Exposed soil pipes, supply pipes, and overflow pipes around a toilet are one of the most common bathroom eyesores. Fortunately, there are several practical ways to hide them — ranging from a simple boxed-in casing you can build in a day to a full wall-hung toilet installation that eliminates all visible pipework permanently. Which approach is right for you depends on your budget, bathroom layout, and how much disruption you are willing to take on.
Option 1: Boxing In With a Stud Frame
The most popular and affordable solution is to build a stud frame around the pipes and clad it in moisture-resistant board or pre-finished panels.
How It Works
A lightweight timber or metal stud frame is fixed to the floor and wall around the pipe run. The frame is then clad in 12.5 mm moisture-resistant (MR) plasterboard for tiling, or in pre-finished bathroom panels (PVC cladding or waterproof MDF) for a paint-ready finish.
What You’ll Need
- 47 mm x 47 mm C16 timber studs or 50 mm metal C-stud track
- 12.5 mm MR plasterboard (green board) or pre-finished PVC wall panel
- Screws, drywall screws, screw anchors for fixing to tile/brick
- Flexible sealant (sanitary silicone)
- Access panel (if the pipes need periodic inspection — e.g., if there is a solvent-weld joint behind the boxing)
Step-by-Step
- Mark out the boxing — identify the widest pipe run and allow 20–30 mm clearance around it. The boxing should be as shallow as possible to minimise the space it takes.
- Fix a sole plate to the floor and a head plate above (if running up to a shelf or ceiling). Use a spirit level to ensure they are plumb.
- Build side returns where the boxing meets the wall, fixing studs with appropriate wall fixings for your wall type (plastic plugs and screws for solid masonry, timber fixings into stud locations for studwork walls).
- Fix the cladding — for plasterboard, use drywall screws at 150 mm centres; for PVC panels, use the manufacturer’s adhesive or the panel’s own clip system.
- Seal all edges with sanitary silicone between the boxing and floor/wall.
- Install an access panel (a flush-fitting hatch, available for £15–£40 from plumbers’ merchants) if there are any joints, valves, or connections behind the boxing that may need future access.
Cost
| Item | DIY cost |
|---|---|
| Stud timber (2.4 m lengths x 4) | £12–£20 |
| MR plasterboard (one sheet) | £12–£18 |
| Pre-finished PVC panels (alternative to board) | £20–£60 |
| Fixings, screws, silicone | £10–£15 |
| Access panel | £15–£40 |
| Total DIY materials | £50–£150 |
| Tradesperson (carpenter or plumber) | £150–£300 |
Option 2: Pre-Made Pipe Boxing (PVC Extrusion)
For a single pipe run against a wall rather than a full corner boxing, snap-on PVC pipe boxing is the quickest solution. These are pre-formed plastic channels in standard sizes (typically 100 mm x 50 mm, 130 mm x 80 mm) that clip over the pipe and fix to the wall.
- Cost: £5–£15 per metre
- Suitable for: Single supply pipes, 15 mm or 22 mm diameter
- Not suitable for: 110 mm soil pipes (too large for standard clip boxing)
- Finish: Available in white or chrome-effect; can be painted
PVC pipe boxing is not waterproof at the joints so is best used in dry areas, or sealed with silicone if near the toilet.
Option 3: Wall-Hung Toilet With Concealed Cistern
The cleanest solution — and the one increasingly standard in new UK bathrooms — is a wall-hung toilet with the cistern concealed in a purpose-built frame (called an in-wall carrier frame or concealed cistern unit) built into a false wall.
The carrier frame holds the cistern, flush mechanism, and waste pipe connection, all hidden behind a plasterboard face wall. The toilet bowl hangs from the frame at a comfortable height.
Benefits
- No exposed pipes at all — supply, waste, and overflow are all hidden
- Easier to clean underneath (floor-mounted toilet contact area eliminated)
- Height-adjustable during installation (useful for accessibility)
- Modern look compatible with all tile and panel finishes
Drawbacks
- Significant upfront cost (see below)
- Reduces bathroom depth by 120–200 mm (the frame and plasterboard add that to the wall)
- Future access to the cistern is via the flush actuator panel — more complex if the cistern develops a fault
Cost
| Component | Cost |
|---|---|
| Concealed cistern carrier frame (e.g., Geberit Duofix) | £150–£350 |
| Wall-hung toilet pan | £100–£400 |
| Actuator plate (flush button) | £20–£80 |
| Plasterboard, studwork, tiling | £80–£200 in materials |
| Installation (plumber + tiler) | £300–£600 |
| Total installed | £650–£1,600 |
Option 4: Furniture and Decorative Screening
For renters or those not wanting permanent works, a toilet storage unit, freestanding cabinet, or decorative wicker basket screen can visually reduce the prominence of exposed pipes without any construction. This is not watertight or permanent but costs as little as £30–£80 for a suitable bathroom storage unit.
Building Regulations Considerations
Boxing in pipes is not a notifiable building works activity in England and does not require Building Control sign-off. However:
- Access panels are required wherever there are joints in supply pipes, soil pipes, or isolation valves behind the boxing (per BS 8000-13 plumbing good practice and to comply with Part H of the Building Regulations for drainage access)
- Soil pipes (110 mm) must not be sealed permanently — a rodding point or access cover must be provided
- Fire-stopping — if the boxing passes through a fire-separating floor (e.g., in a flat), the void must be fire-stopped with intumescent products
Which Option Is Right for You?
| Situation | Best option |
|---|---|
| Renting / temporary | Pre-made PVC boxing or decorative screen |
| Simple pipe run, tight budget | Stud-frame boxing with PVC panels |
| Full bathroom renovation | Concealed cistern wall-hung system |
| Single supply pipe only | PVC clip-on boxing |
| Accessibility or future-proofing | Wall-hung toilet (height adjustable) |
For most homeowners doing a partial bathroom refresh, stud-frame boxing in moisture-resistant board is the best balance of cost, durability, and flexibility. It is a realistic DIY project for a confident builder; if you are tiling the face, a tiler will often incorporate the boxing into their scope.
