Flawed

Contrary to what regular readers of my blog may believe this is not a page about my personality. This is a page with photos of improper tile installations. Please do not make the same mistakes. At the bottom of this page you will find information about, well, this page and how it came about.

If you have arrived at this page without searching for something akin to ’tile butchery’ please realize these are not correct installation procedures! The captions beneath the photos are my smart-ass remarks – they are not serious advice. :D It is simply how I tear out crap like this without my head exploding. I’m certain by now this is a very long page – don’t worry, it’ll be like a train wreck – you just can’t stop looking.

And I made ‘em big – real big. Hey, don’t complain! I’m the one that had to tear all this crap out. I did it so you can partake in the full glory of what happens when your contractor either doesn’t know better or just doesn’t care. If you’re warped like me you can click on each image for a very, very large version of each photo.

This is why I have Guedo. :guedo: Enjoy.

I’m a first time bathroom remodler. I have chipped out all of the old tile but there is still some mortar left on the floor. I was going to use a self leveler to make the floor fresh again. Question is: Is there a standard height that the toilet flange is suppose to be off the floor (before tile)?

Reply

Roger February 7, 2012 at 7:02 pm

Hey Frank,

Nope, the flange can sit right on the floor. If you need height you just use a thicker wax ring.

Great site (insite)
I have a 5′ x 12′ bathroom, 30″ x 8′ Suntouch mat, and Ditra.  Currently I have new 3/4″ Plywood on 16′ centers…

The new floor thickness works better if I don’t put hardi-board on the floor, i’m replacing 1/2″ subfloor and 3/4″ hardwood floor. That’s right, hardwood floor in the bathroom – Gotta love the 70′s.

Do I need 1/4″ hardiboard on top of the 3/4″ plywood floor for strength? …1/2″hardiboard…. thicker?

Thanks

Reply

Roger February 4, 2012 at 8:07 pm

Hey Tony,

Neither thickness will add any structural support to your floor. Backerboard has absolutely no significant structural strength at all. You really should have another layer of 3/8″ plywood over the 3/4″ layer, then the suntouch, ditra, tile. It *has* been done without the second layer of ply (not gonna say who did that…) but standards demand a minimum 1 1/8″ double layer of ply over your joists. You don’t need the backerboard at all, though. Ditra can go right to plywood.

Hi, Roger:
First of all, this website it great!  It’s very generous of you to take the time to answer all of these questions.  Thank you for this!
I recently had my kitchen remodeled and the grout along the counter top now has a very deep crack.  My contractor came in to “fix” it by using something that came out of a caulking gun.  The color didn’t match very well either.  He says cracking is normal when you turn on the heat…things contract and expand.  Is this B.S.?  Should I just call a tile expert and have them fix this?  Needless to say his fix didn’t work. 
Thanks for your time!

Roger January 20, 2012 at 8:31 pm

Hey Kristin,

Cracking CAN happen with heat if the installation is improperly grouted. It is not normal. Not sure what he filled the grout line with but even with cracking at the very least it should have been regrouted. The cracking is likely due either to movement or improper coverage. You should have a professional come in and take a look at it. Any tile guy worth his salt will be able to tell you what was done improperly and what needs to be done to fix it.

Roger,
Love the site, it’s awesome for the DYI’s in the world.  I have a question.  The man at Menard’s said I didn’t need to use a grout with Marble and you recommend that you do.
The question is, I want to use a 3″ cut to go around top of the floor as a “mop board” style trim.  The question is, does that go on before the floor tile or set on top of it?
First time Marble installer and this will definately be a challange.  But it’s that or nothing for we can’t afford to hire it done.  We’ve done ceramic tile and it turned out beautiful in the kitchen and bathroom.  So fingers crossed.  Thank you in advance and also want to say….Love your sense of humor!

Roger January 17, 2012 at 5:20 pm

Hi Diana,

You can set marble with 1/16″ grout – you WANT to do that – do NOT butt them. The base goes on after the floor is set. Install the floor then set the base on 1/16″ spacers so there will be a 1/16″ space between the floor and base. You want to silicone that gap rather than grout.

Hi Roger, I am about to lay tile in my bathroom.  The floor is only 5×3, Its a very small bathroom.  I have 7sq ft of heated floor mat to be put down.  The durock is already thinset to the floor.  I was wondering if I can Use the Lactice water proofing membrane over the durock and place the heated lines on top and tile over that or should I thinset the heated lines in and then put on the membrane and thentile over that. :bonk: Ive noticed you recommened ditra.. but for such a small area would either of these methods be ok?  I know you hear it alot but you really are an awesome guy for doing what you do on this site.  Thank you so much for everything you do.  I love the flow and humer of your page.

Roger January 15, 2012 at 11:37 am

Hey David,

Do you mean the ‘laticrete’ waterproofing membrane? You typed ‘lactice’ – never heard of it. :D If so, then either way would work. for best optimization of the membrane it would be best to float over the heating element with thinset or SLC, let that cure, then use the membrane and tile over that. The liquid topical membranes like redgard, hydroban, hydrobarrier, etc., also have crack-suppression properties which assist in compensating for any substrate movement beneath your tile. This is only true when installed directly beneath the tile rather than beneath the heating wires. So doing it over the wire would best utilize the products in your case.

David January 15, 2012 at 12:05 pm

You are correct it is laticrete haha.  Thanks for such a quick response .  Also Im pretty sure your positin on this is thinset…but two guys at lowes were very convincing.  For applying tile to the shower walls and floor, They had me get the big pink bucket of laticrete mastic.  I also bought a grey and white bag of Laticrete multipurpose white thinset just in case.  Should one be used on the walls and one on the floor?  I read the whole page you have on tile adhesive.  Im just worried i may have misread something. Thank you again..Im getting ready to start with your response.

Roger January 15, 2012 at 12:18 pm

Use the powdered thinset in the bag you mix with water to install all your tile in the bathroom. Take the bucket of mastic back and throw it at the uneducated employees attempting to sell you incorrect products for your shower tile installation – and give ‘em my website address (I’ll be nice). Or keep it and tile your kitchen backsplash and fireplace. :D Which color of thinset to use is determined only by the color of your tile. If you are using a lighter tile or natural stone use the white, darker colors get gray.

hello , like your site i have been in construction for thirty years. I install cabinets,laminate and trim so i have been around the tile guys for many years. That being said, i have added tile to my arsenal. im doing tile slate shower with 1×2 mosaic mix in with 4×4 field . the 1×2 mosaics came on a webbing pre gaped with grout lines between 1/16 to 1/8,  but my 4×4′s are set at 1/4 inch. Should i buy un-sanded for the mosaics or just use the sanded for all…or if i use un-sanded will it match the sanded, or mix up my sanded more wet to get in smaller grout lines,
“Buy the way my mosaics were falling off there webbing what a pain to install…lol…omg”

Roger January 14, 2012 at 12:58 am

Hey Dave,

You can use sanded for all of it – no need to mix it thinner either – that weakens the grout and may lead to efflorescence. You can get sanded and unsanded in the same color and, although the same color, they will look slightly different due to the sand.

Hello Dave. Can I impose on a “tile” website?  Roger has already helped me with my tile questions – we are filing a complaint with the Registar of Contractors in AZ against the G.C.  That includes the tile sub, AC sub and roofing…etc
Can you tell me, since you are a cabinet expert, what kind of kitchen cabinet is the absolute cheapest, dirt cheapest, plastic, tin sounding cabinets can a licensed contractor buy?   I live in AZ.  There are lots of places that advertise cheap cabinets but the ones installed in my home are so cheap when the sink leaked the cabinet floor under the pipes pealed from what ever the cabinet was made from.  It’s like wall paper was glued to a surface to make a kitchen cabinet.   Where does a licensed contractor buy or what kind of place sells commercial grade cheapest cabinets?  I am not looking for the name of a business just what type of business would he have gone to for purchase?  Any ideas would help me.  Thanks.

Roger,

I’ve taken on the daunting task of providing my wife the bathroom lifestyle to which she (wants to be) accustomed.  That said, I ran across your site doing research.  The 0369 in me requires precise planning before conducting any operation and your site is an awesome resource. Especially enjoyed the dinked up tile jobs on this page. Great site and outstanding recommendations.  I’ll be refering to this often during the next 30 days. Semper Fi.

One question more, actually two questions,  which I hope (and I’ll bet you hope, too) will be my last.  We’re working on the sandstone project in the bathroom, and have decided (with your help) to use Spectralock epoxy grout.  This sandstone is not totally level, and it’s, well, sandy.  We’re planning to use epoxy grout, because we’re afraid that regular grout will require so much washing that the grout colors will change slightly (or a lot).  However, we’re even more afraid that the epoxy grout won’t come out of the little bumps and ridges in the sandstone leaving us with an unattractive mess. So, questions #1:  are we better off with a grout bag (keeping in mind that neither of us has won a cake-decorating award in the last, say, 100 years, or should we just apply the grout the regular way and wash the h%$^ out of it.  That’s question 1, and we’ll do whatever you say (how’s that for a power position?)  Question #2:  We used an enhancer and sealer on the sandstone before installation, and the color is too dark.  Once we’re done grouting it, is there a product that will remove the sealer, so we can put a lighter sealer on it.  (guessing the answer is “no” on that one, and we’ll have to learn to love our small, dark bathroom that has taken us hundreds of hours to finish)  That’s the home improvement biz :)  
Thanks again for all your advice, the bathroom is turning out beautifully, and looks custom and upscale.

Roger December 27, 2011 at 7:32 pm

Hi Ann,

Don’t even bother with the grout bag – way more trouble than what they’re worth. Your best bet would be to get some grout release. It’s a lot like sealer but doesn’t fully cure on the surface, washes off with water when you wash the grout, and prevents grout from sticking to the surface of the stone.

There is no product which will lighten the enhancing aspects of the sealer. Sorry. :D

Roger,
In the military, we’d call stuff like this FUBAR.  (The cleaned-up definition is Fouled Up Beyond All Recognition.)  In military aviation, we’d call it Buffoonery.

Thanks for all you’ve done on this site.  Merry Christmas and Happy New Year.

I knew there was something about your style of humor and the manner in which you educate the masses… My son was the youngest marine in his group at boot camp.  17.  He is now a SS and is stationed in Virginia with all the working spies…The kind of job where he says “mom I can’t answer that…”  I ask but he just smiles and shakes his head no.  His father was a Master Chief in the Navy – they have very animated conversations…
 
The photos of the bad, bad, really bad tile work are amazing and very educational for me. I now know some of the correct terminology and understand better the mess in my own house. I can see things in my house that look exactly like some of the photos.  Especially concerning the cracked grout, cut work around door jambs, not enough coverage. One in particular #37 looks like you took the photo in my home – I need to read about substrate.  Thanks.
