I'm probably asking a really silly question but here's my problem.

I've tiled a few rooms before and the way I start is to screw a piece of wood into the wall low down where the second row of tiles will start I make sure this is level with a spirit level so I have a straight and level foundation to start on and then when I've tiled the entire room I take the wood away and cut the lower tiles to fit. I don't like the idea of starting at the bottom as it will be difficult to ensure its level.

Now my method doesnt lend itself to a wetroom where I've tanked the wall as I don't want to compromise the seal by drilling holes for rawl plugs!. Where would you professionals begin?

Walls covered in ardex WPC, tiles are 300x600 porcelain. I have a laser level to assist

With that I’d cut the bottom row in and just tile from floor .
But if you do put battens on, when you take off fill the hole with silicone , or just patch it up with tape and paste, it’s exactly the same as covering screwheads or around pipes

As wilder says, nothing wrong with doing it either way as long as your tiles are level...I do use laths...not on commercial work as I mark a datum line after using a laser level.....but in bathrooms or wet rooms most of the time I do as I find it works fine in smaller areas.....then drop the bottom course in last ......just double check your first course you fix on top of your wooden lath as you may need to just tweet with some wedges as a wooden lath is never perfect.....if your walls are perfect and your adhesive is has an extremely good non slip properties the use a datum line & work down but I can’t remember the last time I tiled a straight wall or floor for that matter....good luck

Personally I always cut the bottom row in and work off it, not used battons for a long time, but whatever works for you is ok, fill the holes if you make any.

You could always gauge down from your datum line and set up your laser level at that mark ,thus cutting your bottom row first then work up & if you want to you could always check with a level just to air on the side of caution
