Coastline — 10m × 4.4m
Big presence, bold design.
Ten metres of water and 4.4 metres of width — the Coastline is the model for a section with room to give and a household that actually swims. Getting in is unhurried: a wide multi-step entry eases you down into 1.20 m rather than tipping you in. Getting out is much the same, and if you would rather not, there are seats at both ends, mirrored so the deep end never has to be swum around. It runs from 1.20 m to 1.90 m at the deep end (shell heights) and holds over 35,000 litres — which makes it a consented pool, and Bayside runs that process for you.
Go Big, Go Bold
The Coastline turns a generous section into a resort-scale backyard — ten metres of water, seating at both ends, and room for a proper gathering.
Ten Metres of Water
Length is the whole argument for the Coastline. Ten metres wall to wall with 4.4 metres of width means a length is a length rather than a few strokes and a turn — and three or four swimmers in the water still have somewhere to be.
Seats at Both Ends
The deep-end seats are mirrored, one at each end, so there is somewhere to sit at either end of the pool and nothing left in the middle to swim around. Grown-ups supervising one end, teenagers holding court at the other.
A Descent You Choose
You enter the Coastline down a wide multi-step entry, not over a wall or off a ladder. Toddlers can sit in the shallows at 1.20 m, grandparents can take the steps at their own pace, and nobody is lowered in.
Why the Coastline Is Different
Every model in the 4.4 metre family is wide. The Coastline is the one that is genuinely long, and that is the difference between a backyard pool and a swimming pool: ten metres of water line you can swim rather than wade, with the seating pushed to both ends so it stays out of your way. It is also why it runs from 1.20 m to 1.90 m (shell heights) and holds over 35,000 litres. At that volume a building consent applies — and Bayside runs that process rather than handing it back to you.
Coastline — Where Length Meets Lifestyle
This is the pool for a family that swims. Ten metres is long enough for lengths before the day starts, and 4.4 metres of width is wide enough that four people in the water are not apologising to each other. Seats at both ends give the non-swimmers somewhere proper to sit, and the wide entry keeps the shallow end sociable instead of a steep drop. The proportions suit contemporary and architectural homes, where the pool reads as part of the design rather than something added to the yard later — and it needs a large section to do that properly.

Building Consent Applies — and Bayside Manages It
At over 35,000 litres the Coastline is above the threshold where a building consent is required. That is a process to run, not a reason to buy a smaller pool.
Over the threshold — the consent work sits with us
Over 35,000 litres, the Coastline is a consented pool: a building consent is required, and Bayside manages that process — the documentation, the application and the inspections that follow — so it is our job rather than yours. There is a step before the digger arrives, and we run it. What does not change is the shell. Every Coastline is manufactured to AS 1838 / NZS AS 1838, the design and fabrication standard for premoulded fibreglass swimming pools, and installed to AS 1839 / NZS AS 1839. Pool fencing requirements still apply (Building Code clause F9), and your local installer walks you through what your property needs.
Your ground, your access, your boundary — that is the engineering
A standard shell is the starting point, not the whole answer. Ground conditions, the water table, how the pool sits against the boundary, retaining and landscaping all feed into the site-specific design for a 10 metre pool — and so does access. If the 1,800 mm wide 5 tonne machine cannot reach the backyard, a 1.8 tonne digger does the work instead, and some sections need the shell craned over a fence or the house. Your local installer works all of that out and prices your property before anything is committed.
What a standard excavation covers — and what varies
Every Bayside quote includes a standard dig-out: machinery transported to and from site, cover sheets if spoil is piled on the driveway, gardens and pathways protected where necessary, the pool area excavated to the specified dimensions, excavated material loaded onto trucks where it has to leave the property, and a clean-up and water-blast at the end. What varies is your site — how far spoil has to travel, whether stormwater or services need relocating, ground levels being raised or lowered, topsoil and ready-lawn preparation, trees within the pool area, and concrete or landscaping. Those extras are priced at Bayside’s standard rates and confirmed with you before they are carried out. Full landscaping packages are available within specific service areas; ask your installer.

Design Your PoolCoastline Frequently Asked Questions
The practical answers, and a few you were actually wondering about.
Does the Coastline need building consent?
Yes. At over 35,000 litres the Coastline is above the 35,000 litre threshold where a building consent is required. Bayside manages that process — documentation, the application and the inspections that follow — so it is our job rather than yours. There is a step before the digger arrives, and we run it.
How deep is the Coastline?
1.20 m at the shallow end, sloping down to 1.90 m at the deep end, reached by a wide multi-step entry. Bayside publishes depth as shell height — top of the shell down to the base, as dimensioned on the engineering drawing — so the figure matches the drawing and your specification sheet.
How much water does it hold?
Over 35,000 litres, which is the published figure for this model. That volume is also what decides its consent status, so plan for heating and filtration to be sized to the pool rather than assumed: your installer matches the package to your volume and your cover.
Is the Coastline a real lap pool?
At 10 metres long and 4.4 metres wide, with the seating tucked into both ends rather than the middle, you get a clean water line to swim. It is not a 25 metre training lane, but it is the model in the range where swimming lengths is the obvious thing to do rather than the ambitious one.
How much does it cost to heat?
We do not publish running costs — they depend on your heat pump, your cover, your set temperature and the length of your season. What is certain is that over 35,000 litres needs a properly sized heat pump and a cover to hold temperature, and your local installer sizes that package around how you intend to use the pool.
What size section does the Coastline need?
Enough for the setbacks and fencing the law requires, plus machinery access to dig and room to place the shell. Send us photos, a site plan or a few measurements and we will tell you honestly whether it fits — including whether the 1,800 mm machine can reach the backyard or a smaller digger is needed.
How does a 10 metre shell get to my property?
Delivery is to the bottom of your driveway on the back of a large truck. If your site needs a hiab or a crane to place the shell, and machinery to lift it off the truck, that is arranged between you and your installer before the day — and if the shell has to be craned over a fence or the house, it is priced up front with everything else.
What can change on my site?
A standard dig-out is included: machinery transport, cover sheets if spoil is stacked on the driveway, protection for gardens and paths, excavation to the specified dimensions, truck loading of material that has to leave, and a clean-up and water-blast at the end. Beyond that your property decides — distance for spoil, services or stormwater to relocate, ground levels, topsoil and lawn preparation, trees, concrete and landscaping. Every variation is confirmed with you before it is carried out.
What standard are Bayside pools built to?
The shells are manufactured to AS 1838 / NZS AS 1838 — Swimming pools: premoulded fibre-reinforced plastics, design and fabrication — and installed to AS 1839 / NZS AS 1839. Those standards set the layer build-up, the loads the shell has to carry, and the curing and finish checks before a pool leaves the factory. The Coastline is built to them, and as a consented pool the work is inspected as well.
How is the shell actually built?
By hand, in layers. From the water out: the gelcoat, which is the coloured surface you swim against; the corrosion barrier, a resin-rich layer that keeps water out of the laminate and resists osmotic blistering; the structural glass laminate of chopped and woven glass that carries the load and holds the shape; core and rib reinforcement stiffening the walls and the top flange; and an outer sealing coat against ground moisture. The swimming surface is finished with ChlorShield.
How thick are the shells?
It depends where you measure, and deliberately so. Walls, floor, steps and corners each carry different loads, so each is laminated differently: as a site-wide guide our wall laminates run around 7–9 mm, and corners and steps run 12–15 mm where the loads concentrate, with a longer shell laminated heavier than a short one. Ask us for the layer specification in writing and we will put the Coastline figures in front of you.
What maintenance does a pool this size need?
The same routine as any Bayside pool: balanced water, a clean filter and the surface kept clean. The smooth fibreglass finish does not hold grime the way tile or pebble can, and Q360 in-floor cleaning can be added if you would rather not vacuum at all. A bigger volume means more litres to keep balanced, not a different routine.
How do you know my pool was built right?
Every Coastline shell is moulded in our Whakatane factory rather than shipped in from overseas, and it is inspected and signed off at each stage — lay-up, curing, gelcoat and final finish — with the build recorded against that individual shell. You are welcome to visit the factory and watch one being made.
Could I actually train for something in this?
Ten metres gives you a proper push-off and a few good strokes, not a 25 metre lane — so it is training in the honest sense: fitness swimming, technique work and a lot of lengths before breakfast. You will be turning often, which is exactly what the seats at both ends are for when you stop.
How many people fit on the seats at once?
The seats are mirrored, one at each end, so you have two separate sitting areas rather than one crowded bench. Across a 4.4 metre wide pool that is a lot of in-water seating — enough for the adults to sit out a game of Marco Polo in comfort while the kids use the other ten metres.
Will it be the biggest pool on the street?
Quite possibly. If it is not, someone on your street bought the Big Bertha, which runs to 12 × 4.4 m. Either way you become the house with the pool, and the neighbours will work that out in the first warm week.
Do we still need to go to the beach?
Less often than you used to, which is the real point of a pool this size. Over 35,000 litres of water, seating at both ends, and a swim season that starts earlier and finishes later than the ocean — with no sand in the car afterwards.
Where We Install the Coastline
Bayside pools are installed through a nationwide dealer network. Ask about the dealer in your region.
Auckland
Auckland is where a 10 metre pool has to earn its ground. Where the section is long enough, the Coastline runs down the yard with the house, the lawn and the side path all still usable — 4.4 metres of width is what makes that arithmetic work. Where access rather than space is the constraint, your installer settles the machinery question first: the 1,800 mm machine if it reaches, a smaller digger if it does not, a crane if the shell has to fly over the house.
Tauranga & Bay of Plenty
The Coastline is moulded about an hour up the road from Tauranga, in our Whakatane factory, so plenty of Bay of Plenty buyers come and watch their shell come out of the mould. Around Tauranga, Mount Maunganui and Papamoa the sections are generous, and a 10 × 4.4 m pool leaves real room for a deck and planting around it. Coastal ground and access still vary, so the dig is priced for your property.
Hamilton & the Waikato
A Waikato winter asks every pool the same question: how much water are you heating? The Coastline is the largest of the 4.4 metre models, so the heat pump is sized to that volume and a cover earns its keep from autumn onwards. Heavier ground and higher water tables are common through the region, and any variation to the standard excavation is confirmed with you before work starts.
Wellington
Terraced, tight and windy — Wellington is where access decides the job rather than the pool. A 10 metre shell is a substantial lift, so if the machine cannot get up the drive it is craned over the fence, arranged and priced up front rather than discovered on the day. Once it is in, the sheltered water and the seats at both ends make the Coastline a pool the household actually uses.
Christchurch & Canterbury
South Island Coastlines travel on the ferry run from Whakatane and arrive exactly as they left the factory. Delivery is to the bottom of your driveway on the back of a large truck, so if the shell needs a hiab or a crane on site — plus machinery to lift it off the truck — that is arranged up front. From there it is a well-worn Canterbury process, to the same shell standard as every other Bayside pool.
Northland & Kerikeri
The Far North stretches the swim season at both ends of the year, which suits a pool you can swim in rather than paddle in. That is the case for ten metres of water line up here, and the wide entry and 1.20 m shallow end suit families with littlies. Sandy ground, coastal air and access that is not always simple are all normal in a Northland install, so the dig is priced on your ground.
Hawke’s Bay & Napier
Napier, Hastings, Waipukurau and the surrounding district get long dry summers and a genuine outdoor living season. The Coastline is shaped around that: seats at both ends for the adults, ten metres of water for the kids, and enough width that a gathering never feels crowded. Much of the region is flat and roomy, which usually makes the excavation the straightforward part of the job.
Gisborne & the East Coast
Gisborne and Tairāwhiti pools come up on the run from the Whakatane factory, and the region’s coastal sections are often longer than they are wide — which is precisely the shape a 10 × 4.4 m pool wants. Ground and access are assessed on site, and any variation to the standard dig is confirmed with you before work begins.
South Auckland
Manukau, Papakura, Pukekohe and the wider Counties area are infill and cross-lease territory, so a 10 metre pool is a decision about access as much as space. Where the section allows, the Coastline’s 4.4 metre width leaves a side path and a strip of lawn. If the 1,800 mm machine will not fit, a smaller digger does the work, and the shell is placed by crane where the site demands it.
