How to Make a Wood Toilet Tank Topper Box

    I may earn a small commission for my endorsement, recommendation, testimonial, and/or link to any products or services from this website at no cost to you.

    While adding a bathroom shelf to an upper alcove, I had some spare wood lying around and decided to build a toilet tank topper since I was giving my bathroom an update.

    A toilet topper box or basket can be used to store extra toilet paper, books, or other bathroom accessories in an easy-to-find spot for guests – and is a great way to add some personality to an otherwise boring part of the bathroom.

    In this post I’ll walk through what materials you need and how to build a toilet tank topper for your own bathroom!

    Materials for Building a Toilet Tank Topper Box:

    • Wood
    • Ruler or Tape Measure
    • Tablesaw or Chopsaw
    • Wood Glue
    • Nails
    • Hammer
    • Clamps
    • Stain
    • Brush & Rags for Stain

    How to Make a Toilet Tank Topper Box:

    • Measure your toilet tank lid to create a custom topper made to fit your toilet
    • Mark your wood where you’ll be making cuts for your tank topper
    • Cut the wood into 5 pieces – 1 for the bottom, 1 for the back, 1 for the front, and 2 for the sides

    • Sand the edges lightly to smooth
    • Assemble your tank topper by brushing wood glue onto the edges, then applying clamps to hold in place while drying
    • Hammer nails into the corners for additional strength

    • Once dried, sand the faces of the tank topper so the wood is smooth – you can also sand the corners to give a worn or rustic look
    • Leave your topper unfinished, add stain, paint, and/or polyurethane/polycrylic

    I used Minwax’s Special Walnut stain and a matte (non-shiny) polycrylic that matched some shelves I was adding into the bathroom.

    • Place your tank topper on your toilet and to keep toilet paper in an easy-to-reach spot for guests
    • You can also style your tank topper with books, candles, or other bathroom accessories!
