General Questions

How Do I Choose The Right Hot Tub For Me?

There is lots to consider in selecting the right hot tub for you; your height, the number of people using the hot tub on a regular basis, even down to the style of massage you’re looking for. We’ve built a huge range of hot tubs so we can almost guarantee the right hot tub for you is in there! 

Check our Hot Tub Buyers Guide for the full details or give the sales team a call on 0115 954 8888 and they will be able to advise on the best options for you.

How Much Will It Cost To Run?

We would never try to tell you exactly how much your hot tub is likely to cost to run. There are lots of different factors that affect the running costs – regularity of use, ambient temperature, electricity tariff. 


You may see claims from some companies of £1 per day, but this is likely being calculated only on the cost of keeping the water hot, without any initial start-up costs or running the jet pumps. In other words, not enjoying the hot tub! This can be misleading as using the hot tub will obviously exceed this and it is impossible to determine the exact cost without knowing how often the hot tub will be used. 


For estimates on the different running cost and how to run your hot tub most efficiently, check out our running costs page. Then speak to our sales team, where we can have an honest conversation before you purchase to advise more thoroughly.

How Can I Reduce My Hot Tubs Running Costs?

Firstly, consider the location of your hot tub; if it is located in a cold, exposed area with lots of windchill, it will take more energy to keep the water at the correct temperature than a sheltered warm area.


Keep the hot tub at a set temperature; it may feel more efficient to reduce the water temperature and reheat before use. But if you are using the hot tub regularly, it’s likely to use more energy re-heating the water than keeping it at a steady temperature.


Invest in a Spa Protector; this thick, layered cover adds an additional layer of insulation to the hot tub while offering protection to the hot tub cover.


Choose a hot tub with the right size and specifications for you; for example, a larger hot tub with more water, will inevitably have a higher running cost. But for large families or if you enjoy your hot tub with friends, this is likely outweighed by the enjoyment and entertainment you’ll gain in a larger tub. The Sales Team can advise on tubs with additional insulation and highly efficient jet pumps which can help reduce the energy requirements when the hot tub is in use.

Is My Hot Tub Insulated?

We offer a range of hot tubs with double, triple or quadruple insulation along with the insulating lid.


Insulation Included: water resistant polyurethane foam on the acrylic shell making sure the heat stays in your water. Side panels and hot tub base also act as a layer of protection against outside elements.
Enhanced Insulation: more energy efficient, including the standard shell and cabinet insulation, and also a foil reflective layer on the skirting panels and base of the hot tub to help keep the heat in.
Triplex Insulation: includes the standard shell insulation and protective side panels and base, plus the foil reflective layer on the panels and base, and a this foam insulation in the panel cavities, underneath the foil layer. This keeps the elements out and holds as much heat as possible in the water and base.

The insulation included in each hot tub is detailed in its specification. The more insulation, the lower the running cost compared to a hot tub of the same size and with the same use.

We do get asked why we don’t completely fill the inside of the hot tubs with foam insulation. This can reduce heat loss but it means if there is a problem with a part or pump in the future, it’s almost impossible to access and repair it. A simple leak in a jet or pipe-joint can create huge maintenance problems. Our hot tubs are designed to last and be enjoyed for years. Part of that is ensuring access to be maintained and that easy repair after a few years of use doesn’t end with you purchasing a brand new tub.

Do You Have A Showroom?

We have four showrooms open across the UK: Nottingham (our flagship showroom), Chesterfield, Edinburgh and Cardiff, all located with easy access from the motorways and with ample free parking. 


No appointments are needed but opening times vary by location so check our Showroom page for all the details.

Where Are Blue Whale Spa Hot Tubs Made?

Blue Whale Spa is the UK’s leading manufacturer and supplier of hot tubs, being the only UK company who manages the entire process from design and production to sales, delivery, installation and after sales, with thousands of satisfied customers. 


We design the hot tubs in the UK, for the UK market and weather(!), which are manufactured in our own facilities in China, which allows us scrutiny over every stage in production, sales, installation and maintenance. Extensive testing, including wet testing, is conducted on every hot tub before it leaves China to ensure the quality is maintained.

Do I Need Any Accessories or Extras?

Your hot tub already includes an insulating cover, steps and a free filter, so the only essential extra is the chemicals to keep the water hygienic. 


We recommend using our Starter Chemical Pack as they are designed to protect your hot tub and they include easy to use instructions. Alternatively the Advantage Chemical pack is a really cost effective option. 


We also have a range of Blue Whale Spa Accessories available, from Testing Strips and Filters to Cover Lifter.


For added protection and insulation, we recommend using our thick Blue Whale Spa Spa Protector.

Can I use my hot tub in the winter?

Our hot tubs are designed to be used all year round, with insulation and powerful heaters so they stay hot in colder weather. One of the best times to enjoy a hot tub is a cold crisp evening, the water keeps you warm and makes a fantastic contrast to the cooler air; there’s a reason saunas were invented in Finland. 


However, if you do choose not to use your hot tub in winter, follow our winterization guide or book a winter shut down, to ensure you close it down properly without risking damage.

Delivery and Installation

What Is The Best Place To Set Up The Hot Tub?

A smooth, flat, structurally sound, level, even surface that is capable of uniformly supporting the entire filled weight of your new hot tub plus the weight of the users. A filled spa can weigh a great deal. Make certain that the location you choose can support the weight of your filled spa.


You need to consider having a power supply that is close enough, but also far enough away so that water cannot splash into the socket. Allowing water into the equipment compartment can damage the electronics, or may result in tripping your house’s circuit breaker or RCD.


Leave yourself easy access to all circuit breakers and RCD’s. Also, leave access to at least the entire front of the spa (the removable panels provide access to the spa’s equipment) for periodic spa care and maintenance.


Also consider your surroundings: placing your spa near a wind break such as a fence will help to reduce wind exposure, helping it to retain more heat and in turn help to reduce your running costs. You should also consider where you will drain the water when required.

Where Do You Deliver?

All Blue Whale Spa Hot Tubs include free UK mainland delivery and installation.

All off-mainland purchases need to be organised with an independent courier for separate delivery.

What Access Do You Need To Install My Hot Tub?

Your hot tub will be delivered on it’s side on a hot tub sled so we need a minimum of 3cm on either side of the hot tub to access your location. This includes any potential obstacles, such as drain pipes, gates and steps. 

The full delivery details are available on the Site Preparation page and we will be in touch to go through these as part of your pre-delivery checks.

What Do I Need To Do Before Installation?

Ahead of the installation, we ask you to check the delivery route and complete our Pre-Delivery Checks. This includes sending photographs of the delivery route, from street to the final position, so the engineers can be sure the hot tub can be delivered safely. 


The electrical installation should be complete ahead of the delivery date and a armoured cable provided to connect your hot tub to the electrics. We also recommend ensuring you have a hosepipe handy to fill up your hot tub.

Can you fully install my hot tub?

Included in the price of your hot tub is our “Delivered and Installed” service which includes delivery, positioning, wiring into the control box and your pre-installed isolation switch, and an onscreen demo how to fill with water, maintenance and chemical talks, and instructions of function.

If you wish to have our team fill up your hot tub with water, commission and test everything, give you a detailed chemical talk, basic instructions on maintenance and feature and function demonstrations, you can upgrade to the “Comprehensive Delivery Service” for just £199. Call our team on 0115 954 8888 to find out more.

All deliveries are carried out by our own team of directly employed, highly skilled and experienced engineers.

How Quickly Will My Hot Tub Be Delivered?

We have an extensive stock of hot tubs at our local showrooms so, if your hot tub is in stock, delivery can be within two weeks.

Alternatively, if you are still preparing the site then we can usually hold your hot tub until delivery.

Electrical Requirements

Do you offer ‘plug and play’ hot tubs?

The short answer is no, as non of our hot tubs come with plugs attached to their electrics. We offer 13amp hot tubs which are able to be powered with a normal outdoor RCD plug socket, so require less electrical set up. An RCD is simply a safety cut out device for the electricity supply and is required to be in the outdoor socket for 13amp hot tubs or in the consumer unit for 32amp hot tubs. This is not included in the hot tub itself. 

We do require you to provide a 2.5mm armoured cable long enough to reach from the socket to your hot tub (Plus an extra metre) and have a plug on one end. The engineers will wire this into your hot tub during installation. 

We also offer 32amp hot tubs and 40am swim spas. 

What electrical set up is required for my hot tub?

The electrical details are available on the site preparation page and will also be emailed to you ahead of the installation date.
