Can You Move a Toilet? Relocating Bathroom Plumbing Explained
Want to change your bathroom layout? Moving a toilet, basin or shower is possible — here is what is involved and what it costs.
One of the most common renovation questions: "can we move the toilet?" The short answer is usually yes — but the distance and the existing soil pipe determine how easy and costly it is.
The Soil Pipe Is the Key
A toilet needs to connect to the soil stack with enough fall (gradient) for waste to drain by gravity — typically a minimum 1:40 slope. The further you move the toilet from the stack, the more this matters.
Short Moves
Shifting a toilet a short distance is straightforward — we re-route the waste under the floor or in a slim boxed pipe.
Longer Moves and Macerators
If gravity drainage isn't practical, a macerator (e.g. Saniflo) pumps waste through small-bore pipes, giving much more layout freedom. They are reliable but slightly noisier and need power.
Basins and Showers
Waste from basins and showers is easier to move than a toilet because the pipes are smaller and more flexible.
Our Advice
Plan the layout around the soil stack where possible to keep costs down, and use a macerator only when it unlocks a much better layout.

Frequently Asked Questions
How far can a toilet be from the soil pipe?
With gravity drainage, the practical limit depends on achieving the right fall — often a few metres. Beyond that, a macerator is usually the answer.
Are macerator toilets reliable?
Modern units are reliable if used correctly (no wipes or excess paper). They are a great solution for basements, lofts and awkward layouts.
