How to Design a Loft En-suite

Creating an en-suite provides a great way to add extra value to your home, and if you’re converting the loft space so you can have an additional bedroom, it makes sense to include a bathroom on the same floor for convenience. Here are some useful tips and advice on how to design a loft en-suite.

Loft bathroom

You don’t need a lot of space to install a basin, toilet and shower, but you need to ensure that there is sufficient head room for these elements to function properly. A shower room can fit into a space that measures just 1m by 2.6m, but if you want to install a bath instead of a shower you will require at least 1.7m by 2.3m.

Plan the layout

Before you start any work or choosing any products first begin by creating a scale floor plan of the loft space, and mark a dotted line where the height of the ceiling reduces down to 1.8m, 1.6m and 1.4m. This allows you to plan where to position the items in the bedroom, and it will show the space where you can create the en-suite bathroom. Extra head room can be created by fitting a dormer window.

In a loft en-suite the bathroom will usually be created with timber studwork, which is then clad in marine ply and tile backing board on the inside and plasterboard on the outside, while the voids are filled with acoustic insulation. These voids are great for concealing the plumbing, pipes, wiring as well as for creating storage niches too.

Ventilation

If you don’t have a window in your loft en-suite it’s vital that you install an extractor fan to meet Building Regulations.

Plumbing

On your floor plan mark on where there are any existing soil pipes for the bathroom on the lower floor as it will be much easier to connect the new en-suite to one of these, rather than install a new soil pipe.

The hot and cold plumbing can be branched off from an existing bathroom and the pipes can be concealed in the back of a cupboard.

If the plumbing works from a header tank, then it will need to be repositioned higher than the taps and shower to ensure that enough water pressure is created. So, it might be easier to have a mains pressure system with either a combi boiler fitted that will provide hot water on demand or a boiler and an unvented cylinder. It’s important that you check your boiler has enough power for your extra en-suite.

Electric showers are ideal for supplying instant hot water, especially if your boiler is too small to power an extra shower.

Heating

Electric underfloor heating is the perfect option for a small loft en-suite and will feel great on chilly winter mornings. Heated towel rails are also ideal, as they keep towels warm and dry, and provide a background heat to the room.
