I have a real fondness for little household fixes that make a room feel tidier without turning into a whole weekend project, and this toothbrush holder is exactly that kind of thing. By gluing small copper pipe fittings onto a wooden soap dish, you get a sturdy, handsome spot for toothbrushes that keeps them upright, lets them dry well, and adds a warm, polished touch to the bathroom counter.

It’s a good project for anyone who likes simple practical DIYs, especially if you want something that looks a bit more thoughtful than a plastic cup by the sink. I’m always pleased by projects like this because they remind me of the old Midwestern habit of making do beautifully—using plain materials in a neat, useful way that lasts.

Materials

1 rectangular wooden soap dish, about 5 1/2 x 3 1/2 inches
4 small copper pipe fittings, 3/4-inch diameter couplings or caps with open centers wide enough for toothbrush handles
1 tube waterproof clear construction adhesive or strong bathroom-safe epoxy, about 1.5 to 2 ounces
1 sheet fine-grit sandpaper, 220 grit
2 tablespoons rubbing alcohol
4 cotton pads or paper towel squares
1 ounce clear water-resistant sealer or polyurethane
1 small foam brush, 1 inch wide
4 toothbrushes for sizing and final use

Instructions

1. Lightly sand the top of the wooden soap dish and the bottoms of the copper fittings to help the adhesive grip better, then wipe away the dust.

2. Clean the sanded spots with rubbing alcohol on cotton pads and let everything dry completely so the glue bonds well.

3. Brush a thin coat of clear water-resistant sealer over the wooden soap dish, including the edges and slats, and let it dry fully according to the product directions.

4. Set the copper fittings on the soap dish without glue and test the spacing, arranging 4 fittings in a straight row centered along the length so toothbrush heads will not bump into each other.

5. Mark each fitting position lightly with a pencil, leaving a small gap between each one and keeping them away from the outer edge of the dish.

6. Apply a generous bead of waterproof adhesive to the bottom of the first copper fitting, press it onto its marked spot, and repeat with the remaining fittings.

7. Check from above and from the side that all 4 fittings are lined up evenly, then adjust them right away before the adhesive starts to set.

8. Let the piece cure undisturbed for the full time recommended on the adhesive package so it becomes strong enough for daily bathroom use.

9. Test each opening with a toothbrush handle and make sure the brushes stand upright easily; if needed, remove any small squeeze-out of glue with a craft stick or fingernail once it is rubbery.

10. Place the finished holder by the sink and slide a toothbrush into each copper fitting, with the soap dish underneath catching drips and helping the whole piece stay neat and dry.

Variations & Tips

For two people: Use 2 or 3 copper fittings instead of 4 if you have a smaller sink area, but keep them centered on the soap dish so the holder still looks balanced.

For a richer finish: Add a second coat of clear sealer to the wood, especially on the ends and underside, to help it stand up to splashes over time.

For easier cleaning: Choose a soap dish with open slats rather than a solid tray, since airflow helps toothbrushes and the base dry faster.

Copper care: If you like bright shiny copper, polish the fittings before gluing them on; if you prefer an aged farmhouse look, let them darken naturally.

Adhesive tip: A waterproof epoxy usually gives the strongest bond, but any bathroom-safe adhesive meant for wood and metal can work if you allow full cure time.

Counter protection: If your soap dish doesn’t already have feet, add 4 small clear rubber bumpers underneath so the holder won’t slide and water won’t sit beneath it.
