The Pool You've Pictured, In Your Own Garden
Somewhere to swim every morning, a spa to unwind in, or a steam room at the end of the day. We design each one around your home and how you'll use it.



A well-built pool should feel like it was always part of your home. One family-run team designs, builds, tanks and tests every project, and nothing is tiled until it has held water for seven days.
Every Kind Of Water, Under One Roof
- Swimming PoolsBespoke reinforced concrete pools, indoors and out, including basement and splash pools.
- Swim SpasBuilt bespoke in concrete, or a tiled fibreglass unit supplied and installed by us.
- Steam Rooms & SaunasFor homes, hotels and leisure clubs, designed to fit the space you have.
- Refurbishment & ReliningSurvey-led repairs, retiling, new shells and on-site welded liners that bring a tired pool back to life.
- Heating, Ventilation & CoversHeat pumps, pool hall climate control and automatic covers that cut running costs.
- Servicing & MaintenanceOur own engineers keep filtration, heating and water quality running all year.
Whether it's a pool to swim in every morning or a spa to unwind in, one team designs it, builds it and looks after it for years to come.

What Our Clients Say
From pool owners, and the main contractors we build alongside.
Alin was someone we felt we could trust implicitly… The finished pools and spa facilities are simply beautiful. They have transformed our home and created wonderful spaces that we and our family enjoy enormously… we would have absolutely no hesitation in working with him again.
Tuvi KeinanHomeownerIndoor pool, spa and outdoor pool, London From day one, his work force arrived on time (never late) and they approached the work in such a professional manner… If we ever decide to build another pool, Alin would be the first person I would contact to get on board.
Richard SullivanDirector, Swim2swim LtdCommercial swimming pool, Colchester Very professional, friendly, and easy to deal with during the whole time… The pool looks fantastic, and I would definitely recommend Alin Alpin Pools to anyone looking to have a swimming pool built.

Built Properly, Step By Step
- STEP 01

Survey & Design
We visit, measure up and design around your property. For refurbishments we start with a structural survey, so the price is real before work begins.
- STEP 02

The Concrete Shell
Cast, sprayed or ICF concrete, chosen to suit your site and design. Sprayed concrete shells carry a 10-year warranty.
- STEP 03

Waterproofed & Tested
30mm render and 60mm screed laid level to within 1 to 2mm, a mesh-reinforced tanking membrane, then a seven-day water test before a single tile goes on.
- STEP 04

Finished By Hand
Mosaic, glass or porcelain, fixed with pool-grade adhesives and grout. Choose epoxy grout and the tiling warranty runs to five years.
- STEP 05

Looked After For Years
Our own engineers service and maintain what we build, from filtration to heating and covers.

Your Questions, Answered
How much does a pool cost?
It depends entirely on the size, site and finish. We take on everything from repairs to builds of £1 million and more, and there's no minimum job. We quote after a site visit, so the figure reflects your project, not a guess.
What warranty do I get?
On a new build: 10 years on the sprayed concrete shell, 3 years on render and screed, and 3 years on tiling with cement grout, rising to 5 years with epoxy grout. On a refurbishment: 3 years on render, tanking and cement-based grout, extended to 5 years with epoxy grout. The existing structure isn't covered, which is why every refurbishment starts with a survey.
How do you make sure it won't leak?
Every shell is rendered and screeded, then reinforcing mesh goes into every corner and junction before a 3 to 4mm mesh-reinforced tanking membrane goes over the lot. Once that's cured, we fill the pool and leave it for a seven-day water test before any tiling starts.
Can you refurbish my existing pool?
Yes. We start with a survey of the structure and waterproofing. Depending on what we find, we'll repair it, build a new shell inside the old one, rebuild it, or fit a new on-site welded liner.
Where do you work?
We're based in Cheam, Sutton and work across London, Surrey and the rest of England.
How long does a build take?
