Garden Rooms with Toilet or Shower Room
Including a toilet or full shower room within a garden room is becoming increasingly popular. While it does add to the overall cost, it can significantly extend how the space is used — both now and in the future — helping the building feel far more like a room within the home rather than a simple garden outbuilding.
It’s important to be aware that not all garden room companies offer the option of adding a cloakroom or shower room. Among those that do, the approach can vary considerably. Some suppliers will form the internal layout — creating partition walls and allowing space for future use — but leave the plumbing and sewerage connections to be arranged separately. Others offer a fully managed, turnkey service, taking responsibility for the layout, plumbing, connections, and the associated Building Control sign-off where required.
In practical terms, full shower rooms are almost always connected to the mains supply, which involves additional groundworks and increases the overall cost. Simple cloakrooms can sometimes be designed using off-grid systems, but this is typically a secondary option offered by a smaller number of specialists and is generally limited to basic WC installations rather than full bathrooms.
If you're still exploring your options, our independent guide covers garden rooms of every type — with costs, planning guidance, and a full company directory.
