Walk-in shower installation in Bromley starts with your hot water system: a combi boiler suits a thermostatic mixer, a gravity-fed tank often needs a pump, and an unvented cylinder handles a rainfall head. A vetted local fitter checks the pressure, chooses the right shower and tray, tanks the shower area and quotes in writing, free through our referral.
Which Shower Suits Your Bromley Home’s Water System?
The hot water system decides the shower. A combi boiler heats mains water on demand and suits a thermostatic mixer or an electric shower, but not a power shower. A gravity-fed system with a loft tank gives weak pressure upstairs and often needs a pump. An unvented cylinder delivers mains pressure everywhere and suits high-flow mixers and rainfall heads.
| Your system | How to tell | Shower that suits | Avoid |
|---|---|---|---|
| Combi boiler | Wall boiler, no hot water cylinder or loft tank | Thermostatic mixer, or electric shower | Power shower (needs a cylinder to pump from) |
| Gravity-fed | Cold tank in the loft, hot cylinder in an airing cupboard | Mixer with a shower pump, or a power shower | High-flow rainfall head without a pump |
| Unvented cylinder | Sealed cylinder, no loft tank, strong pressure at every tap | Thermostatic mixer, rainfall head, body jets | Little to avoid; check the cylinder size for two showers |
| Electric supply only | No hot water reaching the bathroom at useful pressure | Electric shower fed from the mains | Anything needing stored hot water |
A quick diagnostic: if every tap in the house is weak, the mains supply or a shared pipe is the limit. If only the shower is weak, the head or valve is probably scaled up, which in Bromley’s hard water is common.
Walk-In Shower, Enclosure or Wet Room in Bromley?
A walk-in shower uses a low-profile or level tray with a single glass screen and an open entry, so there’s no door to step through. An enclosure adds doors and contains water more fully. A wet room does away with the tray and tanks the whole floor. Walk-in showers suit most refits and bath to shower conversions; wet rooms suit level access.
| Option | Access | Water containment | Time on site |
|---|---|---|---|
| Walk-in shower with low tray | Low step or flush with a level-access tray | Good with a wide screen and correct head position | About 1 to 3 days |
| Shower enclosure | Step over the tray edge | Best | About 1 to 2 days |
| Wet room | Fully level | Depends on the fall and screen | About 4 to 7 days |
For a full wet room see wet rooms. For replacing the bath entirely, see bath to shower conversion.
Shower Installation in Bromley, Step by Step
A new shower installation runs in a set order: check the system and pressure, remove the old shower or bath, fit the tray and pipework, tank the shower walls, tile, fit the screen and valve, then test for leaks and temperature. A like-for-like swap takes a day; a walk-in shower in a bath’s place takes one to three days.
- Survey: confirm the water system, measure pressure, check the waste route and the wall behind the shower.
- Strip-out: old shower, tray or bath removed; walls checked for damp.
- First fix: new pipework and, for electric showers, a dedicated circuit run by a registered electrician. The plumbing for a rainfall shower or shower enclosures is set at this stage.
- Tray and waste: low-profile tray levelled and sealed, waste connected with a proper fall.
- Tanking and boarding: cement board and a waterproof membrane on the shower walls.
- Tiling: walls tiled and grouted, silicone at every joint and around the tray.
- Fit-out and testing: screen, valve and head fitted; the valve tested for temperature and the tray flood-tested.

Water Pressure, Older Homes and Hard Water Across the Borough
Pressure problems cluster in older Bromley properties. Interwar semis make up about 30% of the borough’s homes and Victorian houses another sixth, and many still run gravity-fed systems with a loft tank, which means weak pressure at an upstairs shower. Lead or galvanised supply pipes in Victorian terraces restrict flow further. A refit is the moment to fix both.
- Interwar semis in West Wickham, Petts Wood and Hayes: often gravity-fed. A shower pump, or a move to a combi or unvented cylinder, transforms the shower.
- Victorian houses in Penge and Beckenham: old supply pipes worth replacing while the wall is open.
- Flats in Bromley town: shared supplies can limit pressure; an electric shower may be the reliable choice.
- Larger homes in Chislehurst and Bickley: check the cylinder can serve two showers at once.
Bromley’s water is hard, so shower heads, valves and glass scale up quickly. Choose a valve with an accessible cartridge, a head that’s easy to descale and glass with a protective coating, and consider a softener if the pipework is being renewed.
Does Removing the Bath for a Walk-In Shower Affect Resale?
It can, in a home with only one bathroom. A survey of estate agents by a bathroom retailer found most thought removing the only bath could reduce a property’s value by a few percent and slow the sale, because families want a bath. In a second bathroom or an en-suite, a walk-in shower is generally safe and often preferred.
The practical rule is to keep a bath somewhere in a family home and put the walk-in shower where it’s used most. If you’re staying long term and the bath is never used, comfort and safety come first.
Regulations for Shower Installation in the London Borough of Bromley
An electric shower needs its own circuit and any electrical work in a room with a shower is notifiable under Part P, so a registered electrician must do or certify it. New fittings must meet the Water Supply (Water Fittings) Regulations 1999, and a thermostatic valve should protect against scalding. External vents in conservation areas may need consent.
- Part P: electric showers, pumps, lighting and fans in the bathroom zones are notifiable. GOV.UK: building regulations approval
- Water regulations: fittings must be watertight, suitable and installed without risk of backflow. Water Supply (Water Fittings) Regulations 1999
- Scald protection: Approved Document G limits bath water to 48°C; a thermostatic mixer gives the same protection at the shower. Approved Document G
- Conservation areas: Bromley has 47; a new vent or pipe on a street-facing wall may need consent.
Comparing Shower Installation Quotes in Bromley
Compare shower quotes on what’s behind the tiles and what’s checked. Each should name the shower type and valve, the tray, the tanking system, who does the electrics, whether a pump or pipe replacement is included, and how the installation is tested. A quote that doesn’t mention your water system hasn’t looked at the real problem.
- Has the fitter measured the pressure and confirmed the shower suits the system?
- Tray type, screen size and tanking behind the shower walls
- Electric shower or pump: who does the circuit and certifies it?
- Old pipework: replaced or reused?
- Testing: temperature control and a flood test of the tray
- Workmanship guarantee, in writing

Shower Installation Questions from Bromley Homeowners
Can I have a power shower with a combi boiler?
No. A power shower pumps from a stored hot water cylinder, which a combi doesn’t have. A thermostatic mixer or an electric shower is the right choice with a combi.
Why is my upstairs shower weak?
Most often because the house is gravity-fed and the loft tank sits too close to the shower height to give pressure. A shower pump or a change to a mains-pressure system fixes it.
How long does a walk-in shower take to install?
One to three days for a walk-in shower replacing a bath or an old enclosure, plus curing time for tanking and silicone. A wet room takes longer.
What are the benefits of a walk-in shower?
No door to clean, an easier step in and out, more usable floor space than a bath, and a layout that can be made level for later mobility needs. With the right valve for your system, it’s also a better shower than most bath-shower combinations. Pair it with slip-rated flooring.
Do I need an electrician for an electric shower?
Yes. An electric shower needs its own circuit and the work is notifiable, so a registered electrician must install or certify it and give you a certificate.
