Shower Types

4 Types of Shower -- Which One Do You Need?

The right shower depends on your boiler type, water pressure and how much you want to spend. Use the combi boiler compatibility note on each card -- 65% of London homes have a combi.

Electric Shower

What Works with a Combi Boiler?

65% of London homes have combi boilers. Before choosing a shower type, check which options are compatible.

YES

Combi + mixer shower

Works well. Mains pressure (3-4 bar) is more than adequate for most London properties.

YES

Combi + thermostatic mixer

Best option -- thermostatic valve compensates for any pressure fluctuations. Most popular choice for London bathrooms.

Combi + power shower

Combi boilers have no stored water for the pump to draw on. Flow will be inadequate and you risk damaging the boiler.

YES

Combi + electric shower

Completely independent -- heats cold mains water itself. Works even if your boiler is broken. Most popular choice in London flats.

YES

Combi + digital shower

Works fine. Check the manufacturer minimum pressure requirement -- most need 0.5-1 bar, which London mains delivers easily.

What Happens on the Day

How Shower Installation Works -- Step by Step

A typical new shower enclosure installation in an existing bathroom takes 2 days. Here is what each stage involves.

Day 1 -- Plumber

Run hot and cold supply pipes to the shower position
Fit waste and trap; connect to drain or soil stack
Fit shower tray or prepare wetroom former if applicable

Day 1 -- Electrician (electric shower only)

Run a dedicated radial circuit from the consumer unit
Fit double-pole isolator outside the shower zone
Connect supply to the shower unit; test and sign off (Part P certificate)

Day 2

Tile or waterproof the shower area if this is a new installation
Apply tanking membrane if wetroom (must cure before tiling)
Fit shower tray or wetroom former; silicon seal perimeter

Day 2-3 -- Finishing

Fit shower valve, riser rail and head
Connect all water supplies; test for leaks
Final silicon seal at all junctions; clean-up and handover

London Context

London-Specific Factors Before You Book

Water pressure (3-4 bar on Thames Water mains)

Most London zones receive 3-4 bar mains pressure -- more than sufficient for thermostatic mixer showers (which need a minimum of 1 bar). This is why mixer showers perform well in London without a pump.

Hard water (300 mg/l calcium carbonate)

London's water is among the hardest in England. Limescale blocks shower heads, clogs cartridges and reduces flow within 12-18 months. Fit a scale inhibitor on the cold feed to the shower -- a 30-50 inline unit that prevents the bulk of limescale deposition. Clean or replace shower heads annually.

Leasehold flats (majority of London housing)

If you rent your flat on a leasehold, check the lease before making structural changes. Moving the shower to a new position -- especially if it involves cutting a new waste run through a concrete floor -- may require freeholder written approval. Budget 4-8 weeks for this if needed.

Conservation areas and listed buildings

Changes to listed buildings require listed building consent even for internal plumbing work. If your property is in a conservation area, external alterations (e.g. a new vent pipe) may need planning permission. Check with your local council before work starts.

Replacement Guide

Replacing an Existing Shower vs a New Installation

The biggest cost driver is whether you are staying in the same position or moving the shower to a new location.

Scenario	Typical time	Approximate cost
Like-for-like swap (same position, same type)	2-4 hours	£150-350
New position (moving supply pipes)	1-2 days	£400-800 + tiling
Over-bath to separate enclosure	2-4 days	£800-2,000

Moving pipes to a new position adds plumbing time and usually requires making good the original pipework location. Always clarify this with your plumber before booking.

Shower Questions

Frequently Asked Questions

How much does it cost to install a shower in London?

A standard shower installation in London costs between 400 and 1,200 fitted, depending on type and complexity. A like-for-like electric shower swap costs 200-400. A new thermostatic mixer shower over a bath costs 400-800. A full new shower enclosure with tiling costs 800-2,000. A wetroom conversion costs 2,000-5,000. London labour rates (plumber 250-400 per day, electrician 150-300 for an electric shower circuit) are higher than the UK average.

How long does shower installation take?

A like-for-like shower swap (same position, same type) takes 2-4 hours. A new shower over an existing bath takes half a day to one day. A new separate enclosure in an existing bathroom takes 1-2 days (plumbing + tiling). A full wetroom conversion takes 3-5 days including waterproofing, screeding and tiling.

Do I need a plumber or an electrician to fit a shower?

It depends on the shower type. A mixer or thermostatic shower only needs a plumber -- it runs from your hot and cold supply with no dedicated electrical work. An electric shower needs both a plumber (to connect the cold mains feed) and a Part P-registered electrician (to run a dedicated circuit from the consumer unit and fit an isolator switch). Digital showers typically need a plumber for water connections and an electrician for the power supply.

Can a shower be installed anywhere in the bathroom?

In principle yes, but the practicalities vary. The shower must be within reasonable distance of hot and cold supply pipes and a waste drain. Moving these adds cost and time (typically an extra half to full day of plumbing). In leasehold flats, structural changes -- including cutting new waste runs through concrete floors -- may require freeholder approval. In listed buildings, even internal plumbing changes may need listed building consent.

What type of shower is best for a London home with a combi boiler?

The two best options for a combi boiler are a thermostatic mixer shower or an electric shower. A thermostatic mixer blends hot and cold supply directly from your combi -- no stored water needed, and London mains pressure (3-4 bar) is more than adequate. An electric shower is completely independent of the boiler and heats cold mains water itself -- it works even during a boiler breakdown. Avoid power showers with a combi: they require a stored hot water cylinder that combi boilers don't have.
