Waht do you mean break them? You will need to take off the small edge tiles on the floor very carefully . Once you have them removed you have abteer idea of how they were attached clan up all the redisdue of the floor then meaure and cut the new tiles to fit allowing for the same grout lines adhere with the same material used on the old ones let dry for a couple of days then grout and install new vanity.. You are very lucky to find the matching tile

I meant I need to remove the cut tiles. And potentially add plywood to build it up before mortar then add a DITRA layer for waterproofing, then add tiles and then grout. So you suggest waiting a few days?

You don’t really need waterproofing or any of that stuff under a vanity. The waterproofing is useless… you have unplumbed holes through the floor, any water is going to get to the wood through those holes anyway.

You just need to build up the area so the new tiles are even with the old tiles. It is probably easiest to match whatever is already there, but not necessary.

You probably don’t even have to tile it all. Just replace the partial row with a full tile on the front and exposed side and you will be fine. No one is going to see that back 6” anyway.

Doesn't look like from the picture there is any backerboard under the existing tile. Looks like they just put down thinset directly to the underfloor and tiled. To make it look nice, you would have to take out those partial pieces with a saw of some sort, and put new tile in. Looks like you won't put in anything except thinset underneath or the height will be different. Maybe you don't if those lines are covered up by the new vanity. Tile around the plumbing lines.

Why......................

Are you saving this floor in a bath remodel?

What is the vanity? What is the bath plan?

Where is the vanity picture.

If you own the tile, you "break" the old at the grout lines.

Fyi

You knew you'd remove the vanity in ANY case? A little drill through the bottom of sink cabinet would have eliminated the "surprise, " which actually isn't that. The builder tiles to the shimmed up vanity and puts the toe kick on in building process..... especially decades ago. Rarely is there tile beneath, just as there is none under your kitchen island.

I'd take all the dated tile off the floor and redo the entire bath floor in something else, unless a reason that's impossible

Show the whole bath, please.

It might be easier to redo the whole floor than it would be to patch, and it might not be that much more expensive. You are having to pull the baseboard to run new, and do some other patching and painting in either case.

People are bananas. The OP is replacing a vanity… not remodeling a bathroom. Let’s not increase the scope and budget a hundred fold just because you think it would look a bit better.

The OP needs a hammer, chisel, and $35 in tiling supplies and tools. Chisel the tiles out from their cut side. Clean out the old mortar and grout. Build up floor if needed. Lay four tiles and install the new vanity. Later on if the OP wants to redo the entire bath the vanity can be removed and they are out like $40.

ETA: In what world does running new baseboards and patching and painting = the cost of demoing and replacing a bathroom floor?

If you’re handy and open to watching lots of Youtube videos - you can Diy that (tile saws are easy to rent) - it’s likely too small of a job for a tile pro, but they would likely be open to doing the whole bath if you needed help

You can lipstick anything: ) We don't see the whole bath, do we? No.

Patches frequently look like patches. It might be easy enough to cut those four tiles out, get the new tiles set level with the others, and get a good grout match and have it all look nice and seamless under the new vanity, and it might not.

Running new base and patching and painting has nothing to do with replacing six tiles specifically, it will have to be done in either case. Which is why I said that. But if you are removing base from the entire room rather than patching that in, too, it's an opportunity to decide whether it might be almost as easy to replace the whole floor if you have the opportunity.

We all know you could do an exceptional job at replacing these 6 tiles bry11 because you are an exceptional polymath who excels at whatever you put your mind to, apparently. But just because someone doesn't agree with every golden piece of advice that trickles from your mouth does not make everyone who doesn't crazy.

It's a dated floor in a muddy tone.. I see gray wall, probably new. For all we know, it's 40 odd sq, feet to replace it all, UNLESS it's o.o.t.q for a host of reasons we have no idea.

If you can tile? You can probably shim off base molding, and re install.

It's a few hundred dollars to a fresh floor in a porcelain tile. Or it isn't. Doesn't make the suggestion "bananas" : )

This site assumes every project needs to be perfect. As a landlord, rehabber and flipper… I would have lost well over a million dollars following the advice of this site just in the last ten years. What you are saying really is there is a chance this $40 repair will not look good so consider spending $1,500 on the repair that you know would.

If you are worried about the grout match carve out a piece of grout in an inconspicuous place and test it. Make sure the tile match is acceptable by placing the new tile in the middle of the floor. Remember this is the tile under a vanity, that is going to be in shadows most of the time…

We know it is 1500.00 based on what?!

Tell us the bath size ....someone? Anyone?

This is when the OP leaves Houzz for an online Tilers Forum where they can get technical advice and options from the pros instead of designers.

I am assuming a small 40 square foot bath. The standard 5 x 8 door - vanity - toilet - tub linear arrangement. That gets you about 28 square feet of tile.

Without underlayment the OP is going to have grind the mortar off the subfloor or replace it. This is likely not an easy job or clean job.

The money is not the point… insert any reasonable amount of money in there and the calculus still doesn’t make any sense. If the OP could get an acceptable patch 70% of the time (which they can) then there is a 30% chance they wasted $40 and a 70% chance they saved the cost of a new tile floor. That point of indifference is like $120 for the new tile floor even if there was no more work, mess, or disruption.

Even if there was only a 10% chance of an acceptable patch it would still be worth it just to try to avoid the mess and disruption.

isn’t the patch sitting under a vanity?

I find it is always easy to spend other people's time and money.

First, they are tiles under the vanity and it is doubtful that anyone sitting on the toilet in there is going to judge the OP for the tiles under the vanity not being a perfect match. If they do... the biggest problem is not with the tiles, it is with the people you allow to sit on your toilet.

I had some shingles damaged on my roof in a storm, you can see where new shingles were added, do you think I should have spent $30,000 replacing a functional roof because you can see where new shingles were patched in? I am sure you do... because it isn't your $30,000!

Moreover, to actually prioritize this project we really need to know about the entire house. Maybe the rest of the house is perfect and putting extra money in this bathroom is a great idea or maybe it would be completely idiotic to sink one more dime than necessary into this bathroom at this time.

One of the very first things I change on any rental property is to get the vanity off the floor. I will either use a floating vanity or legs... if legs I always make sure they are capped. Vanities with particleboard toe kicks are one of the stupidest ideas we have managed to come up with in the last 100 years. So maybe the OP is remodeling their bathroom or maybe their vanity needed replacing as probably 90% of particleboard vanities do after only a few years.
