Insulation Solutions

Designed for Indoor, Outdoor, Commercial & Recirculation

Choose your thermal build — rigid PIR insulation from 25 mm to 150 mm, with 50 mm as standard. Taped, bonded, over-laminated and sealed with our Omnicoat finish, so the whole build holds heat as one continuous shell.

  • 150 mm available From 25 mm to 150 mm — 50 mm is our standard
  • 0.13 W/m²K wall Wall U-value at 150 mm vs 3.0 bare — near-passive
  • 80 % longer heat Held at 50 mm vs a bare build — and a smaller chiller or heater

Choose your thermal build

Insulation is specified by thickness — from 25 mm to 150 mm, with 50 mm as standard. The thicker the board, the lower the heat loss and the smaller the chiller or heater you need. Thicknesses can be mixed across a single build where the project calls for it.

More than a board — a sealed thermal shell

It isn’t just the insulation. The board is taped, bonded into the tub, over-laminated with further layers of glass and resin, rolled, then sealed with Omnicoat — our final, sealed-in coat. The result is one continuous, gap-free shell with no thermal bridging, so the insulation performs at its full value and the whole build works as a single unit. Colour runs all the way through the Omnigel beneath it — never painted on.

Thermal performance by thickness — wall U-value of the finished, Omnicoat-sealed build (lower is better; bare build ≈ 3.0).
Thickness Board R-valuem²K/W Wall U-valueW/m²K Best suited to
Bare build — 3.0 Indoor domestic use — already outperforms acrylic & steel
25 mm 1.10 0.58 Light outdoor & shoulder-season knock-back
50 mm Standard 2.25 0.35 Most projects — holds heat for hours, balanced cost
75 mm 3.40 0.25 Cold-climate outdoor & light commercial
100 mm 4.50 0.19 Year-round outdoor & high-use commercial
120 mm 5.65 0.16 Demanding commercial & continuous recirculation
150 mm 6.80 0.13 Near-passive — maximum heat retention

Figures are for the finished, sealed build (board R plus the over-laminated, Omnicoat-sealed shell). A lower U-value means less heat lost — and a smaller, cheaper-to-run system holding it. Want the numbers for your exact tub, water temperature and climate? The OmniSoak calculator models it live.

Additional insulation walkthrough — up to 13 layers, finished with a fully sealed exterior coating.

Where it earns its keep

  • Indoor

    Optional on standard installs — our 7-layer build already outperforms acrylic and steel for regular bathroom use.

  • Most demand

    Outdoor & cold plunge

    Protects against the temperature delta between your water and the surroundings — prevents condensation, holds heat, survives winters.

  • Commercial

    Hotels, spas, glamping, wellness facilities — additional insulation reduces equipment workload and running costs.

  • Recirculation & filtration

    Tubs paired with chillers, plant rooms or filtration units — extra insulation protects both the tub and the system around it.

Insulation on an Omnitub is specified by thickness — rigid PIR board from 25 mm up to 150 mm, with 50 mm as our standard. The thicker the board, the lower the heat loss, and the smaller the chiller or heater needed to hold temperature.

It is not just the board. The insulation is taped, bonded into the tub, over-laminated with further layers of glass and resin, rolled, then sealed with Omnicoat — our final, sealed-in coat. The result is one continuous, gap-free shell with no thermal bridging, so the insulation performs at its full value and the whole build behaves as a single unit. Colour runs all the way through the Omnigel beneath — it is never painted on.

The most popular choice is 50 mm, which holds water temperature far longer than a bare build — a build that already outperforms acrylic, steel, and most other bath materials on the market. Step up to 100 mm or 150 mm for year-round outdoor use, high-demand commercial settings, or continuous recirculation, and the wall U-value falls towards near-passive levels.

Heavier insulation reduces the workload and running costs of your equipment and prevents condensation caused by the temperature difference between the water and its surroundings — whether that is a garden cold plunge, a spa hot soak with plant-room recirculation, or a commercial wellness facility. It protects both the tub and the system connected to it.

Some customers add insulation to indoor installations too, and we are happy to accommodate that — though it is not necessary for standard indoor domestic use, hot or cold. Our standard build is more than sufficient for a regular bathroom.

Available on any tub in our range, in any colour. Thicknesses can be mixed across a single build where a project calls for it. Pricing is on application, based on your project.

    About Omnitub Deep Whirlpool Baths

    Design & jets

    Where are the jets positioned in an Omnitub Deep Whirlpool Bath?

    Entirely bespoke. We configure the jet layout around your body, your space and the way you actually bathe. No two systems are identical — that's why we don't sell off-the-shelf configurations. Tell us your shoulder span, where your back tension sits, and whether you want focused jets behind the lumbar or feet, and we engineer accordingly.

    Are the jets flush with the tub surface?

    Yes. Every Omnitub whirlpool ships with flush jets — no protruding nozzles pressing into your back. Honestly, we can't fathom why anyone designs them any other way.

    How many jets does each whirlpool come with?

    Depends on the configuration. Standard Deep Whirlpool layouts include 8–14 jets; Deep Seated Whirlpool Baths sit at 10–18 jets across the back, hips and feet. Bespoke layouts can go higher — get in touch and we'll quote based on your design.

    How it runs

    How does the run-dry system work?

    Pipework is angled so water drains completely after every cycle. A built-in blower runs after each use to clear residual moisture from the system. You'll never experience standing water in the pipework — no stagnation, no biofilm, no smell. It's the small things.

    How long does it take to fill a Deep Whirlpool Bath?

    Roughly 8–12 minutes from a standard UK domestic supply, depending on flow rate. The deeper soak (600–1200mm internal depth) means more volume than a high-street bath — the depth is the whole point.

    How much insulation comes as standard?

    Standard: 7-layer Omnigel built-up system — holds heat materially longer than acrylic or steel. Upgrade: up to 13 layers + 25–100mm of additional insulation, sealed exterior coat. The upgrade is essential for outdoor, commercial or cold-plunge / heat-recirculation use.

    Build, install & warranty

    Can the whirlpool be installed outdoors?

    Yes — with the insulation upgrade. Up to 13 layers plus 50mm core insulation makes the Omnitub Whirlpool rated for outdoor patios, spa rooms and commercial wellness installations. Spec the upgrade at order time so we build it in from layer one.

    What sizes do you offer?

    Over 30 standard sizes from 1050mm × 700mm up to 1900mm × 1100mm. Anything outside that is bespoke — give us your room dimensions, doorway widths and stairway constraints and we engineer to fit. Custom sizes carry no upcharge on the body; jet configuration adds the cost.

    What does the 30-year warranty cover?

    Body, gel coat, internal structure and seam integrity for 30 years. Whirlpool pumps and blowers come with their own manufacturer warranties (5–7 years depending on supplier). We handle warranty claims direct — no third-party hassle.

    Order & delivery

    How long from order to delivery?

    Bespoke whirlpool builds run 8–14 weeks depending on colour, jet configuration and whether the insulation upgrade is included. White stock-colour whirlpools dispatch faster where the configuration allows.

    How do you deliver something this big?

    UK: Palletways, kerbside delivery. International: Worldwide via our shipping network, live checkout pricing. We crate every whirlpool on a 2x 18mm plywood pallet with strapping — no transit damage in the 20-year history of doing this.

    • Holds heat for hours

      We filled it once and were still warm two hours later. The Omnigel layers make a real difference — way better than the acrylic we replaced.

    • Outdoor cold plunge

      Installed it as an outdoor plunge with extra insulation. Survived a Pennine winter and still looks brand new. The team's installation advice was spot on.

    • Bespoke colour match

      We sent them a paint sample and they matched it perfectly. The bath ties in beautifully with our bathroom palette — couldn't have done it with any other manufacturer.

    • Worth the wait

      Coloured tub took the full two weeks they quoted, but the wait was worth it. Delivery was on the date we chose at checkout and the driver was excellent.
