Hello, I'm the JACO editor. I completely understand that most Hong Kong residents weren't present when their toilet was installed, so they have no idea how the seat cover was attached. When the seat breaks, they don't know how to replace it. Today, I'll teach you how to replace and install a toilet seat cover.
First, Measure the Hole Distance on Your Toilet
Before purchasing a replacement seat, you need to measure the distance between the two mounting holes on your toilet bowl. This measurement is critical for ensuring compatibility. Most standard toilets have a hole distance of around 15-18cm, but it varies by brand and model. Take a photo of your toilet and note the measurements before shopping.
