Wall hung basin

[CDS]

Can I run this one past you and get your opinions.

Just started a complete bathroom refit, walls and floor in 10mm travertine. Have fitted 12.5mm plasterboard to the basin wall (external wall) which has been dot and dabbed with close on half a bag of adhesive per board. This afternoon the customer appears with a wall hanging basin.... my initial reaction..... :yikes:.

I'm thinking neither Travertine or the substrate are anywhere near sound enough for a wall hanging basin? Am I being overcautious or is a wall hanging basin a viable option?

Additional info - Sufficient wall to use Fischer fittings, customer doesnt want visible brackets so additional support isn't an option. Oh, and there's a 3 year in the house.

Cheers Chris

you would need to screw this directly into a dwang in the studwork,i can't see plasterboard holding it

With David on this, although I call a dwang a noggin

 

[kilty55]

i wouldnt risk it either,defo need a fixing

I think you will get away with it, fisher fittings are long enough to get a hold in the brick. if you want to screw them in further (past the flats) put two nuts on the thread and lock together and use them to srew the fittings in further.
(you did say it was dot and dabbed onto an external wall didn't you)

Normally when dot and dabbing plasterboard in bathrooms extra dabs would be used where fixtures and fittings will be going............

Fixings can then be fixed into the wall thru dabs of dry wall adhesive, which avoids the plasterboard being dragged back/bowed when fixing and the tiles cracking.

Can you not remove a section of plasterboard , just enough for the size of the basin and replace with Ply screwed into the wall and then fasten basin to the ply ?

 

[doug boardley]

oops missed the bit about it being a dot and dabbed external wall, struggle to get a dwang in that!!

How big is this basin?

That is an option.

Is travertine stong enough? In my eyes its relatively soft and crumbles easily???

Colour Republic - Basin is 51cm wide and 41cm deep, rectangular.

Travertine wont be strong enough alone, you will need something behind to screw into. Are there screws or bolts supplied with basin ?

There are but I wouldn't use them to hang a bog roll holder!!

 

[Daz]

Is it just me that thinks that the plasterboard is not really strong enough to hold the travertine, let alone a wall hung basin?

 

[DHTiling]

10mm trav.. fine..🙂

 

[Gazzer]

As long as the weight doesnt exceed 32kg then its ok.

 

[Colour Republic]

I take it by your shock you have already tiled the area.

Seeing as the wall is dot and dabbed, I would hang via some extra long basin fixings that will bridge the void between wall and plasterboard, then behind where the basin will sit, drill 3 10mm holes and fill void with expanding foam. This will stop any movement that may occur when then basin is filled with water or a drunk home owner is hanging off it 🙂

I had to look up what a dwang was, I'm:yikes::yikes:
Urban Dictionary: Dwang

 

[White Room]

Thats a Dwang😳

 

[doug boardley]

...suddenly I prefer the term "noggin":lol:

 

[Smudger]

Fixing the basin to a dwang takes on a whole new meaning!! Decent wall bolts would take the weight but I think the movement under weight could cause problems. Will expanding foam be rigid enough? I would also explain dangers to customer, don't see how you could be held responsible if there's problem as you weren't made aware before fixing tiles.

Problem solved - Spoke to cm today about our concerns, they've taken them on board and are sourcing a pedestal...huge sigh of relief from me as I wasn't looking forward to trying to hang this basin!!

Many thanks to all for your responses and words of wisdom, much apppreciated.

Cheers Chris

What we recommend is drilling a 30mm hole into the tile and taking out a plug. Take out the plasterboard if you need to as well.

This photo shows the hole options from the bathroom fitters kit. At 16mm its too pokey. Get the 30mm core out.

Once you have the holes drilled out then look beyond the plasterboard to find a solid substrate like brick or wood. If its just a stud wall then I would go into the room behind, remove the plasterboard and provide a substantial bracket or brace at the back of the sink. Its cheaper to cut out plasterboard in the room behind than take of the tiles.

Oh and if its masonary then you will be able to drill through the 30mm hole without fear of smashing the tile on the wall. If you went for the 16mm then its too close.

A fisher fixing kit pushed through a 16mm hole is too risky.

Pop it through a 30mm and you will get the best view of the substrate behind to ensure a solid anchor

The bathroom Fitters Kit contains both 16mm and 30mm

Note Professional Builder recommend our 16mm when things are easier...

So I would use the 16mm when you know whats behind the wall.

Failing that you could drill out with a 16mm first and then if you need to open out the hole use the 30mm.

Just a thought
