About SinkPoint

What is SinkPoint?

SinkPoint is an independent, advertising-supported website about kitchen and bathroom sinks — the basin types and materials, the faucets and fittings that go with them, and a set of free calculators for the practical questions that come up when you’re buying, installing, or replacing one. It isn’t a plumbing company, a fixture retailer, or a manufacturer, and it isn’t affiliated with any brand, trade group, or plumbing code body it mentions.

Who is this site for?

Anyone working through a sink decision — a homeowner comparing an undermount to a drop-in, a remodeler pricing out a kitchen refit, or someone standing at the hardware store trying to work out whether a bowl will actually fit the cabinet underneath. Nothing to sign up for, and no plumbing background required.

What tools are actually on here?

Six, all free and listed on the tools page:

• The Water Usage Calculator estimates daily, monthly, and yearly household water use and cost from showers, flushes, the tap, dishwasher, and laundry loads.
• The Sink Installation Cost Calculator prices an installed sink from its mount type and material, plus labor and extras like a faucet, disposal, or plumbing changes.
• The Sink Capacity Calculator works out how many gallons or liters a bowl holds from its inside length, width, and depth.
• The Drain Slope Calculator finds the fall or percent grade a drain line needs for a given run, or checks a measured drop against the standard.
• The Dishwasher Cost Calculator shows what running a dishwasher costs in water and electricity, and how that compares with washing the same loads by hand at the sink.
• The Countertop Cutout Calculator gives the cutout dimensions — length, width, corner radius, and setback — for a drop-in or undermount sink.

How do the calculators actually work?

They’re arithmetic on the numbers you enter, not lookups against some database. The drain slope tool applies the standard 1/4-inch-per-foot fall to a run length you provide, or works backward from a measured drop to a grade. The capacity tool multiplies a bowl’s inside length, width, and depth, adjusted for a rounded versus square-cornered basin. The installation and dishwasher cost tools apply typical parts, labor, and utility-rate ranges to what you type in — they don’t pull live pricing feeds or know the specifics of your job.

Where do the numbers and standards come from?

Plumbing and fabrication conventions in ordinary trade use — the 1/4-inch-per-foot drain slope guideline, standard bowl geometry, and typical material and labor cost ranges. There’s no proprietary pricing database or live market feed behind any of it, and every result is a range or estimate, not a quote.

Is any of this professional advice?

No. Everything here is general informational content, not professional plumbing, structural, or contractor advice. Actual costs, code requirements, and fit depend on your property, region, and fixture; check figures with a licensed plumber, fabricator, or your local building department before you buy materials or cut a counter.

Is it really free?

Yes — every tool is free, with no account or paywall. The site runs on advertising, which is what pays for hosting and keeps it that way. Ad placement doesn’t change what a calculator tells you.

What’s the Sinks & Fixtures Museum?

A separate reference section, the Sinks & Fixtures Museum, with galleries on basin types, the materials they’re made of, and the faucets and fittings around them. Every entry, image, and fact there is drawn from Wikipedia and Wikimedia Commons, credited at the source.

Is there anything to read besides the tools?

Yes — the blog covers sink and fixture topics in more depth, and Learn has reference material that pairs with the museum galleries.
