The Duke Hot Tub 

5 star value = 2 Loungers & 3 Seats

The Duke hot tub offers 5 seats within its 210 cm x 210 cm frame.

Just like all HTS models, the Duke is complete with a multiple layered acrylic shell under which a high density insulated foam cradled by a strong stainless steel frame for extra protection & support lie.

The hydrotherapy is delivered courtesy of 29 finely tuned Hydro Design jets fuelled by a 1 x 3HP massage pump. The Duke has a ratio of jets per HP of Just 9.7.

The Hydro design jets on the Duke are a combination of directional & swirl jets to provide the best relief & massage for the user.

The hot tub is reliably & efficiently organised by a spa system & 2KW(13amp) / 3KW(32amp) heater that is designed by the world respected Balboa Water Group.

Water diverters are unique on the Duke hot tub as they enable the user to divert water in certain areas of the hot tub when there are only a few users, therefore all the power is transferred to a single area, hence greater hydrotherapy. 


Extra features of the Duke consist of water pressure adjustment, water diverter valves, pure water ozone disinfection, twin filtration system, LED surround lights, LED fountain & Bluetooth audio for creating the perfect mood.

The Duke also has enhanced insulation on both hot tub cabinets & the strong ABS base.

Easy access cabinets together with an advanced drainage system making the service time quick & easy.

Duke is a versatile model with 2 loungers and 3 seats within is 210cm x 210cm frame, it's also powered by a 32 or 13 amp along side with added flexability & ease for both business & domestic owners.

The added depth to the Duke also guarantees comfort for all users

Our multi-layered acrylic shell is a fusion of marine grade resin combined with fibreglass alongside pure vinyl ester finished with an acrylic outer which is durable & thick & available in a multitude of premium colours.

Layer 1 – Top Acrylic Finish

Layer 2 – Pure Vinyl Ester

Layers 3-4-5-6 – Marine Grade Resin Combined With Fibreglass.

The shell is then coated in a high density foam for added strength & insulation ( see above )

  3. Protective Inner Lining

  5. Aluminium Alloy Frame
  6. Corrosion Proof Zip

Made from a senior grade PU, the HTS spa cover is resistant to harshness of the winter plus warmth of summer with particular resistance to Heat, Water & UV. Inside The PU material lies the high density EPS foam.

Expanded PolyStyrene (EPS) insulation is lightweight, rigid with closed cell insulation which is strong, stable, energy efficient & thermal resistant.

The EPS also has inertness to chemicals.

To give the foam added strength an aluminium alloy frame is also inserted to inside the cover to keep shape and strength.

Each cover has secure clips with locks for wind resistance & safety, plus handles which aid in the movement of the cover.

The spa cover tapers to allow water to drain away with the size of 9 to 12cm which compares favourably alongside most spa covers.



Enhanced Insulation

The hot tub range uses a closed cell high density foam to insulate the base of the shell. This keeps the heat within the hot tub & helps save money on energy costs. The high density foam also increases strength to the structure.

All hot tubs are built with stainless steel frames as well for extra stature and quality.


Twin Water Filtration

Filtration is used to separate unwanted particles from the water to maintain a smooth flow of water.

Contaminated / dirty water would hinder the water flow of the spa & cause issues with the function of the hot tub.

Filtration is therefore important to keep the water clean plus aid the smooth running of the hot tub

Our programmable filtration system allows full control of the filtration process with the twin filter system of the Duke working in tandem to prevent the passage of any unwanted solid particles.

The filter is easy to access, even easier to remove & replace to enable easy maintenance.


Balboa Control Panel

The Balboa Water Group design & product the best spa systems in the world.

The Duke is controlled via a Balboa top panel, heater & internal control board.

Easy to use & efficient, the control system also features programmable filtration plus economy modes to maintain complete control of the Spa.


Award Winning Hydrotherapy Jets

The Duke has a wide variety of hydrotherapy jets, specifically designed & positioned to deliver massage & relief.

Each jet is lined with a stainless steel surround for added luxury & distinction.

Hot Tub Suppliers are British Gold Award Winners in 2016, 2017 & 2018 of Hot Tub Health Benefits which only illustrates the quality of the jets plus pumps in this hot tub range.

The Duke hydrotherapy experience includes specially positioned massage jets for back, shoulder, feet, legs, hamstring & calf.


Balboa Bluetooth Audio

The most advanced Bluetooth system to date, the marine BBA2 system is concealed within the hot tub and can be connected via any smart or android device.

Designed by Balboa Water Group, this patented design delivers a crisp & clear sound with same efficiency & reliability one would expect from Balboa.

The player can also be controlled via the control panel of the Revive Microsilk hot tub with the artist & song selection displayed on SpaTouch panel.

Easy to connect & easy to use, the BBA2 is the only audio which could befit our range of Microsilk hot tubs.


LED Ambient Enlightment

LED ambient illumination is a feature on all of the models in the range of hot tubs.

These extras create a relaxing yet sophisticated atmospere when resting in the hot tub.

From waterfall to fountains, from surround lights to prism spot lights - these features are mulicoloured to create a visibly strong light show both during the dayime or evening.


Water Divertors

Ensure you enjoy the maximum hydrotherapy by using the Dukes water diverters to direct water to where you are sitting for increased power & performance.

The diverters deliver complete control on the distribution of water with ability to direct water to your location in the hot tub
