How to remove an Ideal Standard toilet seat which doesn't have hex socket bolts

[oceanclub]

We have two bathrooms with Ideal Standard toilet seats. One you can remove the seat by simply undoing hexagon socket bolts with a small hex key. The other seat has no visible bolts and I've no ideal how to remove it. Even Ideal Standard couldn't help. They said simply to pull the seat upwards but even a strong tugging on it doesn't work. I've attached a video and hopefully someone can help. On the underneath of the toilet I can feel two holes either side with a rod coming through it from what I presume is the seat. But not nut I can feel to loosen it.

Ideal Standard Toilet - replacing the seat is impossible!!

Unbelievable - they seem to have put the nut about an arms length up inside the ceramic! See photo. Not only that, but I'm jiggered if I can find out how to remove the old seat. Normally, you just unscrew the two screws, life off the seat, and install the new one. But this Ideal Standard...

Thanks: I looked at this and it mentions "Lift the chrome disc." However my seat is different it seems - the disk on mine isn't a cover, but clamped firmly to the toilet bowl. I've even tried using a screwdriver to prise it up, in case, but no movement.

Do you push anything in on the side of the hinged part? Also underneath appears to have a screw?

I've tried pulling the lid directly upwards, trying to slide the hinges in all directions, put oil on them.

The focal point of the image underneath shows inside the toilet. So if there are screws in there, I've no idea how to access them. You'd need some specialist tool, I imagine?

Can you take a photo rather than a video so that we can zoom in?

Sure: here are some photos of both hinges from the top and from the back. And also of the underside of the bowl, showing the two holes mentioned with a hexagonal rod slightly emerging, but no nut accessible.

I hope it isn't the type in your second video. I once spent an hour rolling a toilet pan around the floor waiting for the "slip thingy to fall out. Chiffin' stoopid design. You cannot take the seat off without the lower part of the fitting falling off into the cavity.

I can't be sure, looking at the photos, it looks like you may need a box spanner. I have never encountered those before.

Thanks all. No idea why they use this type of seat, removing it seems unreasonably difficult. Will try get box spanners and see how I get on.
