32 Sqft is a reasonable space for bathroom, though you may not be able to put a bath tub. Here the tips.

1) Your wall colour should match the colour of the closet and wash basin. If they are Ivory/cream then you should go in for a smilar wall colour. similarly, if they are white then go in for white colour paint.

2) Ensure that you lay tiles atleast till 7 or 8 feet on all sides.

3) Have a small projection about a brick size behind the closet. so that you can place small plants in glass vases or bottles.

4) Fix two corner glass shelves ( Half circle ) to keep your toiletries. It is easy to clean, occupies less space and look elegant.

5) Place one or two small paintings on the dry side of the bath room away from the showe. It can be a natural scenery or any modern art painting.

6) If you are laying fresh tiles, fix handles near the closet as it would easy for elderly people in the house to use the WC.

I hope this helps.
