In our prior video, we showed you how to waterproof a shower bench using Wedi.
We also showed you how to install the Wedi Fundo Primo shower pan.
In today’s video we’re going to complete our Wedi Fundo Primo shower kit installation,
and we’re going to show you how to waterproof the walls and install a custom shower niche
using the Wedi building panels.
All right, so we’ll go ahead and put this back panel in, and I’m just going to set
it in place and just kind of put a mark at the edge of my bench here.
And I just measure up from that dado.
Make sure that your tape measure slides down into the dado.
So we got nineteen and a half.
Twelve and five eighths.
Clean the joint; make sure you don’t have any insulation in there or any debris, and
then just fill that whole thing with the Wedi caulk.
So on this backside, I mean, I would say you’re going to almost use an entire tube to fill
this.
But this is the most critical part of this system is getting the corners of the showers,
so you definitely want to be generous with the caulking in this area.
And we’ll go ahead and do our corner and all the way up along the bench.
Push it down into the dado well.
And at this point, I want to keep my first one down about eight or ten inches.
And then you also want to just be, again, four inches away from the bottom.
We’re going to just save some washers and pinch two of these panels together.
Four inches at the bottom.
And then we put some blocking as you remember in this corner; it’s important to have that
to secure the edge.
And again, even though this is just above the bench, I’m still going to keep this
up about four inches.
So this is going to be kind of a little bit of a common thing that you’ll have.
Not if you’re keeping the panel the same, but if notching out and cutting this pan down,
you might end up having a little bit of an overcut for your dado like I did here.
It’s not a big deal.
Once we go to our final application of the sealant, we’ll just fill that whole groove
in there.
So you might not be 100% accurate when you recreate the dado.
Like the factory edge type fits pretty nicely, but I’m about a good saw blade, a good eighth
of an inch off.
So I’m just going to fill that and then fill the corner.
So we’re going to create a niche in the corner here.
But instead of having this weird bump out with our end stud here, we’re actually going
to cut this out so that our wall panels go flush into the side of the corner of the niche,
so basically creating a corner niche.
I’m just going to cut out the area that I want my niche, and I figure we’re going
to make about a sixteen-inch niche.
So I want to start out with the bottom part.
I’m just going to use my oscillating tool, and I want to be careful not to cut the drywall
on the other side because there’s a closet, and I don’t want to do any additional drywall
work.
And since I want it to be sixteen inches on the inside dimension, I’m going to add three
inches for my top and bottom plate plus an inch for my Wedi board.
And I’m just going to add actually another inch for my tile.
It’s not going to be a full inch, but I’d rather have a little bit of wiggle room and
keep that sixteen in there.
So my total overall size will be twenty-one inches; I’m going to be cutting from bottom
to top here.
Truth is this is sitting straight.
And you also want to make sure that this is sloping into the shower.
So if you have to, you can put a shim in the back here and create that.
But it’s nice to have the wood blocking actually slope into the shower.
It makes everything else go in more easily.
We’re putting in wood blocking here.
This is just standard 2x4s.
You can use 2x6, 2 by whatever.
We’re using common deck screws to secure them to the studs.
The reason for the blocking is for grab bars.
We do the caulking on top of this bottom sheet here.
And then we’ll be able to pinch both sheets together here.
And, yeah, I’m going to keep this down about eight inches so I can pinch those two sheets
as well.
I also got to pinch two and a half.
So make sure that sits on the dado and then you can just puncture against your mixing
valve or where that location is, you know, to give you a center mark.
Kinda trace this guy around here.
And then move onto your next piece.
So now we know that’s the center of that.
I’m going to use a one-inch spade bit to cut that out.
Then your next one.
Now this guy, you just have a two and a quarter, but you can cut this out with a utility knife
obviously, but I have a two and a quarter hole saw bit.
It’ll cut out.
Clean out that dado joint.
And on your corner here.
So we measure down to the bottom of our niche and cut this out.
Seventeen and a half.
Okay, so I would recommend for doing this, custom-making a niche, to put the bottom of
the sill plate down first.
Finish the size.
So we got basically ten inches.
So cut it off a square inch here; ten inches.
Notch up a little bit out.
Okay and then seal the bottom part of the Wedi here.
Just make sure it’s still sitting level when tented down.
And actually it might be a little…
there we go.
Put the back portion in.
There’s like nine and three quarter.
Seventeen.
So I’m actually going to use up the rest of this thinset.
Again, you can either use sealant against the drywall or just use some thinset like
I’m doing here.
Going to get a good amount of sealant against this bottom plate.
Okay, and then make sure you seal against the Wedi bottom sill.
And I can’t really get in this corner, so I’m just going to go against my one-inch
here.
Steve is using a scrap piece of 2x4 here to pound that little piece of Wedi panel into
the 2x4s.
Then he’s using two screws and two washers to attach it.
Now here’s the thing: always make sure you apply a copious amount of Wedi joint sealant
in a custom shower niche like the one we’re building.
Thirty-five.
Put a generous amount on this bench we’re going to slide the panel into.
And again, I’m not going to go all the way down to the corner; I’m just
going to hold that last one up.
So now it’s time to apply a generous bead of Wedi joint sealant to all of the seams,
all the vertical seams.
As you can see here, Steve is using the corner putty knife, and that really comes in handy
with the corner seams, and applying a lot of Wedi joint sealant to that custom shower
niche.
Again, that’s really, really important to keep everything nice and waterproof.
And then applying Wedi joint sealant to all the screws and washers.
So again, you want plenty of Wedi joint sealant in between all of the seams, especially add
a horizontal plane for a bench.
That’s very, very important.
And then again, were just smoothing out the joint sealant so that it doesn’t affect
our tile.
You can see here how there’s plenty of joint sealant on all the seams in the custom niche.
And then we applied a lot of joint sealant on all the screws and washers and horizontal
seams.
It’s very easy to use the joint sealant; you just go from one screw washer combination
to the next and from one horizontal seam to the next.
And it’s easy to smooth out with either a three-inch putty knife or that corner putty
knife.
You’ll probably want both of those for a shower system like this.
Again, make sure where the curb meets the bench or a side panel that that’s completely
waterproof.
And then it never hurts to apply a lot of Wedi joint sealant between the curb and the
shower pan and between vertical building panels and the shower pan.
These are areas that could be adversely affected by water, so always make sure that they’re
completely waterproof using the joint sealant.
So this is one thing that’s different than most other pans is that if you get a little
puncture like this, you really don’t have to worry too much about it because this pan
is an inch and a half thick.
This was actually just from one of those washers.
I stepped on it and kind of created a little pin hole.
But you can just fill this in with the sealant and not worry about it.
I would say this is one of the real great benefits of using the Wedi system is because
if you puncture this, as long as it doesn’t go all the way through the pan, I mean there’s
still waterproofing; you don’t have anything to worry about.
Whereas a lot of those other pans where it’s a sheet membrane, you’ll have a major issue
if you did a puncture like that.
So even like this little divot here, I must have dropped something there, so I’m just
going to fill in that little hole, and we’re good to go.
So if you wanted to, and you worry about waterproofing this area because, if you remember, we kept
this corner because we didn’t want to damage it and have to do all this finishing on the
outside, but if you wanted to, you could just use a sealant and go over this whole corner.
It really is not going to matter because, if you remember, we’re going to have that
shower door coming possibly three inches away from that corner.
So technically it’s not going to be in the wet area outside of here.
But if you had some extra sealant, and you were concerned about it, it’s really not
a bad idea to fill that in and just seal over this and then the whole area is waterproof.
And then the same thing as far as the ceiling.
If you really wanted to seal up against there, you could.
But there’s really not going to be, you know, you’ll be putting tile and then you’ll
end up doing a caulk joint against tile.
I mean if you’re getting water way up there, you really should’ve considered doing the
whole ceiling with tile as well or at least in the shower area.
But normally, that’s not really much of a concern because it’s really kind of out
of the wet area.
Okay, and then all the kits come with this escutcheon rubber plate that you would basically
thinset into place.
And this is just like a lot of extra protection.
Because if water ever got behind here, you have this big rubber gasket, essentially,
that’s going to keep the water from going inside the wall.
So this comes with every kit.
You can do this during the tiling process, or you can install it as you’re installing
the Wedi kit.
But basically just use a thinset to set this in place.
And then make it as flat as possible.
Okay, and then they also have these little guys, which is really nice for something like
this for the shower port because this is definitely an area that if you didn’t silicone around
the port for the handheld, this really makes a nice seal on that.
So if you bought this shower kit and then you have an additional valve like this that
changes it from showerhead to handheld, they don’t really sell another flange like this
for something smaller like that.
So what you want to do on this is, literally right around the edge, just basically create
a bead of sealant, just enough to raise it outside of the Wedi board, and then let that
dry.
And then you’ll tile up against that.
So when you’re really just trying to create your own little bead so if water ever got
behind, which it will eventually, once water gets behind the tile, then that water can
run down and go outside of this hole.
So just try to make it as close to that valve as you can.
That will be the same thing you want to do for the showerhead if you didn’t buy an
additional flange for it.
So I’m kind of making a mess here for it, but you just really want to…
It’s more important on the top than it is on the bottom.
Using the Wedi Fundo Primo shower kit is very easy and straightforward.
