If you ever had old limescale and rust like below in the base of your shower and wanted to clean it up without spending a whole day scrubbing it by hand than the powerdrill scrubber head is a tool you should build.

Estimated time: 20 minutes

Step 1: Shopping List and Tools

You will need the following tools:

  • a cordless powerdrill + a drill bit
  • a handsaw

Optional, but nice to have:

  • coarse sanding paper (P40 for example)

Step 2: Drilling

First drill a hole in the center of your brush. The positioning of the hole doesn't need to be perfect, a bit of wobble when the brush will rotate isn't that big of a deal.

The diameter of the hole should be wide enough so that you can easily put the screw through but not too big so that the head of the screw doesn't fall through, obviously.

Step 3: Mounting the Screw

Mount the screw through the hole you just drilled.

Step 4: Securing the Nuts

Secure the screw on the top side of the brush with both nuts. This is critical because it will prevent the nuts from moving as the brush rotates.

If you want to do this properly it makes sense to read:

this page where the two nut locking method is explained in significant detail.

Step 5: Get Rid of the Handle

Cut away the handle with a handsaw. You could do it in the beginning but I found that it's easier to handle the brush without removing it. The thing to take care at this point is to leave as little of the handle sticking out as possible.

You can finish up the resulting edge with a bit of sandpaper but that's optional.

Step 6: Enjoy

Enjoy your diy powerscrubber.

Note: As you can see I didn't get rid of most of the parts sticking out of the round brush which made using a bit annoying as it hits stuff when rotating. Do not make the same mistake.

Step 7: Effects

Powerdrill scrubbing is pretty effective. Here you can see that after about 1 minute of scrubbing on high-speed drill setting most of the limescale and rust is removed.

The worse thing is that the fungus is not affected, so that will need to be taken care of separately.

Step 8:

Amazing this helped crush cleaning my tub and all the corners in my bathroom. Thank you for posting it's a huge time saver!
<p>Great idea. May try this on my shower.</p>
<p>Good instructable. Any chance of adding a video showing it in action?</p>
<p>This is really clever.....!</p>
<p>Nice- I tried to do this once, but used scrubbing pads. Your systems better since the nylon bristles won't scratch anything.</p>
