Can't figure this out

[Trevor101]

Hi, first time here so hopefully not a silly question. I am tiling a bathroom for the first time with 1200mm x 600mm porcelain tiles horizontally and a room height of 2445mm, 5x 2mm grout lines

Using 4 full tiles I am left with 37 mm sliver cut.

Cutting the tile with one piece on the bottom at 300mm and one on top 337 or so would add considerable expense.

I would consider dropping the ceiling if this is not a ridiculous suggestion

Dose anyone have a better idea or advice

Yes cross batten the ceiling with 2x1 roofing batten, then 12.5 plasterboard and skim- you’ll be there.
Check first for level and run offs, use CLS (38mm) instead of batten if levels are off as this will give you another 15mm of leeway overall.
