Two kinds of water can work beautifully in one garden
Many of the families we speak to start with one idea. Some want a pool for swimming and summer fun. Others want a hot tub for cold evenings and sore muscles. Quite often, halfway through the conversation, they realise they’d love both.
That makes sense. A pool and hot tub do very different jobs. The pool is for swimming, playing and cooling off. The hot tub is for warmth, massage and quiet time. Together they give you a garden you can enjoy in almost any season.
In this guide we’ll look at how the two fit together. We’ll cover layout, heating, water care, safety and the design choices that help everything feel like one plan rather than two separate purchases.
Who this guide is for
It’s written for homeowners who are planning a new garden pool, or who already have a pool and are wondering whether a spa would be a good addition. It also works the other way round, if you own a spa and are thinking about adding a pool later.
Each one gives you something the other can’t
Before you plan the layout, it helps to be clear about what each part of the garden is for. That way you can size and position them properly.
What the pool brings
- Space to swim, whether that’s gentle lengths or proper training.
- Room for children and friends to play and splash.
- Cooling relief on hot summer days.
- A striking focal point that changes how the whole garden looks.
What the hot tub brings
- Warm water ready to use all year, even in January.
- Massage jets that many people find relaxing after work or exercise.
- A small, sociable space for two to six people to sit and chat.
- Quick use. You can lift the cover and be in within a minute.
Why the pair works so well
The pool tends to be busiest from late spring to early autumn. The hot tub often comes into its own on cooler evenings and through the winter. Having both means the garden keeps earning its place all year. Plenty of owners also enjoy moving between the two, a swim followed by a warm soak.
There’s a social side too. When friends come round, having both gives people different places to gather. The children might stay in the pool for hours, while the adults chat in the warm water nearby. Everyone is outside, together, but doing their own thing.
Planning a pool and hot tub as one design
The biggest mistake we see is treating the spa as an afterthought. When it’s placed wherever there’s a spare corner, it can look cluttered and feel awkward to use.
A better approach is to plan both from the start. Even if you install them at different times, knowing where each will sit helps the whole garden come together.
Think about the route from the house
People use a hot tub more when it’s close to the back door. On a cold night, a short walk makes a real difference. The pool can sit a little further out if the garden allows, where it gets more sun and makes a bigger visual statement.
Keep sightlines in mind
Stand at your kitchen window or patio doors and picture the finished garden. You’ll probably want to see the pool clearly, both for enjoyment and for keeping an eye on children. The spa can often be tucked slightly to one side, framed by planting or a low wall.
Choose one material palette
Using the same paving, coping and edging around both helps them look like they belong together. Timber decking, porcelain slabs and natural stone all work well. Matching lighting colours and finishes adds to the effect. Our guide to pool landscaping has more ideas on tying everything together.
Layout options that work in real gardens
There’s no single right answer. The best layout depends on the size and shape of your plot, the direction of the sun and how you plan to use the space. Here are some arrangements that tend to work well.
- Side by side on a shared terrace. The spa sits at one end of the pool, on the same level, with a generous patio around both. Simple, sociable and easy to supervise.
- Raised spa overlooking the pool. The hot tub sits on a slightly higher terrace, giving bathers a view across the water and garden. Good on sloping plots.
- Separate zones. The pool takes centre stage in the garden, while the spa sits in a sheltered corner closer to the house, perhaps under a pergola or canopy.
- Spa near a garden room. If you have an outbuilding or garden room, placing the spa beside it gives you somewhere to change and warm up.
Leave room for the practical bits
A pool and hot tub each need space for equipment, access for servicing and somewhere safe to store covers when they’re off. Plan paths so you’re not stepping over pipework or squeezing past a plant room door. It’s easy to forget these details on paper and hard to fix them later.
Allow for privacy and shelter
Hot tubs are often used in the evening, when you’ll want a bit of privacy from neighbours. Fencing, hedging, screens or a pergola can all help. Shelter from the wind also makes a big difference to comfort on cold nights.
Heating, covers and running a pool and hot tub together
Owning two bodies of water means thinking about heating and upkeep in a sensible, joined-up way. The good news is that modern equipment makes this much more manageable than many people expect.
Heating
A pool is usually heated to a comfortable swimming temperature during the season. A spa is kept much warmer and is often left at temperature all year. Each normally has its own heating arrangement, sized for its volume and use. If you’d like to understand the options, our guide to swimming pool heating explains the main systems in plain English.
Covers
Covers are one of the simplest ways to keep heat in, keep debris out and help with safety. Most spas come with a fitted insulated lid. For the pool, there are several cover types to consider, from simple floating covers to automatic systems.
Running costs
We can’t give meaningful figures here, because every garden and every household is different. Size, location, shelter, heating method, cover use and how often you swim all play a part. What we can do is give you a realistic estimate for your own plans, so there are no surprises.
Water care
Each one has its own water to look after, and the balance can behave differently because of the temperature. Warm spa water can need a little more attention, especially after a busy weekend. The routine for both is straightforward once you’re used to it:
- Check the water regularly with a reliable test kit.
- Keep filters clean and follow the recommended cleaning schedule.
- Keep the covers on when the water isn’t in use.
- Top up water levels after heavy use or hot spells.
When chemicals are involved, always follow the label. Wear gloves and eye protection, never mix chemicals together, and always add chemical to water, never water to chemical. Keep people out of the water until it’s properly balanced, and store products safely away from children and pets.
Safety matters even more with two kinds of water
With a pool and a spa in one garden, it’s worth giving safety some extra thought. Both need clear rules and sensible physical measures, especially if children or grandchildren visit. Our guide to swimming pool safety covers this in more detail, but here are the main points.
- Supervision. Children should always be watched by an adult when they’re near either kind of water.
- Covers. Keep the spa lid locked when not in use, and use a suitable pool cover.
- Barriers. Fencing or gates around the pool area can help, particularly for younger families.
- Temperature. Hot water isn’t suitable for everyone. Young children, pregnant women and anyone with a health condition should check with their GP before using a hot tub.
- Clear paths. Non-slip surfaces and good lighting help prevent trips when people are moving between the two.
It’s also worth checking with your local council about planning and any other rules that might apply to your particular plans. Most garden projects are straightforward, but it’s always better to ask early.
Choosing the right pool and hot tub for your garden
With so many shapes and sizes available, the choice can feel a bit overwhelming. We find it helps to start with how you’ll really use the garden.
Start with the people
How many of you will use the pool at once? Is swimming for fitness important, or is it mainly for family fun? How many people would you like to fit in the spa? A couple enjoying quiet evenings needs something quite different to a family of five.
Match the scale to the space
A large pool with a tiny spa can look unbalanced, and the opposite is also true. Think about proportions from the patio and from upstairs windows. Leaving enough paving around each helps them feel generous rather than squeezed in.
Consider a swim spa as an alternative
If your garden is on the smaller side, a swim spa could give you some of the benefits of both in one unit. It combines a current for swimming with warm water for relaxing. Some families still choose a separate spa alongside it, but for others it’s the perfect middle ground.
Plan for the future
You might only be able to install one this year. That’s fine. If you know where the second will go, you can run services, plan paving levels and leave space accordingly. It saves disruption later.

Pool and hot tub questions we get asked a lot
Can a pool and a spa share the same equipment?
Usually each has its own filtration and heating, because the water volumes and temperatures are so different. We’ll recommend the best arrangement for your plans.
Should the spa be installed at the same time as the pool?
It doesn’t have to be, but planning both together makes things easier. Even if you install later, it helps to decide the position early.
How far apart should they be?
There’s no fixed rule. Close enough to walk between comfortably, and far enough that each has room to breathe. We can help you find the right balance for your garden.
Will a hot tub be used in winter?
Yes, and for many owners winter is when they love it most. Sitting in warm water on a frosty evening is a real treat.
Do they need a lot of looking after?
Less than people expect. A simple weekly routine, plus regular servicing, keeps both in good condition. We also offer aftercare, servicing and repairs.
Do I need planning permission?
Many garden installations don’t, but it depends on your property and plans. Check with your local council before you start.
Enjoying your pool and hot tub for years to come
Bringing both into your garden is a lovely way to create a space the whole family will use through every season. The pool gives you room to swim and play. The spa gives you warmth, rest and a reason to head outside even when it’s cold.
The key is planning them together. Think about where each will sit, how you’ll move between them, how they’ll be heated and covered, and how everyone will stay safe. Get those things right and the two will feel like they were always meant to be there.
