A Shower Room Done Right Beneath the Tiles

A shower room is the most demanding small room in a house. It has to be beautiful, it has to work in often tight dimensions, and above all it has to be watertight — because the one thing you cannot see, the waterproofing, is the thing that decides whether the room lasts twenty years or leaks into the ceiling below within two. Get the falls, the drainage, the tanking and the ventilation right and a shower room is a pleasure for decades. Get them wrong and no amount of expensive tiling will save it.

This page is for the shower room, the walk-in shower room, the wet room and the downstairs shower room — designed and built to a fully waterproofed standard. As a design-and-build contractor, we deliver the whole thing under one fixed-price contract: the design, the level-access or walk-in shower, the tanking, the underfloor heating, the sanitaryware and brassware, the tiling and stone, the ventilation and lighting, and the making-good. It is the same standard as our bathroom renovations, focused on the shower.

Shower rooms come in many forms, and we build all of them: a compact downstairs shower room or cloakroom carved from spare space, an en-suite off a bedroom, a generous walk-in shower room as a second bathroom, or a fully open wet room with no tray or screen. Where accessibility matters, a level-access shower room is the ideal solution — our accessible bathrooms page covers that in depth.

The craft is in the invisible work. A wet room only performs if the floor is built up and laid to the correct falls, the whole zone tanked with a proven system, and the room properly ventilated so moisture leaves rather than settling into the structure. These are the steps a cheap job rushes or skips, and exactly where we are meticulous — wet-testing the tanking before and after tiling, and sizing the extraction and underfloor heating to keep the room dry and fresh.

We design and build shower rooms across NW3, NW8, NW1, NW11, N6, W1 and SW London — tight downstairs shower rooms in period terraces, en-suites in lofts and extensions, and luxury walk-in shower rooms and wet rooms in family homes — each tanked, tested and warranted.

Six Kinds of Shower Room

From a tight cloakroom to an open wet room, the right approach depends on the space, the use and your taste. These are the six we build most.

Most Popular

Walk-In Shower Room

A large walk-in shower with a glass screen and a low or flush threshold, alongside a basin and WC. The everyday luxury — easy to use, easy to clean, and a strong alternative to a bath in a second bathroom.

ThresholdLow / flush

Open & Minimal

Level-Access Wet Room

The whole floor tanked, the shower draining through a floor outlet with no tray and no screen — the most minimal and most accessible shower room of all, and the most demanding to build well.

ThresholdNone

Space-Saving

Compact / Downstairs

A small shower room or shower-and-WC carved from spare space — an under-stairs void, a utility corner, a box room. Clever layout and wall-hung fittings make genuinely tight spaces work hard.

En-Suite Shower Room

A private shower room serving a bedroom — in a loft, an extension or a reconfigured layout. Designed to fit the available space elegantly, with the plumbing planned into the wider works.

What a Shower Room Actually Includes

The watertightness lives in the detail. Every element below is delivered, wet-tested and warranted under one fixed-price agreement.

Shower Room Design

A layout that makes the most of the space — shower size and position, fittings, storage and door swing — presented in 3D so you see the finished room before work starts. Especially valuable in compact and awkward spaces.

Walk-In Shower / Enclosure

A walk-in shower with a frameless or steel-framed glass screen, or a wet-room drain with no screen at all — with a quality shower valve and head, thermostatically controlled and built to last.

Full Waterproof Tanking

The wet zone — or the whole floor in a wet room — tanked to BS standards before tiling, with sealed corners, upstands and pipe penetrations. The single most important element, and the one we never compromise.

Drainage & Falls

Floor falls formed correctly to a linear or point drain, sized to the shower output, so water clears cleanly and never pools — the difference between a wet room that works and one that floods the floor.

Underfloor Heating

Electric or hydronic underfloor heating that keeps the floor warm and dries the room quickly after a shower — both a comfort and a defence against the damp and mould that plague cold shower rooms.

Sanitaryware

Wall-hung or floor-standing WC and basin from designer ranges — Duravit, Villeroy & Boch, Catalano — chosen to suit the space and concealed-cistern where it helps a clean, easy-to-clean look.

Brassware

Shower valves, heads and taps to specification — from quality thermostatic mixers to Vola, Dornbracht and Lefroy Brooks — in the finish that ties the room together, anti-scald where needed.

Tiling & Stone

Wall and floor tiling, natural stone or large-format porcelain, laid to a high standard with crisp grout lines, niches and trims — slip-rated on the floor where the shower zone needs it.

Ventilation & Extraction

A properly sized, quiet extractor — often humidity-sensing — ducted to outside, clearing moisture fast. The unglamorous detail that keeps a shower room fresh and mould-free for years.

Lighting & Mirror

IP-rated, dimmable lighting layered for task and ambience, an illuminated demist mirror, and shaver and toothbrush provision — lighting designed for a small, often windowless room.

Plumbing & Electrics

Hot, cold and waste re-routed to the new layout by our plumbers, and NICEIC-certified electrics for lighting, the extractor, underfloor heating and shaver points — all self-certified under Part P.

Snagging & Aftercare

A wet-test of the tanking and drainage, a two-stage snag, a 12-month defects period, a 10-year workmanship warranty and a six-month service visit.

The Six Things That Make a Shower Room Last

A shower room is loved or regretted on these six points — all decided beneath the tiles, before anything looks finished.

i.

Falls & Drainage

The floor laid to the correct gradient so water runs to the drain and never pools — the hidden geometry that decides whether a wet room works or floods.

ii.

Watertight Tanking

The whole wet zone tanked and sealed at every junction before tiling, and wet-tested — the envelope that stops water reaching the structure and the room below.

iii.

Effective Ventilation

A quiet, properly sized extractor that clears moisture fast — without it, even a beautiful shower room grows mould and smells damp within months.

iv.

Layout in a Small Space

Door swing, fittings and shower position resolved so a compact room feels usable, not cramped — the skill that turns an awkward corner into a proper shower room.

v.

Glazing & Light

The right screen — frameless, framed or none — and IP-rated, layered lighting to make a small, often windowless room feel bright and open.

vi.

A Warm, Dry Floor

Underfloor heating keeping the floor warm and drying the room quickly — comfort and a practical defence against damp in a room that gets wet every day.

The Engineering Beneath the Tiles

A shower room is watertight because of what is done before tiling. Here is what is designed and installed.

Falls & Drainage

  • Falls: Shower zone laid to a 1:40–1:80 gradient to a linear or point drain
  • Drain: Low-profile, high-flow wet-room drainage sized to the shower output
  • Substrate: Rigid, deflection-free board or screed to protect the waterproofing and tiles
  • Build-up: Floor lowered or built up as needed for level access

Waterproofing

  • Tanking: Full wet-zone tanking (Schlüter-KERDI, BAL WP1 or equivalent) to BS 8000
  • Junctions: Sealed corners, upstands and pipe penetrations — where leaks usually begin
  • Wet-test: Tested before tiling and again at completion
  • Flooring: Slip-resistance rated for wet barefoot areas in the shower zone

Ventilation & Comfort

  • Extraction: Quiet, humidity-sensing extractor fan ducted to outside, sized to the room
  • Heating: Electric or hydronic underfloor heating, plus a heated towel rail
  • Demist: Demist mirror pads and IP-rated lighting suited to a humid room
  • Glazing: Toughened or laminated glass screens; frameless on premium schemes

Services & Compliance

  • Plumbing: Hot, cold and waste re-routed; thermostatic, anti-scald shower valves
  • Electrics: NICEIC-certified, IP-rated zones to BS 7671, Part P self-certified
  • Drainage: Gravity where possible, macerator or pump where required
  • Building Control: Notified where structural or new drainage work applies
A shower room is the easiest room to make look good and the easiest to get wrong. The tiling is the part you photograph; the tanking and the falls are the part that decide whether you are still happy with it in ten years.

Making a Small Shower Room Work Hard

A downstairs or compact shower room is often the most useful room you can add — and the one that most rewards clever design.

Some of the most valuable shower rooms are the smallest — a downstairs shower-and-WC carved from an under-stairs cupboard, a corner of a utility, or a redundant box room. An extra shower room takes pressure off the main bathroom, adds a facility for guests and works as a future-proof ground-floor option, and it is one of the improvements buyers notice. The challenge is purely spatial, and that is exactly where design earns its keep.

In a tight space, everything is deliberate: a wall-hung WC and basin to free floor area and ease cleaning, a sliding or pivot door that does not foul the fittings, a walk-in or corner shower sized to the room, recessed niches instead of protruding shelves, and large-format tiles with minimal grout lines to make the space feel bigger. Lighting and a demist mirror lift a windowless room, and the drainage and ventilation are planned around the constraints from the outset — a macerator where gravity drainage is not possible, ducted extraction where there is no external wall nearby.

We resolve all of this in the 3D design before any work starts, so you can see how the room works and be confident it will feel usable rather than cramped. For tight bathrooms generally see our small bathroom solutions page, for a ground-floor WC see cloakroom installations, and for an early budget use the cost calculator.

Detailed Answers to the Questions That Matter

What is a shower room, and how is it different from a bathroom or a wet room?

A shower room is a bathroom built around a shower rather than a bath — a walk-in shower or enclosure, a basin and a WC, with no tub. A wet room is a type of shower room where the whole floor is tanked and the shower drains through the floor with no tray or screen. So all wet rooms are shower rooms, but not all shower rooms are wet rooms. We design and build all of them — a compact downstairs shower room, an en-suite, or a fully open level-access wet room.

How much does a shower room cost in London in 2026?

As a guide for London: a compact shower room or downstairs shower room typically runs £8,000–£14,000; a high-quality walk-in shower room £14,000–£24,000; and a full level-access wet room or a larger luxury shower room £20,000–£35,000+. Cost depends on size, whether it is a tanked wet room, the sanitaryware and brassware, and the tiling and stone. Use the cost calculator for an early band, then we firm it up at survey.

How long does a shower room take to install?

A typical shower room takes 2–4 weeks on site, with a level-access wet room at the longer end because of the floor build-up and tanking. Add 2–3 weeks of design and material selection beforehand. We give you a week-by-week programme before starting, and because it is usually a single room, we keep disruption to the rest of the house contained.

Can you fit a walk-in shower or a wet room?

Yes — both are among our most-requested projects. A walk-in shower has a low or flush threshold and a glass screen; a wet room removes the tray and screen entirely, with the floor tanked and laid to falls so it drains through a floor outlet. We build both to a fully waterproofed standard, with the falls, drainage and tanking done properly so they perform and never leak into the room below.

How do you waterproof a shower room, and will it leak?

Waterproofing is the most important part of any shower room, and the part most often skimped. We fully tank the wet zone — or the whole floor in a wet room — with a proven system (such as Schlüter-KERDI or BAL WP1) before tiling, seal all junctions and pipe penetrations, form the floor falls correctly, and wet-test before and after tiling. Done this way it is completely watertight; the leaks people fear come from thin or skipped tanking, which is exactly what we never do.

Can you fit a shower room in a small space or downstairs?

Yes — compact and downstairs shower rooms are a speciality. With clever layout, a wall-hung WC and basin, a sliding or pivot door, and a walk-in or corner shower, we make genuinely small spaces work hard — turning an under-stairs cupboard, a corner of a utility or a redundant box room into a useful shower room or cloakroom. The key is designing the layout and the drainage around the constraints, which we resolve before any work starts.

Do I need ventilation, and how do you stop mould?

Yes — good ventilation is essential, especially in a shower room with no opening window or a compact space. We fit a properly sized, quiet extractor fan (often humidity-sensing) ducted to outside, combined with underfloor heating that keeps surfaces warm and dry. Together these clear moisture quickly and prevent the condensation and mould that plague poorly ventilated shower rooms — the unglamorous detail that keeps the room fresh for years.

Do I need building regulations or planning permission for a shower room?

Planning permission is not normally required for a shower room within the existing house. Building Regulations apply to the electrical work (Part P, which our NICEIC electricians self-certify), to ventilation, to drainage, and to any structural work — for example if a floor is altered for a level-access wet room. Adding a new shower room where there was no plumbing also involves new drainage that must comply. We handle and certify all of this as part of the contract.

Can a shower room be level-access or accessible?

Yes — a level-access wet room is the gold standard for an accessible shower room, with step-free entry, slip-resistant flooring and the option of grab rails and a seat. If accessibility is the priority, our accessible bathrooms page covers it in detail, and we design and build the shower room to suit current and future mobility needs while keeping it looking like a beautiful contemporary room rather than a clinical one.

Will a new shower room add value to my home?

A well-designed shower room — particularly an additional one, such as a downstairs shower room or an extra en-suite — is one of the more reliable improvements for both saleability and value, because the number of bath and shower rooms is something buyers weigh heavily. A walk-in shower or level-access wet room is also increasingly preferred over a bath in second bathrooms. As always, quality of design and waterproofing is what makes it an asset rather than a future problem.
