Greetings all, new here...looks like a good forum Setting out tiles above the bath. Tiles are Wickes Amaro porcelain 308 by 615 (Except in real life they're 305 by 610) Bath to ceiling is 1865mm and I just laid out 6 tile with 3mm spacers and it ended up as 1840mm Even with a generous 5mm silicon gap at the bath I'm still left with 20mm at the ceiling. Advice please...do I grout it? Do I fill it and paint white? Or do I bite the bullet and cut half a tile at top and bottom? Is 20mm too much to hide? Thanks!
