this helpful?Yes 0 No 0
Q
How deep is the sink?
Frequently asked
A
The sink stands 10 in tall overall (rim to the bottom, outside measurement). 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
Was this helpful?Yes 0 No 0
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, so the rim stays hidden under the counter; your fabricator chooses the reveal. Do not cut from the title dimensions.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
What gauge is the stainless steel?
Frequently asked
A
18 gauge stainless steel - the standard thickness for residential kitchen sinks.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
Are the bowl corners square or rounded?
Frequently asked
A
The bowl corners have a 15 mm radius - a tight, near-square modern look that is still easy to wipe clean.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
Does it have an overflow?
Frequently asked
A
No. Kitchen sinks do not have an overflow opening (that is a bathroom-sink feature); use a faucet with a reasonable flow and the basket strainer to control the water level.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
Will it scratch, stain or rust?
Frequently asked
A
Fine hairline marks from pots and cutlery are normal on any stainless sink and blend into the finish with use; a bottom grid protects the base from heavy pots. Stainless steel does not rust in normal use. Rinse and towel-dry after use, clean with dish soap or a stainless cleaner wiping with the grain, and keep steel wool, bleach and chlorine cleaners off it.

Q
Is it certified for use in Canada and the US?
Frequently asked
A
It is CSA certified, which is what Canadian plumbing inspectors look for at final inspection. For a permitted installation in the United States, check whether your inspector asks for the cUPC mark specifically before ordering.
Warm Bath Tiles team
Was this helpful?Yes 0 No 0
Q
Who makes this sink, and where is it made?
Frequently asked
A
It is our own house-brand sink, manufactured in China to our specification. We are the importer, not a reseller: every box is opened and inspected at our warehouse before it ships, and the quality-audit photos are available with your order.
Warm Bath Tiles team

Q
How fast will it arrive, and is shipping free?
Frequently asked

Warm Bath Tiles team
Q
Will I pay duties or customs on a cross-border order?
Frequently asked
A
No. We are the shipper of record, so any customs duties or import fees on a cross-border order are paid by us - nothing extra is charged at delivery.
Warm Bath Tiles team

A
Yes, within 30 days of delivery, as long as it is new, uninstalled and in the original packaging. For a change of mind a 35% restocking fee applies and the buyer pays the return shipping. Damaged, defective, wrong or missing items are replaced or refunded with no fee and free return shipping - inspect the box at delivery and send us photos within 24 hours.
