  • Step 1:  Remove Your old Basin

Of course, your old basin has served you well, but it’s time to rip it out to make way for the new basin. Unless you don’t mind doing major damage to your wall, your best approach is to take things slowly, and carefully. Don’t forget, you’re not a professional, this is a DIY job, so it’s okay to not finish in record time. Before you begin, turn off the water supply and disconnect the supply lines for the cold and hot valves and the basin trap. If your old basin was attached to a vanity unit, it may be secured by caulking or screws. To remove the caulking safely, take a box cutter or a sharp blade and cut through. When this is done, the unit should be loose enough for you to remove it from the wall safely.

  • Step 2: Place Your new Vanity Unit

Measure your wall and indicate the position where your new vanity unit will be attached. You can use a pencil to make a marking on the exact position you’ve measured. Most vanity units will have openings at the back, but if your vanity doesn’t, you’ll need a good drill to drill some holes into the back of the unit to allow you insert pipes through them. Drill clean holes through the back and be sure to smoothen any rough edges. Proceed to attach your unit in place and be sure to see to it that the fitment is not obstructed but flat against your wall

  • Step 3: Fitting Your new Basin

Now that all is set, and you’re sure your measurements are accurate, the next step is to ensure everything is properly aligned. Before reconnecting your pipes, double-check that they match the holes you drilled into the unit. To achieve a sturdy fit, use your electronic stud finder to locate the studs on your wall and screw your new unit into them. Now that the storage part of your vanity has been properly fixed, the next step is to place the vanity basin on top of your unit. To avoid complications, be sure to fix the waste and mixer before putting your basin in place. Now that your basin is in place, use a silicone sealant to bond the basin tightly to the unit.

  • Step 4: Seal and Test

Check to see if the vanity unit is firmly pressed against your wall then proceed to seal it with caulking for a safe and professional finish. Now that all is in place, switch on the water supply and let the water run through your vanity basin’s mixer tap for a few minutes. This testing process is to check if the water flows freely and to see if any leaks are present. If everything is as it should be, then you can say a proper hello to your new bathroom vanity unit.


Fixing a bathroom vanity basin is no piece of cake, but it isn’t exactly rocket science either.  As long as you have your tools handy and follow the steps above religiously, you should have your new modish bathroom vanity in place and ready for use!
