• Measuring the available space is the essential first step when installing a worktop vanity unit. You should consider not only the dimension of the space but also ensure it allows for proper clearance around it once installed. 

• Always open and check the freestanding worktop vanity unit as it arrives. So, you can return or replace in case of any problems. Ensure your worktop vanity unit includes everything like the handle, basin, screws, waste pipe, and basin taps (often ordered separately). 

• Having the right tools in hand will make the installation process smoother and more efficient. Ensure you have all the tools available listed in the next section. Refer to the manufacturer section for the instructions.

Step-by-Step Guide

If you have everything ready and planned let’s, get started with the worktop vanity unit installation process.

Remove the Existing Bathroom Furniture or Storage Unit  (if applicable):

It’s obvious that you will remove the existing vanity units first before installing the new ones. As the same rule for every plumbing task, turn off the water supply valve under the sink and disconnect the flexible hoses connected to the shut-off valves using a wrench. Once done with disconnecting the plumbing, you can remove any screws or fasteners that secure the vanity unit to the wall. 

It’s obvious that without the removal of the existing vanity unit, a new worktop unit can not be installed. As is the same for every plumbing task, it is important that you turn off the water supply from the valve from the main water supply line.  

Prepare the Installation Area:

Once the old vanity unit is removed, it’s time to start preparing the area for the new unit. Begin by cleaning the floor where a new worktop vanity unit will be placed.  Remove all the debris and ensure the surface is levelled. Placing a protective mat underneath is a good idea to prevent scratches during the installation process. 

Assemble the  Countertop Vanity Unit (if necessary):

Most worktop freestanding vanity units in the UK come pre-assembled, while others may require some assembly. Follow the instructions provided by the manufacturer in order to assess the vanity unit. It may involve attaching the doors and legs (if it has) drawers installation and 

Position the Worktop Vanity Unit:

You can now place the assembled unit at its designated location for fitting. Don’t forget to utilize the measurements you took earlier for proper placement. The unit should be levelled and perfectly even on the floor. If your vanity unit has adjustable legs, use them to fine tune the level. 

Mark the Mounting Holes (if applicable):

A freestanding worktop vanity unit usually does not require wall mounting. However, in some cases your vanity unit will have pre-drilled holes for additional stability. If your countertop vanity unit has pre-drilled holes, then use a level and a pencil to mark the corresponding spot on the wall to drill the pilot holes. 

Drill Pilot Holes

You will need to drill the holes on the marked spots. These holes will prevent the wall from splitting when larger holes are drilled for screws. Additionally, these holes ensure precise and secure fitting for screws that will secure the vanity to the wall. You should drill slightly smaller holes then screw straight into the marked spot on the wall. 

Install Plumbing Fixtures

It is important to install plumbing fixtures first before positing the sink on the countertop vanity unit. This may include attaching sink tap, drainpipe, or any other accessories like overflow drains. You should check the manufacturer's instructions if it's available. All the connections should be tight and secure using plumbing’s tape or threaded connection to prevent any leakages at a later stage. 

Connect the Plumbing

Now, carefully lift the worktop sink (with pre-installed fixtures) and position it on top of the vanity unit. Make sure it is aligned with the drain and faucet hole when fitting. Connect the water supply lines, and the drain pipes to the corresponding connection on the shut-off valves and the drain system beneath the floor. 

Secure the Worktop Vanity to the Wall (if required):

Worktop vanity units with pre-drilled holes will need to be secured on the wall with screws. Simply line up the screws with the marked holes and drill them to the wall using the appropriate drilling bit size. Once in place, tighten the screws while avoiding over-tightening, preventing potential damage. 

Install the Sink and Faucet

You can now finalize the sink and faucet installation after securing the worktop vanity unit at the right position. The process may slightly differ depending on the type of sink and faucets. However, most of the time it involves applying a bead of silicone caulk around the rim of the sink where it connects the countertop for a watertight seal. 

Seal the Edges

Inadequate sealing may result in water seeping out from the sink and vanity top. You can prevent it by applying a bead of silicone caulk around the edges of the countertop sink where it connects to the countertop. A smooth caulking tool is essential to create a clean and even finish. 

Check for Water Leaks

Once everything is in place, it's time to ensure any potential water leaks before putting your new vanity unit to use. Simply turn on the water supply valve and open the faucet. Inspect all the connections around the faucets thoroughly. Look for signs of water dripping or pooling underneath the sink or vanity unit. In case of any leaks tighten the loose connections or reapply the plumber’s tape as needed. 

Clean Up and Finishing Touches

You may start cleaning up the worktop installation area once you have ensured there are no leaks. Remove the debris, leftover tools, or caulk residue. Finalize the process with a wipe down the vanity unit and the sink with damp cloth to remove the dust. To give it a finishing touch consider placing towels, toiletries, or decorative items on the countertop or drawers. 

Congratulations! The installation of the worktop vanity unit is complete. Now take a moment to admire your DIY skills and enjoy the elegance and functionality your freestanding unit brings to your bathroom.
