What to Know Before Installing Bathroom Cabinets: A Prep Checklist

Bathroom renovations can completely transform your home—especially when it comes to upgrading your cabinets. Whether you’re refreshing a powder room or redesigning a master bath, new cabinets are one of the best ways to add function, style, and value. But before you dive into installation, a little preparation can go a long way.

Here’s your complete checklist for getting ready to install bathroom cabinets—brought to you by the cabinet experts at Six Points Cabinets in Phoenix, Arizona.

1. Measure Your Space Accurately

Start with the basics: Accurate measurements. This is one of the most critical steps before ordering or installing cabinets.

  • Measure the width, height, and depth of your space.
  • Note the location of plumbing lines, electrical outlets, mirrors, and light fixtures.
  • Consider door swings, drawers, and any other moving parts that could affect functionality.

Even a small measuring error can create major installation headaches. If you’re unsure, a professional installer can verify your dimensions before you buy.

2. Choose the Right Cabinet Type

Bathroom cabinets come in a variety of styles, but prefab cabinets (like those offered at Six Points Cabinets) provide the perfect balance of affordability, quality, and convenience.

  • Prefab cabinets are pre-built and ready for installation—saving you both time and money.
  • Semi-custom options allow you to choose finishes, hardware, and configurations.

Prefab cabinets are a great option for most Phoenix homeowners looking for a quick, stylish upgrade without the long lead times of custom designs.

3. Select Durable, Moisture-Resistant Materials

Bathrooms experience constant humidity, temperature changes, and water exposure. Choose cabinets made from materials built to handle moisture, such as:

  • Plywood or MDF with a high-quality laminate finish
  • Thermofoil cabinets for easy cleaning and water resistance
  • Solid wood fronts sealed for durability

Avoid untreated wood or low-quality finishes that can warp or swell in Arizona’s fluctuating temperatures and humidity levels.

4. Plan Your Plumbing and Electrical Layout

Before installation, double-check your plumbing and electrical connections. You’ll need to ensure your cabinet and sink base align with your water lines and drains.

If you’re relocating plumbing or electrical fixtures, plan this early—ideally before your cabinets are delivered. This helps avoid last-minute changes or costly rework once installation begins.

5. Prepare the Installation Area

Once your old cabinets are removed:

  • Inspect walls and floors for any damage or unevenness.
  • Clean and dry all surfaces to ensure proper adhesion and fit.
  • Mark reference lines for cabinet height and alignment.

Taking the time to prep your space ensures a smoother installation and a more professional finish.

6. Choose Hardware That Complements Your Style

Don’t overlook the details! Handles, knobs, and pulls are the finishing touches that bring your bathroom design together.

Whether you prefer sleek modern chrome, warm bronze, or minimalist matte black, your hardware can tie your whole bathroom aesthetic together.

7. Hire a Professional Installer (or Prepare for DIY)

Prefab cabinets are designed for straightforward installation, but precision still matters. If you’re experienced with tools and want to tackle a DIY project, make sure you have:

  • A level and drill
  • Stud finder
  • Measuring tape
  • Caulk, sealant, and shims

For best results, consider hiring a professional installer—especially if you’re replacing plumbing fixtures or adjusting the layout.

8. Schedule Your Delivery and Installation

Finally, coordinate your delivery and installation timeline. Prefab cabinets from Six Points Cabinets can often be installed quickly, but scheduling ahead ensures everything arrives when your space is ready.

Keep in mind: bathroom renovations can temporarily limit access to your sink or vanity, so plan accordingly.
