Thanks for all the suggestions. I have used grouting the same colour as the tiles and finished with a smaller tile at the top allowing for a decent gap below the ceiling. I hardly notice it! Very happy with the result.

You're welcome Jen. I think it was $70 shipping Australia wide. All feature herringbone tiles I'd looked at were so expensive and I found theirs for 65/ metre. I ordered extra and I'll use them for the Landry too.

You will need a bath with three or four tile flanges to match the one in the first photo. It has to do with complying with the building regulations for waterproofing and protecting the timber framing that is under the tiles. If the edge of the bath where it meets the tiles is not properly protected from water seeping through then concealed wet rot could start, and eventually everything will need to be ripped out, and built again. Sometimes even the timber floor joists under the bath rot out and need to be replaced. So I would do your research and co-ordinate carefully with your builder to ensure that the details are correctly built. Some builders will not go to the trouble of getting it right as they don't care if your bath falls through a rotten floor in ten years time. Quite often your choices in the bathroom should also take into account the long term functionality of the bathroom, rather than just the aesthetics.

Don't put in a false ceiling. Raked ceilings are lovely and that extra air space in a bathroom is a big bonus. If I'm reading correctly, your showers are on the high wall, so logically taking tiles to the standard 2100 height would make sense. Your could choose to continue at that height all the way around, or drop to a lower height outside the shower area. It's a matter of deciding what look you like. You could, for example, change the wall covering outside the shower area to make the shower a feature. Use a feature paneling elsewhere, for example. Run a dado rail around outside the shower and tile or panel only up to the rail. Or use a feature tile over the basin and tile only up to the mirror or medicine cabinet. I used to be with Kate, hating tiles to the ceiling, but we just had our bathrooms redone that way and I love them, but we added interest by using a 2100mm wall in front of the shower with a feature black trim top and using the floor tile for contrast on one wall. We had tiles to the ceiling before the reno and I hated them because they were bland and uninteresting so the whole effect was drab. We took care to replace them with tiles that pop a little, and trims that stand out, and feature marble vanity basins so that the eye is drawn to a feature as soon as you enter. I don't think the tile height matters nearly as much as choosing the right tiles and accessories and creating a look that catches the eye immediately - go for a wow factor somewhere! It might be the vanity, some feature timber trims and vanity cpd doors or dado rail, or some interesting shelving over the bath. Co-ordinate with care and the tile height won't matter a jot.
