Shower Installation in London: Cost Guide for Every Shower Type

Shower Installation Costs in London: An Overview

Shower installation in London spans an enormous price range depending on the shower type, the complexity of the installation, and whether additional works such as tiling, new waste runs, or electrical circuit work are included. Understanding what drives the cost variation helps you choose the right shower type for your property and budget, and ensures you can evaluate quotes accurately rather than comparing figures that do not cover the same scope of work.

Electric Shower: £300 to £600 Supply and Fit

An electric shower heats water instantly from the cold mains supply — it does not require a hot water supply, making it suitable for properties where the boiler or hot water cylinder is unreliable, or where a separate shower circuit is needed in a bathroom served only by cold water. Electric shower units cost between £80 and £300 depending on the kilowatt rating and brand. A higher kilowatt rating (9.5 kW or 10.8 kW) delivers a better flow rate and temperature performance but requires a larger circuit cable and a higher-rated circuit breaker.

Installation must be carried out by or notified by a competent person registered with a Competent Person Scheme under Part P of the Building Regulations, as the work involves a new dedicated electrical circuit in a bathroom zone. The total supply and fit cost for an electric shower in London, including the unit, a dedicated 40 amp circuit from the consumer unit, and basic connection, typically falls between £300 and £600. Where the consumer unit is in a remote location — common in London flats where the fuseboard is in a hallway or utility cupboard — cable routing can add to the cost.

Mixer Shower Over a Bath: £200 to £400

A bar mixer shower fitted over an existing bath is the most cost-effective shower addition. It takes hot and cold supplies from the bath taps, blends them to the set temperature, and delivers water through a fixed head or flexible hose. There is no requirement for new electrical work unless a pump is added. Supply and fit cost for a quality thermostatic bar mixer over a bath in London falls between £200 and £400 for a straightforward installation where the plumbing is accessible.

Thermostatic Bar Shower (Concealed or Exposed): £400 to £800

A thermostatic bar valve maintains a consistent outlet temperature regardless of pressure fluctuations elsewhere in the system — particularly valuable in London properties with combi boilers where pressure varies when other outlets are used. Exposed thermostatic bar valves are surface-mounted with visible pipework; concealed valves are built into the wall with only the controls and outlet visible. Concealed installations require a chase in the wall for the valve body and create a cleaner finish but add labour and plastering cost. Supply and fit for an exposed thermostatic bar valve with a fixed head and riser rail falls between £400 and £800 in London.

Power Shower: £500 to £900

A power shower incorporates a pump that boosts flow rate and pressure from a gravity-fed hot water tank system. This makes it suitable for properties with a hot water cylinder and a cold water tank in the loft — common in London Victorian terraces and conversions with older heating systems. Power showers do not work with combi boilers because the boiler already pressurises the hot water: adding a power shower pump to a combi system will not improve the shower and can damage the boiler. A power shower in a suitable property costs between £500 and £900 supply and fit.

Digital Shower: £800 to £2,000+

Digital shower systems operate through an electronic controller that communicates with a remote processor unit, which blends hot and cold water to the set temperature before delivery. The interface at the wall is a touch-panel or dial controller, the processor unit is concealed in a void or cupboard, and the outlet can be a single head, a body jet array, or a rainfall head. Digital showers deliver excellent temperature precision and allow for personalised pre-sets. Supply and fit in London falls between £800 and £2,000 depending on the brand, the complexity of the output configuration, and the accessibility of the processor unit location.

Walk-In Enclosure with Tray: £1,000 to £2,500 Fully Fitted

A walk-in enclosure with a shower tray and frameless or semi-frameless glass screen is one of the most popular choices for London bathroom renovations, combining a premium look with a more straightforward installation than a wet room. Supply and fit cost — including the tray, waste, thermostatic bar valve, fixed head, and glass screen but excluding tiling — falls between £1,000 and £2,500 in London depending on the size and quality of the components.

Wet Room Conversion: £2,500 to £5,000+

A full wet room conversion requires tanking the floor and lower walls, screeding a gradient to the drain, installing a floor drain, and tiling with anti-slip rated tiles. It is the most involved shower installation and carries the highest cost in London. The range of £2,500 to £5,000 covers a standard bathroom footprint; larger rooms or installations requiring complex drainage routing in upper-floor flats will exceed this.

What Is Included in a Quote — and What Is Not

Always confirm what a shower installation quote includes before accepting it. Standard quotes typically cover the valve, the head and handset, waste connection to an existing trap, and basic fitting labour. They often exclude: tiling or retiling around the new shower position, replacement of the shower screen if different from the existing, a new waste run if the drainage cannot connect to the existing trap position, and Part P electrical notification where required. Asking for an itemised quote rather than a lump sum makes it far easier to compare proposals from different contractors and to understand exactly what you are agreeing to.
