en suite bathroom in a loft conversion

If you’re switching your loft space to set-up additional bedroom accommodation, it seems sensible to include en collection bathroom facilities on a single floor for convenience. In the event the loft conversion is usually to be a new master suite, an en collection bathroom should be observed as essential, and can likely increase the value of your house.

An en collection bathroom do not need to take up much space, but it’s important to make certain that the area allocated has sufficient headroom for features including the WC, basin and bathtub to function easily.

Planning for a loft en collection layout

Start your en collection task with a level floorplan of the loft space and tag a dotted lines showing where in fact the ceiling elevation reduces right down to 1.8m, 1.6m and 1.4m. This may allow one to plan where in fact the foundation and other furniture can go while departing sufficient full-height space so that you can move around and it’ll show the area left to generate the bathroom.

Investing in a dormer screen can create extra headroom, but if this isn’t possible, a rooflight can still add 150mm — which will make all the difference more than a WC or basin.

The toilet will typically be made using timber studwork, clad in sea ply and tile support plank (inside) and plasterboard (outside), with the voids filled up with acoustic insulation.
Metal frames can be found to make into stud wall space for a wall-mounted WC with a hidden cistern, or a wall-mounted basin.
The voids between your studs are well suited for concealing the domestic plumbing, land pipes, wiring, hidden cistern and mixers for taps and showers.
You may have the ability to use voids in stud wall surfaces for forming storage space niches.
A bath will match a space calculating only 1m by 2.6m, with a WC, basin and a 900mm rectangular shower holder — full headroom is necessary here, however the ceiling can commence to slope down in the WC cistern. Your bathrooms will require at least 1.7m by 2.3m floor area to include a WC, basin and standard shower. The ceiling elevation can be reduced over one end of the bathtub or the medial side of the bath tub, and behind the cistern, so that it is sometimes better to fit a bathtub into a loft room when compared to a shower.

En suite light and ventilation

It isn’t necessary to have a screen in your bathrooms, but if it’s possible it is suitable. Planning agreement isn’t usually an obstacle for a tiny dormer windows or gable windowpane, offering you use obscured a glass and no area of the window starts below 1.7m. Venting is vital to meet up with the Building Polices, so an extractor supporter will be had a need to provide both record and rapid draw out ventilation.

Planning the plumbing

You should indicate on your floorplan where any existing ground pipes for restrooms on lower floor surfaces can be found, as it’ll be simpler to hook up the new en collection to one of the than to set up a new garden soil pipe. Although this might also be possible, depending on located area of the drains outside the house — look for the inspection chambers or speak to a plumber.

Connecting drinking water and drainage

If you cannot hook up into a ground tube, you can still make a bathroom any place in the loft and hook up it using versatile small bore throw away pipes and a pumped product with a macerator.
Hot and frosty plumbing related can be branched faraway from a preexisting bathroom on to the floor below, and the pipes concealed in something duct, or in the rear of a cupboard. Adaptable plastic domestic plumbing can make retrofitting in an easier way than rigid copper tube.
If your plumbing related works from a header container, this should be moved greater than the loft bathroom taps or showerhead to generate pressure.
You’ll be able to use a flush bathtub holder, or walk-in bathtub holder in a loft bathroom, however the floor level might need to be developed to support the waste snare.
To get a walk-in shower, it is advisable to use a pre-formed holder with a built-in trap and tank the complete floor, decked out the surfaces by 100mm, so the water can only just evade down the snare.
You may want to fit a mains pressure plumbing related system, with the combi boiler providing instant warm water on demand, or a boiler and unvented cylinder. A mains pressure system requires at least 1 club of pressure — enough to lift up normal water 10m. If the neighborhood mains pressure isn’t sufficient, normal water could be pumped from a coffin fish tank to create the required pressure.


A radiator towel rail is usually sufficient to heating a tiny bathroom, but it is nice to acquire underfloor home heating too, particularly if your floor is tiled. Electric underfloor warming mats are inexpensive (around ?100 for 6m?) and can only improve the floor level by 3-4mm, to allow them to be laid beneath tiles.
