Smart rear drain

Rear drain frees up a lot more cabinet space for cleaning supplies. Handmade construction looks great: straight lines and neat seams. Satin finish has a soft sheen and matches our stainless appliances. Instructions are easy to follow for a DIY install. No faucet holes in the sink, so we mounted our faucet where we wanted.

Easy install

The template that comes with it made our fabricator's job easy. If I had to nitpick: 18 gauge is lighter than a 16, but no issues so far.

Perfect fit for our 36 inch cabinet

A month in and it still looks great. 31.5 inches is a great width for our kitchen. The faucet goes in the counter, so we put the pull-down faucet where we wanted. Undermount, so I sweep crumbs right into the bowl - no rim to catch anything. Drain at the back means a plate sitting in the bowl doesn't block it. Exactly what we wanted.

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); the bowl is 9 in deep inside. 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.

Frequently asked
Q
Does it have an overflow?
Frequently asked
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.
