Small pools are having a real moment
Not every garden has room for a full-length pool. And not everyone wants one. Lots of people simply want somewhere to cool off on a hot afternoon, unwind after work or take a refreshing dip first thing in the morning.
That’s where a plunge pool comes in. It’s a compact pool designed for soaking, relaxing and short swims rather than long lengths. It takes up far less space than a traditional pool, and it can be surprisingly versatile.
In this guide we’ll explain what these small pools are, the sizes you can expect, the benefits of keeping the water warm or cool, and some ideas for fitting one into your garden. We’ll keep it simple, and we’ll be honest about what they can and can’t do.
Where the name comes from
The idea of a small, deep-ish pool for dipping into goes back a long way. Think of the cold baths in Roman bathhouses or the pools beside a sauna in Scandinavia. Today’s versions are more comfortable, but the principle is the same. It’s a place to immerse yourself, not to train for a triathlon.
A plunge pool is all about quality time in the water
So what sets these pools apart from any other small pool? Mostly it comes down to purpose.
Designed for dipping and soaking
A standard pool is usually built for swimming. A plunge-style pool is built for being in the water. You might float, sit on a step with a drink, stretch after a run or simply cool down. For many people that’s exactly how they’d use a bigger pool anyway.
Compact but still properly deep
Although they’re small in footprint, these pools are usually deep enough to stand in comfortably with the water around your shoulders. That depth is what gives them their refreshing, full-body feel. It’s very different from paddling in a shallow splash pool.
Simple to live with
Less water means less to heat, less to filter and less to treat. The routine jobs are the same as with any pool, but on a smaller scale. For busy households, that can make pool ownership feel much more manageable.
Typical sizes vary more than you might expect
There’s no official definition of what counts as a plunge pool. In general, though, they’re a lot smaller than a family swimming pool.
Common shapes and dimensions
Most compact pools of this kind are somewhere in the region of two to four metres long, and a little narrower than they are long. Depth is often somewhere around 1.2 to 1.5 metres, though designs vary. Some are square, some rectangular and some are round.
These are broad guides only. The right size for you depends on your garden, how many people will use the pool at once and what you want from it. A pool for one or two people can be quite small. One the whole family will pile into on a summer’s day needs a bit more room, plus space around the edge for towels and chairs.
Thinking about how you’ll use it
Before settling on a size, it’s worth picturing a normal week. Ask yourself:
- Who will use it? A couple wants something different from a family with teenagers.
- What will you do in it? Relaxing, cooling off and gentle exercise all suit a compact pool. Swimming proper lengths does not, unless you add a current.
- Where will you sit? Built-in steps and benches make a small pool far more comfortable.
- How often will you use it? Daily dips make a strong case for heating and a good cover.
Our compact one-piece pools
We install one-piece pools, and several of our more compact shapes can work beautifully as a small pool for dipping and relaxing. Each is lowered into place as a single moulded shell, which keeps installation quick and tidy. You can explore our full range of pools to see the shapes available, and we’ll help you choose the one that suits your space.
Heated or cool, a plunge pool can suit your routine
One of the nicest things about a small pool is how flexible it is. You can keep it warm and inviting, keep it cool and bracing, or change things with the seasons.
Keeping it warm for relaxing
A heated pool is lovely for unwinding. Because there’s less water, it can come up to temperature more readily than a larger pool, and a well-fitted cover helps hold that warmth. On a cool spring evening, slipping into warm water under the sky is hard to beat. Our guide to swimming pool heating explains the main systems.
Keeping it cool for a refreshing dip
Cold water immersion has become very popular. Lots of people enjoy a short, chilly dip for the way it makes them feel afterwards. If that’s you, a cool pool can become part of your daily routine. We’ve written more about this in our guide to cold water therapy.
If you’re new to cold water, please take it gently. Start with short dips, never go in alone, and speak to your GP first if you have any health concerns.
Changing with the seasons
Some owners keep the water warm through spring and autumn, then let it run cooler in summer when the sun does the work. With the right equipment you’re not locked into one choice.
The benefits go beyond saving space
People often choose a compact pool because their garden is small. Many end up loving it for other reasons too.
Easier on the garden
A plunge pool leaves more room for lawn, planting, a dining area or a play space. It can sit comfortably alongside everything else, instead of taking over.
Quicker to install
With a one-piece shell, there’s less digging and less time on site than with a big pool. That means less disruption for you and your neighbours.
Simpler to maintain
Many owners are pleasantly surprised by how little time the weekly routine takes. With a smaller volume of water, you’ll typically use fewer chemicals and the filter has less work to do. You’ll still need to test and balance the water regularly, and keep the filter clean.
If you’re handling chemicals yourself, always follow the label, wear gloves and eye protection, never mix chemicals, add chemical to water and never water to chemical, keep swimmers out until the water is balanced, and store everything away from children and pets.
Good for wellbeing
A short soak can be a lovely way to switch off. Warm or cool, time in the water often becomes a small daily ritual that people really look forward to.
Clever garden ideas help a small pool shine
Because a compact pool is small, the design around it matters a great deal. Here are some ideas we love.
Frame it with planting
Hedging, grasses and climbers can make a small pool feel private and sheltered. Evergreen planting gives structure all year round. Just keep trees that drop lots of leaves a little further away, so you’re not skimming every day.
Scented plants near the steps are a lovely touch. Lavender, rosemary and jasmine all cope well with sun and add a gentle fragrance as you sit by the water. Keep thorny shrubs well back from bare feet, and choose plants that won’t shed petals straight into the pool.
Make the steps a feature
Wide internal steps double up as seats. They’re a comfortable place to sit with your shoulders in the water, and they make getting in and out easy for everyone.
Add a place to rest
A small terrace with a couple of loungers or a bench turns the pool into a proper destination. Natural stone, porcelain paving and timber decking all work well.
Light it for evenings
Underwater lighting and a few garden lights transform a compact pool after dark. It becomes a glowing focal point you can enjoy even when you’re not swimming.
Think about sun and shelter
Try to place the pool where it catches the afternoon or evening sun and is protected from the prevailing wind. Our guide to the best options for a small garden pool has more ideas for compact spaces.
Practical points to consider before you commit
Every garden is different, so a few practical questions are worth answering early.
Who a compact pool suits best
Over the years we’ve noticed that small pools tend to delight a few kinds of people in particular:
- Couples and downsizers who want the pleasure of a pool without a large garden to look after.
- Keen runners and gym goers who like a cool dip to finish a workout.
- Families with young children who mostly want to splash, play and cool off.
- Town and village gardens where space is precious and every metre counts.
If you recognise yourself in that list, a plunge pool is well worth a closer look. If you dream of swimming proper lengths every morning, a longer pool or a swim spa may suit you better, and we’re happy to talk that through honestly.
Access and ground conditions
We’ll need to get a digger into the garden and lift the shell into place. We’ll check access, ground conditions and any services underground during our site visit.
Planning and building control
Many garden pools fall within permitted development, but it depends on your property, the pool’s size and its position. Check with your local council before you go ahead, particularly if you live in a conservation area or a listed building.
Where it goes in the garden
Position makes a big difference to how often you’ll use the pool. Close to the house means it’s easy to pop out for a quick dip in your dressing gown. A spot near the kitchen or living room also means you can keep an eye on children from inside. Further down the garden can feel more like a private retreat, but it’s worth thinking about the walk back on a chilly morning.
The plant room equipment needs a home too. It’s usually tucked away in a small housing nearby, so we’ll plan that in from the start.
Safety
A small pool is still deep water. Supervise children at all times, and consider a safety cover or fencing. A lockable cover can give extra peace of mind. For more ideas, take a look at our article on above ground pools.
Budget
We don’t put prices in our guides, because every project is different. What we can do is give you a tailored quote once we’ve seen your garden and talked through what you’d like. If you’re weighing up your options, our guide to container swimming pools is worth a look.
Plunge pool questions we get asked a lot
Can I swim in a small pool like this?
You can move about and do gentle exercise, but it’s not really built for lengths. A swim current can help if you’d like more of a workout.
Does it need a filter and pump?
Yes. Any pool needs good filtration and circulation to keep the water clean and safe, whatever its size. The equipment is simply scaled to suit the volume of water.
Can I use it all year?
With heating and a good cover, many owners use their pool for much of the year. If you prefer cold dips, you might use it even more in winter.
Is it cheaper to run than a big pool?
There’s less water to heat and treat, so it’s usually more manageable. We’ll give you a realistic estimate for your setup.
How quickly can it be installed?
A one-piece shell is much quicker to install than a pool built on site. We’ll give you a realistic timeline after our survey.
A plunge pool could be the perfect fit for your garden
If you want the joy of water at home without giving your whole garden to a pool, a compact pool is well worth considering. Warm or cool, it can become one of your favourite places to be.
