Common Pipework Diversion Projects
Typical scenarios we handle:
Kitchen Island Sink Installation
Most popular kitchen diversion:
Challenge:
- Sink traditionally on wall
- Island unit in room center
- Need water supply and waste to island
- No walls to hide pipes
Our Solution:
Water Supply:
- Route 15mm copper or plastic pipes under floor
- Run from existing supply point to island location
- Install isolation valves beneath island unit
- Conceal completely under flooring
- Provide adequate pressure at island
Waste Pipe:
- 40mm waste pipe under floor to soil stack
- Maintain minimum fall (1:40 gradient)
- May require floor level changes
- Consider waste pump if fall insufficient
- Ensure proper venting
Considerations:
- Suspended timber floors (easy access)
- Concrete floors (may require channeling)
- Underfloor heating (careful routing needed)
- Waste pipe gradient critical for drainage
Cost: £300-£600 typically (depends on distance and floor type)
Sink Relocation Within Kitchen
Moving sink to different wall:
Scenario:
- New kitchen layout requires sink elsewhere
- Different wall position
- May be perpendicular wall
Process:
- Cap off old supply and waste connections
- Route new supplies to new position
- Install waste pipe to soil stack
- May run pipes:
- Through walls (internal walls)
- Under floors (concealed)
- Surface-mounted then boxed in
- Test all connections leak-free
Cost: £200-£400 depending on distance
Bathroom Relocation
Moving entire bathroom to different room:
Requirements:
Water Supply:
- Extend hot and cold supplies from existing routes
- 15mm for basin/toilet
- 22mm for bath (better flow)
- Adequate pressure for shower
Waste Connections:
- Connect all waste to existing soil stack
- May need soil stack extension
- Waste pipe falls essential
- Boxing in waste pipes
Heating:
- Extend central heating for radiator/towel rail
- Maintain system balance
- Proper pipe sizing
Complexity: Full bathroom relocations require careful planning for waste falls and soil stack access.
Cost: £800-£1,500 for complete pipework diversion
Downstairs Cloakroom Creation
Adding ground floor WC:
Typical Location: Under stairs or utility space
Plumbing Requirements:
Cold Water Supply:
- Connect to mains supply (adequate pressure)
- 15mm supply pipe
- Isolation valves for maintenance
Waste Connection:
- WC requires 110mm soil pipe
- Connect to existing soil stack or external
- May require drilling external wall
- Basin 40mm waste can join soil pipe
Space Considerations:
- Minimum 800mm x 1,400mm room size
- Soil pipe routing dictates WC position
- Ventilation required (building regs)
Cost: £400-£700 for pipework diversions
Open-Plan Knock-Through

- Run under floor (ideal concealment)
- Route through remaining walls
- Box in if surface mounting necessary
Relocate Radiators:
- Move to different walls
- Resize for new room heating load
- Vertical radiators for limited wall space
Service Continuity:
- Maintain water supply throughout house

- Minimize disruption to other rooms
Cost: £500-£1,200 depending on extent
Concealing Exposed Pipework
Hiding unsightly visible pipes:
Options:
Under Floor Routing:
- Lift floorboards
- Route pipes in joist spaces
- Notch joists properly (building regs)
- Replace floorboards
In-Wall Installation:
- Chase walls for pipes
- Suitable for stud walls
- Limited for solid walls (structural concerns)
- Plaster over and redecorate
Boxing In:
- Timber boxing around pipes
- Access panels for valves
- Painted to match décor
- Cost-effective solution
Cost: £200-£500 depending on method and extent
Our Pipework Diversion Process
Professional pipe rerouting methodology:
Step 1: Consultation & Survey
Understanding your requirements:
- Discuss renovation plans
- Review architectural drawings if available
- Assess existing pipework locations
- Measure distances involved
- Identify obstacles (joists, walls, services)
- Discuss concealment preferences
Free site visit and assessment.
Step 2: Route Planning
Designing optimal pipe routes:
Considerations:
Water Supply Pipes:

Waste Pipes:
- Critical: Maintain proper fall (gradient)
- Minimum 1:40 fall for 40mm waste
- Straighter runs better (fewer blockages)
- Access for maintenance/clearing
- Proper venting to prevent siphonage
- Connect to soil stack correctly
Heating Pipes:
- Maintain system balance
- Proper flow and return routing
- Insulation to prevent heat loss
- Allow for expansion
- Support adequately
Floor/Wall Penetration:

Pipework Diversion Methods
Different routing techniques:
Under Floor Routing
Most common concealment method:
Suspended Timber Floors:
Advantages:
- Easy access (lift floorboards)
- Ample space for pipes
- Simple routing between joists
- No structural concerns
- Removable for future access
Process:
- Lift floorboards along route
- Drill joists for pipe passage
- Notch joists if necessary (regulations apply)
- Install pipes with proper support
- Insulate if running over unheated space
- Replace floorboards securely
Notching Rules (Building Regs):
- Notches max 0.125 x joist depth
- No notches in middle third of span
- Drill holes max 0.25 x joist depth
- Holes minimum 3 x diameter from edge
Concrete Floors:
Challenges:
- Difficult to access
- Requires floor channeling (dusty, disruptive)
- May need floor level raising
- Expensive compared to timber floors
Options:
- Channel concrete (cut, remove, install, fill)
- Raise floor level (build up with screed)
- Surface mount and box in
- Run in ceiling below (if basement/ground floor)
In-Wall Installation
Concealing pipes in walls:
Stud Walls (Plasterboard on Timber):
Advantages:
- Easy to hide pipes
- Cavity space available
- Simple installation
- Access via removable panels possible
Process:
- Remove plasterboard section
- Install pipes in cavity
- Clip to studs securely
- Insulate against noise
- Replace plasterboard
- Plaster and decorate
Solid Walls (Brick/Block/Stone):
Challenges:
- Chasing required (cut channels)
- Structural implications
- Depth limitations
- Plastering over needed
Regulations:
- Horizontal chases max 1/6 wall thickness
- Vertical chases max 1/3 wall thickness
- No chasing both sides of wall
- Protective capping over pipes
Better Solutions for Solid Walls:
- Surface mount and box in
- Route under floor instead
- Use available cavities
Boxing In
Concealing surface-mounted pipes:
When Used:
- Concrete floors prevent under-floor
- Solid walls limit in-wall routing
- Retrofit situations
- Temporary/rental properties
Construction:
- Timber framework
- Plasterboard or MDF facing
- Access panels for valves
- Painted to match décor
Advantages:
- Cost-effective
- Reversible
- Provides access
- Quick installation
Considerations:
- Reduces room space slightly
- Visible (though neat)
- May limit furniture placement
External Wall Routing
Running pipes outside:
When Necessary:
- Internal routing impossible
- External extensions
- Garden buildings

- Proper insulation (prevent freezing)
- UV-resistant where exposed
- Secure fixing to walls
- Neat appearance
Frost Protection:
- Insulate all external pipes
- Trace heating for exposed sections
- Drain facility for winter
- Protect from frost damage

- No weakening structure
- Alternative routing if necessary
Sound Insulation
Noise Reduction:
