I would like to install on a one piece Kohler toilet a bidet. When I tried to unscrew the screw from the seat, it just didn't move, not with the screwdriver nor the drill. So I put wd40 but still doesn't move. Can u please help me.
We have 3 Kohler 1-piece Rialto toilets. I replaced the seats on all 3 of them. The first two took about 2 minutes each. Unscrew bolt, replace seat, re-screw bolt. But the 3rd toilet had bolts that would not budge. I bought an impact screwdriver from Amazon and went to work. Using a small sledge hammer the first bolt finally loosened after about 30 blows. What a workout! The second bolt was more stubborn and the groove (flathead) at the top was beginning to widen causing the flathead bit to slip. I used layers of heavy gauze and plastic waterproof tape to narrow the groove and finally got the thing to unscrew. What a pain!
