Everything I normally write is about building your brand new awesome shower. However, to do that you must first remove the old, outdated, non-awesome shower. There are several ways to do this, I’m gonna show you the easiest.
A lot of people will go in and chip every tile off the wall (don’t laugh, they do it…), then remove the drywall (or what’s left of it) to get down to the studs in order to build the new stuff. You don’t need to do that. It’s time-consuming, messy and will give you a fairly crappy attitude about the project right from the get-go. (Did I just type ‘get-go’??? I need a beer…)
Most existing tiled showers being torn out are ‘builder’s grade’ showers, that means 4×4 or 6×6 tiles with a bullnose tile, normally 2″ wide, along the edges. Chipping each tile off the wall will waste an entire day. So you’re going to remove entire portions of the wall at a time.
The first thing you want to do is chip off the bullnose, or little rounded pieces, along the edges (and top, if you’re not going to the ceiling) of the shower. If you notice in the photo to the right I’ve already done this. [continue reading…]
One of the most frequent questions I get asked is ‘What size and type of trowel should I use for…?’ The proper answer to that is ‘whichever trowel gives you the proper coverage for your particular installation’.
So there really isn’t one perfect answer to that question, a lot of factors are involved. But I’ll try to help you out.
Proper thinset coverage
The first thing you need to know is what constitutes proper coverage.As stated in ANSI A108.5 3.3.2 for installation of tile on floors; “Average uniform contact area shall not be less than 80% except on exterior or shower installations where contact area shall be 95% when no less than three tiles or tile assemblies are removed for inspection. The 80% or 95% coverage shall be sufficiently distributed to give full support to the tile with particular attention to this support under all corners of the tile.”
When you build a shower you will eventually need to make some holes in it – it’s just part of the overall process. You’ll need to install frames or hinges for your shower doors, grab bars, shower curtain rods, a picture of your pet iguana – whatever. The problem is that now you have that completely waterproof shower you really don’t want to go poking holes into the waterproofing.
No matter which waterproofing method you’ve used any fastener penetrations will have to punch a hole into it. You want to make sure you install your screws properly in order to maintain the integrity of the waterproofing. You don’t want to ruin all your hard work because you need to drive a screw through it!
The first thing you need to do is mark the exact locations of your screw holes. Most things like grab bars come with little templates you can hold up and get exact placement. With shower door frames and stuff like that you can hold up the frame piece and mark the correct location.
In my previous post I showed you how to make a niche for your shower out of Kerdi-board. If you haven’t read that you probably should. It’s gonna be really difficult to install a Kerdi-board niche if you don’t have one.
When I install shower niches I prefer for the edge of the niche to be lined up with the grout lines in the tile installation. This way it looks like it belongs there rather than looking like something that was an afterthought (I HATE that…). So it requires planning.
When I build my niche I make it the same size as the tile I’m installing (or a multiple of those tiles, like two tiles high by one tile wide). This will be the INSIDE dimension of your niche when you build it. So again – more planning.
If you want a little something unusual in your shower installation you can always put glass mosaics in the back of your niche. It looks cool. The problem, however, is that when you buy a sheet of mosaic tile it may be one square foot of tile, but it has all those funny mismatched edges that aren’t straight. Every row of glass is offset.
This is done in order to not have grout lines in the installation line up (it’s supposed to look random) and to allow each sheet to interlock with the one next to it. In other words the left side of the sheet interlocks with the right side of the one next to it.
But if you only need one or two square sheets, like for the back of a niche, it won’t really fit in there in the stock sheet form. A reader asked me a while back if she had to order three or four of those sheets to do her one foot by two foot niche. Like the one on the right there.
(You can click on any of the photos for a larger version.)
Because the sheet is actually more than one foot wide (each row is offset) but there is no way you can cut one or both sides off and end up with a 12″ wide mosaic she thought she would need to order more to fill in the missing pieces. You actually only need two pieces, it fills itself in.
I’ve finally gone and done something worthwhile! Well, that’s a matter of opinion, I guess, namely mine. I have written complete manuals on properly building and waterproofing your shower utilizing the different waterproofing methods.
Each manual describes a specific method so you don’t get bogged down with a bunch of information you don’t need for your chosen project. Not sure which method you want? Not sure which methods are available? Didn’t know there were different methods? Start with the free manual here: Shower Waterproofing Manual. That will help you decide which one you want to use based on time, skill and cost.
Once you figure that out you can get the manual that is specific to your particular project. Although these are all mostly completed it’s a whole process to get them ready for you guys. It’s difficult to describe but it includes half a watermelon, platypus eyelashes and a full moon – weird, right? Let’s just say I’ve been writing the damn things for close to two years – it’s not a short process.
Anyway, I do have two of them all finished up, uploaded and ready for you to devour!
I have the complete shower manual utilizing the traditional waterproofing method for walls and floors. This will walk you through the entire process for complete shower floor and wall building and waterproofing. If you are going to have a tiled shower floor and walls and need to construct the entire thing – this is the one you need. You can get it here: Complete traditional shower waterproofing method (Price goes up next week!)
And I have the manual using the traditional method for just your shower walls. If you already have a tub or pre-formed base (like acrylic or Swanstone) this is the one you need. You can get it here: Traditional waterproofing for your shower walls
You can always just click the yellow highlighted ‘Library’ tab at the top to see what’s currently available. If you have any questions just feel free to ask them in any of the comment sections on the site. I always answer them – I’m just super cool like that. I will add the new manuals to the library section as I finish them up.
I get a LOT of questions from my readers about basic shower construction. I understand that my readers don’t consider this stuff basic and there’s no problem with that. The problem is that I end up answering the same questions over and over and over… So, to save what very little is left of my sanity (which is a number roughly equivalent to absolute zero) I will cover some basic things here so I can simply reply ‘read this’.
If you’ve been channeled to this page by one of my smart-ass comments please take no offense to it, I’m here to help. Please understand that I currently have over 12,000 comments (questions) on this site (seriously) which I’ve answered – every one of them. I’m just trying to make your life (mine) easier. I will continue to answer every question I’m asked, I’m just super cool like that. If, after reading through this, you still have questions feel free to ask them in the comments below.
You can also download my shower waterproofing manual which should answer a lot of questions and cover basic techniques and methods you may be confused about. Go ahead, it’s free. So without further ado (doesn’t even look like a word, does it?) let’s get on with it. (For all my readers who feel the need to correct me: I KNOW it’s actually ‘adieu’ – I was being facetious. Thanks. )
Another request from one of my readers, this time concerning weep holes. As you may know I answer every question I’m asked here on my site when I sober up get home from work. I have tried to explain in the comments section several times where to create weep holes in a tub or shower (acrylic base) tile installation and now realize it’s a difficult thing to do with words.
So when Kurt asked me to clarify exactly where they go a stroke of genius hit me! (Yeah, I’m slow sometimes) I have pictures. Well, not exactly pictures of the weep holes themselves, but I can at least let you know where they are.
When you have a tub which does not have specific spaces for a weep hole you need to ‘create’ them in your caulk line. Let me back up here a second and explain what weep holes are and why you need them.
Michael has recently pointed out (a bit more eloquently than I would have) that I have indeed been a lazy bastard and have not yet written this post. Apparently people actually want to know how to do stuff I do – weird, right? So here you go – making your ceiling shiny.
The main problem people have with tiling a ceiling is getting the tile to stay where they put it. Believe me, I’ve had more than one tile fall on my noggin before I figured out what works. Since I’m relatively certain you aren’t very interested in what doesn’t work I’ll tell you what does, it saves headaches – literally.
You do not need a $75 bag of non-sag thinset to tile a ceiling. Non-sag thinset is basically just thinset that is sticky – it’s great stuff! It’s also expensive stuff. You can accomplish the same with the $15 bag of regular modified thinset.
Before you start hanging head-bashers (ceiling tile) you should, as always, have the substrate properly prepared. They do not always need to be waterproof. It’s a good idea and never hurts, but it isn’t always necessary. The photos of the shower I have here was in a small bathroom with limited ventilation so I waterproofed the ceiling as well.
Once your niche space is waterproofed you can do just about anything you want with it as far as design is concerned. That is not to say you should cut out and build the niche space then decide what to do with it – you need to know what you’re going to do with it before you start.
Run tile up to niche sides
The niche I’m using for these posts is simply an empty shelf in the wall. There are no additional shelves or design elements incorporated into it. We’ll get to that in a bit. This one is very simple, though. We will just place one full tile in the back and install bullnose pieces on the sides.
You can start by running the remainder of the wall tile up to and around the bottom of the niche and the sides. (I did not do both sides of my niche yet because of the distance to the back wall – you should.) Do not run the tile over the top of the niche yet.
If you’ve planned it correctly your grout lines should be lined up with the top and bottom of the niche like they are in the photo. Depending on your layout, design, or framing this is not always possible but if you can line them up it looks better most of the time.
Well now we’re ready to waterproof your curb. If you have reached this post before reading the previous two, start with How to build a shower floor from the beginning. Now that you’re ready to get the curb cut and waterproofed lets get it done.
And yes, I know my pictures suck – I’m a tile guy for cryin’ out loud, not a professional photographer. Until you try to balance a liner, a razor knife, a margin trowel, and a camera while trying to take a photo don’t give me any crap about it. Oh, and you can click on any of the images for a full-size version – partake in the full glory of how much my photography sucks.
We need to start by finding the inside lower corner of your shower pan and making certain that the liner is pressed firmly against it. Then follow it up the corner of the curb and wall to the top inside corner of your curb. This is the spot at which you will start the cut in your liner.
