Tiled skirting

Pretty much, although you put the stainless trim on first as it has a lip which goes behind the tiles. I'd use something other than grip fill though.'Stixall' or 'Sticks like' is better to work with although more expensive but you'll probably only need a couple of tubes anyway.

 

I am not a tiler, however here are some comments based on my recent experiences doing three bathrooms!

Your cut pieces will be less than 119mm as there is the wheel thickness. You need to get them all identical so I would suggest setting it for 110mm. You will have 3mm below the tile, the tile width, a small 1 or 2mm grout line above and then 2mm of trim which would give a finished height of 116/117mm.

The tiles may have a bevelled edge - it will look odd if one or two have this and the others do not so your cutting may need to take the edge off and thus going for say 110mm will allow for this.

Some diamond wheels do take very fine chips off the edge, get a tile sanded to chamfer them slightly.

Do you want the joints to line up? Sometimes it can look wrong, so before you commit, try placing them and then placing them with a 300mm offset.

 

You will be pulling the old skirting off so that should leave bare plaster. Give it a good brush with a wire brush to key the surface and then use Ardex P51, 1:2 dilution, to seal it. Then get a decent tile adhesive such as Ardex X7 which you mix as required.

Apply that to the tiles, leaving the top centimetre or two clear and fit into place, move around as desired to get it into place, some of the adhesive will move up to fill the gap and when you are happy that the tiles are in the right place, gently back fill the gap leaving a couple of millimetres for grout or filler. Doing it this way minimises the amount of overspill onto the wall that will need cleaning off.

When finished use an appropriate coloured grout to fill the remaining wall to tile gap.

A Pro-tiler will probably find errors in my method - however, it works for me!

May also be worth getting a bag of packers/shims http://www.screwfix.com/p/broadfix-assorted-plastic-shims-medium-x-x-100-pcs/99189 and use these behind the tiles to keep the trim in place. Insert them a centimetre or so and then after a couple of hours, wiggle them and remove. The variable thicknesses will help deal with the uneven wall. I was told to use them between trim and tile to maintain a nice even grout line - and it worked.

 

Grab would (should) work however it could be costly. You need to get a good coverage behind the tiles so that impact with a cleaner or foot will not snap them, the gap filled to near top to minimise grouting ... You will find yourself using an lot of it, tile adhesive is a lot cheaper and probably better for the job.
