How to Add an Extra Bathroom

Queue for the family bathroom rivalling the one for the Harrods’ sale? If you’re having trouble getting out the front door because your nearest and dearest are hogging the shower, it’s time to think about finding space and how to add an extra bathroom to your home.

Where to put your new bathroom

If your bedroom is generously sized, you could give up some floor space and partition it to add an en-suite that’s exclusively yours. Alternatively, consider a Jack and Jill en-suite where there’s access from each of two adjoining bedrooms – a strategy that’s often used in new builds. Stealing space from a landing or hallway could allow you to create the floor area you’ll need.

For a bigger additional bathroom, it can be worth sacrificing a bedroom. This used to be a no-no, but if yours is a five bed house with just one bathroom, you could make it more appealing rather than less when the time comes to sell, as well as improving your life while it’s still your home. Even in a smaller property turning a box bedroom into another bathroom could improve sale-ability, but think again if it means turning a three-bed house into a two-bedroom.

It’s not vital to have a window in your new extra bathroom, which can make siting it easier, but you will need efficient extraction to prevent condensation problems – and it’s required under the building regulations. You’ll also need to consider drainage because your costs will be minimised if your extra bathroom is close to the existing plumbing.

Choose bathroom fittings

A new bathroom designed for speedy morning routines may not need a bath – and a shower, basin and toilet combination will demand far less space than a full bathroom. Where the floor area is limited, opting for wall-hung fittings can create the illusion of a larger room as you’ll see the entire floor. Small bathrooms will also feel more spacious with pale paint and tile finishes, while hanging mirrors and picking high gloss furniture will boost light levels to make the room feel bigger.

Compact sanitary ware can also help your extra bathroom work well and look good, while a shower enclosure with a sliding or bi-fold door makes planning a functional layout simpler. With more floor area to play with but not enough for both a bath and a separate shower cubicle, think about the dual solution of a shower-bath. Designed to create decent showering space as well as sufficient comfort for a long soak, it could make your room more flexible.

Given up a bedroom? Make the most of the space if it’s generous. A freestanding bath will give your extra bathroom designer style and it can take up the middle of the room, be centred on one wall, or take advantage of the view out of the window if your home’s situated where you’re not going to give passers-by their own view of you. Do bear in mind, though, that a bath plus a bathful of water plus you is heavy, and it could be necessary to strengthen the floor in a room that was previously a bedroom.

Don’t forget the details

An extra bathroom equals more hot water use, so you’ll need to make sure your existing boiler is up to the job. Consult a qualified plumber for advice.

Unless you live in a listed building, you probably won’t need planning permission for a new bathroom within your home, but building regulations approval will be needed not just for the ventilation, but in respect of drainage, electrical safety and more. Contact your local authority for information.

Cost of adding a bathroom

If you’re shopping for a toilet, basin and shower enclosure as a package for your room, you’ll be able to find a combination of smart modern pieces starting from around £500. A suite with bath rather than shower can start from around £600. Opt for luxury or designer fittings and prices will increase to match.

Factor in, too, wall tiles, flooring and lighting – with choices ranging from budget to top of the range – plus paint for the areas that aren’t tiled, a towel radiator and as much storage as you require to keep the space clear of clutter, to which you’ll need to add plumbing, tiling and building costs.
