Wobbling toilet currently fixed with scerws into concrete!

Hi,

I have a downstairs toilet which wobbles about when someone is sat on it.

After having a look at how the base is held down, I noticed that it seems have four screws and not bolts! I put a Phillips screwdriver into a couple of them and the screw just spins around.

So I am a bit unsure what fixings I should use to secure the toilet to the concrete floor. Should the people who installed the toilet have used bolts instead of screws?

If so, how should I go about removing and reinstalling the toilet as I have not done this before and don’t want to end up with water all over the place

Also, if I need to use bolts, how do I know which ones to get?

Any help would be appreciated.

FYI.
The toilet discharges the waste out of the rear of the toilet and has a water feed pipe that is quite long from the cistern back to the toilet.

Please see the photo's below which should explain further.

Screwfix 43370 is basically some long corrosion resistant screws, plugs and caps - ideal for your job.
It depends on how much damage there is to the base beneath the tiles whether anything will hold though.
If you are dextrous with your masonry drill, its possible to drill through the pan holes and push the plug through, but if you aren't happy about that, the loo at least can be pulled out of its soil pipe by sliding forwards - which is a better arrangement than some!

Corrosion resistant screws are what are normally used, bolts are not used for fixing down pans, it appears from the photos that your screws are corroded this is what may have led to the pan becoming loose and wobbling, or the plugs in the ground are not gripping sufficiently

How to fix your loose toilet:

1. Close lid of toilet and place a large bag of sand on top to hold toilet down.

2. Remove 1 brass screw that is holding down the toilet.

3. Supply and apply a small tin of foam filler into the screw hole, don't use to much.

4. Remove foam filler nozzle and place tape over the screw hole.

5. Leave toilet for 12hrs then remove sand and use toilet as normal. (remove tape and push the brass screw back into the hole)

Thankyou all for your help

I will pop down to screwfix this weekend and see if I can
finally sort out my toilet.

Cheers.

Just a quick update.

I got the required screw kit from ScerwFix and fitted them to the toilet on Saturday.

Now have a rock solid toilet base

The only problem I encountered was that the orignial screws had rusted right through, so I had to the holes out with the rest of the old screw in situ.
Which was a bit trickey as the drill bit kept slipping away from the hole. But got there in the end.

Thanks again for the pointers.
