Can I fit a linear drain to existing pipework?

Often yes, but the existing outlet position and depth usually dictate which drain can be used. If the pipe can be reached from the channel position with adequate fall and depth, a linear drain is feasible — otherwise look at low-profile or side-outlet models, or retain a point drain.

What to check first

Check Why it decides feasibility
Outlet position The channel must reach the pipe without moving it
Pipe diameter Determines whether an adaptor is needed
Pipe depth below finished floor Determines whether the body has enough room
Outlet direction Horizontal or vertical — decides which body type works
Available fall The run to the stack must still fall adequately
Access Whether the run can be connected once the body is in place

Options when the pipe does not suit

  • Low-profile body — fits shallower build-up where a standard body would not
  • Side outlet — keeps the pipe within a thin build-up rather than below it
  • Offset outlet — many bodies allow the outlet to be positioned along the channel
  • Adaptor — connects a new body to an existing pipe diameter
  • Retain a point drain — if the pipework genuinely will not suit a channel

Movement or relocation of the pipe

Where the pipe must move, this usually means breaking out more floor and forming a new route with correct fall. It is a larger job, but in a full renovation the floor is often open anyway. Plan it before tiling, not after.

Practical approach

  1. Open up the floor at the planned drain position
  2. Measure pipe size, direction and depth
  3. Send the measurements (and a photograph) for confirmation
  4. Order the matching body and any adaptor
