Small loft ensuite ideas
Having a loft bedroom with an small loft ensuite is a preferred choice by many people due to the convenience and style. Ensuite bathrooms are becoming more of a thing, even if its not in a loft. Here is a small loft ensuite idea that we have built recently.

Loft conversion wet rooms

If you’re having to fit your bathroom into a particularly small space, a wet room may be an option. When creating a wet room, remember that the floor needs to have a slight gradient for drainage and the whole room will need to be waterproofed.
Loft conversion shower room ideas

When space is at a premium, doing away with a bath altogether means you might be able to have a larger shower. To create a light and airy feel in a small space, like the loft conversion shower room ideas above and below, using white or light colours helps to make the space look larger.


Bath only

If your space has a low ceiling, going for the bath only option could be the best use of space. If possible, add a skylight, so the light falls over the bath creating a tranquil refuge for you to relax in.
Bath and shower combo

Is your loft bathroom the family bathroom? Then you might want to go for a bath and shower combo. This practical set up uses loft space up wisely and gives you the best of both worlds.
Loft Conversion Ensuites

When it comes to an ensuite, you can create any type of bathroom you want depending on the space available. Many opt for a large walk in shower, but like the bathroom above, you can create the perfect ensuite with a roll top bath and maximise space by not having a wall.

How Do I Get Light Into My Loft Conversion Bathroom?
One of the best features of a loft bathroom is the possibility of flooding the room with light. In most houses the bathroom can be the darkest room in the house, only having a small window or even no window at all. When you open up the loft and use some of the space for a bathroom you have the opportunity to create a light filled room, enjoy the view and still retain your privacy.
Skylights are the key to creating a light and airy bathroom, they can turn difficult loft spaces into light filled havens you want to spend time in. In regards to practicality they’re also great for ventilation. The owners of this property, pictured below, added a stylish skylight above their bath, giving anyone taking a dip a chance to enjoy a bit of cloud spotting or stargazing.
