What you need
A new toilet seat with fittings (available from most good hardware shops)
Pliers
Nothing breaks the concentration like an annoying busted toilet seat... So fix it! It's easy and and quick and worth it.
Step 1
Now remember this is for regular toilet seats, not your space-age fruity designs which may have special fixtures... The seat is attached by 2 metal bolts that hold the seat hindge to the bowl. At the back under the seat will be 2 wing nuts, or just plain nuts. Use a spanner or the pliers to undo the nuts if they are tight, turn them anti-clockwise to undo. Once the nuts are off you can simply lift the old seat upwards and the bolts will slip out, nice.
Step 2
Now you need to get the new seat, and put the 2 bolts attached to the seat back through the holes in the bowl. Remember to add any washers that may be provided with the seat. Now add another washer to the end of the bolts on the underside of the bowl, and do up the nuts a little. Now adjust the seat so it is positioned perfectly for optimal comfort, and tighten up the nuts! Bingo, a comfy crapper.
