With smart planning and the right tools, even a narrow bathroom cabinet or a bathroom cabinet small can be installed quickly and securely.
Before you begin, gather the essential tools and materials based on the type of cabinet you are installing. This ensures a smoother workflow and minimizes the risk of mistakes.
| Tool/Material | Purpose |
|---|---|
| Stud finder | Locate wall studs for secure mounting |
| Power drill | Create holes for screws and anchors |
| Level | Ensure the cabinet is straight |
| Measuring tape | Accurate placement and alignment |
| Pencil | Marking drill points and measurements |
| Screws and wall anchors | Securing cabinet to wall |
| Silicone caulk | Seal gaps between cabinet and wall |
| Wood shims | Level the base or adjust height |
| Screwdriver | Tighten hardware and hinges |
If you’re installing a cabinet with silent hinge or a lightweight door cabinet, ensure you have the manufacturer’s hardware kit on hand.
Let’s get straight into the step-by-step process. Whether you're mounting a bathroom cabinet with mirror or placing a bathroom cabinets with sink unit, the steps below will guide you through.
Use a measuring tape to record the width, height, and depth of the installation area. Confirm that your new cabinet—whether it's a 36 inch bathroom cabinet, a compact unit, or a narrow bathroom cabinet—will fit comfortably without obstructing doors or plumbing.
Pro tip: Leave at least 18 inches above the cabinet if you’re installing a bathroom cabinet over the toilet to allow for easy access.
Use a stud finder to identify the wooden studs behind your bathroom cabinet wall. Cabinets must be anchored into studs for stability, especially heavier models like an aluminum bathroom mirror cabinet.
Hold the cabinet against the wall at the desired height and use a pencil to mark the top edge and screw hole locations. Use a level to ensure the markings are straight.
Drill pilot holes where the cabinet will be anchored. If you're installing a recessed bathroom cabinet, carefully cut out the drywall to the size of the cabinet box.
Hold the cabinet in place (use a helper or temporary support) and drive screws into the pre-drilled holes. For wall-mounted units like a cabinet with double mirror, secure at least two screws into wall studs and use wall anchors as needed for additional support.
If your cabinet comes with doors and hardware, install them after the unit is securely mounted. For models with silent hinge, follow the manufacturer’s instructions to ensure smooth, soft-close functionality.
Apply silicone caulk around the edges where the cabinet meets the wall to prevent moisture from seeping in. Wipe off any excess and allow it to cure for at least 24 hours.
With so many styles on the market, choosing the right cabinet can make or break your installation experience. Here’s a comparison of common types and their installation difficulty:
| Cabinet Type | Installation Level | Best For |
|---|---|---|
| Wall-mounted | Moderate | Small bathrooms, modern designs |
| Floor-standing | Easy | Larger bathrooms with floor space |
| Recessed | Advanced | Sleek, flush-wall designs |
| Over-the-toilet | Moderate | Vertical storage in tight spaces |
| Aluminum cabinets | Moderate | Long-lasting, moisture-resistant installs |
Fiesono offers a wide selection of ready-to-install cabinets that suit various bathroom layouts, including multifunction mirror door cabinets, recessed bathroom cabinets, and lightweight door cabinets.
A bathroom cabinet over the toilet is perfect for maximizing unused vertical space. Be sure to:
Leave at least 18 inches of clearance above the toilet tank
Use wall anchors if no studs are behind your drill points
Choose shallow-depth cabinets to avoid head bumps
Narrow bathroom cabinets are ideal for tight floor plans. Installation tips include:
Leveling the base with shims
Reinforcing floor-standing units with screws into the floor or wall
Using corner placement to maximize storage
For mirrored cabinets:
Use heavy-duty wall anchors or toggle bolts
Confirm level placement to avoid distorted reflections
Match mirror height to average eye level (typically 60 inches from the floor)
Installing a recessed bathroom cabinet involves cutting into your wall cavity. Consult a professional if you're unsure about electrical or plumbing placements behind the wall.
Modern bathrooms aren’t just about aesthetics—they demand functionality. Storage bathroom cabinet units provide essential room for toiletries, towels, and daily essentials. Ideal placements include:
Under the sink (vanity style)

A1: Yes, many bathroom cabinets are designed for DIY installation. Wall-mounted and floor-standing models are easier to install, while recessed models may require professional assistance.
A2: Use a stud finder to locate wooden studs behind the drywall. Mounting directly into studs provides the most secure hold, especially for heavier cabinets like an aluminum bathroom mirror cabinet.
A3: Vanity cabinets are typically 32–36 inches tall. Wall-mounted cabinets should be installed so that the bottom edge is about 60 inches from the floor for comfortable access.
A4: Absolutely. Bathroom cabinet over the toilet designs are great for small bathrooms. Just ensure there’s enough clearance (at least 18 inches) above the toilet tank.
A5: Measure the cabinet box, cut an opening in the drywall, and frame the cavity with wood supports. Then, slide the cabinet in and secure it with screws. Always check for electrical/plumbing behind the wall first.
A6: Aluminum cabinets are more resistant to moisture, rust, and warping, making them ideal for bathrooms. They’re also eco-friendly and lightweight, which simplifies installation.
A7: Floor-standing cabinets are the easiest, as they don’t require wall mounting. Lightweight door cabinets are also simple to install due to their reduced weight and user-friendly hardware.

With the right tools, a little planning, and the right product—like those from Fiesono—you can complete your upgrade in just a few hours.
