I have a very small cloakroom basin that needs to go into a waterproofed vault. This is a resin basin 500 x 145 mm x 90 mm high with NO pedestal. http://www.benesan.de/?mcat=1&cat=mineralpour&prdct=37&lang=en It is meant to be fixed into the wall along the 500mm side however this wall is a tanked (Delta Membrane), then skim plastered and then tiled wall. Delta Membrane highly recommend NOT to fix through the wall and avoid wherever possible (there is a very messy solution with this which i am trying to avoid though). I can possibly fix it on the 145mm side as I have a studded false wall which is also housing the cistern to my toilet. So the question is - would it be OK to fix along the short length and use a glue along the long length to the tiled wall? And what glues would be recommended? As an additional option (although preferred to avoid it) I was also thinking of fixing an L shaped bracket to the back to the backside as well.
Difficult to advise really. Normally would fix with a basin fixing kit screwed into the wall and sealed with silicone. I always use Dow Corning 485. Silicone only, I wouldn't risk it
If you had a pedestals would say yes as that can take the weight. You will end up leaning on it and ripping halfthe wall off with the basin.
I wouldn't recommend it unless it's your own house and know not to put too much weight on it...however, we do use a product called sealfix... The guy came into our plumbers merchants, put a brick in a bucket of water, put sealfix on a door handle then squeezed the 2 together (underwater) for 5mins then lifted the brick out by the handle
We now use it for all sorts of jobs, sticking toilets to floors and stuff like that...the stuff is the nuts...but I've never tried free hanging anything with it for extended periods http://www.amazon.co.uk/SOLVALL-SEALFIX-AVAILABLE-WHITE-CRYSTAL/dp/B00IMI5GT2
I would go with CGN 's recommendation , at the end of the day if you have siliconed the screw holes you will get no problem unless your cloakroom happens to be inside a submarine!
Ah I only just realised what you meant by siliconing the screw holes lol...I thought you meant fill the holes in the back of the basin with silicone to fix it to the wall! Sorry I've not been sleeping much...got a 3week old baby!
I appreciate everyone's advice and responses. the guys selling me the basin was confident it wouldn't be a problem gluing it to the wall..... I wasn't convinced and you have all helped me ignore his advice
