Shower & bath installation across London
Whether you need a like-for-like electric shower swap on a Tuesday morning, a complete bath-to-shower conversion across the weekend, or a five-ensuite wet room rebuild for an HMO licence renewal, our installers handle the entire job under one roof. Plumbing, electrical, waterproofing, tiling and silicone — one team, one quote, one warranty.
Every installation starts with a 30-second pressure and flow test on the doorstep. Without those two numbers any shower recommendation is a guess — a digital shower needs 1.5 bar minimum per IPS guidance, a mixer needs at least 1.0 bar to BS 6700, and a power shower assumes a pumped 2.0–3.0 bar. The test takes longer to describe than to perform, but it stops the wrong shower being fitted in the wrong system.
The result is a fixed-price quote with the brand, model, kilowatt rating and TMV class written on it. No day rates, no part mark-ups, no surprise add-ons. Most replacements stocked on the van — Mira, Aqualisa, Triton, Bristan and Hansgrohe — so same-day completion is the norm on emergency calls.

Shower types we install
Four broad categories cover almost every London install. The right one for your property depends on your boiler type (combi, system, regular), incoming mains pressure, household size and how many outlets you want running at once.
Electric shower
8.5 kW – 10.5 kWHeats water on demand from the cold mains. Independent of the boiler so it still works if the heating is off. Needs a dedicated 32 A or 40 A radial circuit, a Part P notifiable installation and at minimum 1.0 bar of incoming mains pressure. Best for: small flats, second bathrooms, properties on a regular boiler with poor hot-water pressure.
Thermostatic mixer shower
BS EN 1287 / TMV3Blends hot and cold from the existing system. Pulls hot from a combi or unvented cylinder. Anti-scald TMV3 cartridge locks at 38 °C and shuts down within 2 seconds if the cold supply fails. Best for: combi-boiler homes, en-suites, family bathrooms where temperature stability matters.
Digital / smart shower
1.5 bar minimum (IPS)Separate control panel and power box. Wireless temperature presets, app control, multiple outlets (head plus body jets plus bath filler). Requires the IPS 1.5 bar minimum pressure and a 13 A fused spur. Best for: high-spec en-suites, rental flips that need a wow factor, customers who want phone-controlled showers.
Power shower (pumped)
2.0 – 3.0 bar twin-impellerMixer with a built-in or remote twin-impeller pump for properties on a gravity system (cold tank in the loft, hot tank in the airing cupboard). The pump pulls both hot and cold from the tanks and pushes them through the shower. Best for: older terraced houses, regular-boiler conversions where mains pressure is too low for a mixer.
Bath replacement & conversions
Bath work splits three ways: like-for-like swap (the old bath out, a new one of the same size in), bath-to-shower conversion (bath out, walk-in shower in) and full wet room (no tray, no enclosure, the whole floor tanked). Each is priced differently and each has a different working schedule.
Like-for-like bath replacement is one full day on site at £450–£850. The new bath supplied (standard 1700 × 700 acrylic or steel), the old one removed and disposed, panel refitted, fresh silicone to ISO 11600 Class F-25-LM mould-resistant and a leak test on the waste before we leave. Upgrade to a Carron steel enamel bath or a freestanding tub and the unit price changes but the labour stays the same.
Bath-to-shower conversion is 3–4 working days, £2,400–£4,800. The bath comes out, the wall tile is stripped to the splash zone, a low-profile 1200 × 800 stone-resin tray or up-stand is set, the 40 mm waste run is dropped into the soil stack, a TMV3 thermostatic mixer is fitted, the walls are retiled in your choice of porcelain or ceramic and an 8 mm safety-glass walk-in screen is installed. Skip and waste removal are included.
Full wet room is the most involved — 5–7 days, £3,500–£6,500. The whole floor is dropped, formed-fall ply substrate goes in, BS 8000-4 tanking membrane covers floor and walls to 1800 mm, a linear drain runs to a 40 mm waste with a 1:80 fall, tile is laid on a flexible adhesive, all silicone seams are flush. The 24-hour ponded water test is filmed on site before any tile goes down.
How it works — start to finish
Five steps from first phone call to handover. Most replacements close inside a week, larger conversions on a two-to-three-week programme.
Pressure & flow survey
15 minOn the doorstep we measure incoming cold mains pressure with a calibrated gauge and run a 30-second bucket test for flow. Without these numbers any shower recommendation is a guess. The result is written on the quote.
Specification & fixed quote
Same dayBased on system type (combi / regular / unvented), pressure and your usage we recommend the right shower category and brand. Fixed price confirmed before the engineer leaves — no day rates, no surprises.
Booking & parts order
24–72 hrMost replacements are stocked on the van for next-day fit. Special-order units (digital, designer brassware) come on a 48–72 hour lead time. Wet rooms and bath conversions are booked on a date that suits the household.
Install day
2 hr – 4 dayElectric shower swap is 2–3 hours. Mixer install is half a day. Bath replacement is one full day. Bath-to-shower conversion is 3–4 days including tiling. Full wet room conversion is 5–7 days.
Test, certify, walk-through
30 minPressure test on the joints, leak test on the tray, TMV calibration on the mixer, RCD trip test on electric installs. Part P certificate issued where required, 2-year workmanship warranty card handed over.
Standards we work to
Shower and bath installation in London is governed by a stack of British Standards and Building Regulations. Some are legal duties (Part P, BS 7671), some are industry minimums (BS 6700, IPS pressure thresholds), all of them get cited on the certificate.
Water supply systems
Design, installation, testing and maintenance of services supplying water for domestic use within buildings. Every mixer, digital and power shower install on a London property is sized against BS 6700 minimum flow and pressure requirements before the order is placed.
Pressure flushing valves
European standard for sanitary tapware — covers durability, watertightness and acoustic behaviour of pressure flushing devices. All bath-fill valves and concealed brassware we fit meet EN 12541 to keep noise transmission low in flats and HMOs.
Thermostatic mixing valves (low pressure)
Performance requirements and test methods for low-pressure TMVs. Every shower mixer on a vulnerable-occupant property (HMO, care, family bathroom) is fitted with a TMV2 or TMV3 cartridge to this standard, set to 38 °C.
Digital shower pressure threshold
Industry standard minimum dynamic pressure for a digital shower install. Below 1.5 bar a pump is required. We measure on the doorstep — if your incoming mains is below 1.5 bar we will quote a Salamander or Stuart Turner pump in the same job.
Supplementary equipotential bonding
18th Edition wiring regs requirement for supplementary earth bonds in bathrooms. Every shower or bath install where the existing bond is missing or undersized gets corrected and certified in the same visit. Non-negotiable on rented property.
Electrical work in dwellings
Notifiable electrical work — installing or replacing an electric shower circuit, fitting a shower pump on a dedicated circuit — is notified to the local authority by our NICEIC registered electrician. Compliance certificate issued on completion.
Workmanship on building sites — waterproofing
Tanking and waterproofing workmanship standard for wet rooms. Membrane is BS 8000-4 compliant, tested with a 24-hour ponded water test on the formed fall before any tile goes down.
