Question & answer
How Heavy Is a Farmhouse Sink?
Heavy enough to need real support. The BOCCHI 30-inch fireclay listing gives 76.81 pounds for the sink. We couldn't find stated weights for our other picks, so look on the listing for the exact model before the supports are built.

The short answer
The BOCCHI Classico 30-inch fireclay sink is listed at 76.81 pounds, and 98 pounds in its box. That's the one figure we could read among our picks. Weight varies with size and material, and larger fireclay or cast iron sinks can weigh more. The Sink Boutique says farmhouse sinks are heavy and need a support structure inside the cabinet.
On this page
Few makers we read print a weight on the sheet, which is odd for something this important. Here's what we could find.
The figures
| Sink | Material | Weight we could read |
|---|---|---|
| BOCCHI Classico 30 | Fireclay | 76.81 lb, or 98 lb in its box, per retailer |
| Ruvati RVL2300WH | Fireclay, 1 in thick | Not on the page we read |
| KRAUS KHF200-33 | Stainless steel | Not on the papers we read |
| Kohler Whitehaven K-6489 | Enameled cast iron | Not on the sheet we read |
Don't take the BOCCHI figure as typical of bigger sinks. Ask the seller or look on the listing for your exact model.
Why it matters
The sink doesn't hang from the counter. Signature Hardware says it rests fully on its support. The Sink Boutique says a support structure has to be built because these sinks are heavy. Magnus says cast iron especially needs internal cabinet supports.
That support also has to carry what's in the sink, meaning water and dishes as well. Tell whoever builds it the sink's weight and that it will be full at times.
What to do
Our install overview shows where the supports go, and existing cabinets explains the rest of the cabinet work. The material matters a lot here, as fireclay vs stainless steel explains. If you're also planning a disposal, see farmhouse sinks and disposals. To see the sink with the published weight, here's the BOCCHI Classico 30*.
Asked before buying
Do I need supports for a stainless steel farmhouse sink?
Yes. Steel isn't exempt. KRAUS's manual has you build supports for its stainless farmhouse sinks, naming angle irons, 2×4s and plywood. Signature Hardware says farmhouse sinks rest fully on their support and aren't attached to the counter, and it doesn't make an exception for steel.
Can one person lift it?
We can't answer that for you, and no source we read rates it. A sink listed at 76.81 pounds is awkward to handle on your own, especially while it's being set level inside a cabinet. Plan on help, and ask your installer.
