Soft or solid is often the first big choice
Most people start their pool journey with a simple question. Do we go for something quick and inflatable, or do we want something more solid? That is usually the moment hard sided pools come into the conversation.
The phrase covers quite a wide range. At one end you have rigid above-ground kits with metal or resin walls. At the other you have permanent in-ground shells that sit flush with the patio and last for decades. What they share is a structure that holds its own shape, rather than relying on air or water pressure.
In this guide we explain the main types, what they do well, where they struggle and whether they are worth the extra investment. HiLife Pools installs one-piece pools and swim spas, which are one kind of rigid pool. We will be clear about where they fit and where other options might suit you better.
What counts as a hard sided pool?
Put simply, the walls are rigid. They do not flop, sag or need inflating. They stand up by themselves or are held firmly by the ground around them.
The main families
- Rigid above-ground kits with steel, aluminium or resin walls and a vinyl liner inside.
- Semi-sunken kits, partly buried and finished with decking.
- In-ground liner pools built with panels or blockwork, then lined.
- Concrete pools, formed on site and then rendered, tiled or painted.
- One-piece pools, made in a factory as a single seamless shell and craned into place.
Soft sided pools for comparison
Soft sided pools include inflatable paddling pools and frame pools with fabric walls held up by poles. They are cheap, quick to set up and easy to pack away. They are also easily punctured, hard to heat and usually only last a few summers. For a bit of fun on a hot weekend they are great. For regular swimming, most families soon want something sturdier.
Soft pools also need a very flat, clear patch of lawn, and they can leave a yellow square behind when they come down. Filtration is usually basic, so the water can turn cloudy quickly in warm weather. Many people end up emptying and refilling them more often than they expected.
Why hard sided pools appeal to so many families
There is a reason people move on from inflatables. A solid structure changes how a pool feels and how long it lasts.
Stronger and safer walls
Rigid walls do not bow when someone leans on them or climbs in and out. That makes the pool feel more secure, especially with lively children. It also makes it easier to add proper steps, ladders and covers.
Better for heating
A solid pool can be fitted with a proper pump, filter and heater. Pair that with a good cover and you can enjoy warm water for a much longer season. Soft pools rarely hold heat well enough to make heating worthwhile.
Longer life
Even the simpler rigid kits generally last much longer than an inflatable. Permanent in-ground versions can last for many years with sensible care, and they become a real feature of the home.
Better water quality
With proper filtration and a regular care routine, it is much easier to keep the water clear and balanced. That makes swimming more pleasant and reduces the risk of cloudy or green water.
Room to add extras
Once you have a solid structure, you can add the things that make a pool a joy to use. Underwater lighting, a proper safety cover, wider steps and comfortable seating ledges all become possible. Many owners also like to add heating controls they can check from their phone, so the water is ready when they are.
Many families start with a softer option first, and our guide to the temporary swimming pool explains why that often doesn’t last.
The different types of hard sided pools compared
Each family of rigid pool has its own strengths. Here is a plain English look at each one.
Rigid above-ground kits
These are the most affordable way to get a solid pool. Metal or resin walls are bolted together on a level base, and a liner holds the water. They go up fairly quickly and can look smart with decking around them. The trade-off is that the liner will need replacing from time to time, and the pool tends to look like an add-on rather than part of the garden. Our guide to the above ground pool covers this in more depth.
In-ground liner pools
Here the walls are built below ground, often from panels or blockwork, and a vinyl liner forms the waterproof layer. They can be made in many shapes and sizes. They sit flush with the patio and look much more permanent. The liner still needs replacing periodically, and repairs can be fiddly.
Concrete pools
Concrete gives almost total design freedom. The shell is formed on site, then finished with render, tiles or another surface. It is very strong, but it is also a longer, more involved build. Surfaces may need refurbishing over the years, and the project usually takes many weeks. HiLife does not build concrete pools, but talk to us about how a one-piece pool compares if you are weighing it up.
One-piece pools
A one-piece pool is a factory-made hard shell pool. The whole shell, including steps, benches and ledges, is moulded as one seamless unit. It is delivered to your home, craned into a prepared hole and then connected up and surrounded with paving. This is what we install at HiLife Pools.
For a closer look at one of these, read our article on the steel wall pool.
Among the rigid options, a resin swimming pool stands out because the whole shell is formed in one go with no joins to seal.
Are hard sided pools worth the extra cost?
This is the question most people really want answered. We do not give figures in our guides, because every garden is different. We can share how to think about value.
Think in years, not summers
A cheap inflatable might last one or two seasons. A rigid kit may last several years, with liner changes along the way. A permanent in-ground shell can give you many years of use. When you spread the cost over the time you will actually use it, the more solid options often look far more sensible.
Think about how you will use it
- If you want an occasional splash on hot days, a soft pool may be enough.
- If you want to swim regularly, exercise or entertain, a rigid pool makes much more sense.
- If you want a pool that adds to the feel and appeal of your home, a permanent shell is usually the way to go.
Think about running and care
A solid pool can be heated, covered and filtered properly. That makes upkeep more predictable and the water nicer to swim in. A good cover also helps keep heat in and debris out.
Think about how long you will stay
If you expect to move in a couple of years, a simpler option may make more sense. If this is your long-term family home, a permanent pool becomes part of daily life for years to come. Many owners tell us it changed how they use their garden completely, from early morning swims to summer parties.
Think about the garden
A permanent pool needs space, access for a digger and possibly a crane, and some thought about planning and landscaping. A rigid kit needs a level base and a clear area. Your installer should walk through all of this with you at the first visit.
Why a one-piece hard shell pool is worth a look
We are naturally biased, but we also think one-piece pools solve many of the frustrations people have with other rigid options. Here is why.
No liner to replace
The surface is a hard-wearing gelcoat that is part of the shell. There is no vinyl to wrinkle, fade or puncture.
Smooth and comfortable
The surface is smooth underfoot and gentle on skin. Steps and benches are moulded in, so there are no sharp edges or joins.
Fast, tidy installation
Because the shell arrives finished, the installation is usually much quicker than a concrete build. Groundwork, connection and landscaping still take time, but the pool itself goes in efficiently.
Easy to heat and cover
A one-piece pool can be insulated and paired with heating, lighting and a cover as part of the project. That helps you enjoy a longer swimming season.
A choice of shapes and sizes
One-piece pools come in a wide range of shapes and sizes, from compact plunge pools to generous family pools and long lap designs. Many include built-in benches, wide entry steps and shallow ledges for sitting or for little ones to play on. Finishes vary too, from bright blues to softer greys that give a more natural, modern look.
Straightforward care
The smooth surface is easy to clean, and the equipment is familiar to pool technicians. We also offer aftercare, servicing and repairs, so help is never far away.
To learn more about how they are made, see our guide to the one-piece swimming pool.
We cover this in more detail in our article on the prefabricated swimming pool.
Planning and safety for any rigid pool
A few points apply whichever type you choose.
Planning permission and building regulations
Many garden pools fall under permitted development, but it depends on size, position and whether the property is listed or in a conservation area. Pool buildings and electrical work may also need to meet building regulations. Always check with your local council and building control before you start.
Access and groundwork
Permanent hard sided pools need a proper hole, a solid base and good drainage around them. Your installer will want to see how a digger can reach the garden, where the spoil will go and whether a crane can lift a shell over the house or a side wall. Ground conditions matter as well. Clay, a high water table or a sloping plot can all be managed, but they need planning from the start.
Safety around water
Supervise children at all times. Consider a safety cover, fencing or a lockable gate. Keep a float or reaching pole nearby, and make sure everyone knows the pool rules.
Chemicals
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 safely away from children and pets.
Hard sided pools questions we get asked a lot
Are rigid pools better than inflatables?
For regular use, yes. They are stronger, easier to heat and last much longer. Inflatables are fine for a quick splash, but they are not built for the long term.
What is a hard shell pool?
It usually means a pool made as a single rigid shell, rather than built from panels with a liner. One-piece pools are a common example.
Can I leave a rigid pool up all year?
Most rigid pools are designed to stay in place all year. They need winterising or a winter routine to protect the water and equipment through the colder months.
Do I need planning permission?
Often not, but it depends on your property and the size and position of the pool. Check with your local council before you commit.
Does HiLife install above-ground kits?
No. We install one-piece pools and swim spas, with heating, covers, lighting and equipment as part of the project. Talk to us about which option might suit your garden.
How long does a one-piece pool take to install?
The pool itself goes in quickly once the hole is ready. The overall timescale depends on groundwork, access and landscaping, and we will give you a realistic estimate.
Choosing the right hard sided pools for your home
Rigid pools are a big step up from inflatables. They are stronger, warmer, cleaner and far longer lasting. The right type depends on your budget, your garden and how you want to use the water.
If you want something permanent, seamless and low fuss, a one-piece hard shell pool is well worth considering. You can explore our full range of pools and swim spas, and we are always happy to come and look at your garden with you.
