What tools needed to tile a wet room in marble?

[Pigglet]

I'm about to start tiling our new ensuite in 400X400X12 marble tiles, 26 square meter in total. After this I'lll have another 2 bathrooms to do which are quite a bit bigger plus a kitchen.
I want to get everything I need to do a pro quality job now as opposed to start and find I need X, Y and Z later on.
So far I'm thinking I'll need:
Decent tile saw, I've shortlisted a rubi DW 200 LP
Mixing whisk and bucket
Tile sucker for moving and positioning, especially If I make a mistake.
Rubber mallet
bucket trowl
notched trowel
wash boy for grouting
grouting float
Thats about as fa as I've got so far, any advice or input would be greatly appreciated

Add good quality knee pads to your list. And stabila levels. Wouldn't bother with the washboy, does nothing a bucket and rounded sponge won't do. The £50 you'll save on that will buy your levels and pads.

Thanks all the gear. I've got some pads but will invest in some stabila levels.

Anyone used a vitrex power pro saw? I know it won't be as well made as the rubi but given the saving thought it was worth a look???
