Shower Installation Costs UK — What to Charge to Fit a Shower in 2026

Shower Types and What Each Install Involves

Before you can price anything, you need to know which type of shower you're fitting and how the customer's plumbing is set up. The valve type, the water supply and whether a pump is involved all change the scope. Here are the main types you'll be quoting in UK homes.

Electric Showers

An electric shower heats cold mains water on demand using a built-in element, so it only needs a cold feed and a dedicated electrical supply. It works independently of the boiler and hot water cylinder, which makes it popular for second bathrooms, en-suites and homes with poor hot water pressure. The trade-off is flow rate — an 8.5kW unit delivers a modest spray, and customers chasing a powerful shower are often disappointed unless you fit a 9.5kW or 10.5kW model on an upgraded circuit.

The plumbing side is straightforward for a like-for-like replacement. The electrical side is not: an electric shower needs its own correctly-rated circuit, the right cable size for the kW rating and cable run, RCD protection, and an isolation switch. This is notifiable work under Part P of the Building Regulations and should be done by a qualified electrician — never wire one into a ring final or an undersized circuit.

• Like-for-like swap (existing circuit sound): £150–£300 labour
• New electric shower with new circuit (plumber + electrician): £350–£650 total
• Consumer unit upgrade if board can't take the load: £400–£900 extra

Mixer Showers

A mixer shower blends stored hot and cold water through a single valve. It needs both a hot and cold supply and relies on the home's existing water heating, so it suits combi-boiler and cylinder systems alike. Output depends entirely on the available pressure — great on a strong combi or a pumped system, weak on a low-pressure gravity-fed setup unless a pump is added.

A surface-mounted (exposed) mixer is the quickest to fit because the pipework and valve body sit on the wall. A concealed mixer is buried in the wall for a clean look but means chasing out tile and plaster, which adds labour and ties the job to tiling and making-good. Always price exposed and concealed as separate options.

• Exposed mixer onto existing supplies: £200–£400 labour
• Concealed mixer (chasing + making-good, excl. tiling): £350–£600 labour

Thermostatic Bar and Concealed Valve Showers

A thermostatic valve holds the temperature steady when someone runs a tap or flushes a loo elsewhere in the house, and shuts off if the cold supply fails — a safety feature that's now the default ask. Thermostatic comes as a bar valve (mounted across two inlets on the wall) or a concealed valve plumbed behind the tiles, often paired with a fixed drencher head and a handset on a riser.

The bar valve is the easy upgrade from a worn mixer. The concealed thermostatic install is a bathroom-fitter job: pipework set into the wall, a recessed valve box, often a separate diverter for the drencher and handset, then tiling over the top. Get the rough-in depth right before the tiler starts — a valve set too deep or too proud is an expensive redo.

• Thermostatic bar valve swap: £200–£400 labour
• Concealed thermostatic valve (excl. tiling): £400–£700 labour

Digital Showers

A digital shower uses an electronic control to set temperature and flow, with the mixing unit sited remotely — in the loft, an airing cupboard or under the bath. The wall control can be wired or wireless, and some allow start-from-your-phone or preset temperatures. They suit high-end bathrooms and customers who want a precise, repeatable shower experience.

Installation is more involved because of the remote processor unit, its low-voltage control wiring and the need for a suitable position with access for servicing. Pumped digital units also need a power supply at the processor. Budget more labour and confirm the unit is matched to the water system (high pressure vs gravity, pumped or not) before you order it.

• Digital shower install (excl. tiling and unit): £350–£700 labour

Power Showers (Built-in Pump)

A power shower is a mixer with an integrated pump, designed for gravity-fed (tank and cylinder) systems where pressure is too low for a decent flow. It boosts both the hot and cold to give a strong spray. Crucially, power showers are not for use on mains-pressure combi or unvented systems — fitting one there is a common and avoidable mistake.

Where the customer has a separate mixer and wants more pressure, an alternative is to leave the valve and fit a standalone shower pump (single or twin impeller) on the supplies. Either way, confirm the cold storage and hot cylinder can feed the pump, and that there's a power supply nearby.

• Power shower unit fit (gravity system): £250–£450 labour
• Separate shower pump added to existing mixer: £200–£400 labour

Like-for-Like Swap vs New Install vs Moving the Plumbing

The single biggest driver of your quote is how much you have to change. Customers rarely understand this distinction, so spell it out in the quote.

• Like-for-like swap: Same shower type, same position, supplies already in place. Quick, low-risk, mostly labour. This is your £150–£400 job.
• New install onto existing supplies: A different valve type or a first shower over an existing bath, using nearby hot and cold feeds with minor pipework. Mid-range — £250–£600 plus fittings.
• Moving or adding plumbing: New pipe runs, relocating the shower, adding a feed where none exists, or chasing concealed pipework into walls. This is where time and cost climb — half a day to several days depending on access and making-good.

Always inspect before quoting. A "simple swap" can hide seized valves, corroded compression joints, undersized supplies or a soldered-in old unit that turns a one-hour job into half a day.

The Electrics for an Electric Shower

Electric showers are high-load appliances and the wiring is the part most likely to bite you. An electric shower must have its own dedicated radial circuit from the consumer unit, protected by an appropriately rated MCB and an RCD (or RCBO). The cable size has to suit the kW rating and the length of the run — a 10.5kW unit on a long cable run may need 10mm² cable rather than 6mm². A pull-cord or surface isolation switch is fitted so the unit can be isolated.

This is notifiable work under Part P in England and Wales — it has to be either carried out by a registered competent person (a Part P electrician) or signed off by Building Control. As a plumber, do the water side and bring in a qualified electrician for the circuit; don't reuse an old, undersized cable just because a shower was there before. If the consumer unit is full or lacks RCD protection, factor in a board upgrade.

Enclosure, Tray and Waste

When the job includes the shower space itself — not just the valve — the enclosure, tray and waste add a substantial chunk of cost and time. The tray has to be set dead level, properly bedded (often on a mortar bed or adjustable feet), and sealed to the waste with the right fall to drain. Get the waste and trap connection right under the tray before you commit, especially on a solid floor where access later is brutal.

Enclosure type drives both price and fitting time: a quadrant or square enclosure with a tray is quicker than a frameless walk-in panel that has to be perfectly plumb. Low-profile and wet-floor (tiled-tray) options look great but need careful waterproofing and falls.

• Tray + waste fit (excl. tray): £150–£350 labour
• Enclosure fit (quadrant/square, excl. unit): £200–£400 labour
• Full enclosure + tray + waste + plumbing in: £600–£1,500 total (plus tiling)

Tiling and Tanking — Often the Biggest Cost

On most shower jobs that touch the walls, tiling and waterproofing are the largest single line — frequently more than the shower unit and its fitting combined. The shower area must be tanked (waterproofed) behind the tiles: a tanking membrane or kit over the boards, sealed into the tray, with extra attention at corners, the valve penetration and the tray-to-wall junction. Skip the tanking and you get water ingress, blown plaster and a callback.

Tiling labour is typically charged per m² and varies with tile size, format and prep. Large-format and patterned tiles, mosaics and natural stone all push the rate up. Tanking is usually priced as a separate item or built into the tiling rate — make sure it's in the quote either way.

• Tiling labour: £40–£70/m² (higher for large-format, mosaic or stone)
• Tanking / waterproofing a shower area: £150–£400
• Tile backer board / overboarding before tiling: £100–£300

Removing a Bath to Fit a Walk-in Shower

Bath-to-shower conversions are one of the most common and most profitable jobs — popular with older customers and anyone wanting easier access. The scope is bigger than a straight shower swap: rip out the bath, cap or reroute the old taps and waste, adapt the supplies for the new valve, fit a tray or form a wet floor, build and tile the walls, then fit the enclosure and screen.

Price it as a project, not a single line. Allow for waste removal, possible floor and wall repairs once the bath is out, and the near-certainty that you'll find something behind the old panel that needs attention. Most conversions land between £1,500 and £3,500 all in, depending on enclosure quality, tiling area and whether it's a tray or a tiled wet floor.

Water Pressure: Combi vs Gravity, and Pumps

Matching the shower to the water system is the number-one thing to check before you quote or order. Fit the wrong type and the customer gets a dribble or a fault — and it comes back on you.

• Combi boiler: Mains pressure hot and cold. Suits mixer and thermostatic showers; do not fit a power shower or pump to a combi.
• Unvented cylinder (mains pressure): Strong, balanced pressure — ideal for thermostatic and digital showers; no pump needed.
• Gravity-fed (tank and cylinder): Low pressure, especially with little head between the tank and the shower. Suits power showers, or fit a separate pump to a mixer to boost flow.
• Electric shower: Runs off cold mains only, so it's a useful answer where hot water pressure is poor — but flow is limited by the kW rating.

Check static and dynamic pressure on site if you're unsure. A reading takes minutes and saves you ordering a unit that won't perform.

What Affects the Quote

Two shower jobs of the same type can differ by hundreds of pounds. The main factors to weigh before you commit a price:

• Tiling area: Usually the biggest variable. More wall to tile and tank means more labour and materials.
• Moving pipework: Relocating or adding supplies, chasing into walls and making-good all add time.
• Access: Solid floors, awkward valve positions, tight spaces and upstairs bathrooms with no easy waste route all slow the job.
• Electrics: A new circuit, cable upgrade or full consumer unit can add several hundred pounds on an electric shower.
• Tile and fittings quality: Large-format, stone or mosaic tiles and premium valves take longer and carry more risk than budget options.
• Making-good and waste: Plastering, decorating around the work and skip or tip charges for the old bath, tray and rubble.

Build these into a line-by-line quote rather than one lump sum. It protects your margin when the customer changes the tile choice, and it shows them exactly what they're paying for.
