Adding an en-suite bathroom? Here’s what you should know


The dream for most of us is to have anen-suite bathroom that allows scampering between bed and bath (or toilet, orsink) to become so much quicker and easier. Fortunately, creating an en-suite(doesn’t matter if you prefer ‘en suite’, ‘ensuite’ or ‘en-suite’, it’s stillthe same thing!) isn’t that much different from creating an ordinary bathroom;however, seeing as it forms part of your overall bedroom scheme, it doesprovide some extra considerations.


If you’re lucky enough to have a spaciousbedroom that can be partitioned off, then adding an en-suite bathroom could bea fabulous way to up your home’s sense of luxury. And let’s not forget howhaving an en-suite influences your home’s value in a positive way.


But before you start dreaming about whatcolour textiles you’re going to have in your en-suite, let’s consider a fewpractical matters first… 


1.    How much does an en-suitebathroom cost?

When combining labour, fixtures, fittingsand finishes of a typical bathroom, the average cost of adding an en-suitebathroom is about £3,000. But keep in mind that the final amount can varydepending on the location of your bathroom, as well as finishes and size.


To save costs, it’d be better to add anen-suite directly to an existing bathroom on the same floor, or above abathroom on the lower floor. The reason for this is because it becomes morecostly to redirect plumbing, especially soil stacks and waste pipes. And eventhough a small bore pipe with a macerator can be installed, this solution isnot ideal. A plumber’s day rates will also need to be factored in, but theamount of time such a project will take is quite difficult to determine.


After the plumbing has been sorted, it’smuch easier to estimate how much the appropriate fixtures and fittings willcost.


• Bathtub: Your typical low-end, acrylicmodel will cost from £70, yet a good-quality steel one can cost from £300 to£500.


• Shower: A basic electric shower is themost cost-effective option (to buy and use), starting out from £50. Expect topay between £100 and £200 for a stylish and functional unit. £200 is theminimum you can expect to pay for a power shower. 


• Shower enclosure: A crucial decision, forthis will influence the overall look of your shower. A typical shower tray andenclosure combo can start out at £150, but can climb up to about £600 for ahigher-quality model.


• Wet room enclosure: Depending on thestructural work, a wet room enclosure can cost upwards of £500 (which includeswaterproofing, plumbing, the shower and a screen).


• Basin: Available in various materials andfitting methods, bathroom sinks can severely alter your final price. A simpleceramic one will cost upward of £50, while bespoke models made for vanity unitscan start out around £100.


• Toilet: While a simple ceramic,wall-mounted toilet costs around £50, higher-quality designs will come inbetween £150 and £300.


• Faucets and hardware: Although generallyafterthoughts for a bathroom, these are vital factors that can definitelyimpact the final paying price. Expect to pay as little as £20 for a basicmixer, and upwards of £400 for a really luxurious design.


2.    How big must an en-suite be?

With all the essential elements included(shower, basin, mirror, towel rail, WC and appropriate lighting) in awell-planned layout, a typical en-suite bathroom with minimum dimensions canwork out around 1,5m x 1,3m. And with the help of a seasoned bathroom designer,you can ensure you make the most of your space.


Keep in mind that one can only go so far tosave space (like using a corner basin, corner shower, etc.). Going too small(the smallest size for a practical shower is 80cm quadrant) will just result ina bathroom that’s most unpleasant to use.


3.    Does an en-suite requirePlanning Permission?

If the work is happening in an existinghouse, then no Planning Permission is required. But if you want to add youren-suite bathroom to a listed building, Planning Permission becomes vital.


Remember that your project must also complywith building regulations. Should your new en-suite bathroom require rewiring,drainage alterations, the installation or changing of a heating system thatuses gas or solid fuel, and structural alterations, then approval from buildingcontrol is needed.


Remember that all electrical work must beconducted by a qualified electrician, and that any work to boilers or heatingsystems must be carried out by a Gas Safe-compliant engineer.


4.    Building new walls for anen-suite

If your en-suite bathroom is created out ofa completely new room or partitioned in an existing room, then extra walls willbe needed. These will normally be stud walls created with a timber frame withplasterboard over the top. To avoid dampness problems, pick water-resistantplasterboard.


For a bathroom, structural metal componentsthat support the weight of wall-mounted basins are available. This cavity inthis type of wall is also ideal for hiding piping, cisterns, wiring and extrastorage.


Excluding internal works (like plumbing andwiring), building a stud wall will cost around £15 per m², and this needs to beplanned beforehand.


5.    Heating and plumbing for anen-suite

Planning on using a combi boiler (whichprovides hot water whenever needed instead of requiring a cylinder)? Then youmust ensure there is a sufficient flow of hot water for your extra bathroom.And check that your water pressure is sufficient for your mixer taps and showerfittings.


If you want to use heated towel railsinstead of radiators, expect to start paying from about £30 for wall-mountedoptions. High-end designs can cost as much as £500, which excludesinstallation.
