Stainless Steel Pools

Crafted from durable marine-grade stainless steel, our Diamant pools offer a sleek, hygienic, and weather-resistant modern aesthetic.

Stainless Steel: A Lifetime Statement

Diamant swimming pools are built from high-quality AISI 316L austenitic stainless steel — an advanced alloy of chromium, nickel, carbon and molybdenum that delivers outstanding strength, versatility and longevity.

The result is a pool that looks as impressive on day one as it does decades later.

Stainless steel's smooth, non-porous surface is naturally hygienic, resistant to frost, heat and UV radiation, and requires minimal maintenance — making it perfectly suited to the demands of the British climate and the expectations of discerning homeowners.

Unlike tiled, lined or concrete pools, a Diamant INOXline pool arrives fully finished as a single precision-manufactured unit. No re-tiling. No liner replacements. No compromise.

With over 25,000 pools completed across Europe since 1994, Diamant is the continent's leading manufacturer of stainless steel pools — and Diamant Bespoke Pools is proud to bring that expertise to UK homes.

Why Choose a Stainless Steel Pool?

Unmatched Material Benefits

Weld-Free Engineering

Setting a new precision standard, INOXline features walls up to 10 meters that are entirely weld-free. This ensures perfectly straight lines, eliminates corrosion risk, and provides a flawless appearance with no unsightly joints.

UV, Frost & Heat Resistant

Stainless steel is fully resistant to frost, heat and UV radiation — making it the perfect choice for the unpredictable British climate. Its colour and structure remain flawless year after year, season after season.

Modern, Exclusive Design

Admired for its avant-garde elegance and lustre, stainless steel is the preferred choice where aesthetics matter most. Its neutral colour integrates harmoniously into any garden or interior setting.

Easy Maintenance

Stainless steel's naturally resistant surface prevents oxidation and keeps pool walls pristine for decades. Cleaning frequency and ongoing costs are significantly lower than tiled, lined or concrete alternatives.

Antibacterial & Hygienic

The smooth, non-porous stainless steel surface prevents bacterial contamination and is effortless to clean. The naturally hygienic surface requires fewer chemicals, keeping your water cleaner for longer.

Recyclable & Eco-Friendly

Diamant INOXline stainless steel pools are 100% recyclable, making them one of the most environmentally responsible pool choices available. Built to last a lifetime, they produce less waste than pools that need relining or resurfacing.

Pool Configurations

Skimmer & Overflow Designs

Skimmer Pool

A swimming pool surrounded by a wooden deck, set in a well-maintained grassy yard with trees and shrubs, under a clear blue sky.

The most popular choice for private gardens. Water is drawn into a collector — the skimmer — from where it is pumped to the filtration system. A simple, efficient system with trouble-free operation and minimal intervention required.

Ideal for those who want the luxury of a stainless steel pool with the simplicity of traditional pool technology.

Overflow Pool

Modern house with a rooftop pool overlooking a field at sunset.

Premium design with water level at the very top edge. Debris is drained into an overflow channel for superior filtration. The result is a sleek, mirror-like water surface that creates a striking visual statement.

Ideal for interior installations, terraces, and architectural projects where design is paramount.

Installation Options

In-Ground or Free-Standing

Standard — In-Ground

The pool is installed on a concrete base and filled with water, while the side walls are backfilled with a dry or semi-dry concrete mix for reinforcement. This is the ideal choice for traditional in-ground installations, allowing the pool to sit flush with surrounding paving, decking or lawn.

Free-Standing — Above-Ground

A self-supporting pool with a solid structural frame, designed for above-ground installation without the need for full excavation. The pool is positioned on a concrete base for correct levelling, making it well suited to terraces, rooftops or sloping sites where in-ground installation is not practical.
