Request a call-backOne Stop Bathrooms & Interiors supplies and fits waterproof wall panels across Workington, Whitehaven, Cockermouth, Maryport, Egremont and Keswick. Both ranges we stock — Multipanel and Naturepanel — come from Grant Westfield, and both are on the showroom wall at Unit 8, Clay Flatts Trading Estate.
The maker
Grant Westfield is the UK's leading maker of waterproof wall panels, manufacturing in Britain — and it's the company behind both ranges we stock. The shared engineering is the point: 100% waterproof panels, no grout anywhere, and 30-year warranties on both.

Multipanel
Marble, stone, wood and plain finishes with Hydrolock joints for a near-seamless wall. Fits over existing tiles in most cases — ideal for showers, wet rooms and full bathrooms.

Naturepanel
Best Surface of the Year 2024 at the KBB Focus Awards: a real-wood slat look with a 6.4mm etched shadow line, fully waterproof so it runs straight through the shower. Décors include Bleached Cuneo Oak, Brown Cuneo Oak, Warmia Walnut and Shiplap — for bathrooms, kitchens, hallways and living rooms.

How panels are fitted
Amanda checks the walls at the free home visit — condition, layout and whether panels can go straight over what’s there.
Panels are cut and fitted by our own team, often directly over existing tiles — no rip-out mess.
Hydrolock joints seal as they lock, so the wall is finished in a fraction of the time tiling takes — no drying, no grouting.
Strip-out (where needed), fitting and finishing on one quote — and if anything isn’t right after handover, call us and we come back.
The honest caveat: tiles are still the better choice when you want pattern, small formats or mixed layouts — that's why we stock Porcelanosa and Nu Tile too, and plenty of rooms we fit use both.
FAQ
Yes — both Grant Westfield ranges One Stop stocks are 100% waterproof and safe in showers and wet rooms. Panels seal with the Hydrolock watertight joint, so the whole wall is one continuous waterproof surface with no grout to fail.
In most cases, yes. Multipanel fits directly over sound existing tiles, plaster, plasterboard, stud walls and even concrete — usually no rip-out, far less mess, and a much faster fit. We check the wall's condition at the home visit before confirming.
Faster, clearly: there are no drying or grouting stages and usually far less wall preparation, so fitting takes days rather than weeks. On cost, materials are broadly comparable — the saving is labour time. Amanda prices panels and tiles like-for-like after a home visit if you want the honest comparison for your room.
Both Multipanel and Naturepanel carry a 30-year manufacturer's warranty when installed and maintained in line with the guidelines. With no grout to crack, discolour or harbour mould, a panelled wall needs almost no maintenance over its life.
Yes — full-size panels and sample boards for both ranges are on the showroom wall at Unit 8, Clay Flatts Trading Estate, Workington, with samples to take home. Open Monday–Friday 9am–4:30pm and Saturday 10am–2pm, free parking, no appointment needed.
