DIY Bathroom Sink from Vintage Bowl

In the middle of my small guest bathroom makeover, I decided to go for the custom vanity from a washstand. Naturally, that meant I needed a bathroom sink to match. Historically speaking, washstands would have had a water pitcher and bowl atop. And here enters the bathroom sink from a vintage bowl epiphany.

A DIY Sink Perfect for a Small Bathroom

It feels like every DIY project requires a heavy bit of problem-solving. Like the fact that this washstand is only 17″ deep. There are very few vessel sinks that will fit a countertop that is that shallow. Not to mention the cost.

You would think a small porcelain sink would be less expensive, but you’d be wrong. But I purchased the least expensive one I could find that would fit for $60 used on Amazon.

I had full intentions of using that sink until I was walking through a thrift store and happened upon this beautiful bowl, a vintage bowl for a mere $8. And like every true DIYer I thought to myself, “Why not make my own sink?”

Smaller Bathroom Statement Piece

In small bathrooms, you kind of have to be really careful about how much you add as far as statement pieces, colors, and patterns. It’s really easy to actually make them feel smaller.

And that is one thing I have struggled with in this bathroom design. I tend to be on the extra side of things. And then I hate it when I’m done because my tastes are actually more neutral.

That’s what happens when you try to push yourself to try things. You follow what you believe is a good idea and sometimes it doesn’t turn out as you hope. But I know I’ve struck gold this time!

Supplies

There’s a first time for everything and I will be honest that I have never drilled a hole with a diamond hole saw to create a bowl sink. But I have used diamond drill bits to make holes in glass. So, I was somewhat familiar with the process.

Two great things about this entire project are its simplicity and speed, it literally took me five minutes. The best thing about this whole project was the total cost, which was $24 total, $8 for the bowl, and $16 for the bit.

Step One – Measuring to Mark the Center

Initially, I tried marking the middle of the bowl inside but quickly learned drilling a hole that way was not the easiest. So I flipped the bowl upside down, measured that, and marked dead center.

  1. Turn the bowl upside down.
  2. Measure the total width of the bottom.
  3. Mark the center with a pencil or marker.

Note: If I had been smarter and thought this through a bit more I would have created a guide jig from the bottom of the bowl and drilled a hole in the center to keep my drill bit steady during the drilling.

Step Two – Drilling the Hole for the Sink Drain

This part was a hair trickier and was definitely made easier with a second pair of hands. However, I didn’t have any guide jig to keep my drill bit from moving around while I was drilling. If I had made or purchased a guide jig I could have easily done this myself.

  1. Add some cold water to where you’ll be drilling.
  2. Put your guide in the center.
  3. Applying a small amount of pressure, start your drill.
  4. The bit may slip because wet porcelain is slippery. Do your best to keep it steady. Or stop and readjust it.
  5. When the water gets cloudy (the porcelain dust will cloud the water) dump it out and add fresh cold water so you can see. You may have to do this 2-3 times.
  6. Then you will feel the porcelain layers breaking down.
  7. Don’t push down, let the drill bit do the work. Just hold it in place. Applying pressure once it’s gripped the porcelain could chip the bowl as it comes through the top.
  8. Slow and steady wins the race.

Note: Measure your sink drain at the largest point that will pass through your bowl into your vanity to ensure you purchase the correct hole saw size.

Troubleshoot: Mine was slightly too small, if this happens to you don’t worry you can easily use the hole saw drill bit to sand the inner circle of the hole down. This will slowly make the hole larger. Simply run water and slowly go in a circular motion applying pressure on the edge while you circle.
