Hi! Me again! saying - a combination of the two :-p http://www.grespania.com/coverlam.php?sec=int Like we did in our bathroom, you could also use that 3 mm thin tile that comes in panels as large as 3X1 m. You'd need a good tiler to install it (it needs an almost perfect horizontal/ vertical surface) and can go for an extremely thin grout line. And it's not as expensive as back painted glass or resin panels, it costs just a bit more than an average, normal ceramic tiles.

I would (if the tile stripes line up) do the back wall that has the shower and the bath on it with the striped tiles, but put them in vertically. Since I'm not a huge fan of corner baths (they always look dated to me) and you have space for a free standing tub, I think, I'd go for something like this... But, if you go for the plan you have now, I still think that the back wall in the striped tiles will look modern and not overpowering if you keep the rest fairly plain.

Is it possible to sandblast thin 5mm lines (about 15cm apart) on large 600x300 marble tiles (to make it less slippery) to be able to use it on the floor of a bathroom shower area? The tiles are not on the floor yet, so I will be able to take them to a sandblast shop.

I think everyone will have a different opinion on this. Me, I prefer shower panels. I have Nuance by Bushboard in my shower cubicle. Soooo easy to wipe down and keep clean. However I didn’t remove all the tiles that were already in the shower room as they were neutral and half way up all around the small room. They don’t get ground in muck on the grout like a shower area does. I don’t like to see a bathroom/shower room tiles floor to ceiling. You do need in all the way up in the shower cubicle area, but it’s not necessary everywhere else which then gives you the opportunity to add colour with emulsion. In a few years time when you have to decorate you can just paint the top half which will make it feel as though it’s had a change.
