Hi,
I've employed a tiler to tile bathroom walls. The floor is already tiled in the same tiles. The tiles has not matched the grout lines on the floor to the tiles going up the walls se basically each vertical tile has a horizonal floor grout line in the middle. Id this normal\acceptable? I'm not sure if I'm just being pedantic or whether its just wrong. Thanks!

Yes it's acceptable. However it's something you'd have needed to request at the time of the quote. It's actually pretty hard to do. The room needs to be perfectly square as if your room is wider at one end than the other (even by an inch - but I'm sure it'll be more) you're not going to be able to follow both parallel walls with your grout lines.

If you'd have requested it during the quote period, he'd have been able to check to see how possible it is, and if he can just have one wall or something not perfectly matching but the other three he could. But it's a lot of time measuring and he'd have needed to know the tile size at that point etc.

But yeah, in general, perfectly acceptable. And not often requested. Seen some good (and possibly pretty lucky) bathrooms over the years on here though that did manage to pull it off. Very few though.

It may not have been possible as the floor was tiled first without having to take the walls into consideration.

Are the tiles square? If they are rectangular it's only possible to get the grout lines to run in on two of the four walls.

Thanks so much - makes sense when you think about it! My other question was about sealant. I have bought polished porcelain tiles. I read that these sometimes need sealing. They seem very smooth and hard and I have had the ones on the floor for 6 months without sealing and without any stains appearing. Is it ok to leave the wall ones around the shower without sealing too? Thanks for your help and expertise - much appreciated!

It wont hurt to seal them providing the do actually need it though, this would also seal the grout and help keep it clean

- in an ideal world if the tiles are exactly the same size it would have been possible to match the joint lines on all 4 walls. However the floor having been completed 6 months ago and your new tiler just doing the walls now, would lead me to accept that bonding will not now occur.

However depending on the setting out of the floor and the cuts that would appear in the corners of the wall, it may still have been possible for bonding but without seeing the work its impossible to call.

It is something that I would have discussed with a client - pointing out the alternative choices.
