Cut out to-scale shapes of everything – loo, basin, bath and shower enclosure, for instance – and rearrange them until you find a layout that works best. Incorporate plenty of space between the elements and consider how the room will work with more than one person in there at the same time.
Check that the screen has a tight, robust seal where it meets the bath to prevent leaks. Well-made, durable trimming and fittings are advisable, especially if you’re choosing a bifold model that will be regularly pushed back to allow access to the bath.
Alternatively, invest in a shower bath that bows out at the tap end. Available in rounded and L shapes, it will give you more room to manoeuvre when showering. Remember, though, the wider end will mean the bath takes more water to fill. Combine the two by having a fixed-head shower above and a hand-held spray on the bath taps below. You’ll find the latter useful when bathing children or cleaning the tub.
Choose wall-hung fittings wherever possible. It will make your bathroom much easier to clean and give the illusion of space, too. Try to keep walls clear of clutter and consider fitting underfloor heating, so you can keep it toasty without taking up space with wall-hung radiators.
