TOP 3 Buyers FAQs:


How much does it cost to run a Lay-Z-Spa hot tub?

We estimate it costs around £7 - £10 a week* to run a Lay-Z-Spa based on average usage. We are continually developing our hot tubs to be as cost efficient as possible – for example every Lay-Z-Spa pump now includes an energy saving timer.

The Lay-Z-Spa pump heater unit is thermostatically regulated, allowing it to intelligently heat the hot tub to save on running costs, much like a central heating system. The heater will heat the water to your desired temperature and then switch off. It will then switch back on again once it falls a few degrees below this.

Our Lay-Z-Spas also come with a top cover and an inflatable inner disc to provide maximum insulation. We have a thick Lay-Z-Spa Floor Protector available as an accessory which provides added protection and insulation.

*This is based on feedback we have had from our customers (however is ONLY an estimate and does not take into consideration specifics such as electricity supplier and increase in frequency of usage). Figures are based the Vegas model, usage of 3 times a week for approx. 25 mins with 20 mins of Lay-Z-Massage including a 5 min interval. Wind-block and cover utilised.


What extras do I need?

Chemicals are the only essential extra thing that you need to buy when purchasing a Lay-Z-Spa. We recommend using Clearwater Chemicals as they are designed with Lay-Z-Spas in mind and they include easy to use instructions. We also offer Hot Tub Chemical Advice on our website for Clearwater products.

The Clearwater Chemical Spa Starter Kit is the best option for new hot tub owners.

We also have a range of Lay-Z-Spa Accessories available, from Drinks Holders and Floor Protectors to the Entertainment Station.

For added protection and insulation for the base of your Lay-Z-Spa, we recommend the Lay-Z-Spa Floor Protector.


 Is it best to leave the heater pump running all of the time or turn it on before using it?

In our experience is better to leave the heater activated, all of the time, if used regularly - say 3 or more times per week. We would recommend setting the spa at a temperature of say 36 / 38 degrees °C and then an hour or two before using, nudging it up to 40 degrees if desired.



Choosing which Lay-Z-Spa to buy:

Which is the strongest Lay-Z-Spa? 

All our Lay-Z-Spas are composed using both a vertical and horizontal I-Beam Construction, offering superior structural stability without compromising on comfort. This durable configuration allows the spa to maintain its shape regardless of how many times it is inflated or deflated.

All materials used for our Lay-Z-Spas have been sourced with quality and comfort in mind. Each material used is highly durable and offers superior strength.

  • The Tritech material is exclusive to the Lay-Z-Spa range, and consists of a 3-ply reinforced material with a polyester mesh core that’s encased in 2 layers of laminated PVC. The inflated walls of the following spas use Tritech: Palm Springs Airjet, Hawaii Airjet, Siena Airjet, Palm Springs Hydrojet, Hawaii Hydrojet Pro.
  • The Leatheroid exterior cover provides complete protection and additional insulation to the spas. The exterior of the following spas have a Leatheroid cover: Paris Airjet, Vegas Airjet, Saint Tropez Airjet, New York Airjet.
  • The complexity of the Drop Stitch material is what gives the Monaco Airjet its rock hard rigidity. The Monaco Airjet is the only spa to feature this amazing material in its inflatable walls.
  • The Rayon Coating offers supreme protection to the outer walls of the spas, making them resistant from punctures. The exterior of the following spas have a Rayon Exterior Coating: Miami Airjet, Havana Airjet.

Can cats puncture the Lay-Z-Spa?

If you are concerned about your cat puncturing your hot tub, then we recommend buying a Vegas or Paris model as these Lay-Z-Spa's have a leatheroid cover for extra durability.


Setting Up Your Lay-Z-Spa:

How easy is the Lay-Z-Spa to set up?

Very easy!

Lay-Z-Spa hot tubs are inflated by using either the air blower on the pump (Airjet models) or using the supplied electric air pump (Hydrojet models). Please refer to your instruction manual for specific set up information. This takes anything from around 5-15 minutes to set-up.

From there all you need to do is fill the Lay-Z-Spa with fresh water, give it a commissioning shock dose of chlorine and wait for it to heat up! It is fine to fill the hot tub with warm water from the beginning if you wish.


Where is the best place to set up my Lay-Z-Spa?

A smooth, flat, even surface that is capable of uniformly supporting the entire filled weight of your Lay-Z-Spa plus the weight of the users.

You need to consider having a power supply that is close enough for the cable to reach (approx. length of the cable is 7m) but also far enough away so that water cannot splash into the socket.

Also consider your surroundings: placing your Lay-Z-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.

Positioning your Lay-Z-Spa on an uneven surface can cause unequal pressure on one or other side of the hot tub which will increase the likelihood of your liner failing.


Can I use my Lay-Z-Spa indoors and outdoors?

Lay-Z-Spa's are suitable for use both outdoors and indoors. Whilst most of our customers set them up in their gardens either on a hard surface such as a patio or on their grass, a number of customers also set them up in a summer house, shed or garage. For use indoors, you should take particular time and care to consider factors such as drainage and ventilation.

For example, if there was a problem would water be able to drain freely without causing damage? The Lay-Z-Spa is likely to increase the humidity of any confined space it is placed within, how would this affect the chosen area? Have you fully considered the ventilation? Is the floor suitable to withstand the weight of the hot tub when full? Is the floor a level non slip surface? Does the electrical supply have an RCD? Lay-Z-Spa does not take any responsibility or accept any liability for the use of the Lay-Z-Spa in an indoor area, summer house or garage.


How long does it take to fill?

Your Lay-Z-Spa will usually take approximately 1- 2 hours to fill up to the recommended line (depending on your water pressure and Lay-Z-Spa model).

How long does it take to heat up?

This can vary greatly depending on the temperature of fresh water that goes into the hot tub, the ambient air temperature and which Lay-Z-Spa model you have (the higher the capacity of water, the longer the hot tub will take to heat up).

The Lay-Z-Spa Pump heats the water via a circulating pump and heats up at approx. 1.5-2°C/h (3-4°F/h) per hour.

In England in the Summer, it can take on average 6 - 12 hours.

You can fill your hot tub up with warm water (not boiling water from the kettle though!) if you want to reduce the time that you have to wait to get up to your desired temperature. Ensuring that the spa is well insulated and that the lid is on will also greatly help!


Maintaining Your Lay-Z-Spa:

Is it easy to clean & maintain?

The Lay-Z-Spa range of inflatable hot tubs are very easy to maintain and are all supplied with an owner's manual with maintenance instructions to help you get the best from your purchase.


How much will it cost to maintain and run an inflatable hot tub?

We estimate it can cost around *£7 - £10 a week to run based on feedback we have had from our customers (this however is ONLY an estimate and does not take into consideration specifics such as electricity supplier and increase in frequency of usage).

Our Lay-Z-Spas come with a top cover and an inflatable inner disc to provide additional insulation and we also have floor protectors, which can all reduce running costs of an inflatable spa.

As the Lay-Z-Spa heater is thermostatically regulated, the heater will only actually switch on to top up the temperature of the water to your desired temperature, once it falls a degree or two below this.

Therefore depending on the amount of use your spa gets, in our experience is better to leave the heater activated, all of the time, if used regularly - say 3 or more times per week. We would recommend setting the spa at a temperature of say 36 / 38 degrees °C and then an hour or two before using, nudging it up to 40 degrees if desired

*Figures based Spa usage of 3 times a week for approx 25 mins with 20 mins of Lay-Z-Massage including a 5 min interval. Wind-block and cover utilised.


Can you leave the pump running all the time?

We recommend leaving the pump on all the time, as this maintains the heat of the water and will mean that the filter is running as well.


Can I run the heater and the pump at the same time?

 Yes, with our latest integrated technology you can heat the hot tub, run the massage system and filter the water simultaneously using just the pump.


What should I do with my Lay-Z-Spa if I am going on holiday?Should I leave the filter running all the time?

If it's only for a few days, the pump, filter and heater can be left running. If you will be away more than 72 hours the pump unit will switch itself off. The water needs to be continuously circulated so it would be advisable to arrange for someone to go in and reactivate it. Otherwise, we would advise that you drain and clean down your Lay-Z-Spa, and re fill it when you return.


Is it easy to get accessories and spare parts?

Yes, you can order spare parts and accessories directly from


Electricity & Safety with Your Lay-Z-Spa:

What electricity supply do I need to run my Lay-Z-Spa?

Our hot tubs run on a UK standard 13amp/240V electrical supply. You should always use a grounded socket with RCD protection. All of our pumps come with a built in RCD unit as a safety measure. The socket that the hot tub is being plugged in to should be grounded and at least 4 metres away, at a height of at least 1.2m from the ground. We recommend getting a qualified electrician to install a grounded outdoor waterproof socket with RCD protection (this should always be done by a qualified electrician).


Can I use an extension lead?

No, extension cables cannot be used with Lay-Z-Spas. The Lay-Z-Spa pumps come with a 7 metre cable which is usually sufficient for customers to reach their nearest grounded socket with RCD protection. If the cable is not long enough, we recommend getting a qualified electrician to install a grounded outdoor socket with RCD protection. The socket that the hot tub is being plugged in to should be grounded and at least 4 metres away, at a height of at least 1.2m from the ground.


What is an RCD?

All of our spas are fitted with an internal RCD (residual-current device) this is a cut-out device in the event that water comes into contact with the electrical supply to your inflatable hot tub.


Chemicals, Water Health & Your Lay-Z-Spa:

How do I maintain my Lay-Z-Spa water on a daily basis?

In order to maintain clear, clean and healthy water there are some day-to-day / regular tasks that you will need to undertake:

1. Water Filtration / Circulation

It is a combination of circulating the water through the filter cartridge to collect suspended dirt and oils, together with good chemical water treatment that helps you to maintain clear, clean and healthy water.

Whenever the Lay-Z-Spa's heater is turned on, the filtration function is automatically activated. If you wish, it is possible to activate the filter on its own, to keep the water circulating but not heating.

2. Water Testing & Daily Adjusting of Chlorine & pH Levels

It is essential to test the water every time before getting in. Chemicals will still get used up and will be constantly changing, even if you haven't used the spa. We recommend testing the water 1-2 hours before you plan to use it to give you time to make any chemical adjustments if required.

When it comes to water testing we recommend using Clearwater 3 way Dip Test Strips. Using Clearwater 3 Way Dip Test Strips you are able to quickly and accurately assess your spas water conditions and make adjustments to the chemical levels as required.

Clearwater Dip Test Strips test the necessary 3 chemical levels that you need to monitor to maintain safe, clean and comfortable water:

      1. Free Chlorine
      2. pH Levels
      3. Total Alkalinity (TA)



Ideal Reading



Free Chlorine

3-5 ppm*

This refers to the amount of chlorine in your spa that can sanitize or disinfect the water, keeping it safe for users.

It is safe to bathe in the water when the chlorine level is 5ppm or less (ideal level is 3-5ppm).

Too little chlorine results in cloudy water and insufficient sanitization, providing a breeding ground for algae and bacteria which may be hazardous to health.

Too much chlorine may result in skin and eye irritation.

Clearwater Chlorine Granules


Clearwater Mini Multifunction Tablets

pH level

7.2 - 7.6

pH is a measure of the acidity or alkalinity of your spa water.

The pH of spa water tends to increase during use, eventually becoming too alkaline. This results in formation of scale, cloudy water, skin and eye irritation and causes chlorine to be lost through evaporation.

Alternatively the pH level of your spa water may drop below the recommended range, becoming too acidic. This may result in corrosion, skin and eye irritation and reduces the sanitizer efficiency of chlorine.

Clearwater pH Minus to decrease


Clearwater pH Plus to increase


Total Alkalinity

80 - 160 ppm*

The total alkalinity (TA) is a measure of the capacity of your spa water to neutralize the water when it becomes too acidic.

When the total alkalinity is within this recommended range, it prevents rapid changes in the pH of your water.

If the TA is too low the pH will become unstable and increase or decrease rapidly. If the TA is too high, the pH of your water will become difficult to adjust, the water becomes cloudy and chlorine treatment will be less effective.

This is unlikely to fall outside of the normal parameters.

If you do find that the TA is too high, take out some of the pool water and replace with fresh water, continuing until a normal TA reading is achieved.

If TA is too low, add small increments of pH increaser.


How often do I need to change the water?

This really varies depending on how effective you are at maintaining your water using a chemical maintenance regime.

It is recommended that Lay-Z-Spa water is changed regularly, and at least once per month. The frequency of water changes should reflect the degree of use of the pool, as well as the results of chemical testing. If chemical levels have fallen far outside the normal ranges, it is recommended that the water is completely replaced and re-treated.

It is important to shock dose your water on a regular basis and you will find it will extend how long you can use the water for.


Do I need to use Chemicals and why?

Yes, regardless of how often or long you plan to use your hot tub, it is essential to treat the water in your Lay-Z-Spa. If you left your Lay-Z-Spa water without any treatment, it would soon become uncomfortable, unclean and potentially dangerous even just to passers-by.

Chemicals are a highly effective way to treat your Lay-Z-Spa, as they eliminate any harmful bacteria that can grow in warm water. (It doesn't take long to get used understanding and using chemicals in your Lay-Z-Spa. Before long it will become second nature to you.)


Do I have to use chlorine in my Lay-Z-Spa?

Chlorine or bromine is a powerful sanitiser which is necessary to keep your hot tub clean and healthy. As a body of still water, a hot tub runs the risk of becoming stagnant and dangerous if not treated properly. Therefore it is essential to use something to sanitise your water.

However, the new Lay-Z-Spa Hydrojet and Hydrojet Pro includes the Clear Soft Water Treatment System which generates chlorine from pure spa salt. This technology, often known as a "Chlorinator" or "Salt Water Cell" uses electricity to break the salt up into chlorine molecules. Because the chlorinator keeps renewing the supply of chlorine, the dose level can remain relatively low. You also won't get that "chlorine smell" that is created by chloramines.

While a chlorinator will generate chlorine from salt water, it is still highly advisable to use chlorine to shock does your spa or pool regularly and maintain good water health.

Although you can't maintain good water safety and hygiene without a sanitiser like chlorine, it is possible to use lower levels, with occasional shock treatments, using the ClearSoft Water Treatment incorporated into the NEW Hydrojet hot tub models.

The Weather & Your Lay-Z-Spa:

Can I use my Lay-Z-Spa in the winter?

The Lay-Z-Spa should not be setup or left out in temperatures lower than 4°C (40F). However a hot tub in the winter is every bit as enjoyable if not better on a cold crisp starry evening. So if you wish to use your hot tub in winter always make sure it is protected either on a raised platform in a sheltered or covered area and remember ambient temperature should be regularly checked so that it does not fall below 4°C (40F) as water could freeze within the pump and cause irreparable pump failure.


Can I leave the pump out in the rain?

The pump is splash proof not waterproof, so in periods of heavy rain we suggest either covering the pump, or detaching it and bringing it under cover.

How do I store my Lay-Z-Spa in the winter?

Simply drain, deflate, clean thoroughly with a mild non-abrasive cleaner, rinse thoroughly, dry and all should go back into the box for storage. Please store the Lay-Z-Spa in a dry, moisture free environment that has an ambient temperature of well above 4ºC.
