you can either go for darker grey tiles or a beige. It all depends on how grey your wall tiles are and if they have any underlying colours - are they are purple or green grey etc etc. How does the ventilator affect the look. Do you have a photo?

You can use natural stone like marble for floor but do not use granite for floor at all as it is very slippery when wet. As for tiles do not go for glazed vitrified tiles for the floor for the same reason. ( floor becomes slippery once wet and may cause mishap) Go for ceramic anti skid tiles that are specially meant for bathroom floor. For wall tiles you can use whatever you like and then decide over the matching anti skid floor tile/ marble. Double charged vitrified tiles are usually used for flooring in rest of the house.

Hi Julie You can apply 2 coat of red oxide primer to the dry floor surface.That will serve your purpose. Ask for 'red oxide primer' and get half ltr turpentine also. Loosen the primer by mixing turpentine a bit..Apply the second coat after 6 -8 hrs.. Red-oxide primer is actually used on metal surfaces to protect it from rusting. Regards Jestin Thomas Renovart

Hi Shivam, the best size is either 300mm x 300mm or 600mm x 600mm. The reason is - smaller the tile size better the maintenance of slope to achieve drainage of water. Also, use anti skid tiles to avoid accidents.
