Planning & preparation

  • When deciding which taps to buy, take into consideration your sink unit. To accommodate mixer taps, your sink unit only needs one tap hole. For separate hot and cold taps, it needs to have two holes
  • Make sure the water supply is turned off before you remove an old sink and tap, or fit new ones

Do it right

  • Spanners and screwdrivers can easily scratch chrome taps, so where possible use a soft cloth to protect the finish
  • It’s important not to over-tighten a washer or valve when assembling, as this may damage or cause excess stress on the joint

Staying safe

  • If replacing an old sink and tap, make sure you turn off the water to the area before attempting to remove them. Also, avoid lying directly underneath when removing the old sink, as small parts may fall down during the process
  • This guide is designed to help you safely through the process of fitting a sink and tap. If you’re in any doubt, please seek advice from an expert and always follow manufacturers’ instructions

Aftercare

  • Always use cleaning products that are appropriate for your chosen sink and tap to avoid damaging the materials. You should be able to find guidance for this in the manufacturers’ instructions

Step by step

Step 1

Position the sink upside down on the worktop where you would like it to be located and draw around it with a pencil.

 Guide Step
Step 2

Move the sink and draw a second line, about 10mm – or the depth recommended by your manufacturer – inside the first line.

 Guide Step
Step 3

Use a 10-15mm drill bit to make four holes in the corners of the inner line you’ve drawn.

 Guide Step
Step 4

Place your jigsaw blade into one of the holes and cut carefully along the inner line. Support the area of worktop you are cutting around so that it doesn’t drop down.

 Guide Step
Step 5

Remove the cut area and treat the edges of the worktop by brushing with a waterproof sealant and leaving to dry.

 Guide Step
Step 6

Assemble the sink, tap and waste unit using the manufacturer’s instructions.

 Guide Step
Step 7

Position the sink using either the supplied edging strip or a bead of silicone on the cut edge of the worktop. Then use the supplied clips to fix the rim on the underside of the sink to the worktop, using two on each side. This will secure it in place.

 Guide Step
Step 8

Use flexible connectors to attach the new tap or taps to the existing supply pipes, applying PTFE tape to the thread of the pipe, to help create a watertight seal.

 Guide Step
Step 9

Turn the water back on and check for any leaks – tightening the valves with a Monobloc tap box spanner if necessary.

 Guide Step
Step 10

Run a bead of silicone along the back edge of the worktop and smooth it down with a sealant finishing toolfor a neat and watertight finish.
