It is not a black and white world but...

that will be my toilet color scheme. Unfortunately, pipes are exposed in HDB toilets, but to turn the situation around,  the pipes could provide an industrial, rugged look.

 The homeowners chose to paint their pipes brightly, instead of hiding them. Isn't it brilliant? The flashy towels give this toilet more vibrancy too.

 The built in plastic pipes have been swapped for metal ones, which is fantastic! Now the toilet looks sanitary and sterile.

A black and white bathroom is classic, and adheres to the mid century modern theme. 

However, my BTO toilet comes with non-optional green wall tiles (featured above). I think it will be a pity to hack them off so I might just place indoor plants to complement the green tiles.
