Let's be honest, a tight bathroom can be annoying. You're constantly bumping into things and perhaps there are some things like blow-drying your hair that are just easier to do in another room altogether. Until you have your dream bathroom, there are some things you can do to make your bathroom more bearable.
1. Avoid Swinging Doors
If you can, find a vanity with overlapping, sliding doors that take up a bit less real estate. You can also do an open vanity with baskets underneath or a console sink with metal bars that double as towel bars. If you have a tub/shower combination or stand up shower consider a single stationary shower panel on the showerhead side. This will eliminate the need for space dedicated to a door swing.
2. Get a Shallower Vanity
A typical vanity depth (countertop included) is 24", however I have seen them as shallow as 19 1/4." Also, a vessel sink usually allows you to have a smaller vanity, under-mount sinks require a lip to actually attach it to the underside of the countertop. When you have a tight space it's a game of inches. One thing to keep in mind—be realistic. If you currently use every inch of your vanity, you probably don't want to make it smaller.
3. Upgrade the Radiator
If you've got an old house you know what I'm talking about. Radiators give off good heat, but they can take up a lot of space. There are more modern radiators with profiles as shallow as 2".
4. Be Strategic with Your Towel Bars
As I said in #2, you can find console sinks with metals bars that double as towel bars. Another option is using your shower enclosure for towel bars—if you are getting a new shower enclosure and plan ahead, the stationary panel can have holes pre-drilled for your towel bars. If you just don't have the wall space for a towel bar try hooks!
5. Lose the Opaque Shower Curtain
The more visual barriers you have, the smaller a room will feel. An opaque shower curtain makes your shower seem like a barrier even though there is space behind it. One solution is to replace this "wall" with a transparent shower curtain or a single glass panel. In either case, the downside is that you need to keep your shower a bit neater—everyone is going to see your body wash and hair products.
