How to Install a Wall Hung Vanity. Owner Builder Series, Ep.51

(upbeat banjo music) – [Uncle Knackers voiceover]
G’day Knuckleheads, Uncle Knackers here and welcome to Episode 51
of my Owner Builder Series, and in this episode I am going to show you how I install a wall hung vanity. I love these vanities, they
look good and they also give the illusion of space, so in
my book that’s two big ticks. – That’s looking good, can’t
wait to see it installed. Installing a wall hung
vanity can be a bit tricky, especially if you’re doing it by yourself, because it doesn’t go down to the floor. So you need to be able to support it, while you attach it to the wall. So to make that job easier, what I’ve done, is I’ve made this support out of some old pine scraps
that I had lying around. This is built to the correct height, so all I need to do is to get my vanity, place it on top of this frame. That’s then fully
supported and that gives me the flexibility to move it
around from side to side, and do what I need to
attach it to the wall. It’s a good technique, give it a go. Now with the vanity fully
supported by that frame work, it now makes it so much easier to be able to position it, get it nice and level, cut the holes in the
back for the pipe work and then secure it, hard
up against those tiles. Too easy. Once you’ve got your
vanity sitting exactly where you want to it go, first thing you need to do, is to level it up. You may need to adjust that, if you do, just put some packers
on top of that frame, on either end, get that nice and level and then you’re ready
to mark out the position of your pipework on
the back of the vanity. You can see the pipes
coming out of the wall behind the vanity, all I
do is get my tape measure, measure down to each pipe, find out what that measurement
is, to the top of the vanity, and then transfer that
line across the front, mark it, and then drill those holes. Now just pull the vanity
back a little bit away from those pipes, so that we
don’t drill through the pipe, when we go through the back of the vanity. You can remove the whole
vanity, place it on the ground and do it, but this is
so heavy that I can’t get it back up on to the stand by itself. So I’m leaving it on the stand, and doing everything in situ. So let’s open up that cupboard,
and drill these holes. Now just get this last hole drilled. Alrighty, now hopefully, fingers crossed. This should slide back on those pipes, all three of those pipes. And there you have it. Now that turned out absolutely spot on. Now all we need to do,
is to attach the vanity, to the wall. And luckily
before this was sheeted, I marked out on a plan, exactly where the studs are on this wall. So I can simply just drill the
vanity into that stud work. And it’s also a good idea,
as well as marking it out on a plan, to take a few photos, that way you know exactly where all
the pipework is as well. Because you don’t want to be drilling through those water pipes. No you don’t. Now before I attach this to
the wall with the screws, I just wanna mark out, the
corners with some tape, just like this, so I know exactly where the vanity is going to be going. Because I’m going to pull the vanity out, from the wall, so that I can put some silicon behind this, to help secure it. So when I put it back against the wall, these pieces of tape
here, will show me exactly where I want the vanity to go. Pull it out, like that. Now go and get a rag, and clean off all that dried-up grout, like that, because you want the silicon to stick directly to the tile, and not to the powdery dried-up grout. There we go, that’s pretty good. And get down there, that’s it. And now, with our silicon, put on some, no, hang on a second, just put some dobs of silicon, right along the top,
sides and in the middle. Now, down the side. Seriously, once this
gets screwed to the wall, it’s not going anywhere. Just pull it out a fraction
more, so we can get in there. Don’t be shy with the silicon, nice big dobs, like that. Alright, now we can slide
the vanity back, to the wall, lining up with these
marks, our tape marks. Now that, is beautiful, Now all we need to do, is drill the holes for our stud work, and
screw this to the tiles. So first of all, I’m just
going to drill through the vanity, using a wood bit. Like that, I want a stud there, put a stud here, and a stud over here. Okay, now I get my masonry bit. I’ve got two sizes here,
one’s a bit smaller. So I go through that first. I just wanna go through
the vanity, the tile and the villaboard behind
the tile, and that’s it. And that’s it. If I was putting in a plug, I
would put one more drill bit in there, just to make it the right size. With the hole drilled, I just wanna do a bit of a countersink. Like that. Put in my phillips head bit, and then screw to the
stud behind the tiles. And that is beautiful, and
you can see how the silicon, is squeezing out behind the vanity. That is absolutely spot on. Now just repeat that process on each stud. Now I have to say that it can be, just a little bit scary doing this, because you just don’t
wanna drill through a pipe. No matter how much planning you’ve done, you’ve always got that
in the back of your head, or the back of your mind. Did I mark it out properly? Or maybe that’s just me. Now if you’re not sure, you
could put a bit of tape, on your drill bit, the
depth of your vanity, tile and villaboard, that way you
won’t drill through too far. Another screw. Beautiful! Now to get the screws in the same line, down the bottom, just
use a square or a level. And remember, if you go
right down the bottom, you’re not gonna hit a pipe, up the top you’re not gonna hit a pipe, and down the bottom you’re
not gonna hit a pipe. This is where all the pipe
action is, across here, so just steer clear of putting any screws, in that sort of area. Now what you did across the top, just do the same down the bottom. Now because there isn’t
a stud on the corner or the edge of the vanity, I’m just going to use some plastic plugs. Now it’s exactly the same deal as before, we drill through the
vanity first, then put our masonry bit in, go through the tiles and then insert our plug. Now I’ve taken the draws
out for easier access. Now a masonry bit. That’s it. I’m going to go one more size
up, with our masonry bit. Now all you have to do is to
get your 6 1/2 ml plastic plug, and just tap it into the hole. And I use another one, just
to drive the inner touch, and then, you can counter sink the hole if you wish. You don’t have to. I just do it for looks. If you don’t care about
looks, don’t do it. And then all you have to do is, put your phillips head back in, and insert your screws. And that is now done. Repeat that down the bottom, and the vanity is now secure to the wall. Now that was pretty easy, wasn’t it? Now as far as the top
goes, don’t put it on yet, until the plumber’s been in
and attached all his pipework, because it makes it
easier for him to do that, rather than getting under
it and doing all the work, he can do it from on top. And to put the vanity top
on, just place it on top, and then get inside and
run a bead of silicon along the inside edge, and that
will hold it down beautifully. And that is how to install a vanity. Great tip Knackers! Well I hope you enjoyed and
found that video useful. And as per usual a big thumbs
up is greatly appreciated, and if you haven’t already please hit that subscribe button for more handy tips. Alrighty, I’m off for a cuppa tea, so till next time, I’m out of here. Cheers. Just one more quick
thing before I move on, if you want to put the top down before the plumber gets there, you can. There’s no hard and set
rule saying that you can’t. It’s just easier for the
plumber if you don’t. Anyway, if you do decide to put it down, put it in position, this is heavy, just like that, and once you get it sitting
just where you want it, which is just there, get some silicon, a tube of a silicon, and hop inside your unit,
and in various spots just run a little bead between the vanity and the vanity top,
once that silicon dries, and the trap is connected to your sink, this top isn’t going anywhere. Good luck.


  1. Episode 51?? I thought we were done…

    There is a Santa Claus!

    cant believe how poyfect you centred those service holes Shane!

  2. I sympathise with you Shane. You spent so much money on getting the house built, you could not afford at least one extra drill. One for the drilling holes and one as the driver. I'm a show off and have a third cheap Ozite from Bunnings with a countersink permanently attached. Thanks Uncle Knackers ;0

  3. Well done, Shane. I might be missing something here, but without any floor support you are counting on the particle board sides and a couple of middle supports to hold this up?

  4. Great job Shane.

    My problem with anything like this is that I never have confidence of just how much weight the screws can carry and end up over-engineering. I would probably end up doubling the amount you put in here.

  5. GREAT tip Shane building the base. Also makes sure all the vanities are at the same height throughout the house.

  6. I've never installed a hanging vanity, so in my inexperience my first worry is that the weight of the installed vanity and top would trap the wood support underneath. Or is that just the way things go with my installs? 😛

  7. That was a great tip knackers, and thanks mate for another ripper vid, i always look forward to you're new stuff Shane. Cheers

  8. Great Video and Tips as usual from you Shane. Your house is looking better and better now, well done to all that was involved.

  9. Shane, wouldn't it be quicker and more efficient to drill all the holes through the vanity first, then drill all the tile holes and then the counter sinks. Changing the drill bit each step for one hole seems to be time consuming and you being a contractor, know time is money.

  10. Great tip marking those studs on your plan Shaneo, pro tip for all the punters out there! Looks awesome mate, hope you got the feet up over Christmas and enjoyed it.

  11. Hello sir! Thanks for this video. I want to have a floating vanity as this one but I fear everything will go down once that platform you place under is removed. We have a solid concrete wall with marble tiles. I'm not quite familiar with what you refer to as studs. Our house is newly built and I'm guessing we don't have those studs on the wall, is this installation still possible with that kind of wall? What screws should I use and how much weight can how many screw support? I think it'll be quite heavy, it'll be 100cm long 55 cm wide granite counter top, porcelain wash basin and wooden cabinet.. I'll very much appreciate your reply. Thanks

  12. Shane, thanks for this, I'll be hanging one myself soon. Two questions: unit only hanging by thin screws (plus silicon grab), not some heavy duty dynabolt-type fixings? People lean on those vanities sometimes . . . .
    Also, not worried about masonry bits cracking the tile, even if no hammer action used? i.e. no need to use a diamond bit to go through the tile?

  13. Awesome video , thouroughly explained . I’m about to install one myself . What screws did you use ?. And what ones are ok to use for strength ?

  14. Two common questions for my bathroom reno:
    1. If my waste goes to the ground, what is the usual process for wall hung install (ie. dig up pipe and route up in wall (single brick); leave as is as it will be hidden unless looking underneath; don't go a wall hung vanity!).
    2. Tile before or after vanity?

  15. I have a couple of problems with this; 1. It looks like pressed board (melamine). I would install a wall hung vanity with only plyboard sides and back board. 2. never use counter sunk screws to fasten to wall, use only cabinet screws (washer head), especially in pressed board.
