Fabulous Concrete Sink

Drum roll please….announcing the most fabulous bathroom sink!

Concrete Sink

Ok, ok I know you can’t tell exactly what’s going on here. The left side is the side that fits perpendicular against the wall and you would stand in front of the sink on the right side. It’s a tight workspace so I was limited to the angle I could take the picture from.

This is the sink in front of the future backsplash (don’t mind the marks, this is the back of the marble)…

I’m trying to decide if I should apply any color to the sink. I’m not going near acid stain for this. There’s a product called SoyCrete which is a Soy based stain that penetrates the concrete. It’s supposed to be much more predictable and the sample color is the actual finished color. However, you have to consider that you don’t know what color the original product was that was stained which of course will effect the end result.  I’m going to do some research and find out if there are any paints that could be used.

Now on to the technical part of how the sink was actually made. The carpenter carefully calculated all the angles of the sink basin and created a form made of plywood coated with formica. There were two parts to the form, an interior structure that formed the inside of the sink and an exterior structure that formed, guess what, the exterior.

Interior…

    amazing!!! i say stain the concrete so it matches the darker striations of the marble. OR if you seal the concrete, will it finish darker?

    Hey nice sink,
    I’m in the middle of a similar do it myself project and would like to ask you a question.
    How do you prevent the flat part of the mould from overflowing when you pour in the concrete in the higher part? (Was it archimedes law?)
    And how did you get the nice light color? It doesn’t look like standard concrete to me…

    Best regards,
    Benno , Netherlands.

      Hey Benno,
      The sink had an interior form and an exterior form and was made upside down, so the flat part was at the top. Having the two forms forces the concrete to go where you want it to. Be sure to agitate the concrete enough to make sure it is evenly distributed and there are as few air bubbles as possible. To achieve the light color, we used White Portland Cement instead of regular grey concrete. It’s more expensive but we wanted the white tone. White Portland Cement is sold at some Home Depot stores here in the states, I’m not sure where you would find it in the Netherlands. Good luck!
