Connecting a wall-mounted sink to the water supply and drainage outlet follows the same principles as for a pedestal sink.  However, because the pipes will be visible with this type of bathroom sink, there is more work involved to hide the pipes or make them appear more attractive.  Also, the way in which the sink is fixed to the wall is different.  Try to use a waste system that matches your faucets, ie in chrome, for a more attractive finish.

If you're fitting your sink to a solid wall, you will need to cut out a channel for the pipes.  Using a pencil, mark the proposed position on the sink on the wall and draw lines downward to show where the pipes will go.  Then, make the channel, using a club hammer and bolster chisel.  Take care to wear protective goggles and gloves when making the channel.  When you've made a deep enough channel, the supply pipes can be routed to the correct position.

With hollow walls, pipes can be routed through the cavity, but often it's easier to simply cut out a section of plasterboard rather than making large access holes.  Because the sink will be heavy, it may be necessary to fit and extra nogging in the studwork to adequately support its weight.  You will need to measure carefully and make the exact spots on the wall where the brackets that support the sink will go before fixing one or more noggings in place at the relevant height.  When you've positioned the pipes in your stud wall, place insulation blanket between the stud, nail plasterboard over the area and dry line or plaster it to achieve a smooth finish.  Remember to make access holes so the pipe tails can protrude into the room.

To attach your sink to the wall, use a spirit level and pencil to mark where the brackets need to go, and screw the brackets onto the wall.  On a hollow wall you should be able to screw directly into the wall.  On a solid wall, you will need to use wall plugs with the screws.

Before you hook your sink over the brackets, you'll need to fit the faucets and waste.  The sink will have pre-drilled holes beneath it, through which you can screw it into position.  Once you've got your sink in place, you need to work out how much pipe you need to connect the waste to the trap, then cut out the desired length of pipe and connect it.  Lastly, connect the sink faucets to the hot and cold water supplies and your sink is ready to use.
