Service Overview

Bathroom Installation — what's actually involved

What it is

Bathroom installation is the full programme: strip-out, services replumb (hot/cold/waste), electrical first fix (lighting, shaver, extraction), substrate preparation, tanking, tiling, sanitaryware installation, plumbing second fix, lighting, mirror, accessories and snag. We install standard bathrooms, en-suites, wet rooms and accessible bathrooms.

Who it's for

Homeowners refurbishing a single bathroom, en-suite or whole upstairs, landlords replacing tired bathrooms between tenancies, and clients converting a bath into a walk-in shower or wet room for accessibility. We work with sanitaryware from any supplier and can also recommend trusted local merchants.

When you need it

When tiles are loose or grout is failing, when a shower tray is leaking through the ceiling below, when condensation is causing mould (a sign of poor extraction), when the property is being sold, or as part of a wider renovation. A failing bathroom is also the most common cause of insurance claims in residential property — fix it before it floods.

Why professional matters

Bathrooms hide their failures inside walls. A cheap tanking job, an unsealed waste pipe or an under-spec shower tray will leak unseen for months before the ceiling below tells you. Doing it properly the first time — with WRAS-compliant plumbing, manufacturer-spec tanking and continuous extraction — is far cheaper than the insurance claim later.

What happens if it's ignored

The cost of leaving it — or getting it wrong

Leaks through to the ceiling below

The single most common cause of insurance claims. Poor tanking, unsealed wastes and badly bedded trays leak quietly for months. The ceiling damage is the messenger.

Mould from undersized extraction

Building Regs Part F requires 15 litres/sec of extraction. Most failing bathrooms have nothing or an overrun fan venting into the loft. We fit ducted continuous extraction to outside wall.

Tiles that come off the wall in year two

Tiles laid on unprimed plasterboard, with the wrong adhesive, fall off. We prime substrate, use the right adhesive for the tile weight, and back-butter large-format porcelain.

Shower trays that flex and leak

Acrylic trays fitted without proper bedding (sand-and-cement or tray riser kit) flex underfoot and break the silicone seal at the wall — water tracks behind the tiles.

Our Process

A defined system — so you know exactly what happens next

  1. Step 1

    Survey & specification

    Site survey, measured layout drawing, suite and tile specification, services check. Fixed quote with everything listed line-by-line.

  2. Step 2

    Strip-out & services first fix

    Existing bathroom removed, walls and floor opened where needed, hot/cold/waste re-routed in copper or plastic, electrics first-fixed for lighting and extraction.

  3. Step 3

    Substrate & tanking

    Walls in shower zones boarded with cement board (not plasterboard), full tanking applied to manufacturer spec — paint-on membrane to 1.8m above tray and full floor. Photographed and signed off.

  4. Step 4

    Tiling & sanitaryware fit

    Tiles set out so cuts fall in least-visible positions, laid with the right adhesive for size and substrate, grouted and silicone-sealed at internal corners. Suite installed and plumbed in.

  5. Step 5

    Test, snag & handover

    Full water-pressure test, shower run for 30 minutes, all wastes checked for flow, electrical certificate issued. Sealed and snagged with you. 12-month workmanship guarantee, 10-year tanking guarantee.

In Detail

Materials, methods and the situations they suit

Bathrooms are the most failure-prone room in a property because they combine water, electricity and timber framing in a confined space. Below is how we approach the most common bathroom types — and the technical detail that separates a 25-year bathroom from a 5-year one.

Standard family bathroom — bath, shower over, basin, WC

Suite typically by Roca, Ideal Standard, Lecico or Burlington. Bath bedded on bath legs and battened to wall. Bath-screen sealed with neutral-cure silicone. Shower over bath supplied with thermostatic mixer (TMV2) for scald protection. Tiled to ceiling in shower zone, half-height elsewhere or fully tiled per client preference.

Walk-in showers and wet rooms

Wet rooms require a graded substrate (1:80 fall in all directions to the waste), a fully tanked floor and walls to at least 1.8m, and a wet-room drain compatible with the floor build-up. We tank to the manufacturer's data sheet, photograph each stage, and pressure-test before tiling. Tray-based walk-in showers — Lakes, Coram, Aqualux — installed on tray riser kits, with the tray bedded so it cannot flex.

En-suites in tight spaces

En-suites under stairs, in loft conversions and converted box rooms need careful set-out. We compute floor-to-ceiling heights in the shower zone (minimum 2m), check soil-stack run distances for the WC (max 6m per Part H), and design the suite around what physically fits — not what the showroom recommended.

Accessible and wet-room conversions

Bath-to-shower conversions for elderly or mobility-restricted clients — half-height shower seat, level-access tray or graded wet-room floor, grab rails fixed to noggins, slip-resistant flooring. We work with occupational therapists' recommendations where required.

Tile choice — porcelain, ceramic, natural stone

Large-format porcelain (600x1200 and above) needs S2-class adhesive, back-buttered, with a tile-levelling system. Natural stone (marble, travertine, slate) needs sealing before grouting and a sealer top-up annually. We advise on tile selection at the survey — some specs cost an extra day's labour and clients should know up front.
