Serious swimmers often dream about training at home
We speak to a lot of keen swimmers. Some are club members, some are triathletes, and some are parents of children who train several mornings a week. Many of them share the same thought. Wouldn’t it be wonderful to train at home, without the early drive to the leisure centre?
That often leads to questions about a competition swimming pool and what it would take to have one in the garden. It’s a fair question. If you swim seriously, you want water that feels like the real thing.
In this guide we’ll explain what the sizes used for racing actually are, why they are set the way they are, and what that means for a home. We’ll also look at the practical alternatives that give you proper training without needing a garden the size of a sports centre.
A quick note before we start
HiLife installs one-piece pools and swim spas for homes. We don’t build full racing venues. What we can do is help you find the right training setup for your space and your goals, and we’ll be honest about what fits.
What makes a competition swimming pool different
A pool used for official races has to be the same everywhere. That’s the whole point. A time swum in one venue needs to mean the same thing as a time swum in another, so the governing bodies of the sport set clear standards for length, lane width, depth and more.
These standards cover far more than the basic shape. They include the start blocks, the lane ropes, the markings on the floor and walls, the water temperature and even the lighting. Everything is there to make racing fair and safe.
The two lengths you’ll hear about
Most races take place in one of two pool lengths.
- Long course, which is 50 metres. This is the length you see at major international championships.
- Short course, which is 25 metres. Many local leisure centres and club venues use this length, and plenty of galas are swum in it.
Both lengths have to be accurate to within a very small tolerance, often measured with touch pads in place. That level of precision matters for records, but it is a world away from what most home swimmers need.
Lanes and width
Racing pools are divided into lanes, usually eight or ten for major events, with each lane around 2.5 metres wide. The outer lanes often have extra space beside them to calm the waves bouncing off the side walls. A full size 50 metre venue with ten lanes is roughly the footprint of a small building.
Depth, temperature and the finer details
Depth is one of the less obvious parts of a racing venue. Deeper water helps reduce turbulence, so the waves created by swimmers settle more quickly. That’s one reason modern elite pools are often two metres deep or more along their whole length.
Depth also matters for safety at the start. Swimmers dive in from blocks, so there has to be enough water below them. Home pools, by contrast, are usually designed with no diving in mind.
Water temperature and conditions
Racing water is kept within a fairly narrow temperature band. It’s cooler than many people like for a relaxing swim, because hard work in warm water can feel exhausting. For home use, most families prefer something warmer and more comfortable, and a good heating system lets you choose.
Markings, walls and turns
Racing venues have dark lines on the floor down the middle of each lane, with a T shape near each end so swimmers know the wall is coming. The end walls are solid and flat for tumble turns and push offs. These are small details, but they tell you a lot about how carefully a racing venue is set up.
- Lane lines on the floor help swimmers stay straight.
- Target marks on the end walls line up with the lane lines.
- Backstroke flags hang across the pool near each end as a warning.
- Wave reducing lane ropes help keep the water calm.
Do you really need a competition swimming pool at home?
For almost every family, the honest answer is no. Very few UK gardens have room for a 25 metre pool, let alone a 50 metre one. Even where the space exists, the build, the planning and the ongoing care are on a very different scale from a family pool.
The good news is that most swimmers don’t need official pool dimensions to train well. What they need is enough length to swim comfortably, enough width to swim without clipping the sides, and a depth that feels right for their stroke and their turns.
What home training usually looks like
Think about the kind of sessions you swim. A club swimmer might want drills, technique work and steady aerobic sets. A triathlete might want long, unbroken swims at race pace. A masters swimmer might just want to keep fit and enjoy the water.
Each of those can be done in a smaller space than you might expect, as long as the pool is designed for swimming rather than just splashing about.
Length that feels like proper swimming
In a very short pool, you spend most of your time turning. As the length increases, you get more strokes between walls and the session starts to feel like real training. Our guide to the lap pool covers this in more detail, including rough lengths that suit different swimmers.
Smart alternatives for training at home
If you want serious swimming at home without building a full competition swimming pool, there are a few routes worth thinking about. Each has its strengths, and the right one depends on your garden, your budget and how you like to swim.
A long one-piece pool
A one-piece pool arrives as a single shell, made in a factory to a high standard, and is craned into place. Longer, slimmer designs suit lane swimming beautifully. Because the shell is made in controlled conditions, the finish is smooth and consistent, and installation is usually quicker than a site built pool.
You won’t get racing length, but you can get a pool that feels good for steady sets and technique work. Pair it with heating and a cover and you can swim for much of the year.
A swim spa with a current
A swim spa uses a powerful current so you can swim continuously without ever reaching a wall. It’s a bit like a treadmill for swimming. You can turn the current up for a hard session or down for gentle recovery work, and it takes up far less garden space than a long pool.
Many triathletes love this approach because it lets them hold a steady stroke rate for as long as they like. It also doubles as a warm, relaxing spa once training is done. Our swim spa guide explains how they work and what to look for.
Short, sharp pool sessions
Some swimmers combine a home pool or swim spa with regular club sessions at a local competition swimming pool. They do their technique, drills and recovery work at home, then head to the club for racing specific sets and starts. That mix can work really well and keeps your home setup realistic.
Our guide to the sports pool has more ideas for setting up a home pool around training, fitness and games.
Planning the right size for your garden
Before you fall in love with a particular size, it’s worth stepping back and looking at the whole picture. The pool itself is only part of the space you need.
Think about the surrounding area
A pool needs room around it for access, paving, planting and a spot to sit. You also need somewhere sensible for the plant equipment, such as the pump, filter and heater. Crane access for a one-piece shell is another factor, so we’ll always check this at the survey.
- Measure the space you have, including any slopes or awkward corners.
- Check the route for access and any overhead cables or trees.
- Think about where the sun falls through the day.
- Consider how the pool will look from the house.
Planning and regulations
Whether you need planning permission depends on the size, the location and your property. It’s always wise to check with your local council before you commit. Our guide to swimming pool planning permission explains the general picture, and building control may also need to be involved depending on the work.
Getting pool dimensions right for you
The best pool dimensions for your home are the ones that match how you’ll really use it. A keen swimmer, a family with young children and a couple who want to relax all need something a little different. That’s why we like to talk it through properly before recommending anything. Take a look at our range of one-piece pools and swim spas to get a feel for the shapes and sizes available.
Our guide to the 15m swimming pool is a good next read if you want serious training lengths in a pool that still fits a family garden.
Keeping a training pool in great condition
Whatever you choose, good water care makes every swim more pleasant. Clear, balanced water is kinder to your skin and eyes, and it protects the pool and equipment too.
The simple routine
Most of the work is little and often. Skim the surface, keep an eye on the filter, and test the water regularly so you can catch small changes early.
- Test the water a few times a week during the swimming season.
- Keep the filter clean so the water stays clear.
- Use a cover when the pool isn’t in use to keep out leaves and hold in heat.
- Book a regular service so a professional can check the equipment.
Handling chemicals safely
If you look after the water yourself, always follow the label on any product. Wear gloves and eye protection, never mix chemicals together, and always add chemical to water, never water to chemical. Keep swimmers out until the water is balanced again, and store everything away from children and pets.
We also offer aftercare, servicing and repairs, so if you’d rather leave the water care to us, that’s fine too.
Competition swimming pool questions we get asked a lot
How long is an Olympic pool?
An Olympic pool is 50 metres long. It usually has eight or ten lanes and is often at least two metres deep along its full length.
Can I have a 25 metre pool in my garden?
It’s possible on a very large plot, but it’s unusual for a home. The build, planning and upkeep are on a much bigger scale, so most keen swimmers choose a shorter lap style pool or a swim spa instead.
Is a swim spa good enough for serious training?
For many swimmers, yes. A good current lets you swim continuously at a steady pace, which suits aerobic sets and technique work. You won’t practise turns, so some people combine it with club sessions.
How wide should a home training pool be?
It depends on your stroke, but you want enough room to swim freely without touching the sides. We’ll suggest a sensible width once we know how you swim.
Can I dive into a home pool?
Most home pools are not designed for diving and we’d always advise against it. Diving needs a lot of depth and space, and entering feet first is much safer.
Do I need planning permission for a long pool?
It depends on your property and the size of the pool. Always check with your local council before going ahead.
Finding your own version of a competition swimming pool
You don’t need a racing venue to swim well at home. What matters is a pool or swim spa that suits your stroke, your training and your garden. With the right design, you can swim every day and enjoy it every time.
We’d love to help you work out what fits. A long one-piece pool or a swim spa with a strong current can both work brilliantly, and we’ll give you honest advice and a tailored quote. Talk to us about your training goals too, so the finished pool feels right from the very first length.
