Garden Rooms with Toilet or Shower Room
It is becoming increasingly popular to include a toilet or full shower room in a garden room building. While this can be an expensive addition, it significantly enhances the building's usability, both now and in the future.
When it comes to adding these facilities, you have two options: an off-grid system or a system connected to the mains supply. Off-grid systems are generally more cost-effective and quicker to install, while mains-connected systems require more extensive groundworks, increasing the overall cost. If you choose to work with your supplier on a turnkey basis, they will typically manage the groundworks and connections as part of their service, ensuring a seamless installation process.
We’ve curated this collection of garden room projects featuring cloakrooms or shower rooms to highlight how these facilities can be seamlessly incorporated into a garden room. The articles are listed with the most recently featured examples first, so use the pagination to explore all the designs.
