Shower Tile Installation Tools (QUICK TIPS)

5 Materials
Today you’ll get five tool recommendations that will make shower tile installation easier.
I got these from my Bathroom Repair Tutor co-founder Steve.
If you’re new to HRT, Steve is a 14 year veteran of bathroom remodeling.
He’s awesome at tile work and does high-end bathroom installations.
So you’d better listen when he talks…just kidding, but seriously, I listen!!!
Here’s a story: years ago I did my first bathroom remodel.
All was good during the first day.
But then I ran into a wonky shower window and made some goofy tile cuts.
To this day I cringe at some of the tile work in that bathroom.
I’m pretty sure the project would have been better had I used the tools in today’s tutorial.
Here’s the supply list you need
Laser Level
Laser Jamb
Horseshoe Shims
Carpet Knife
Well, I guess that spilled the beans.
But why do you need these tools?
I’ll explain…
Here’s the Bosch laser level Steve recommends.

It’s not cheap at $129 (the Bosch model number is GLL 3-15).

But let me tell you, it’ll make your shower tile look 100% better than if you eyed it up.

Plus, it won’t smudge…unlike a pencil mark or chalk-line.

The Bosch model here shoots both a vertical and horizontal laser across the wall.
So you can line up the vertical tile joints with each other as you move across the shower wall.

But how do you keep the laser still while working?
The first time I saw Steve use this tool I was like ‘what the heck is that?’.

After he explained how to use the Laser Jamb I was super impressed.

What a cool idea.

Basically you attach the laser level to the jamb and place it anywhere in the room.

How does it work?

Simple, it has two feet.
One is on the floor and the other on the ceiling. It uses pressure to hold itself in place.

Then you can slide the laser up and down the metal framing.

Pretty awesome!!

The picture above could be better but the bathroom was small, like Willy Wonka small (whatever that means).

What if you have thin-set that oozes in between the grout joints?

How can you remove it?
After editing hours and hours of tiling videos for Bathroom Repair Tutor one thing became clear: the carpet knife is a must.

Steve definitely convinced me I need to use one.

Carpet knives are only a few bucks and are great at removing thin-set from grout joints.

BUT make sure you’re careful…carpet knives are super sharp.

So it’s not a bad idea to dull them either with a file or by rubbing them on a sold surface like wood.

Be very careful using the carpet knife as you don’t want to pierce the waterproofing membrane behind the tile.
Also, when you use a carpet knife to remove excess thin-set it’s not a bad idea to have a damp sponge nearby.

You can wipe the thin-set on the sponge as you inspect each grout joint.

As a side note, you’ll want a separate bucket of water and a sponge close by while tiling anyway.

Because you’ll want to continually remove the thin-set from tiles as you set them on the shower surround.

How do you get perfect grout joints in the first place?
Attention to detail is everything when tiling and Tuscan SeamClips help you stay on track.

These little clips slide behind the tiles.

And when you use them they help clamp the tile to the wall.

Furthermore, the SeamClips compress the tile into the thin-set and create a smooth transition from tile to tile…which eliminates tile lippage.

Lippage is simply when two adjacent tiles are even.

Position SeamClips 2-3 inches from the edge of the tile and every 6 to 10 inches along the tile.

You’ll need to know the thickness of your tile before purchasing SeamClips.

They come in Red, White or Blue.

Each color represents a different size SeamClip. We used Red SeamClips in this tutorial because the porcelain tiles were 3/8″ thick.

Some people say you don’t need a leveling system like SeamClips if you’re a good tile setter.

But honestly, wouldn’t you want to give yourself every advantage when tiling?

Plus how often are you going to tile your shower or floor? Once every 20-30 years.

Personally I find them to be very useful but you can decide for yourself.

Now, SeamClips are great at leveling tiles but they’re only 1/32″ wide.

Therefore you’ll need a spacer for properly sized grout joints.
Horseshoe shims are great for this.

They’re made from plastic and come in different thicknesses.

The horseshoe shims are in between the SeamClips in the picture.

Placing them at tile transitions, for example where three tiles meet, helps keep grout joints nice and even.

We recommend getting 1/16″ horseshoe shims.

That way you can use them in 1/16″ increments to get the grout joint you need or to shim tiles up off the tub.

You can buy horseshoe shims online or at your local tile store.

I’d recommend calling your local tile store first though if you’re not an Amazon Prime member…shipping can be crazy on these!!

    Too much info for the DIY! A regular level is prefect for the DIY and something they probably have. Regular tile spacers work just as good. A popsicle/craft stick works great in removing excess thinset. DIY's want to save money not spend it on some thing they may only use once. That's why they do the jobs themselves and they come out looking great with basic tools.

    Hey nice DIY. New here. I see you used normal cross line one here. Can you tell, should i go with just normal cross line one or Laser levels dedicated for tiling ? Just like Bosch GTL2 & Bosch GTL3. I just want a simpler solution.
