Are wall-mounted or countertop toothbrush holders better?

It depends on your sink space and whether you want to drill. Verified-purchase reviewers favor wall-mounted and adhesive holders for freeing up counter space and improving drainage, while countertop cups (ceramic or diatomite) are praised for being move-anywhere simple with no installation. If you rent or want zero damage, suction-cup and self-adhesive designs are the most-mentioned compromise.
