Indoor Swimming Pool &
Basement Pool Builders.
Where Architecture
Meets Water.
Preston Pools designs and builds bespoke indoor and basement swimming pools for homes across the North of England, with design, engineering and construction handled by our own team. An indoor pool can sit in a new pool hall, an extension, an outbuilding or beneath the house, and each is planned around ventilation, dehumidification, structure and waterproofing from the first drawing. Contact us to discuss whether your property could take one.
An indoor or basement swimming pool is perhaps the most refined expression of luxury within a private residence. It is a space where architecture, engineering, and atmosphere converge, a room that exists purely for pleasure, wellness, and the quiet indulgence of having something truly exceptional within your own home.
Preston Pools specialises in the design and construction of bespoke indoor swimming pools and basement swimming pools for properties across the North of England. As specialist indoor swimming pool builders, every installation is conceived individually, responding to the unique structural, spatial and aesthetic characteristics of your home.
Basement Swimming Pools
A basement swimming pool asks more of its builder than any other kind of indoor pool. Excavating beneath an existing property — or coordinating a new basement level within a wider build programme — brings structural openings, tanking and waterproofing, drainage, and mechanical services into a single, unforgiving sequence. We plan every basement swimming pool alongside your architect and main contractor from the earliest stage, so that ventilation, dehumidification and plant access are engineered into the structure rather than squeezed in afterwards. The result is a pool that feels inevitable in the space, with none of the compromises that give retrofitted basement pools a bad name.
The Engineering Behind
the Elegance.
Indoor and basement pools present a set of technical challenges that demand specialist expertise. Ventilation and dehumidification must be precisely calibrated to protect both the building fabric and the comfort of the space. Structural loading, waterproofing, and drainage require engineering solutions that are specific to each property. Lighting must be designed to enhance the atmosphere without compromising the architectural integrity of the room.
These are not afterthoughts; they are the foundations of a successful indoor pool. Our engineering team addresses every one of these considerations during the design phase, ensuring that the finished pool performs flawlessly and feels effortless.

Designed
for the Senses.
Beyond the technical precision, an indoor pool should stir something. The play of light across still water. The warmth of natural stone underfoot. The quiet that descends when you step into a space designed entirely for you. Our design team works closely with you to craft these moments — from tile selection and lighting schemes to the proportions of the pool deck and the placement of every water feature.
Light on Water
Layered lighting schemes — concealed coves, underwater LED, and architectural feature lighting that animates the surface throughout the day.
Material Depth
Natural stone, glass mosaic, large-format porcelain — selected for tone, texture, and the way each holds light beneath water.
Acoustic Calm
Considered acoustic treatment and quietly engineered plant rooms create a space that feels still — the way a pool should.
Built Below,
by Specialists.
Basement pools require a level of coordination and specialist knowledge that few companies can offer. We work alongside architects and main contractors from the earliest stages of the build programme, ensuring that structural openings, tanking, mechanical services, and access are all accounted for before construction begins.
Our experience with basement installations across Cheshire, Lancashire, and the wider region means we anticipate challenges before they arise — and resolve them inside the build programme, not after it.

Who builds indoor swimming pools in the North of England?
Preston Pools designs and builds indoor and basement swimming pools for private homes across the North of England. Survey, engineering, construction and finishing are managed by our own team, and we work alongside your architect or main contractor where the pool forms part of a wider build or renovation.
Can I have a swimming pool inside my home?
Yes. An indoor pool can be built in a new pool hall, an extension or an outbuilding, or in a basement beneath the house. The right location depends on structure, ground conditions, ventilation and plant room space, so we begin with a site assessment before recommending a design.
How much does an indoor swimming pool cost in the UK?
The cost of an indoor swimming pool varies widely with size, specification and site, so a meaningful figure only comes from a tailored quote. The pool is only part of the budget: the building around it, ventilation plant and finishes all contribute. Our swimming pool cost guide explains what drives the price.
What makes an indoor pool different to build?
An indoor pool evaporates water into the room, so the building needs properly specified ventilation and dehumidification to protect both comfort and the structure. Waterproofing, drainage, structural loading and plant room space also need to be planned at the start. We address these during design rather than adding them afterwards.
Can a pool be built in an existing basement?
Sometimes. Whether a basement can take a pool depends on a structural assessment, the ground conditions and the available ceiling height. Where there is no basement, the usual route is a new excavation beneath or alongside the house. We would start with a feasibility conversation and a site assessment.
Do I need planning permission for an indoor pool?
It depends on the property. Some internal works may fall within permitted development, but listed buildings, conservation areas and projects involving excavation usually need formal consent. Our team can advise on the position for your home in the early stages, and building regulations approval is a separate step to plan for.
