A pool that changes depth sounds like magic
Imagine a pool that’s shallow enough for toddlers to paddle in the morning, deep enough for a proper swim at lunchtime, and completely hidden under a smart terrace by the evening. It sounds like something from a film, but adjustable floors really do exist.
A movable pool floor is a platform inside the pool that can be raised or lowered. At its lowest, you have a normal pool. As it rises, the water gets shallower. In some designs it can come right up to the surface, so the pool disappears and the space becomes a usable floor.
It’s a clever idea, and it’s easy to see the appeal. In this guide we’ll explain how these systems generally work, who tends to choose them, and what’s involved. We’ll also be honest about the practical side, and share some simpler ways to get a flexible, family-friendly pool.
A quick note from us
At HiLife we install one-piece pools, swim spas and spas. We don’t make or fit adjustable floors. We think it’s still worth explaining them fairly, so you can make a well-informed choice.
How a movable pool floor works
The details vary from one system to another, but the principle is broadly the same.
The platform
A rigid, flat platform sits inside the pool. It’s usually a strong frame with a surface on top that you can walk on comfortably. Water can pass through or around it, so the pool still circulates and filters properly.
The lifting system
Something has to raise and lower that platform. Common approaches include:
- Hydraulic rams set into the pool floor
- Mechanical systems using cables, chains or screws
- Buoyancy systems that use air or water to change how the platform floats
The platform is usually controlled from a panel, a key switch or a remote. Many systems stop at set depths, so you can choose the depth you need.
Built into the structure
Because the machinery lives in or below the pool, the design has to be planned from the very start. It isn’t something that can simply be dropped into an existing pool. The structure, pipework and plant room all have to work around it.
Why people choose a movable pool floor
There are some genuinely good reasons people fall in love with this idea.
One pool for every age
A shallow setting is great for young children learning to swim or for gentle exercise. A deeper setting suits confident swimmers. Families with a wide range of ages can find that appealing.
Therapy and exercise
Being able to set the exact depth is helpful for water-based exercise and rehabilitation. Some therapy pools use adjustable floors for this reason. Standing at chest or waist height lets people move freely while the water supports their weight.
Reclaiming the space
In homes where space is tight, a floor that rises to the surface can turn the pool into a room or terrace. It can host a party, a dining table or simply open space when nobody is swimming.
Safety when not in use
When a moving floor is raised to the top, there’s no open water. For some families that’s a big part of the appeal, though it’s never a replacement for supervision.
If a fixed design suits you better, our guide to choosing a swimming pool floor covers depth, slope and finish.
What’s involved in fitting a movable pool floor
This is where it helps to be realistic. Adjustable floors are impressive, but they’re a serious piece of engineering.
Design from day one
The pool, structure and machinery all need to be designed together, often by specialist engineers. It usually works best in a new build or a major renovation.
More moving parts
Anything with motors, hydraulics or mechanisms needs regular checks and servicing. Seals, sensors and controls all have to be kept in good order. It’s worth asking any supplier about service plans and how repairs are handled.
Weight and structure
Water is heavy, and so is a platform strong enough to walk on. The surrounding structure has to support both, plus the lifting system and the people using it.
Access for maintenance
Engineers need to reach the mechanism safely. That often means a dedicated plant area close to the pool. Good access makes servicing far easier over the years. It’s also worth asking how quickly a specialist can attend if the platform ever stops working, as you won’t want the pool out of action for long.
Planning and regulations
Structural and electrical work will usually need building regulations approval. Planning permission may apply depending on the wider project. Always check with your local council or building control.
What it’s like to use an adjustable floor day to day
It helps to picture ordinary life with one of these systems, rather than just the showpiece moment when the floor rises.
Changing the depth
Most systems move slowly and steadily. You choose a setting, wait for the platform to reach it, then get in. Safety sensors normally stop movement if something is in the way. Nobody should be in the water while the floor is moving unless the maker says it’s safe.
The feel underfoot
Standing on a platform feels a little different to standing on a solid pool floor. Surfaces are usually textured for grip. Some people barely notice the difference, while others find it takes a swim or two to get used to.
Keeping it clean
Debris can settle on and under the platform. Cleaning routines vary, so ask how the underside is kept clear and whether a robotic cleaner can reach everywhere it needs to.
When the floor is up
With a movable pool floor raised to the surface, the space can be used like a terrace or room. It’s worth checking how much weight it can carry and whether furniture can be left on it.
Things to weigh up before you decide
A moving floor is a wonderful feature for the right project. It helps to think about how you’ll really use the pool before you commit. Be honest with yourself about how often the depth will change in real life.
Questions to ask yourself
- How often will we actually change the depth?
- Do we need the pool to disappear, or just to have a shallow area?
- Is this a new build, or are we working with an existing home?
- How do we feel about ongoing servicing of the mechanism?
- Would a simpler design give us most of what we want?
Thinking about the long term
A pool is something you’ll hopefully enjoy for many years. Think about how your needs might change. Young children grow into teenagers who want to swim lengths or jump in. Grandparents may visit and prefer gentle steps and warm water. A design that copes well with those changes will serve you better than one built around a single stage of family life.
Noise and running
Lifting systems make some sound as they move, and hydraulic or electric equipment uses power. Neither is usually a problem, but it’s worth asking a specialist to explain what to expect before you commit.
Comparing specialists
If you decide an adjustable floor is right for you, talk to a specialist who designs and builds them. Ask to see past projects, speak to their customers if you can, and understand exactly what aftercare is included.
A moving floor is just one kind of retractable pool, and for many families a retractable cover gives similar flexibility with far less engineering.
Simpler ways to get a flexible, family-friendly pool
Often, what people really want from an adjustable floor is flexibility. A pool that suits little ones and keen swimmers alike, is safe when it’s not in use, and looks lovely in the garden. There are other ways to get much of that without the engineering of a movable pool floor.
Choose a thoughtful depth profile
A well-designed pool can include a shallow end, a gently sloping floor and a deeper area for swimming. Wide steps and moulded benches give children and less confident swimmers plenty of places to sit, stand and play. Our guide to swimming pool safety has more ideas for family pools.
Add a safety cover
A strong automatic cover can close over the water at the touch of a button when the pool isn’t in use. It keeps leaves out, holds heat in and adds a layer of safety. Our guide to automatic pool covers explains the different types.
Consider a compact design
If space is the main concern, a smaller pool or a swim spa might give you everything you need without a complicated mechanism. Our guide to the small garden pool is a good place to start.
A one-piece pool with built-in features
One-piece pools arrive as a single seamless shell, with steps, benches and ledges already moulded in. They’re quick to install, strong and pleasant to use. You can explore our full range of pools to see the different shapes, sizes and depths available. Talk to us about which layout would suit your family best.
Living with a pool that works for everyone
Whatever you choose, the best pools are the ones families actually use. A little thought about how your household spends its time makes a big difference. That’s true for a movable pool floor, a simple garden pool or a swim spa on the terrace.
For young children
Shallow steps and ledges let little ones splash safely while staying close to an adult. Warm water helps them feel comfortable and confident. A shallow ledge along one side gives them their own little area to play, while grown-ups swim nearby. Always supervise children around water, and teach them simple pool rules from the start.
For keen swimmers
A good length, a sensible depth and a heated pool with a cover make regular swimming a pleasure. Some people also add a current system for continuous swimming.
For relaxing
Benches, gentle lighting and a comfortable water temperature turn a pool into a place to unwind at the end of the day.
For the whole year
Heating, a cover and perhaps an enclosure can stretch your swimming season well beyond summer. That means far more value from your pool.
Everyday care
Whatever style you choose, keep the water tested and balanced, clean the filter as advised and use a cover when the pool isn’t in use. If you use chemicals, follow the label, wear gloves and eye protection, never mix chemicals, and always add chemical to water rather than water to chemical. Keep swimmers out until the water is balanced, and store chemicals away from children and pets.
Moving floor questions we get asked a lot
Can a movable floor be added to an existing pool?
It’s usually very difficult, because the mechanism needs to be designed into the structure from the start. A specialist would need to assess the pool.
Is the water still filtered with the floor raised?
Systems are designed so water can keep circulating, but the details vary. It’s a good question to ask any specialist.
Does HiLife install adjustable floors?
We don’t. We install one-piece pools, swim spas and spas, and we’re always happy to talk through simpler ways to get a flexible pool.
Is a raised floor a safety cover?
It can reduce open water, but it should never replace proper supervision or other safety measures.
Are adjustable floors high maintenance?
They have more moving parts than a standard pool, so they need regular professional servicing.
What’s the simplest way to have a pool for all ages?
A well-planned depth profile with wide steps and benches, plus a good cover, suits most families very well.
Deciding if a movable pool floor is right for you
Adjustable floors are clever and can be wonderful in the right home. For many families, though, a thoughtfully designed pool with shallow areas, benches and a good cover gives them almost everything they wanted, with far less complexity.
