How we supply it: WPC and PVC doors are arranged through a partner door dealer who quotes, supplies and bills them and pays us a referral commission. Ask for frame and shutter together; we schedule them after your bathroom tiling, with the hardware on the same order.
In one line: A WPC door is made of wood-plastic composite, a dense mix of wood fibre and thermoplastic, while a PVC door is a shutter of extruded PVC panels, often hollow; both are made for wet areas where timber swells.
WPC, PVC or flush for a bathroom?
| Point | WPC (solid) | PVC (hollow) | Flush (timber core) |
|---|---|---|---|
| Water at the bottom edge | Unaffected | Unaffected | Swells unless sealed |
| Termites | Not attacked | Not attacked | Can be attacked |
| Rigidity | High | Low to medium | High |
| Holding hinges and locks | Good | Needs reinforced zones | Good |
| Weight | Heavy | Light | Medium |
What WPC and PVC doors are
A WPC door is made of wood-plastic composite, a dense mix of wood fibre and thermoplastic, while a PVC door is a shutter of extruded PVC panels, often hollow; both are made for wet areas where timber swells.
Because neither material rots, the weak point moves to the frame. A WPC shutter in a timber frame still fails at the frame's wet bottom ends.
Door types for wet areas
| Type | Build | Best for |
|---|---|---|
| Solid WPC shutter | Dense extruded or pressed board | Daily-use bathrooms |
| PVC shutter | Hollow or foam-filled panels | Low-use bathrooms, stores |
| FRP shutter | Fibreglass skins over a core | Wet areas wanting a moulded look |
| WPC or PVC frame | Extruded frame with rebate | Any wet-area opening |
| uPVC glazed door | Window-style profiles and glass | Balconies, utility areas |
Sizes and fitting details
- Bathroom openings are commonly about 2.5 × 7 ft (750 × 2100 mm); measure after tiling
- Shutter thickness is commonly about 25–30 mm
- Fix the frame after wall tiling, with screws into plugs or holdfasts, never resting in the wet floor bed
- Leave a small gap under the shutter for ventilation and floor water
Checks before fitting
- Confirm the quote says solid WPC or hollow PVC; tap and weigh the shutter to check.
- Measure thickness and lay it flat to check for twist.
- Inspect edges and corners for cracks, especially on PVC.
- Ask for reinforced zones at the hinge and lock positions on PVC shutters.
- Check the surface finish is even and not peeling at the edges.
Storing and drilling
- Store flat or fully supported upright, out of direct sun; PVC softens and bends in heat.
- Keep the protective film on until fitting is finished.
- Pre-drill pilot holes with sharp bits; WPC is dense and splits around forced screws.
Bathroom door mistakes
- A WPC shutter hung in a timber frame whose bottom then rots.
- Hinges screwed into hollow PVC without reinforcement.
- No gap at the bottom, so the shutter scrapes and floor water wicks up.
- A laminated flush door sold as 'waterproof'.
- Heavy locks on a light PVC shutter.
