I'm currently trying to set up the water line for my fridge, which hasn't had one before. I've successfully tested the ice maker using a 1/4" braided water line from my kitchen faucet. Now, I'm moving on to run the line into the basement and up through the floor behind the fridge. I've heard that while a 1/4" hole is the standard size for the line, a 3/8" hole might provide some extra room for easier maneuvering. I'm going to be drilling through tile using a diamond hole saw, and I just want to make sure I make the best choice with my hole size—should I stick with 1/4" or go ahead with 3/8"?

Just make sure you're measuring the outer diameter of the line, not just the inner! If your 1/4" line has an outer diameter closer to 1/2", going for a hole size like 5/8" might actually be the best move. This way, you won’t have to deal with tight spots.
I've been in a similar situation, and I opted for a larger hole too. Sometimes those connections can be tricky, and having a bit of leeway really helps to avoid any stress. Just make sure whatever you choose, it’s solid and won’t compromise your support structure.
Going with 3/8" sounds like a good plan! Once you drill the hole, you can always adjust the line a little if you need some extra wiggle room. Plus, since it’s going to be behind the fridge and hidden, a slightly larger hole isn’t going to be a problem at all. I'd definitely recommend using the bigger bit for more flexibility!
Yeah, I agree! The added space really won't hurt, and it'll save you some hassle in the long run!
Good tip! It’s always better to give yourself a bit more space, especially if it’s your first time drilling through that kind of material.
