What kind of templates? A little more information would be helpful.

The energy efficient bulbs shown in the above photo suck the light is awful and they butn out quite often, if you want real energy savings go with LEDs they come in warm or cool light and you probably never have to chang a bulb as long as you live. They come in all kinds of wattages and can be retrofitted in almost any fixture.

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?

Many thanks for your valuable comments. 1. My intention of raised cabinets was to clean it daily, as cabinets that touch floor accumulate lot of dust and food particles below. If we rule out steel legs, any inputs on raised floor only of cabinet area and then cabinets?(Just like plinth in modular cabinets- but this will be permanent and of tiles) I have not seen such structure anywhere, so curious if it will work. Otherwise I will go with traditional ones. 2. Moving pooja out of kitchen is very difficult as other rooms are just enough for their function. Currently a small Mandir is attached on wall where Fridge is shown in layout. I thought the new area could be little extra for all pooja related things. Will like to know the reason of your recommendation, is it odd in whole design, or not suitable in area .. or anything else? How about moving it to corner of dining area?
