Love your floor.

The grout that is there is sufficient, I think. The bathroom is very cute. Have you looked into prettier plumbing for under the sink?

Thanks, guys! I had prettier plumbing for under the sink but due to a miscommunication it wasn't installed :(

just swap it out yourself, shouldn't be that difficult

That floor is exactly what I’m looking to do with mine! Tell me how/where pleeassse!!

Cut your paintable black caulk tube tip very small. Dispense a small bead between the wall and tile, spray it with a gentle Windex mist, spit on your finger and wipe up the overspray immediately. See if you like the look before continuing.

Thanks, Joseph! I'll do that.

@shayr, there are two ways to get a mosaic floor with the hex tile:

1. The best way is to design one on the Daltile website, then order it from a local supplier. It's not that expensive - about $13 a square foot. I did not do that, because Daltile only makes hex mosaics in unglazed tile, which seemed like a bad idea in a bathroom used by two boys.

2. I bought a black and white pattern, pulled a bunch of the white tiles off, and replaced them with blue hex tiles purchased separately (merola tile). I used Weldbond to attach the blue tiles to the mesh backing. It was a bit tedious, and also the blue tiles are thinner than the white and black tiles, although they're from the same company, so the end result is a bit wavy.

Good luck!

Did you incorporate a tiling layout error in your floor? Here is a thread that I started some years back now:

I suggest that you get one of those 'push & seal' pop-up drains for the sink. Will eliminate a lot of that hardware beneath. I installed a cheap Phister one in the master bath are few years ago. Worked so well that I replaced the old style lever operated one in the main floor powder room this past spring. They work really slick, don't leak and are easy to clean out.

I left the lever thing on the faucet body because I didn't want an uncovered hole. Just disconnected it.

No intentional errors, although that's a neat idea. Plenty of unintentional errors, though!

@rmiriam thankyou so much! That is exactly how I was thinking I would have to do it, I’m good with tedious if I get the same beautiful results as you!

I would only use silicone... not siliconized acrylic because that starts looking like crap before a year is even up and you'll wish you hadn't caulked at all.
You can also use painters tape to get a nice, crisp caulk line... peel it up as soon as you finish smoothing the caulk out.

What I used in my bathroom at the edges of a clean long edge of modern flat tile was sanded caulk. It was something I got at Lowes, I think it was Mapei's caulk. It has a very even look and looks a bit like the thin set in texture. In my other bathroom I used color matched silicon Laticrete caulk. Both are working. I would not use clear silicone.

You would have to put a paintable silicone. The reason you use silicone and not grout is when the building shifts or with humidity, the grout will crack so you will have to keep repairing it. Silicone is water resistant and flexible.

Silicone caulk that matches grout colors are available.

I love the combination of tile you put together, Miriam. I might just have to steal that for my laundry room!

I have to try the daltile floor maker thing - didn’t know it existed. There are two yucky bathrooms in my house that are ripe for renovation.
