@magspag Thanx for the advice. We wanted to save some cost by not replacing the floor tiles, as well as save by retaining the upper cabinet in its current grey shade. Guess we will go for all-black for the cabinets: both below and above the counter; and put in a new counter-top that contrasts--maybe, a light coloured granite or slate. Examples for this color-scheme are in the ideabook

So many grays turn blue. after much trial and error for bdrm, bath and water closet , i'm happy with Benjamin Moore Horizon and Behr ultra in Burnished Clay. Neither look great on the card but they dry to a soft neutral gray. worth getting samples to try.

Flooring materials can be different and you cannot use the same cleaning material for all,and of course, it always depends on the use of them.Although,you can clean the tile,marble or any surfaces by yourself but its recommended to consult the expertise of floor cleaning service provider because they are professional in that services.Along with the regular swabbing and sweeping,one also undertakes additional functions to ensure optimal cleaning.This includes waxing, burnishing,stripping,buffing,and scrubbing.Our friendly staffs provide High-speed polishing that will give your floors a professional shine.

Thanks for both of your responses CUBSpaces team and Shweta from Shades studio. It really gives a clarity about possible consequences. I am now doubt free about changing whole things in Bathroom as it will be interconnected. However will appreciate your opinion on few things: 1. Kitchen wall tiles: I have those from countertop height to roof(almost area of 6X15 feet) which are good and not hollow. I changed countertop 5 years back without any damage to these tiles. It might cost me another 10-15 K, but I feel the whole process and quantity of wasting old good tiles makes me little sad. 2. kitchen countertop: Made new around 5 years back. I don't expect to get it all intact. But large pieces can be cut and can be used as top for other freestanding structures like dishwasher, front load washer, heighten base cabinets, etc. 3. Plywood: I don't mind giving enough labour charges for old sheets recycle. I am planning to use doors, loose sheets(like kept on bed frame of settee frame.) or parts of big frames like settee. I am keen on reducing waste than to save money. You can see various DIY ideas by western people, who remove or sand laminates and re-paint furniture, or carefully remove hollow tiles and re-attach them. Some are also re-painting ceramic tiles. I am just asking myself: Are we creating more and more waste by use and throw approach every 10-15 years, just because we can afford it?
