Steps for replacing the Kohler toilet seat with hidden bolts

First, take out the worn-out seat.

Start raising the seat and removing any bolts or other visible attachment hardware. Do this while the seat is up. Depending on the bolts being utilized, this may need either pliers or a screwdriver.

If the seat is difficult to remove or is stuck in place, you may need to use penetrating oil on the bolts to make them easier to release.

Fifth step: Tighten the bolts and make sure the seat is secure.

Make sure the seat is mounted firmly by hand-tightening the bolts and any additional mounting hardware that may be necessary. When you want to tighten the bolts, you may use a screwdriver or pliers, but you need to be cautious not to overtighten them.

If the seat is difficult to open or shut, this might be an indication that the hinges are broken or jammed. To solve this problem, lubricate the hinges using a lubricant that is based on silicone. You may need to repair the hinges if they’ve been damaged.
