  2. In case your TOTO toilet seat is still under warranty, review the warranty terms or contact customer support to ensure you won’t face any issues before you remove the toilet seat.

Step 1: Prepare

To remove your TOTO toilet seat, make sure you get the right tool. Here’s what you’ll need:

  1. Screwdriver
  2. Pliers
  3. Toilet cleaner and disinfectant
  4. Gloves
  5. A sponge

Make sure to put on your pair of rubber gloves before proceeding with any of the steps below.

Step 2: Identify your toilet seat model


Identify the specific model or type of your TOTO toilet seat. Different models may have varying mechanisms for removal and installation. 

Determine if your TOTO toilet seat is top-mounted or bottom-mounted.

  1. Top-mounted seats have visible bolts on the top.
  2. Bottom-mounted seats may come with hidden bolts beneath the hinge covers.

If you plan to remove a TOTO washlet, a type of heated seat with an automated bidet, the bolts may be hidden by the washlet.

Once you’re all set, get ahead to the next step.

Step 3: Open bolt covers


Step 4: Unscrew the bolts


You need to identify plastic bolts and nuts on the toilet. If the bolts are rusted or corroded, spraying penetrating oil is a good idea.

  1. Begin unscrewing the bolts using a screwdriver. Turn the screwdriver in a counter-clockwise direction to unscrew the bolts. Apply steady, firm pressure but avoid excessive force that could strip the threads or damage the bolts.
  2. While unscrewing the bolts from the upper side, you may need to hold the nuts underneath the toilet seat to prevent them from spinning. This step can be done by holding the nuts with your fingers or using a pair of pliers.

Make sure to remove both the nuts and bolts completely.

Once you successfully take off the TOTO toilet seat, you can proceed with cleaning the toilet.

Here are a few things you can follow:
