Help! Any ideas how to level this corner basin?

[richardbell81]

Hello, I’ve fitted loads of wall hung basins in my time but this one is defeating me.

Whatever I do the front of the basin is much lower than the back and I can’t get it level. It’s and Ideal Standard basin with a vanity unity that goes underneath so it needs to be level. I’ve tried corner brackets, rag bolts, shimming the brackets and wall but unless I hold the front up by hand then it sinks at the front and won’t stay level so I can’t even silicone it in place.

Any ideas or suggestions would be greatly appreciated as I’m slowly loosing it!

is it meant to be level or is that correct way
so water runs back into basin and so it doesn't collect on the top at the back

I see what you’re saying and yes there should be slight fall but when does a fall just become not level? I don’t know anymore 🤷‍♂️

If it was raised a few mil off the grout line, would you be able to tell? (I mean someone other than you, you'll always know!)

Level it left and right and that’s it you won’t adjust front and back

Yes I could, although the fixings for the vanity unit have already been drilled as they were pretty specific on the height. I know the sealant will hide a bit of the grout line but the front of the sink is about 20mm lower than the back which seems quite a lot to me.

Thanks Shaun, maybe I’m over complicating things. It just doesn’t seem like the fixings are doing much but I’ll try again and concentrate on just left and right.

Your main fixings are the fischer ones

Yes they were, I just tried the brackets to try and support the front. The way the sink is designed, every time I tightened up the Fischer bolts it pushes the Basin upwards towards the back. I wouldn’t bug one of these again I can tell you that.

If there is vanity unit going underneath it can you not sit it on that and then gently tighten it back to the wall using the fischer bolts?

Can you use tile adhesive to pack it out and somehow support it until the adhesive sets? Then tighten the nuts?

Trouble is this may result in a slight gap between the side of the unit and the wall nearer the front corners of the basin.

Take the two bolted on brackets off and lengthen the slots with a file, drill, dremel or whatever to give you more vertical adjustment as they appear to be at the end of their travel.

Looks like you only need a few extra mm (thickness of grout line) of adjustment to be able to level it.

Either that or reposition those brackets upwards by the correct distance using the two unused screw holes instead of the single large bolt.

I'd personally wouldnt of used the wall brackets you have very little movement then if your walls are slightly out of plumb it will throw the basin out , you maybe better to fit the unit first then silicone the corner basin in place once cured you could nip up up the bolts slightly ? If the basin doesn't sit on the unit then remove the wall brackets silicone the basin to the wall resting on the bolts leave the nuts and plastic washers loose prop the front of the basin with tile batten on each corner level it and leave to cure , nip up once cured you will need a plastic packer to pull up against the tile possibly?

The brackets have just been set a fraction too low as you can see there's no more upward adjustment left, that's all.

Put a screw in the corner fixing before you finally tighten the Fischers up.
The basin will be slightly tapered on the sides, so it will release from the mould.
The Fischers will be pushing the basin up as the washers tighten down on the taper

Remove basin.
Put silicon on the wall at the back 2 edges of the basin.
Sit basin back in clips an hold front of basin to correct level with a piece of timber.

Next day go back and gently tighten up the bolts underneath.
