DIY How to Build and Waterproof Shower Curb on a Concrete Floor

[@familyguy5081]

I see a ton of videos of guys discouraging actually screwing the inside of the shower liner regardless of how many layers of waterproofing you use. I appreciate taking the time to teach.

[@simonproatl]

They just don't have enough experience and lack of common sense. The most important is to waterproof and install the inside cement board above the shower pan. If you don't have direct contact with the pan and everything is waterproofed then you don't have any problems. Most contractor install that inside piece of cement board all the way to the rubber liner and then they build a pan (this will cause problems) Cement boars will absorb moisture if summered in the pan especially if there is no pre slope. I replaced over 200 showers and some would hold 1" of water in them (especially the ones without a preslope and clogged weep holes)

You make that look real easy my friend. We will be installing a walk in shower soon and you taught me alot here. Thank you for taking the time to make this video. It look great.

[@simonproatl]

I'm glad that it was helpful. Good luck with the project.

[@universalroads8176]

This is the most informative video I’ve seen on tiling. You explaining the reason why you do it that way will help people from skipping steps and making mistakes.

[@simonproatl]

Small mistakes can ruin the whole thing and it's so expensive to fix it. I'm glad that my video was helpful.

[@doraabigailmorales4639]

This video is so detailed and love how you actually are doing an amazing job water proofing .

Glad it was helpful.

It looks like this video went from concrete right to an already installed membrane of some kind before finishing the 2x4 barrier. Later you put down the rubber barrier. What did you install there with the blue, woven material prior to putting on the 2x4 barrier out front? Did some other searching online and it looks like you have to build your base shower bed before following this video. The base "pan" is created with concrete and waterproof membrane, hen pan dirt is used to slope the pan into the drain.

[@simonproatl]

1. Install shower drain and valve . 2. Install shower curb (2x4) 3. Build pre-sloped mortar pan that is waterproofed with waterproofing membrane and fiberglass mash. 4. Install shower pan liner 5. Build mortar shower pan 6. Waterproof shower curb 7. Install shower walls cement boards and waterproofing. 8. Install and grout shower floor tiles 9. Install shower curb tiles 10. Install shower wall tiles

[@simonproatl]

@@G3MAProperties I build pre sloped pan after nailing first 2x4 to the floor.

[@vinhgolf]

great video. just to confirm that you cut the outside cement board piece, is it 1/4" higher ? if it is true, the top piece, cement board will have a slope, right?

[@simonproatl]

Yes, correct

[@vinhgolf]

@@simonproatl do you recommend using the same method over the plywood floor ? Or using something else ?

[@simonproatl]

Same method will work. Instead concrete nails you can use 3" screws to install first 2x4 to a plywood. @@vinhgolf

[@vinhgolf]

got it. thank you. @@simonproatl

[@tylershank1870]

Shouldn’t you allow the mapei to dry before spreading thinset?

[@comancheclub3449]

Last shower i did, i did not use any rubber liner. I built my curb (wood, cement board, then thinset and mesh to fill out, smooth and make uniform) and preslope. After which i coated the curb and pan with Red guard 3 times (same thing as aqua defense except Red) After that i put my final slope, coated everything in RG again and then tiled over that. Hopefully that made sense. This was all done over a concrete slab.

[@thelog86]

That's going to fail, you have to have a shower pan, I hope it's located where there is nothing below that shower

[@comancheclub3449]

@@thelog86 Why would it fail? Yes, it is on a slab.

[@nghiaho535]

I did the same steps as your on the second floor 7-8 years ago and did not have any leak. Last year I have to do some ceiling repair of the first floor near the shower and found that the subfloor below the entire shower is bone dry. In my conclusion, waterproofing Red Guard or similar part works as well as the liner.

[@simonproatl]

I guess you haven't watch my other videos. I guaranteed my work for 5 years. I did this for 20 and it never failed. Thanks for watching

[@simonproatl]

It won't fail. Average person watches few minutes of the video and the make some comets that don't make any sense.

[@stevetalin6489]

Looks like you applied the thinset over the waterproofing membrane before it dried then painted another coat of waterproofing membrane over the thinset before it dried. It would seem that once the outer layer dries it will encapsulate the wet thinset and never fully harden. What do you think.

[@simonproatl]

It's better to wait till it dries. Waterproofing over wet thinset dries very well. Never had any problems.

[@HookedonHD]

I missed how you made that slope at the end.

[@simonproatl]

By installing cement board 1/4" higher.

[@HookedonHD]

@@simonproatl Oh okay, I missed that.

[@cliff1953]

Nice work

[@simonproatl]

Thanks

How is this curb doing you put screws on the curb

[@simonproatl]

It will last for many years. Never fails if you do it right. :)

[@jasonmurphy4501]

😂😂😂😂😂😂

[@mikeknight1071]

ur the best @simonproatl , quick question, what if i want to install a shower door on the curb would i still angle everything towards the pan? or would i want the curb to be flat and level?

[@simonproatl]

When you install tiles you have to make sure that they slope toward the pan. 1/4" slope is enough. Curb and shower walls must be level and square.

[@AQUARIUMFREAK123]

Would this OATEY pan liner and glue be AQUARIUM SAFE ? can i make an aquarium seal out of these materials seen here ?

[@simonproatl]

Pond liner is more flexible.

[@vinhgolf]

i just saw the video again and i noticed you used some type of membrane to cover the curve and around the shower area . what type is it?

[@simonproatl]

Mapei - Aquadefense - Waterproofing membrane

[@eyeye_agent]

@@simonproatlis there a video laying out the mebrane?

[@rexburris416]

Probably because he ran screws through the front of the pan membrane ruining the waterproofing.

Only if you make a swimming pool out of you shower :)@@rexburris416

How do you make a curbless shower on a concrete slab

[@simonproatl]

I don't. Curb is better :)

[@1999C2996]

That's pressure treated wood??

[@simonproatl]

yes

[@simonproatl]

@@RawTakes You have to use pressure treated wood on concrete. It's code.

[@Whenbsjskgbsjsbn]

Exactly what I needed unfortunately the videos Jumps from one step to another and confusing for a DIYer. why not upload the whole video if your intended audience is DIY.

[@simonproatl]

Thanks for great advice. My goal is to do smaller videos first then one long one with more details. Thanks for watching

[@martingates6501]

Everything it's ok but you waste a lot of time with the level, place the level far away from you

[@simonproatl]

Square and level are two must important tools!
