Oxbow16 Posted November 11, 2021 Share Posted November 11, 2021 (edited) Hi all I've got an old baby belfast sink I want to use and I'd like to mount it on old brackets... I've done a mock installation in another part of the house just to see how secure it feels on the brackets and I'm happy with the result. If I put a lot of downward wait on the front lip of the sink, it doesn't budge at all. And that's using the only cr@p screws I could find in the house which were vaguely fit for purpose! So when the time comes to fit it properly... 1. What screws would you recommend I use? Or is it simply the thicker and longer the better? 2. Is there any kind of adhesive or similar I could put between the bracket lugs and the underside of the sink? Because the sink bottom isn't totally flat, there are gaps. I thought some kind of adhesive would help fill these gaps for a better connection, whilst also giving belts and braces stability. More generally, has anyone ever fitted similar and is there any reason I should be thinking twice about doing this?

ToughButterCup Posted November 11, 2021 Share Posted November 11, 2021 I used 120mm concrete screws into our ICF (Durisol) - drilled to 135mm to allow for concrete dust that gets pushed ahead of the screws. I think part of the answer might be to do with the nature of the wall where you want to put the sink. I went to a lot of trouble to make sure that the brackets keyed into the concrete cores of the Durisol - and avoided the woodcrete type 'cladding' to the concrete lattice. You might want to consider mounting a really thick piece of wood as a shelf to carry the sink perhaps? My mum's house had an arrangement like that - gave you somewhere to put bits and bobs (like dirty boots) 1 Link to comment Share on other sites More sharing options...
Oxbow16 Posted November 14, 2021 Author Share Posted November 14, 2021 Many thanks for the reply. We have considered brackets, along with those cast iron legs and bearers. But the brackets we already have would be our preference. RE concrete screws, does that mean no rawl plugs? I was reading about concrete screws the other day - having never heard of them before - but I learnt that they are no good if there is forward force such as there would be with these brackets (plus shelves, TV wall mounts, etc). Any other thoughts or suggestions most welcomes. Cheers Link to comment Share on other sites More sharing options...
markc Posted November 14, 2021 Share Posted November 14, 2021 Type of fixing depends what the wall is made of, as above concrete screws are fantastic into solid concrete or sound brick. sink brackets are fine onto plaster but if dot and dab plasterboard then you need to cutout the plasterboard and add a timber. screws and fixings can be too thick if they are close together.

Oxbow16 Posted November 14, 2021 Author Share Posted November 14, 2021 Sorry, I should have said. It's a solid wall. I think it is probably block, but not 100%. Cheers Link to comment Share on other sites More sharing options...

Cheers No problem, old bricks are often too hard for concrete screws. I would go with 5x75 screws in plastic plugs. If when you are drilling the bricks crumble or you bust an edge off then you can drill oversize and use resin and 6mm threaded rod. 1 Link to comment Share on other sites More sharing options...
ToughButterCup Posted November 14, 2021 Share Posted November 14, 2021 26 minutes ago, markc said: ... then you can drill oversize ... resin and 6mm threaded rod. Thats the one. Drill a perfectly vertical hole (7mm) through a block of wood (2 by 2) Attach that block to the wall, and drill the hole for the bar through that hole. (so the hole is perfectly level) Remove the block Repeat three more times Now you have 4 perfectly level holes for you to resin. Pop the threaded bar in , slip the block over the threaded bar again so you can support the threaded bar with the block Now you have four perfectly level threaded bars ready for your sink. How deep to drill? My guess is 100mm. Use a pooter (blower) and vacuum to clear out the dust. Threaded bar about 75-80mm long. Sit back, tea, medals, Brownie points. Tell her you'll get the plumber to connect up the waste and taps soon(ish) 1 Link to comment Share on other sites More sharing options...
Oxbow16 Posted November 15, 2021 Author Share Posted November 15, 2021 Cheers for all that. I'll hope the block / brick is sound and makes nice neat holes, but if that doesn't happen I'll use the above as a back up. So before we make our final decision... With decent screws and rawl plugs of the correct size and length, do you guys think these brackets would be man enough and safe for such a heavy sink? We will be using it for utility room type things, cleaning veg, etc. And I can only imagine the pain if that were to collapse onto my foot! If we have to we'll revert to plan B which is the cast iron bearers and legs. But we already have these, and we like them, so they will remain plan A if we feel confident they are strong enough. If gluing to the wall or anything else will help make them as strong as possible, then I'm all ears. Many thanks Link to comment Share on other sites More sharing options...
Longwood Posted August 19, 2022 Share Posted August 19, 2022 Hi, just wondering what solution you went for in the end and if it worked? Did your sink already come with holes for the little lugs on the end of the brackets or did you have to drill them. If the latter, was it easy. I have an original sink and some brackets that I would like to use together. Thanks. Link to comment Share on other sites More sharing options...

No, the sink did not have holes for the little round lugs. These brackets are designed for bathroom sinks/basins, on which everything lines up well. I decided in the end to saw off the lugs, leaving a nice flat surface. The brackets were attached to the wall with the largest screws I could use that would fit through the holes. And the sink is just sat on the brackets. The plan was to silicone the back of it to the wall for additional stability but that never happened. Seems pretty sturdy as it is, on account of the weight. Might still do it one day though... Good luck and sorry if you've already done it by now! Link to comment Share on other sites More sharing options...
