DIY Toilet Seat Replacement

Pro or not, installing a new toilet seat is an easy work to do. All you need to do is set the seat in place and pull tight the nuts. But what’s tedious is the process of removing the old seat. Most of the time, it’s hard to unscrew the nuts because the bolts that fasten the seat are so corroded. To give you a better solution, here’s a tip:

Check out the bolts that are fixed on the seat. Lucky you if the bolts or nuts are plastic as they can’t corrode and will easily come off. To expose the bolt’s head, pry open the cover behind the seat. While you hold the nut underneath with the pliers unscrew the bolt with pliers or a screwdriver.

Use your drill, drill bit collection, and safety glasses if lubricant won’t free the nut. Drill into the bolt where it meets the nut using a 1/16-in. bit. About 1/4 in. should be drilled into the bolt. Next step, expand the hole using a 1/8-in. Bit, then by a 3/16-in. bit. After which, attempt for the socket wrench again. To break off the bolt as you turn the nut is your goal now and not to unscrew the nut. Keep expanding the hole if the bolt won’t break. To break it eventually, you’ll exhaust the bolt enough.

You may be able to unscrew the nuts with pliers if the bolts are metal. The best device for this piece of work is a socket wrench equipped with a deep-well socket. It requires a 1/2-in. socket for most toilet seats. It fits over the long bolt and grips the nut tightly for the deep socket. All you have to do is turn the nut counterclockwise as most metal bolts aren’t covered by a flip-open cover. Just twist as hard as you can. You might break it off if the bolt is brass or badly corroded steel, which is okay.

Saturate it with a penetrating spray lubricant like WD-40 if the nut won’t dislodge. To catch the over-spray, hold a rag behind the nut. To penetrate, give the lubricant 15 minutes, then do it again.
