Bathroom wooden cabinets take more abuse than you’d ever realize. Daily steam from hot showers, splashes from sinks, and constant humidity slowly wear down the finish. Over time, the wood can look dull, faded, or worn out, even though the cabinet itself is still strong. 

Restaining is a great way to give your cabinets a facelift and protect them from moisture damage. It costs far less than replacement and lets you keep the natural beauty of wood, unlike painting. 

In this article, I’ll walk you through how to restain bathroom cabinets step by step. It’s a simple weekend task. 

How to Select the Right Bathroom Stain?

Restaining works on solid wood or wood veneer cabinets. Water-based stains are the best choice for bathrooms because they dry quickly, have lower fumes, and resist mildew better. 

As for the stain color, go with something that complements your tile, countertops, and fixtures. Here are some popular options: 

• Medium-toned wood
• Dark walnut tones
• Warm brown tones
• Light stain products 

Pro tip: Make sure to always test the color on the inside of a door or drawer first. Bathroom lighting can significantly change how the stain looks. 

Tools and Materials Needed

Here are all the tools and materials you need for restaining your bathroom cabinets:

• Screwdriver
• Drop cloth
• Mild wood cleaner or soap 
• Coarse sandpaper (80 to 100 grit)
• Fine sandpaper (180 to 220 grit)
• Wood conditioner
• Wood stain
• Paintbrush 
• Microfiber cloth 
• Sealant or polyurethane 

Safety gear:

• Gloves 
• Protective goggles 
• Respirator  

Make sure to keep the windows open and turn on the exhaust fan for ventilation.

Steps to Restain Bathroom Cabinets

Restaining bathroom cabinets requires some effort and patience, but it’s definitely a manageable DIY task if you follow these steps carefully: 

Step 1: Empty and Protect the Area

Staining can be messy, so start by preparing the space:

• Remove all items from cabinets and drawers
• Take out shelves, if possible
• Cover floors, countertops, and fixtures with a drop cloth
• Use painter’s tape on walls

Step 2: Remove Cabinet Hardware

Remove all cabinet doors, drawers, and handles. Try to remove the drawer front from the drawer, but if doing so could damage it, stain it with the front in place. 

Here are some tips to make staining your bathroom cabinets easier:

• Label doors so you remember where they go
• Keep screws in small labeled bags
• Lay doors flat on a clean surface

Step 3: Clean Cabinets Thoroughly

Bathroom cabinets tend to accumulate soap, grease, and moisture film. Stain won’t soak into dirty cabinets, so make sure to clean them first. 

• Use a mild wood cleaner
• Wipe down every surface, especially around handles and sink areas
• Let the wood dry completely

Step 4: Sand Off the Old Finish

Sanding removes the old finish and opens up the wood grain.

• Start with coarse sandpaper (80 to 100 grit) and sand along the grain, not against it, to avoid scratches
• Repeat the same with fine sandpaper (180 to 220 grit)
• Wipe off any dust with a clean cloth 

Step 5: Apply Wood Conditioner

Using a wood conditioner is especially important for bathroom cabinets because it helps the stain absorb evenly, reduces blotching, and prevents overly dark spots. Here’s how to apply it:

• Use a paintbrush to apply the conditioner 
• Let it soak in as per the manufacturer’s instructions
• Wipe off any excess moisture with a clean microfiber cloth

Step 6: Apply the Stain 

Now it’s time to stain the cabinets:

• Stir the stain thoroughly, don’t shake it. Make sure to pull the solids from the bottom of the can and mix them in.
• Use a high-quality paintbrush to apply the stain. Low-quality brushes can leave bristle marks. 
• Work along the direction of the wood to prevent scratches
• Wipe off any excess with a clean cloth 

Step 7: Let the Stain Dry and Apply a Second Coat

Let the first coat of stain dry for seven to eight hours. Check the drying time specified on the container and follow it accordingly. Don’t touch the surface, and keep the area as dust-free as possible with good airflow while it dries.

After the first coat dries, follow the same steps to apply a second coat. It gives a richer finish and better protection against moisture. 

Step 8: Seal to Protect From Moisture

Sealing is key to protecting bathroom cabinets from moisture. 

• Use a clear polyurethane or water-resistant sealer
• Apply two to three layers of thin, even coats
• Let each coat fully dry before applying the second coat
• Sand lightly between coats

Step 9: Reinstall Doors and Hardware

After the top coat dries: 

• Reattach hinges and handles
• Hang doors carefully
• Put the shelves back 

Avoid slamming doors for the first few days.

Common Mistakes to Avoid

Here are some common mistakes that can affect the appearance of your bathroom cabinets: 

• Skipping sanding
• Restaining during humid weather 
• Applying too much stain 
• Rushing drying time
• Skipping the seal coat
