Loft Space Ensuite

If you’re converting your loft space to create additional bedroom accommodation, it makes sense to incorporate bathroom facilities on the same floor for convenience. If the loft conversion is to be a new master bedroom, an en suite bathroom should be seen as essential.
An en suite bathroom need not take up much space, but it is important to make sure that the space allocated has sufficient headroom for features such as the WC, basin and shower to function comfortably.
A shower room will fit into a space measuring only 1m by 2.6m, with a WC, basin and a 900mm square shower tray – full headroom is required here, but the ceiling can start to slope down over the WC cistern. A bathroom will need at least 1.7m by 2.3m floor area to incorporate a WC, basin and standard bath. The ceiling height can be reduced over one end of the bath or the side of the bath, and behind the cistern – so it is sometimes easier to fit a bath into a loft room than a shower.
Putting in a dormer window can create extra headroom, but if this is not possible, a rooflight can still add 150mm – which can make all the difference over a WC or basin.
It is not essential to have a window in a bathroom, but if it is possible it is desirable. Planning permission isn’t usually an obstacle for a small dormer window or gable window, providing you use obscured glass and no part of the window opens below 1.7m. Ventilation is essential to meet the Building Regulations, so an extractor fan will be needed to provide both background and rapid extract ventilation.
If you can’t connect into a soil pipe, you can still create a bathroom anywhere in the loft and connect it using flexible small bore waste pipes and a pumped unit with a macerator.
If your plumbing works from a header tank, this will need to be moved higher than the loft bathroom taps or showerhead to create pressure. It would therefore be easier to fit a mains pressure plumbing system, with either a combi boiler providing instant hot water on demand, or a boiler and unvented cylinder. A mains pressure system requires at least 1 bar of pressure – enough to lift water 10m. If the local mains pressure isn’t adequate, water could be pumped from a coffin tank to create the necessary pressure.
Make sure your existing boiler has sufficient power for your additional bathroom facilities. If you have a combi boiler and it is too small to power another shower, you could fit an electric shower that produces its own hot water on demand.
It is possible to use a flush shower tray, or walk-in shower tray in a loft bathroom, but the floor level may need to be built up to accommodate the waste trap, plus the waste pipe may have to be boxed in at ceiling height in the room below.
For a walk-in shower, it is best to use a pre-formed tray (such as Impey, Marmox, or Wedi) with an integrated trap and to tank the whole floor, dressed up the walls by 100mm, so that the water can only escape down the trap.
A radiator towel rail is usually sufficient to heat a small bathroom, but it is nice to have underfloor heating too, especially if your floor is tiled. Electric underfloor heating mats are inexpensive and will only raise the floor level by 3-4mm, so they can be laid beneath tiles.
