🤔 Linear drains for tile showers explained👍

By Grover Koelpin 35 comments

okay so in this video I wanna talk a
little bit about linear drains they’re becoming very popular and the reason for
that is because they open up a whole lot of the possibilities for the use of
other types of tile other than mosaic tiles if you’ve got a center Center
drain or a point drain you have to slope the entire floor to that drain so that
limits the possibility of the size of tile that you can use to be able to
conform to that slope or that pitch or that bowl shape it in the on the shower
floor when you use a linear drain now you can put the linear drain either on
one end on the back wall or even near the curb or you can even eliminate the
curb altogether you can also do that with with the regular point drain but
the linear drain opens up possibilities for tile sizes when you use a linear
drain you have a flat pitch you don’t no longer have a bowl but you have a flat
surface that is pitch to the drain so if you have say the drain and the back wall
you have the pitch from the front of the shower where the curb is down towards
the back or you could have it on one side of the shower and you would have a
flat pitch a flat surface pitched towards the side of the shower
where the drain is and because the surface is flat what that means is you
can put any size tile you want if you can get a big enough tile to be just one
piece you can do that the only thing you want to be careful of is you don’t want
the floor to be slippery so you’re gonna have to pick the right kind of tile if
you’re gonna use a large format size tile you want to pick the right kind of
tile so that you don’t slip and it doesn’t become a hazard there are
plenty of tiles like that that’s probably a topic for another video when you’re
using most mosaic tiles that’s not a problem because
there’s a lot of grout lines and that gives you traction so when you have
these linear trains you can use large format tiles 12 by 24 whatever size you
want and because the pitch is flat so in this video I’m just going to go over the
you know the one that I use the most which is a Schluter drain now there are
plenty other types of drains you can clean your drains that you can use the
one I use the most is its Laura because it’s one of the easiest you can you can
use plus it’s the most available to me so a lot of this that you see in this
video is actually applicable to other types of systems I’ve use other systems
but as I said the Schluter system is the best option for me because just the
availability for me it’s again just to make things clear sure that doesn’t pay
me anything I don’t get any money from Sula I do these videos on my own accord
and this is just real real installs that I do for customers that I choose the
materials they choose that their tile and I choose the system that I’m gonna
be installing and as I said Schluterr is the easiest for me to get it’s the one I use
and besides that it’s a great system why not use it it’s a fabulous system
it works really well they have a good reputation so I use it and but like I
said I don’t get any money from them the reason that you see a lot of videos that
have Schluter is because that’s what I use so it’s just a process that I use to
install the drain body and the drain grate to get ready for the tile floor if
you you know just want to refresh or you just want to see how it’s done this is a
good video for that I have several other videos that go step by step and into
great detail on how to do it and I’ll link to those in the in the cards and in
the in the description below and so this is just more like a major steps type of
thing so you can get an idea of what’s involved in installing one of
these linear drains so anyway so as usual and don’t forget to subscribe and
also check me out on patreon it takes time and effort to make videos if you
can support me that’d be that’d be great also most of you know some of you might
know that I have an online store this matcom where you can purchase a lot of
tools especially the T lock system that I use on my my website and I also have
available a PDF available for download it’s just a small fee if you’re
interested in that it just gives the the important steps or the a guideline on
how what needs to be done to install a floor properly either on plywood or
concrete it’s not specific but it’s very useful in the sense of understanding
what needs to be done I will be making other PDFs in the future soon as I get
the time but anyway I hope you enjoy the video and as always and most importantly
don’t forget to subscribe thanks a lot ok so let’s talk about linear drains
this is a linear drain it’s gonna go in this shower in that corner over there
there’s a there’s a template board that I put in there when I did the mud that’s
gonna come out and this is the drain now now linear drains are becoming very very
popular for me this is probably like the fifth one or a row that I’ve done so and
Schluter makes probably one of the easiest systems to install but they have
foam pads foam trays that you can use instead of the of the mud and but I like
doing the mud for me it’s easier because you know just it for me it’s
just easier because I don’t have to work you know cut the at the foam you just
put the mud it fit it fit any size whereas the foam trays you have to cut
the size and make them fit or extend them or whatever so I just like to do
the mud but the foam trays will work if that’s the way you want to go this is
actually drain grate this is this one here the solid body and
they have the perforated than tilable and they have a few new ones as well a lot
fancier but these are the standard ones that I’ve been using it comes with a
valve seal inside outside corners I’ll show you in a minute that it comes with a valve seal
right so this is the drain grate so this is the drain grate right here
I’ll pull up in a second and this is the drain body this is the part that gets
buried see so already open this up once but open it up again this is the drain body it already has the membranes installed on it they just
put into place that comes with the collar that come foam the foam foam if you’re
putting it in the middle of a shower then you use this part here if you put
another thing at a wall then you don’t use that this will go like that and when
I put make these templates here I make them slightly bigger when I install it
so anyway these the linear drains that I use so you know
the other manufacturers make them without the methods and other systems to
install it but this is the one I use the most so I pick these out and show you
how okay so when you’re installing these you wanna make sure you don’t close that
up so that the grate drain doesn’t fit and this comes with these pre install
just adjust the height of the drain grate you can move these over like a
little slot in there and you can put them wherever you need them put one here now move this one over put it about here so now that you can’t close that up and this one here i s pretty stiff to these foam inserts
that you could put in my kept those because they come in handy but if you
don’t have one those you can just make one out of a piece of kerdiboard and that
will keep it nice and tight and what i do when i install this i put this on and then I’ll just tape it on the top so it doesn’t fall
out so that’s the drain grate and then these and go screwed in here and that is to adjust the height
of the of the grate in relation to the drain body to give you the correct
height for the tile perfect

When the drain is installed close to a wall is the wall tile installed sitting on the shower base and grout fills the space between wall tile and drain?

So would this be a solution from turning a bathtub to a shower, since you'd want to center the drain if it were a regular drain? But with this it wouldn't have to be centered.

Sal how do you dispose of wast water after clean up from gout/thinset? Down the toilet and give it a couple flushes to rinse everything down? I also have a wet saw I'm cleaning up after too.

You absolutely make the best videos about installing tile, Kerdi board and drain systems!! You explain everything so well. One question I have. Do you use Kerdi board or the liner under the mud?

Sal, For the small area off to the edges of a linear drain, do you form your mud bed to have slope into the drain or just build up the thinset to slope the tile?

Is that foam piece that goes in around the edge a pre pitch piece to direct water out of the corners of the shower? Also, it should be mentioned how much a line drain adds to the cost of a job. In addition to relocating your drain (which may/not need to be done anyway) the drain system itself is around $700 as opposed to a center drain that might be $50-$100 or included in the system you're using. We were going to use a line drain, but we're using cut river rock so it's basically a mosaic, and once I saw the cost it became a law of diminishing returns thing…If I had to use a line drain because of large format tile then so be it, but folks need to know the cost of this drain as opposed to a center drain. great video btw, as usual.

I was real curious about the Kerdi line drain, you answered a lot of my questions. Great video Sal.

At 15:31 your kneeling on the tile. How long did you wait for it to dry? Assume over night, which is a bummer in that it delays things.

Hi Sal, should I expect a grout line against the drain and first row of tiles or does it butt up tight?tnx

Sounds like the compressor in your camera cuts back the audio making it harder for consistent audio.

Have you ever seen a linear drain at the shower doors edge? I wonder how much water ever travels past the drain?

Do you have any videos of this system in a curbless shower? Wondering how to get floor tile from the rest of the bathroom to meet up with the tile in the shower floor which is angled toward the drain? Thanks

i have a linear drain being installed on one side of the shower. the floor will be pitched to the drain. cutting the bottom row of wall tile will be a challenge. will it be ok to install the wall tile and then pouring the mortar in the shower liner to avoid the angle cuts?

What kind of cement or glue, do you use for the membrane?

question, doesn't this mean you will have long diagonal cuts on the wall tiles? I haven't installed one of these yet but I cant picture a way to have straight bottom cuts (level perimeter of shower floor) with these things.

Sal, what's your take on linear drains in general? Do you think that they require more maintenance than round drains, are they more prone to mildew/mold, any other issues we should know about before deciding on going linear?

I didn't find this video too helpful. A bunch of yacking at the beginning about unimportant stuff and then dead silence when installing the product. The images of installation jumped from mudded floor to what looked like non mudded floor. Waste of my time.
