What adhesive to stick a basin to tiled counter top?

[rcd1976]

Hi,

I've tiled a countertop for a basin and am ready to glue it on, but not sure what the best thing to use is?

The countertop is marble mosaic (50mm x 50mm with 2-3mm grout lines) but the basin is one like this that does not support its own weight:

By that I mean on a flat surface it tips forward. So I'm thinking something stronger than silicone. I was thinking a good ring of gripfill, perhaps with a ring of silicone on the edge for waterproofing. Or should I get some two-part epoxy or something?

Thanks

what size is the base that is in contact with the top and does it rest against back wall?

I have always used silicone but mine have all butted up at the back to the wall.

Hi sorry away for few days, haven't done it yet. It doesn't rest on a back wall. The basin is about 550 x 340 in total but the are in contact with the counter top is about 250 x 170mm, so quite a big overhang and mostly at the front. Thanks
