If you’re planning to install a toilet door frame in Singapore, it’s important to do it correctly from the beginning. Many homeowners face problems with their toilet door frames because of Singapore’s high humidity. The wooden parts start to swell, the metal parts begin to rust, and the door stops closing properly. I’ve seen this happen in both older HDB flats and newer BTO units.
This isn’t just another general DIY guide. In Singapore, our HDB and condo bathrooms are built with specific measurements and materials. Our climate is humid, and toilet areas are often wet. That means a toilet door frame installation here comes with its own set of challenges, but don’t worry. I’ll show you exactly how to handle them.

Why Installing a Toilet Door Frame Is Necessary in Singapore
Toilet doors in Singapore are used many times a day. Over time, the frame becomes loose, corroded, or swollen due to constant moisture. Especially in older HDB flats, the original wooden door frames often absorb water and start to rot. A damaged frame causes the door to jam or shift out of place. Replacing the frame early helps avoid water leaks, prevents mold, and keeps your bathroom neat and safe.
Tools and Materials You Will Need
Here’s a detailed list of what you’ll need. You can get most of these tools from local shops like Selffix DIY or Horme Hardware.
Tools:
- Pry bar or flat-head screwdriver (for removing the old frame)
- Measuring tape
- Drill with masonry and wood bits
- Spirit level
- Hammer
- Hand saw, or power saw
- Silicone gun
Materials:
- Prefabricated aluminum or PVC toilet door frame (available at shops like Hoe Kee or Sim Siang Choon)
- Screws and plastic wall plugs (usually included with new frame sets)
- Silicone sealant (anti-mold type is best)
- Cleaning cloth and sponge
Avoid wood or laminate frames, as these do not last long in wet HDB toilets. Go for PVC or aluminum. They are water-resistant and easy to clean.

Step-by-Step: How to Install a Toilet Door Frame in Singapore
Step 1: Remove the Old Frame
Start by taking the door off its hinges. Most toilet doors in Singapore are bi-fold or swing doors. Use a screwdriver to remove the hinges.
Next, remove the frame. In older flats, the frame might be nailed or screwed directly into the concrete wall. Gently leverage it open with a pry bar. If the cement is covering the area, chip it away carefully so you do not damage the tiles.
Step 2: Clean and Check the Wall Opening
After taking off the frame, make sure there is no damage. On the walls or ceiling, look for signs of black mold or damaged plaster. Use a damp cloth to wipe every surface. Let everything dry completely before you install the new frame. This is important as sealing a damp wall can trap moisture and cause future problems.
Step 3: Measure and Prepare the New Frame
Measure the dimensions of the door opening. Most HDB units use standard door sizes but don’t assume. Measure from top to bottom and side to side.
Cut the new frame to size using a handsaw or power saw. Many suppliers in Singapore will pre-cut the frame for you based on your measurements, so you can ask for this if you don’t have tools at home.
Step 4: Dry Fit the Frame
Place the new frame into the opening without any screws. Use a spirit level to make sure it’s straight. This step is important because uneven frames will cause the door to jam or swing by itself.
If the wall is uneven, you can use small plastic wedges (called shims) to help align the frame. You can find these at most hardware shops in Singapore.
Step 5: Drill and Secure the Frame
Once the frame is in place, mark the points where you’ll drill. Drill holes into the wall through the frame and insert plastic wall plugs. Then screw the frame into place. Start from the top and work your way down.
Use a spirit level after each screw to make sure everything stays straight. Don’t overtighten, or the frame might warp.

Step 6: Seal the Frame
Run silicone sealant around each edge of the frame where it touches the wall. Use an anti-mold, waterproof sealant. This is a must in Singapore toilets. Smooth it out using your finger or a plastic tool.
Once the sealant is applied, allow it to cure for a few hours before attaching the door.
Step 7: Hang the Door
At this step, you are ready to put up your toilet door. Regardless of having a bi-fold or swing door, you want to make sure both hinges are tight and the door moves smoothly.
Test the door several times. Make sure it doesn’t scrape the floor and closes completely. If needed, adjust the hinges slightly.
What’s Different About Installing a Toilet Door Frame in Singapore?
- Most HDB bathrooms are wet areas. This means the door frame must be water-resistant. PVC or aluminum works best.
- Older flats have cement-sealed frames. Removing them takes more effort, and you’ll often find uneven walls behind them.
- Singapore bathroom doors are usually narrower than standard doors in other countries. Don’t rely on YouTube tutorials from overseas, and measure your space properly.
- Space is limited in many homes. If you’re working in a small toilet, it may be harder to move around. Keep your tools close and clear the area before you start.
Final Thoughts:
Taking the time to install a toilet door frame properly is worth the effort. You avoid costly repairs, keep your bathroom looking neat, and stop moisture from damaging the walls. Singapore homes face high humidity every day, so materials and sealing matter.
If you follow each step carefully, from removing the old frame to sealing the new one, your toilet door will last for many years. Whether you’re doing it for the first time or replacing an old one, now you know how to install a toilet door frame the right way.
