White on white grout/tile will hide rookie mistakes. And frankly that's not too bad.
Staining the grout to match the tile should hide the imperfections, adding a bath mat to the room will break up the straight lines. I'd try doing this, and if you still hate it you can rip and redo. Worth trying to salvage it first, it looks like a nice tile.
partim Paint them with some kind of paint that you will be able to wash off the tile, in a color that is similar to the other tiles. Go to Michael's and see what they have in the children's section. Watercolor paints should wash off ceramic tile. Once you have appliances on the counter etc, you'll hardly notice them.
Use trim to mask uneven edges. Trims cover gaps and create clean lines. Choose from metal, PVC, or wood trims, depending on your tile color and style. If one edge is higher, smooth it gently with a tile file.
No gapping between the tiles and walls
To inspect for gaps, place a straight edge against the tile and wall, and look for any spaces in between both areas. A properly done installation will not have any gaps. Additionally, corner and side wall cuts should be clean.
Sanded grout is also adept at hiding minor imperfections in the tile installation. However, the textured surface can be more challenging to clean and may trap dirt and grime. As the name suggests, unsanded grout does not contain any sand particles.
While grout can help to minimise the appearance of unevenly installed tiles, it cannot completely hide them. If the tiles are significantly uneven or have large gaps between them, using the same colour grout may make the problem less noticeable, but it will not completely conceal it.
1 depends on the type of tile, but ranges from approximately 1/32" to 3/32". So 1/32" warpage plus 1/32" equals 1/16" allowable warpage for most tiles with some exceptions.
In some cases, it's possible to have tiles custom-made to match your existing ones: Tile Replication Services: There are companies that specialize in creating custom tiles. Provide them with a sample or detailed photographs for the best results.
It simply involves applying mortar as normal to the substrate, but then also applying mortar to the back of the tiles. Extra mortar is applied to areas that need it – either areas with dips in, or areas with thinner tiles. This will even out the surface, creating a perfectly flat tiled surface.
Using caulk, trim tile pieces and edging are three of the most popular and effective ways to finish tile edges. Caulking is the cheapest and easiest method for finishing tile edges.
– Apply the Grout: Use a grout float held at a 30 – 45-degree angle to press the grout diagonally across the gaps between the tiles. Ensure all gaps are completely filled. Work in small sections to prevent the grout from drying prematurely.
Finally, if you've already laid your tiles and are wondering how to hide tile lippage, you can use grout to mask the height difference. This has the added benefits of absorbing tile movements when they expand and prevents visible lippage from getting worse.
The 33% offset reverse pattern creates a simple and consistent pattern that can minimize lippage. Rather than having the two low points adjacent to the high point as in a 50% offset, the tile in row one is moved to the one third point (33%) of the tile in row two.
Aim for Flat, Not Perfectly Level – Remember, you don't need to make your floor perfectly level. Often, that's just not realistic, especially in old homes.
Now when you go with a black tile and a white grout you are going to see that visually (like with white tile and black grout) things start looking a bit busier and you do make out the shapes of the tiles more so than you would if it was all tonal. Still, a very pretty look which we love.
If the lippage isn't too terrible and only affects a small number of tiles, you might be able to grind the edge down to make it even—or at least appear even—using a hand sander or an angle grinder (or, in a pinch, low-grit sandpaper).
Another major benefit of tan and beige grout is that it doesn't show imperfections, dirt, or grime the way pure white does. These colors have low grout maintenance. Use them in kitchens and bathrooms.
It's important to remember that black grout can be very messy and difficult to clean up. Grout is similar to kinetic sand in texture—it's gritty, and it can go everywhere, even with the most experienced professional. And because there's such a contrast between the tile and grout color-wise, any mistake will stand out.
Quarter round, cove or glass bead profiles would all work. Attach any of the above with construction adhesive, then seal the edges with silicone caulk. Tape your lines with painters tape before caulking, run bead, smooth, allow to set for 3-5 minutes and then pull the tape.
