How to Install a Bathroom Vanity: A Complete Guide from High QLO

Bathroom vanities vary in design, from freestanding to floating; some have the countertop attached to the cabinet while others are completely separate. Despite their popularity, there are few guidelines directed at securely installing vanities with separate countertops. If you are planning to get a new vanity, this guide will show you how to use brackets for a secure and stylish installation.

How to Choose the Right Bathroom Vanity

If you are considering a bathroom renovation, you need to select a suitable vanity. It’s essential to consider material, size, and style. A well-chosen vanity not only enhances the bathroom’s aesthetics but also provides practical storage and usability.

Material and Durability

Different materials have a large influence on the vanity's longevity and its maintenance. Solid wood is sturdy and provides a premium look. MDF and plywood offer cost-effective alternatives worth considering for decent longevity. Some of the most low-maintenance materials that can withstand moisture are ceramic and slate, which can even be incorporated into countertops. If thinking of durability, purchasing a high-quality material guarantees that the vanity will last for many years. 

Size and Fit

Accurate measurements are important before acquiring any vanity. Most standard sizes have widths ranging from 24 inches to 72 inches; the choice thereof depends on the existing layout of the bathroom. Wall-mounted vanities make the most of an open modern look, lending a larger space to smaller bathrooms. Free-standing vanities provide additional storage and could also be less tedious to install. Be sure to leave enough space on your design for drawers and doors so that they can open easily. 

Style and Functionality

The vanity should echo the overall design of the bath. Minimalist designs possess the most modern appeal, while classic wooden finishes bring warmth and a traditional flavor. Storage is yet another important consideration—drawers, closets, and shelves can help keep your bathroom essentials organized. For those who prefer the slick look, handle-free designs with "push-to-open" mechanisms give them a clean aesthetic appeal.
