I am installing a benchtop in my laundry that is completly tiled. Does it matter if i install the benchtop against the existing wall tile or should i remove the tile were the benchtop touches the wall and replace the tile (backsplash)?
Is there any downsides to just fitting it directly on the exsisting tile?
Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thank you for sharing your question about installing your benchtop against existing subway tiles.
The typical depth of a laundry cabinet is around 580mm, most benchtops are usually 600mm in depth. When the benchtop is placed on top of the cabinets, there will be an overhang of at least 20mm. If for example, we were to estimate the thickness of the subway tile plus the glue, it would come around 8 to 10mm. If you install your benchtop in front of the tile, you would have to add that thickness to the overhang. Instead of having a 20mm overhang, it would now be 30mm.
I don't see any downsides to your proposed installation. Once the benchtop is pushed against the tiles and is secured onto the cabinets a bead of silicone will provide an adequate seal between the tiles and benchtop. However, consideration must be made for the size of the laundry tub and tap if you're installing any. It sounds like a laundry renovation!

We installed our bench top up against the existing splashback. The tiles were white and laid well with no drummy tiles. Our taps were wall mounted and the sink was over the bench top. The result is great.
