Commercial Swimming Pool Design & Construction in London
Reinforced concrete pools for swim schools, gyms, hotels and spas — designed and built to PWTAG guidance by one team, from structural design to the plant room.
Since 2011 we have delivered more than 50 pools across London and the South East, each backed by a 10-year structural guarantee. For commercial clients we take the whole package: structure, waterproofing, pipework, plant room, finishes and commissioning.
-
One team for design, build and plant room — no gaps between trades
-
Water treatment designed to PWTAG guidance for your bather load
-
10-year structural guarantee on the concrete shell and waterproofing
Commercial pools built for heavy use
A commercial pool runs longer hours, carries more bathers and faces tighter inspection than any private pool. We design for that load from day one: bather-load calculations, turnover rates, balance tank sizing and water treatment that holds up at peak occupancy.
Who we build for
-
Swim schools — teaching pools with warm water, fast turnover for high bather loads, and deck-level edges that make poolside teaching easier. We plan changing, viewing and plant space around your class timetable.
-
Gyms and health clubs — lap and training pools inside working fitness buildings. We coordinate structure, waterproofing and dehumidification with your architect and M&E consultant so the pool hall stays dry, warm and economical to run.
-
Hotels and spas — indoor and outdoor hotel pools, hydrotherapy and spa pools finished in mosaic, porcelain or natural stone. We phase works to keep guest disruption low and hand over with operating manuals and staff training.
-
Plant rooms and refurbishments — new plant rooms and upgrades to existing ones: filtration, UV and chemical dosing, heat pumps and heat recovery, balance tanks and BMS-ready controls. Ideal where an older pool fails water tests or costs too much to heat.

Commercial pool FAQs
Do you design the plant room as well as the pool? Yes. Filtration, UV, dosing, heating and dehumidification are designed and installed by the same team that builds the pool, so there is one point of responsibility.
Do your pools meet PWTAG guidance? Our water treatment and turnover are designed to PWTAG guidance for the bather load and use of each pool.
Can you work with our architect and M&E consultant? Yes. We regularly work to architects’ drawings and coordinate structure, services and finishes with the wider design team.
Can you refurbish a pool while the building stays open? Yes. We phase works and isolate the pool hall so hotels, clubs and gyms can keep trading.
What areas do you cover? London, the Home Counties and the South East.
