If the door is well painted I doubt if you will have a problem. A good coat of paint on wood work and wall surfaces is important if you have a lot of moisture in the room. If you can do some alterations to the space I would suggest you install an exhaust fan in the ceiling that vents moisture to the exterior, i.e. through the roof or side wall. Companies like Nu-tone and Broan make fans that have a moisture sensor that will kick on the fan while using the shower if you forget to turn it on. And these fans can be much more quiet than the typical bathroom fan. Some hundreds of dollars for the purchase and installation of this would be well worth it. I have seen bathroom ceilings covered with mold because the room has neither a neither a fan or window so you are right to be concerned.

Thanks Patricia and cpaul! I hadn't thought about glass. And I guess I should specify that a fully modular kitchen would not withstand the climate lol. The doors and Windows in General are traditionally made of teak wood and do warp somewhat but it's not a huge issue, so I fiured if all I am dealing with in the kitchen is the cabinet door it shouldn't be too hard to maintain. I actually ended up finding a blog about someone living in the tropical Philippine weather and how they covered their concrete counter with cabinets. Here is the link if anyone is interested http://myphilippinelife.com/our-philippine-house-project-kitchen-cabinets/ I think it turned out quite nice :) . This was their starting and final result. there are more photos in the blog. They basically recommended some prefabricated cabinets and strong hinges and screws for the wood frame.

Hello Radha, I don't think any independent comparison study will be available. You may go for a localised product with nano coating. BTW, almost every one uses a St Gobain, Modi toughened glass for these fixtures. Thanks, Amit Cornerstone Designs, Bangalore.

Rahul, You may have to change your entrance to the center of the longer wall. Once you are inside the bath in the center will be a basin. On your right will be bath area and on your left will be the WC. This should address your parents concern as well as your wet and dry area concern. Thanks for your kind words, we understand that a home is probably most important possession of any family. Just trying to advise to make the process easier for a few. Thanks, Nitin Cornerstone Designs, Bangalore.
