Buying a new bathroom suite is one of the bigger home-improvement decisions most UK homeowners make — and one of the easiest to get wrong. The right suite fits your space, your budget and your plumbing; the wrong one becomes an expensive reminder that measurements were skipped. This guide walks through the decisions in the order you should make them, so you don't end up returning a 1700mm bath three weeks into the project.
Start with your space, not the showroom
The single most important step is measuring. Most returns and swaps happen because buyers fell in love with a suite before checking whether it physically fits. Before you look at products:
- Measure the length, width and ceiling height of the room, in millimetres.
- Mark the existing soil stack (the main waste pipe) position — this largely dictates where the toilet can go.
- Note window and door positions, radiator location, and where the hot and cold feeds come in.
- Sketch a rough floorplan. Graph paper or a free tool like SketchUp works well.
A typical UK bathroom is between 3m² and 7m². Ensuites and cloakrooms are often smaller, sometimes as little as 2m². Knowing which category you're in narrows the realistic product list dramatically.
Decide the suite type
“Bathroom suite” is a catch-all term for the combination of toilet, basin and bath (or shower). The main configurations sold in the UK are:
- Shower bath suites — a bath with a wider showering end, designed to double up. Popular in family homes and flats where you want both options without the footprint of two installations. Browse our shower baths.
- Bath and separate shower suites — bath on one wall, shower enclosure on another. Needs roughly 4m² minimum to feel uncrowded.
- Shower-only suites — a walk-in concealed shower or enclosure, a toilet and a basin. Often the best choice for compact ensuites.
- Cloakroom suites — a toilet and small basin only, for downstairs WCs under the stairs.
Skipping a bath entirely is fine for an ensuite but may affect resale value on your main bathroom — most UK buyers expect at least one bath in a family home.
Check what your plumbing supports
Your water system determines which products will actually work at the pressure they're designed for. The three common UK setups:
- Combi boiler (mains-pressure) — most modern UK homes. Runs most taps and showers well; thermostatic shower valves are recommended.
- Gravity-fed (tank in the loft, cylinder in airing cupboard) — common in older homes. Low pressure; you may need a shower pump, or you'll need to choose taps specifically rated for low pressure.
- Unvented (mains-pressure hot water cylinder) — higher flow than gravity-fed, easier to match with powerful showers.
Every tap and shower valve lists a minimum and recommended operating pressure in bar. If your system can't meet it, you'll get a thin, disappointing flow no matter how expensive the product was.
Choose fittings that fit the brand of everything else
Bathroom fittings are the bits you'll actually touch every day — taps, shower valves, towel rails, handles. Sticking to a single finish (chrome, brushed nickel, matt black, brushed brass) makes the room look considered rather than collected-by-accident. Sticking to a single brand for the mixing valves (shower and basin taps) is usually wise because spares and cartridges are easier to source five years down the line.
Brands we stock — including Mira, Hansgrohe, Roca, Ideal Standard, Bristan, Grohe, Triton and RAK Ceramics — all offer cross-compatible ranges. Browse bathroom taps or our full catalogue to compare finishes side-by-side.
Don't skip the small stuff
It's easy to spend the budget on the big items (bath, vanity, toilet) and run out when you get to the things that actually finish the room:
- Waste traps, bottle traps and flexible connectors
- Bath panels for exposed sides
- A suitable bath screen if it's a shower bath
- Silicone sealant, threaded tape, isolation valves
- A toilet seat (often sold separately from the pan)
- A mirror and lighting
Budget roughly 10–15% of the suite cost for these incidentals.
Book the fitter before you buy
Stock and delivery dates are meaningless if your fitter is booked three months out. Talk to your installer first, agree a fit date, then order the suite to arrive a week or so before — enough lead time to check the delivery for damage without the boxes sitting in your hallway for a month.
If you're fitting it yourself, make sure you understand the UK rules around installing bathroom electrics, which fall under Part P of the Building Regulations. Any fixed wiring in a bathroom should be signed off by a qualified electrician.
