There can be little doubt about the impact that can be made by Bohemian bathroom designs and the fact that this is not a style that is used that often is an absolute tragedy. You just have so many options with this style of bathroom and as long as you follow a few basic rules there is little chance of you not managing to get that wow factor that you are looking for.
With the Bohemian style you can afford to be quite bold with the color scheme, so if you want to go for a daring purple or a vibrant blue, then feel free as it is all about being allowed to express yourself. If you do not feel like a block of color covering the walls, then how about a section of tiles, even if they are on a piece of furniture, where they are bright or with a bold design as it will still work spectacularly well.
For the fittings, then you need to avoid the modern look and instead look at getting something a bit more traditional with a roll top bath being the best. Elaborate taps are also a welcome addition and look at having the variety that actually spells out hot and cold for an extra special touch. Any furniture can be a mismatch with different woods and designs coming together in a free flowing final look.
Just to finish everything off do not be scared to add various trinkets and just making the bathroom look very busy at all times and from every angle. Never see anything as being too strange because the best Bohemian bathroom designs are those that are always a work in progress with items changing, color schemes being altered with a mismatch of colors always being a winner, and the room ultimately being a statement by the owner where they allow their creative side to run wild in a room where they are restrained by its size.
Go ahead and have fun with it and see where it leads you.
