Have these ceramic tiles been laid properly?

[Hozier]

Hi folks,

A friend has had these ceramic tiles laid in an outdoor office - also over underfloor heating. This was a pro job not DIY. Hasn’t yet been grouted.

Should there be this much (or any) discrepancy in height as shown in the images?

TIA

Joints less than 6 mm wide, 1 mm;
Joints 6 mm or more wide, 2 mm.

Last time i saw this standard of tiling i think Mick Jagger did the job .

Oh Jesus!

in a few places the differential is more than a 2p coin in height …

he’s trying to figure out whether to just accept it or get it redone.

having it redone would mean trashing the tiles and underfloor heating I think. Problem is that the tiles are 8x45 so the joints are quite frequent ….

What would you advise?

It depends on what was agreed. If it was a top rate professional, get it redone.

If the tiles were problematic i.e. low quality bargain basement tolerance then the tiler shouldn't have agreed to laying them in brick bond. It's trivial to check this before laying, usually even if they are "bad" all the tiles are bad in the same way so it can be accounted for. Sometimes you do get random extremely poor tiles that should just be rejected by any professional and it explained to you.

"There are permissible manufacturing tolerances for ceramic tiles defined in BS EN 14411; certain types of tiles, e.g. extruded or large format, might have permissible surface flatness irregularities that cannot satisfactorily be accommodated within the surface flatness tolerance permitted to the tile installer; this should be taken into account when evaluating the achievable flatness of a wall/floor tiling installation."

if they’re solid tile over it . it’s a bodge.

you sound like a top excuse maker. it’s a bodge mate, no amount of bs en 14411 or manufacturing tolerances can account for how p!ssed those tiles are.

I haven't made any excuse, as you and I have said the tiler should have refused to do the brick bond IF the tiles were bad. (They probably weren't).
