How difficult to replace fixed tiles

[Miles]

Put up tiles yesterday but I'm too much of a perfectionist, so I want to change an edge near the door that I want 1 cm wider. How difficult is it to chip away about 15 edge pieces that are about 2-4x4-8cm in size... and then, of course, lay new tile pieces that are one cm wider?
... I haven't grouted yet!

Is it an advantage to take them down immediately (put them up last night) or does it matter if I hear them today or later in the week?

The tiles are fairly easy to remove, but the adhesive will require mechanical removal. Since it's at the end near the door, the waterproofing doesn't matter. Start tearing down...

Shouldn't be a problem, a smaller chisel and light on the hammer and they'll come loose. Then scrape off the fix, it's not a major job either but be as careful with the surface as you can.
You're right, if it bothers you now, it will bother you as long as you live there
