Fully tanked walk-in wet rooms with formed floor falls, level-access showering and 25-year waterproof guarantees — designed for accessibility, contemporary style, and zero compromise on long-term reliability.
Tanked to manufacturer spec · Accessibility-ready · 25-yr waterproof system
A wet room is a fully waterproofed (tanked) shower space without a tray, with the whole floor falling to a linear or central drain. Walls are tanked to a minimum 1800 mm, floor is fully tanked, and a glass screen optionally divides the wet zone from the dry zone.
Homeowners wanting a contemporary, open showering space; families future-proofing for ageing in place; anyone with mobility needs (wheelchair access, walk-in showering); Disabled Facilities Grant (DFG) applicants; and landlords improving accessibility on rental stock.
During a full bathroom refurbishment, when converting a bath-only room into a shower room, when adapting a property for mobility needs, or when remodelling for resale appeal in modern-design markets.
Wet rooms look simple — they aren't. The waterproofing system underneath is what determines whether the floor below stays dry for 25 years or whether the kitchen ceiling stains in 18 months. Greencore's wet rooms use the same fully bonded tanking we use in commercial work — there is no shortcut.
A failed wet room is a catastrophic failure. The downstream damage routinely exceeds the original install cost. Here's what goes wrong:
Inadequate tanking, poor drain detail, untaped corners. The leak doesn't show for months — by then, joists and ceilings are wrecked.
Standing water in the corners of the room means slip risk, smell, and accelerated grout failure. Falls must be formed at first-fix, not corrected with grout depth.
A 50 mm bottle trap can't keep up with a high-flow rain shower. Water backs up and pools. We always size and locate drains around real shower flow.
If walls aren't tanked to at least 1800 mm, splash above the tanked line wicks into plasterboard. Mould, blister, ruin.
DFG-funded wet rooms must meet specific dimensions, drainage, threshold and grab-rail requirements. Non-compliant work gets rejected and unpaid.
Water travels. A real wet room tanks the entire floor and walls to head height in the shower.
Falls cut into floor by hand are uneven. We use manufacturer pre-formed gradient boards (Aqua-I, Wedi, Schluter Kerdi) for guaranteed falls.
Drain quality matters. We fit Easy Drain, Schluter Kerdi-Line or McAlpine — never £30 generic units. The drain is the single most-used component in the room.
We check joist directions, floor depths, drainage routes, soil-stack proximity and ceiling clearance below. Some homes need a slight floor build-up; we'll tell you upfront.
Drain location, fall direction, wall tile layout, glass screen, vanity, WC, lighting and accessibility features all visualised in 3D before any work begins.
Itemised fixed-price quote. Lead-time confirmed. DFG paperwork if applicable handled by us.
Strip-out, joist alteration if needed, drainage, pre-formed gradient floor, marine-grade tile backer walls, fully bonded tanking, electrics, ventilation, tiling, glass screen, fixtures, controls.
24-hour flood test before tile. After completion: flow test of drain, water pressure test, electrical compliance certificate, owner walk-through, 25-year tanking warranty registered.
No step, no tray, no obstacle — safer for everyone and essential for mobility users.
Glass, tile, linear drains and minimal hardware deliver a hotel-spec finish that ages beautifully.
No tray, no enclosure tracks, no silicone reservoirs — a single floor that mops in seconds.
Most clients in their 50s install with grab-rail back-grounds and a fold-down seat hidden behind a panel — invisible today, ready when needed.
We undertake DFG-funded work to council specification, including the paperwork.
Manufacturer-backed waterproof system warranty. The single most important number on any wet-room quote.
Wet rooms are the highest-stakes plumbing install in a home. Here's the technical detail behind a Greencore wet room:
Wedi Fundo, Schluter Kerdi-Line, Aqua-I or Mapelastic depending on substrate. Always a fully bonded membrane (paint-on or sheet) covering the entire floor and walls to 1800 mm minimum in the shower zone, 1200 mm in splash zones, with reinforced corners and pipe-collars at every penetration.
On timber floors, joist-supported pre-formed gradient boards (typically 1:50 falls into a linear or 4-way central drain). On concrete floors, scribed and self-levelling falls with mechanical bond to slab. Falls confirmed by laser before tanking — never by eye.
Linear drains (Easy Drain Multi or Schluter Kerdi-Line) for contemporary look — 80 mm/sec flow handling. Centre drains where access is restricted. Always a high-flow trap, easy to remove for hair-clearance, with adequate inspection.
Forming a recessed floor in a joisted upper room often requires sistering or trimming joists to maintain structural depth. We do this to Building Regs Doc A and certify it.
Floor: 600x300 mm porcelain min, R10 slip rating or better. Walls: large-format porcelain for fewer grout lines. Mosaics in shower base only where falls demand them. We grout with stain-resistant epoxy in shower zones.
10 mm toughened glass on minimal fixings — wall-mounted, channel-mounted or freestanding. Either single fixed screen, walk-in two-pane, or full enclosure. We use Aquatec, Crosswater, Matki or similar grade.
Foldable seats (Pressalit), grab rails on tanked plywood back-grounds (NOT plasterboard), level-access entry with anti-slip floor, thermostatically controlled shower valves at safe pre-set temperatures.
Wet rooms generate huge moisture. Continuous-run extractor with humidity boost is mandatory — 15 l/s minimum, ducted in rigid pipe to atmosphere, with insulated runs in cold lofts.
Fully tanked. 25-year waterproof system warranty. DFG-grant work undertaken. 30 years of plumbing engineering — your wet room is built to outlast everything around it.
