It can either look really dramatic or too dark, depending on the size of the room as well as your other components. I've attached a couple of images of our work using dark tiles, the smaller bathroom we have surrounded the bath with dark tiles but then balance it with an extra large mirror to bounce the light around the room. The larger bathroom we have taken the floor colour way onto the wall but used a different texture on the walls for drama. Hopefully this gives you more of an idea but you shouldn't to nervous of the room being dark, it's where you can create a contrast as well as textures. Look forward to seeing what you go with in the end.

Depends on the installer and what bamboo they're using.

Hi Anton and Dr Retro thanks for the comments. Anton that is really great advice, you've exceeded the explanation on the seller's websites and also you've provided a deeper understanding of the materials. What you say makes perfect sense, and it sounds like you have much experience with these tiles. I like the idea of applying wax over a sealer, this makes sense to me. Anton, would it just be a standard floorwax, such as this one for example (based on beeswax). And once you've applied wax over the sealer, then do you keep applying beeswax, or do you then reapply a sealer? https://www.ebay.com.au/i/292592220249?chn=ps&norover=1&mkevt=1&mkrid=705-139619-5960-0&mkcid=2&itemid=292592220249&targetid=480462538786&device=c&mktype=pla&googleloc=9071957&poi=&campaignid=1490767175&mkgroupid=63057291572&rlsatarget=pla-480462538786&abcId=1139416&merchantid=119185944&gclid=CjwKCAjw1rnqBRAAEiwAr29II20USj1b2llPlQ4eqngD-Paf9nrbms5ILxdyKEGnKhVKAErlLGCE0BoCSKYQAvD_BwE

Hi squirrel30. I ended up, on a professional's advice, having the whole bathroom stripped and redone. It actually worked out cheaper than any of the seemingly more innovative solutions. It seemed a shame to discard a lot of stuff that was in good order, but to get the result we wanted it proved the best approach and I'm delighted with the result. We had the floor pulled up and replaced with 600 x 600 textured grey tiles and 900 wide tiles in the shower with a grate at the end so in a very, very large shower we have only 3 grout lines and they are dark grey. We used slab tiles on the walls in the shower with dark grey grouting and 600 x 600 tiles elsewhere. Again resulting in very few grout lines, and no glass at all! I posted pictures of the main bathroom at Bathroom reno done! Thanks for the suggestions | Houzz AU The ensuite looks similar but has a twin vanity and larger shower with a tiled nib wall rather than glass. I'm still interested to know more about microcement but I can't get anyone to answer inquiries. I've responded to a dozen or so ads but nobody has ever bothered to contact me. Not sure I would trust a supplier who is that disinterested in potential customers!!
