Sorry but I don't understand your pictures. You are talking about 2 bathrooms but we see only one floor plan. Is the 1.52M x 2.24M the 5 x 8 bathroom in your dilemma title. If so, can we see the floor plan of the 5 x 9 bathroom? Is the space with a small rectangle in the middle the extra 5.5 x 4.9 ft space you mentioned in your dilemma? Also 1.52M x 2.24M is in reality 5'0" x 7'4". This is 8 in. less. It can make a big difference on how to place fixtures in a bathroom.

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.

Just to clarify, changing the direction of the comod would give you more space outside the cubicle door. This is however considering you get a smaller tub, it would otherwise be difficult to mount. The present location of the comod seems inconvenient since it does not leave a lot of room and cannot be flipped in lieu of the column. If you can device a way around it, the plan is good. Di consider an independent, standing basin. They look good and take up lesser space. There will however be lesser and not to mention separate slab space.
