For those who are into do-it-yourself remodeling, knowing how to build the best bathroom cabinet is a definite must for your toolbelt. By making your own bathroom cabinets, you are able to get exactly what you want to make your bathroom the ideal sanctuary for your family.

We’ve gathered together some ideas for how to upcycle some existing furniture and unique items into bathroom cabinets, as well as a short tutorial on building one yourself.

Building a Bathroom Cabinet

If you’re interested in creating your own custom bathroom cabinet, but have no idea where to start, we are here to help you out. We found a step-by-step guide to help you in building your very own custom bathroom cabinet.

The concept behind this particular vanity is recycling an old dresser. This dresser can be an old forgotten piece of furniture you have had in storage for years, or a piece you spot at a flea market or Salvation Army thrift store.

All you need to do is follow these short, simple instructions, and you will have a new vanity.

A word of caution before we start: While it’s entirely possible to use an older sink with this project, it is suggested that you purchase a brand-new sink instead. Older sinks may be more difficult to find plumbing fixtures for that work correctly.

How to Build Your Own Bathroom Cabinet

1. Gather Your Supplies

The first thing you’ll need to do is gather up your supplies. You’ll need the following items:

  • Dresser
  • Sink
  • Sheet of Formica
  • Jigsaw
  • Pencil
  • Tape Measure
  • Faucet
  • Wood Glue

2. Determine the Fit

Next, you’ll need to determine exactly how your sink and plumbing will fit into the dresser you’re using for the project. Check and see if the drawers are going to be in the way. If some of them are, you may have to remove the drawer bodies and re-attach the drawer fronts permanently to the dresser body.

3. Remove the Drawers

Once you’ve decided how to approach installing the sink into the dresser, remove the drawers for easier maneuvering during construction.

4. Prep the Formica

Now, take the sheet of Formica, and place it on top of the dresser. Make an outline of the shape of the dresser on the underside of the Formica with your pencil.

5. Cut the Formica

Take your jig saw and carefully cut the Formica according to the shape that you have just outlined in the shape of the dresser top.

6. Remove Excess and Glue

After you finish cutting the Formica, remove the cut excess. Then you will need to use some wood glue to attach the Formica to the top of the dresser.

7. Use Your Sink Template

If the sink you purchased came with a template, you now need to place the sink template on top of the dresser where the sink is going to be. Use your pencil to trace the template onto the Formica.

If you have no sink template, though, there’s a simple solution. Take your sink, turn it upside down and then position it correctly on top of the dresser. Now you will need to trace an outline of the sink onto the Formica.

8. Cut the Formica Again

Now, take your jigsaw and carefully cut out a hole in the dresser through the Formica.

9. Cut a Hole in the Back

Now, using your jigsaw once again, cut a hole in the back of the dresser. This hole is so that you will be able to accommodate and attach the plumbing properly.

10. Move the Bathroom Cabinet

You are now ready to move the new vanity to the bathroom where it will be housed. Get the new bathroom cabinet flush against the wall.

11. Place the Sink

Now, put the new sink in place on top of the bathroom cabinet.

12. Attach the Plumbing

Follow the instructions given with the plumbing pieces, and view some online tutorials to make sure you get the pipes, fixtures, et cetera into place properly.

If you’re not confident in your plumbing skills, it’s perfectly acceptable to call a professional instead, and avoid the risk of flooding or damaging your bathroom in some way.
