Hi members,
The wash basin in the bathroom has come loose. There are no clamps underneath. Can someone pls guide me how to fix it?
Welcome to the Bunnings Workshop community @arq. It's wonderful to have you join us, and many thanks for your question about fixing a sink.
If your bathroom basin has come loose and there are no clamps underneath, it’s likely that the sink was originally secured with silicone adhesive. To fix it, you'll first need to disconnect the plumbing. This may require a plumber to help you disconnect the water pipes so the basin can be lifted slightly.
Once lifted, you’ll have access to the area where the basin meets the benchtop. Carefully scrape off any old silicone with a plastic scraper or silicone remover. After cleaning the surfaces, you can apply a fresh bead of silicone under the edges of the basin where it meets the benchtop. Carefully lower the basin back into position and press it down firmly to ensure a good seal. If you want a simpler fix, you could also try applying a new bead of silicone around the outside edges without lifting the basin, though this may not provide as strong a hold as removing the old adhesive. Allow the silicone to cure fully before using the sink.
Here's a helpful guide: How to apply silicone sealant.
Please let me know if you have any questions.
