Hi Roseanne, Need a bit more info like where the door is into the bathroom, specifically which direction does the window face if there is a window and if it's large or small???

yes to all, we did have the tiles professionally sealed, but sealing is not a cure all in my experience but I'm sure it helps considerable . my wife does buy those hand made goats milk styles soaps etc and I don't imagine there is anything more testing for stone, and yes it does mark. The Grey ( bane of my existence )granite much more so than the beige travertine ) I must admit though, the kids bathroom was almost non existent as one has sensitive skin and uses pump pack. I would also imagine climate, airing/ sunlight, volume of use and the time you have to manage it would also be contributing factors. We are way short on time and they don't get the attention they deserve, so I would suggest asking around, others may manage it better and it not be an issue. If your only doing your bathroom you may consider the risk factor not worth it for the volume, but for me, the advantage of travertine in the rest of the house far out weighs any marking issue in the showers, and wont stop me from using it again. To be honest when we sold the last house I just took to the shower with one of those paint scrapers with the razor in the end and most of it came off and it didn't detract from the look of the house. Sorry i have probably only muddied the waters even more, good luck with it.

without accurate dimensions my suggestion offers twin bathrooms with a central dressing area and biw accessible from the bedroom ...alternatively option 2 could have the storage swopped to the bathroom side to create a small entry hall to separate the wiw from the bathroom and, instead of a wall of glass, panels of horizontal or vertical glass and glass doors could enhance lighting and, based on my guestimated measurements, the twin bathrooms design offers much more than the required 16' of full height storage wall as well as a more comfortably sized dressing area

Hi Tash, I would stick with the white paint. You have noted you want timber, marble, grey, white and brass in the space and I feel that if you now add a colour to the walls that doesn't blend with the tiles that sit on the same wall there will be too many finishes in the space. Quite a few manufacturers have tiles similar to the one in your image so I'd check with your local supplier. If you do go with the subway tiles perhaps look for a handmade style tile and lay them as a herringbone style with white grout to get the same textural look you are after. Good luck! Regards, Kathryn.
