So what are some of the choices you have?
Move the bathroom to a bigger room in the house
This option is great if you have a spare bedroom that is not used and the current bathroom could be made into a small office or something more suited to the size of the room. This is also good if the bathroom is not situated in a very good place in the building
.Move a wall and use some of a room next door.
Do you have a room next door to the bathroom that you can make slightly smaller by taking some space from it by moving the wall between them into the larger room? Even moving a wall enough so you can put a vanity in the space created can make a world of difference to the room.
Use the small bathroom as a second bathroom and build a bathroom in a bigger room
This option works best if you have a bedroom next door. Putting a doorway through to the bedroom possible blocking of the current doorway if it leads to another room will create a separate bathroom for the occupants of the bedroom. Then you remodel a larger room in the house into a bathroom. The main thing to consider here is the plumbing because it can be costly to get new pipe work installed.
Build an extension
If you do not have a spare room you can convert you might think about building an extension to the building to house a new bathroom. This option will be expensive and you will need professional help to plan it but it can be worth it.
Work within the space you have
The remodel options mentioned above can be expensive to do because you will need professional help with the design of your small bathroom remodel, the cost of moving and things like plumbing the new bathroom. So what do you do if you do not have that much money? You have to work within the space you have.
This is not as bad as it sounds, with a little planning and a few simple tricks like painting the wall a lighter color and putting a big mirror on a wall which both makes a small bathroom look bigger your small bathroom remodel can be a success.
