The installation of the sink cabinet was per IKEA instructions. Our builders cut the wood slab to size and attached it to the vanity with small brackets. Since it is used in the bathroom, we got a slab that was treated.
As for the plumbing, it needed some creativity.
If you look online for space savers for plumbing (waste) you will find a variety of items where you can direct the water from the basin diagonally along to the back wall, which allows for free movement for the drawers.
Other than that, our builders did the usual plumbing installation: cut a hole in the timber slab for the drain pipe, setting the sink and sealing everything well.
This is a solid vanity and we adore how it all looks together.
Another wood slab and stone basin for the second bathroom vanity.
