About this range

Deep Soaking Baths, Japanese Soaking Tubs & Plunge Baths In Stock

Explore the complete Omnitub range of deep soaking baths, Japanese soaking tubs and plunge baths — all available in stock for fast UK dispatch.

Every model is engineered around genuine immersion. Internal soaking depths range from 600mm in our standard deep baths to 1000mm in seated Japanese soaking tubs, and extend to 1200mm and 1500mm in our plunge and stepped immersion designs.

Unlike conventional baths that prioritise length over depth, Omnitub products are built for vertical immersion and full-body soaking. From compact rectangular formats to wide architectural designs, square immersion tubs and dedicated plunge models, this collection represents our full in-stock white range.

All white Omnitub baths are ready to ship. Bespoke colour finishes are available to order. Handmade in Britain and built for structural integrity, each model delivers depth-led bathing performance.

Use the filters above to refine by external length, external width and internal depth to find the exact immersion profile for your space.

 

What Is a Deep Soaking Bath?

A deep soaking bath is designed for immersion rather than extension. While most standard UK baths provide 400–450mm of internal water depth, Omnitub deep soaking baths deliver a true 600mm internal depth as standard.

The result is full-body immersion in a more efficient footprint, improved heat retention and a deeper, more enveloping bathing experience.

 

 

Japanese Soaking Tubs – 1000mm Seated Immersion

Japanese soaking tubs are built for upright immersion. With internal depths of up to 1000mm, they allow vertical full-body soaking within compact external dimensions.

Available in single-seat and two-person configurations, these models combine traditional immersion principles with modern structural engineering.

All white Japanese soaking tubs are in stock and ready to ship.

 

 

Plunge Baths & Deep Immersion Tubs

For extreme immersion, our plunge baths extend internal depth to 1200mm and 1500mm in stepped plunge formats.

These models are ideal for:

• Cold immersion

• Contrast therapy

• Wellness installations

• Compact vertical soak spaces

Plunge baths are designed specifically for immersion performance rather than reclined bathing, with reinforced structural design to support deeper water levels.

 

 

Rectangular, Square & Architectural Formats

The Omnitub in-stock collection includes:

• Rectangular deep soaking baths

• Wide architectural formats

• Square immersion baths

• Compact space-efficient tubs

• Social and multi-seat designs

Every model is built around the same depth-first design philosophy.

 

 

In Stock Deep Soaking Baths – Fast UK Dispatch

All white Omnitub deep soaking baths are pre-manufactured and available for immediate dispatch within the UK. No extended production lead times.

Bespoke colour options are handmade to order in Somerset with the same immersion performance and structural integrity.

Depth is not an upgrade here. It is the foundation.

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.

Pricing on application

Spec your insulation in one call.

Available on any tub in our range. Tell us your project conditions — we'll spec the right thickness, walk you through pricing, and confirm the build slot before you commit a penny.

  • Insulation thickness recommendation (25mm — 100mm+)
  • Project pricing with no commitment
  • Build-slot confirmed before payment
  • Direct line to the maker — not a call centre

Insulation is an optional upgrade — every Omnitub holds heat beautifully as standard and is complete without it. You never need to call to order; this is simply here if your build calls for extra insulation.
