A garden spa does not need a grand budget or a permanent building. With a clear plan and a few well chosen elements, you can create a calm, practical space that you will use in every season. Think about purpose, layout, and habit. When those three align, the details fall into place.
Decide what your spa is for
Start by choosing your primary outcome. If you want a place to decompress on weeknights, keep the setup close to the back door and simple to operate. If your goal is weekend connection, plan for seating and an area to rest between heat rounds. If you want recovery after training, design for both heat and short cooling periods so you can alternate without fuss.
A wood fired sauna is the ideal anchor. Portable models deliver authentic temperatures and soft steam, yet they set up quickly and do not require foundations. If you are exploring options, look at the range from PortaSauna, a specialist in portable wood fired saunas that suit British gardens and coastlines: PortaSauna. If you like the idea of hot and cold together, their plunge collection pairs neatly with any sauna for contrast sessions: Portable Sauna.
Choose the right spot
Most gardens have a natural place for a small spa. Look for level ground, a bit of wind protection, and a view you enjoy. A hedge line or fence corner works well. Leave safe clearances around the stove and flue, and plan access so you can step out into cool air between heat rounds. If the area puddles after rain, add a shallow gravel trench so water runs away from patios and beds.
Size wise, think in shed footprints. A compact sauna tent and a small rest area will fit comfortably in a space of three by three metres. If you add a plunge tub, allow a stepping zone around it so you can move without shuffling.
Plan a simple flow
Spa time should feel effortless. Create a loop so you are not crossing yourself with damp towels and hot doors.
- Warm zone: the sauna sits in the most sheltered spot, with enough room to open the door wide.
- Cool zone: a plunge or hose within a few steps so you can cool briefly and safely.
- Rest zone: two or three chairs, a small table for water and tea, and a robe hook at shoulder height.
Keep the route clear of trip hazards. If you use rugs, choose quick-dry outdoor types and pin the corners.
Get the atmosphere right
You do not need designer fixtures. Use warm white string lights at head height, then add one or two path lights near the ground for safety. Plant fragrant, hardy herbs in pots, such as rosemary and piney evergreens, to complement the wood stove scent. Sound is optional. Many people prefer the quiet crackle of the fire to music.
Build a routine that sticks
Habit is where the benefit lives. Try this pattern as a starting point.
- Two short sessions midweek: two or three rounds of ten to fifteen minutes, with a short cool in between.
- One longer session at the weekend: slower pacing and longer rests outside, ideally shared with a friend.
Keep phones indoors so your brain registers a real change of scene. Drink water, and add a pinch of salt after longer sessions.
Heat and cold, done simply
Contrast therapy can make you feel both relaxed and clear headed. Begin mild. Ten minutes of heat, thirty to sixty seconds of cool air or water, a few minutes of rest, then repeat if you like. You should feel refreshed rather than shocked. If you have a medical condition, are pregnant, or take medication that affects blood pressure, seek advice first.
Practical care and safety
Use seasoned hardwood with a moisture content near 15 to 20 percent. Dry fuel gives a cleaner burn and steadier heat. Crack a vent to keep air fresh, follow the maker’s guidance on flue checks, and let embers cool fully before disposing of ash in a metal bucket. Speak to neighbours before your first weekend session. A friendly chat and reassurance about dry wood used at sensible times prevents concerns later.
Costs, time, and year round use
Portable wood fired saunas are much more approachable than fixed buildings. Running costs are mostly firewood and a little water for rinses or a cold tub. Because tents heat quickly, you can enjoy a proper session on a Tuesday night, not just on special occasions. Shorten heat rounds during hot weather, lengthen outdoor rests, and keep the ritual going through summer.
Your garden spa does not need to look like a brochure. It needs to be easy, welcoming, and close at hand. Choose a heat you love, place it well, and protect a few hours each week. The rest is memory, conversation, and better sleep.
