Adding Bathrooms to Garden Rooms.

Are you considering expanding your living space into your garden?

Building a garden room offers endless possibilities, from creating a tranquil home office to a vibrant entertainment space.

But have you thought about adding a bathroom to your garden room?

In this post, we'll explore the benefits and considerations of incorporating a toilet and shower into your garden building.

Can you put a toilet and shower in a garden room?

Yes! With proper planning and the right infrastructure, water, electricity and drainage; you can transform your garden room into a fully functional living space complete with a bathroom. Whether you're picturing a refreshing shower after a workout in your home gym or providing convenient facilities for guests, integrating a toilet and shower adds both comfort and practicality to your garden retreat.

What to consider when installing a toilet and shower in a garden room:

Water Supply: Decide between off-grid solutions or connecting to your mains water supply. While off-grid options (for example water tanks/electric well pumps) offer independence, connecting to mains water ensures reliability. Consult with experts to determine the best plumbing solution for your garden room.

Ventilation: Prevent moisture buildup and maintain air quality with proper ventilation. An extractor fan is essential to mitigate dampness and ensure a comfortable environment, windows alone are not sufficient.

Drainage: Prior to incorporating a shower or toilet into your garden room, it's crucial to consider the disposal of water waste. Typically, this involves digging a trench for water pipes to connect to the nearest sewer, facilitating the efficient removal of wastewater. Ensuring that these pipes are installed below the frost line in the ground is essential to prevent potential damage during colder months. While this step may initially seem onerous and costly, the long-term benefits in terms of functionality and durability make it a worthwhile investment.

Electricity Supply: This is fairly obvious and we’ve never built a garden room that hasn’t been wired for electricity to power lights, plug sockets etc. All our garden rooms are fully-wired with lights, sockets and switches with all wires terminated in an outdoor fuse box as standard. Consider anything extra at design stage; sockets for shavers, hairdryers, ventilation fans or underfloor heating. Explore eco-friendly alternatives such as solar panels for sustainable energy solutions. We can install PV/solar panels.

Insulation: Prioritise comfort by investing in quality insulation. All Cosy Garden Rooms are built using premium-quality wall, floor and roof insulation and all our windows are double-glazed. Heating options like towel rails and underfloor heating can be fitted to create a cosy ambiance, even on chilly days.

Privacy: Maintain privacy within your garden room by strategically positioning windows, choosing opaque or frosted glass for bathroom doors and/or windows. A very neat solution is windows with integrated blinds; we can supply and fit these to any building.

Maintenance: Plan for easy maintenance of your garden room and bathroom facilities. Choose durable materials that require minimal upkeep. Regularly inspect plumbing, electrical, and ventilation systems to prevent issues and prolong the lifespan of your garden room. For your peace of mind all Cosy Garden Rooms come with 10-year manufacturers guarantee.

Functionality: Think about how you'll use your garden room and tailor the layout and amenities to suit your specific needs. Whether it's a compact en-suite for occasional use or a spacious bathroom for daily use, prioritise functionality and efficiency in your design. With no off the shelf products, Cosy Garden Rooms can build you exactly what you require, any shape, size or specification.

Planning Permission & Building Regulations: While most garden rooms fall under permitted development rights, certain factors like size, location, and land use may require approval. In addition to planning permission, familiarise yourself with building regulations governing the construction of garden rooms with bathrooms. Compliance with structural, fire safety, and health and safety standards ensure the safety and legality of your project.

By addressing these additional considerations, you can create a garden room with a bathroom that not only enhances your outdoor living space, increases the value of your property and also meets your practical needs and aesthetic preferences. Cosy Garden Rooms offer a turnkey approach to all garden room projects; we are happy to help and offer advice.
