How do you tighten a toilet seat with no access to the underside?

[ScottieA]

Hi we have a toilet unlike any I have seen before. The seat has become loose, with normal toilets I know you just tighten it with the bolts underneath the seat. This one however the toilet / ceramic is sealed with no access to the underside. I have looked at the seat itself and it has no plastic caps to flick off in order to access a screw. I am currently out of ideas. If anybody could shed some light on this I would be very grateful.

Some seats fix from above into a plastic insert in the WC pan. You may find that there are covers on the seat fixing that need to be removed before you can see the fixing bolts. These covers may fit over the whole seat fixing so they're not obvious.

buddy some new seats are fixed thru the hindge of the seat, just pop it off and tighten with a 4mm alan key

some seats have those chrome covers that slide up and round so you can get to the screws underneath might be worth having a look at that, then again i was fitting a hertiage pan and when it was fitted you needed miget hands to get your hand round the back to tighten the seat so god knows how your meant to tighten that up if it comes loose

I hope this helps

Try a toilet seat installation tool from Screwfix

Just today i came across your problem, and i had no other option but to take the wall mounted pan off the wall to tighten the the nuts of the seat which were on the underside of the pan, job done happy customer

Also had this problem think it was a Roca toilet the back of the pan was flush to the wall so the nuts to the seat were concealed . As said in a previous post only option was to take pan out,tighten the nuts, fit the the pan back in place. jobs a good un.

There is a special 'blind hole' fixing screw that you can insert from above and tighten without needing access to underneath. Use a pair of these!

They are obtainable from BES, called 'Wellnuts', cat #17054.

Brilliant advice,Hugh. Worked perfectly with a 3mm alan key.

Certainly not necessary to take the whole toilet off the wall as some other experts have suggested.

Did a Imex pan the other week, had hidden buttons on the hinges to remove the seat and lid and underneath was the screw.

tried above with an allen key and worked well after 1 year of a loose seat. used a mirror to check where the hole was at the back of the hinge. toilet type to the floor

It's so nice when people come back and update. Well done

I had exactly the same problem of not being able to work out how to tighten the logo seat. It's quite an expensive loo and soft close mechanism. The entire seat can be lifted off by pressing release buttons on the inside of the two hinges. Then you see a stainless steel plate with the lugs on that the seat slots onto. (some have a single s/s plate others have two round s/s caps. You need to gently prise (flat screwdriver - carefully) the stainless steel plate (or caps) off. Then screw tops are revealed each side of the pan which you tighten up (first positioning correctly for the seat). Then replace the stainless steel plate (or cap) and slot the seat assembly onto the lugs. All done in less than 5 minutes. It's magic!

Thanks for that. Would've been more impressed if you were registered.
