If you have a home, you can, of course, pretty much do whatever you please in it. Want a hot pink bedroom? No one's going to stop you! However, a painted wall is easier to replace, than say, multicolored tiles in the bathroom, especially if you're selling your humble abode in the near future.
According to The Times Herald, while it really all boils down to taste, homeowners should be careful before breaking out florescent bathroom accessories. "The brighter and non-conventional colors have a tendency to negatively impact buyers, the news source reports.
This means that, yes, it's fine to get a bright blue toilet and bathtub to match, but if you're planning on moving in the next couple of years, you might want to stick with neutrals instead. Another bathroom piece that you might want to keep contemporary to satisfy the majority of potential home buyers is your bathroom vanity. Try to stay away from overly designed pieces and stick to simple details and clean lines.
Of course, you shouldn't limit yourself when it comes to having a space that you love just because you're planning on selling your home. Instead, showcase your design aesthetics through pieces that can easily be replaced like bathroom accessories, or covered like the walls.
