10 Tips for Installing Subway Tile
After installing the floor tile in our guest bathroom, Finn and I were so excited to start the subway tile. Yes, we were tired and drained from all of the time spent on the floor…but subway tile certainly had to be easier than that marble floor…right?!
Well…sorta. It certainly wasn’t a super difficult installation. But, boy oh boy, was it time-consuming. And here’s the thing…we are both workhorses. I will not stop until I complete tasks and Finn and I were determined to get this baby done. But even if you’re working hard, it’s still pretty slow work.
And we had A LOT of ground to cover. We started in the shower and I seriously felt like I was climbing Mt. Everest. I laid the first 2 rows of tile, glanced up to the top of the wall, and felt like there was no way in hell we could ever “climb” to the top! With 10 foot ceilings in the bathroom, and a plan to go all the way up to the ceiling, right then and there we knew we were in for it.
However, we prevailed! It took us 2 weekends and multiple nights after work to get ‘er done, but we did it. And we’re obsessed with the bright & clean look we have going on in this space.
I’m not going to give you a step-by-step tutorial on how we hung our 3×6 white subway tile since I just shared the detailed process for the floor tile yesterday (and it’s very similar to that). Instead, I’ll share tips and tricks we learned along the way. And things I wish I would have known before I got started tiling our bathroom…
10 Tips for Installing Subway Tile
As a tiling newbie, I didn’t know that ledgers were used in tiling. In order to make sure all of your tile is level, you need to install a level piece of wood at the first row of tile. This ensures that all of the tile you install above that board will be straight.
I purchased inexpensive wood at Lowe’s (and brought the measurement of each wall in the room) and had it cut down to size right there. Then, I used a drill, screws, and level to get all of our ledgers in before we started tiling. Take the time to do this (& make sure they’re perfectly straight) before you install one piece of tile.
After the floor install, my hands were wrecked. The thinset dries out your skin like crazy and you really can’t expect to keep your hands clean when tiling. It’s impossible. For the subway tile, I bought dozens of disposable gloves. This was a lifesaver and my hands are finally feeling less scaley and gross!
Try a Tile Cutter
Our wet saw was the main workhorse for our floor tile, but we whipped out a tile cutter for the subway tile installation. This little tool is incredibly easy to use and it’s inexpensive…only $20! But my favorite part about it? We could use it at night without making a peep (unlike the wet saw, which shakes the entires building), so we could work on the space on weekday nights.
I will say, we did have to use the wet saw for super small cuts, curved cuts, and angled cuts. So we kept that out too. But for 85% of our cuts, the tile cutter worked like a dream.
Plan It Out
As much as we wanted to just get started tiling, we had to go in with a gameplan. And when I say gameplan, I mean math. Dun dun dun. Not my strong suit, but luckily that husband of mine is a math whiz! Essentially, you don’t want to have any tiny cuts on the corners (because it will make your life 10000x harder) so you need to plan your layout from the start. Pick a starting point (in our case, the main shower wall) and work your way out from there. Think about the ceiling and the floor too, you don’t want any slivers of tile on either end. Finn ended up planning ours out using Excel, but just a simple drawing and math will help!
Know your Spacing
You know how I just said that you need to make a plan? Well, we did do that. But we forgot to calculate one HUGE factor…the spacers. We were doing math based on our 3×6 inch tiles and the measurements of our walls. We totally forgot to include the 1/8″ spacers (rookie mistake) and that meant we had small cuts on our first big wall. Bummer (and major setback).
So, please account for your spacers! And another DUMB move I made? I didn’t account for the fact that our subway tile already had built in spacers. Yes. Most subway tile has grooves on the sides so you don’t need to use spacers at all because it’s an automatic 1/16″ grout line. I completely forgot about that and used 1/8″ spacers. This meant that we ended up with pretty wide grout lines. Which ended up being fine for the room, but it’s just something to keep in mind.
Protect your Floors
This may be an obvious tip, but please protect your floors! With our new marble floors installed, we didn’t want to take any chances of ruining them. We laid down cardboard that we cut to the room, and then we put rosin paper on top of that. We secured that down using painter’s tape. Be sure to protect everything in your room when tiling because the thinset will occasionally plop on the ground and you’ll be left with a mess!
Have a Plan for Edges
When ordering my tile, I didn’t realize that my regular 3×6 white subway tile didn’t come with a 3×6 bullnose piece (bullnose is the rounded edge). Instead, the only matching tile was a 2×6 tile. This ended up being fine, but we had to make a plan for how we would have it flow as both the top ledger and the side edges of the shower.
Finn and I laid out various scenarios before committing to anything and we ended up going with the look above.
Clean As You Go
The thinset is bound to ooze between your tiles a bit, so do your best to scrape it out as you go. If it dries, it’s a lot harder to get out before grouting. We also kept a sponge handy to wipe down tiles along the way to ensure that no thinset was drying on our pristine white tiles. Just be aware and wipe up after each tiling session.
Buy Extra Grout
Once all of the tile was up, we were ecstatic and I (naively) thought I could grout the wall in a couple hours. Boy, was I wrong. Because our grout lines were huge and we had so much ground to cover, it ended up taking me (& my mom who I recruited to help) about 8 hours to grout the walls. I bought two 10 lb bags of grout for the space (sanded in the color “Silverado”) and ended up having to run back to the store for 3 more! Stock up on grout and you can always return it if you end up having some leftover.
Finn and I weren’t prepared for how long the subway tile was going to take. I mean it’s just straight lines…right? Between all of the math, our high ceilings, and the large grout lines…we had our work cut out for us. But I’m happy we took our time and got ‘er done. What an amazing feeling to see it all up, grouted, and lookin’ good!
