Tiling help please :) - Tile Advice

[Crumbs]

Hi guys after some advice please. Im re tiling a bathroom, the main wall is badly out of plumb, bellys in the middle, baths off by about 1.4cms, ceiling 1cm. Ive done most of the tiling accept the top and bottom row, slightly unlevel due to belly but only marginally and not noticeable.

The problem i have is the ceiling is out by about 1 cm. To the left i can fit a tile in nicely but unfortuantely it goes up over the width by this 1 cm requiring a tiny cut, no chance ill get these tiny cuts done. Anyway I knew this when planning, my bottom row will fit around 14-15cm cuts in which ill cut into the bath.

I was planning on cutting in the top row to the ceiling and cutting an extra 4-5cm of each cut so its not flush to the ceiling but is level with the ceiling and matches the bottom row almost.

Now at this stage i wish i pushed the bottom row up more

Does this sound ok to do or the other option i was considering was turning the tile on its side and doing this top and bottom, i can cut into the ceiling fine then, bottom row cuts will be smaller though.

Tiles are 20cm width by 25cm height, thanks alot

Turn them?
Put a 100mm cove round the top. Done.

Thanks bud. I know a bit drastic but it would mirror the bottom so dont think it would look all that bad. This is for a bathroom shower wet area. Could you link a suitable product pleaseee?

Cheers will use coving Now just need to find a suitable product. I am a coving virgin. Just standard coving for this and cut to it or is there a better product for wet areas ) tiles you can recommend? Much appreciated

Tile to full tiles and stick coving on top, no cutting in.
Standard coving is just that. Use tile adhesive to stick it up and put panel pins in joints while it sets.
Paint with a solvent based white egg shell or something similar.

No cutting in, music to my ears Would this suffice for the coving? Its polyurethane not plastic though, so not sure if thats a good idea in a hot shower area or is this what the paint will help with?

The rest of the bathroom has no coving, so id need to cove the whole room so it doesnt look out of place, how would i go from the coving protruding onto the tile /ceiling to a wall with no tile or would i just continue the coving and let it bridge back onto the wall.

Do i use spots of adhesive on the ceiling as well as on the back of the coving or some fast grip. Much appreciated
